The display on the Priora dashboard does not work

The year of installation is not indicated. Maybe I'm wrong, but in my opinion the backlighting system has nothing to do with either the processor or the micro. just two pins + and - from them there are tracks on the board to light bulbs. unless, when programming, the processor emits a laser beam and cuts the track, or perhaps the winder somehow disrupted the track.

Yes, I have the same opinion. Artem, it seems to me that the person simply unsuccessfully inserted new light bulbs into the “sockets”, they brought me a panel from Priora AP in which, after replacing the lamps, half did not light, I began to figure it out, as a result, when the person inserted the light bulbs into the sockets, all the “guts” were in hushed them up. ))))

Tuning and replacement of the instrument panel

If you want to tune or replace the instrument panel, then you will probably find the instructions for removing and disassembling the panel useful.
The tuning procedure involves removing and disassembling the shield, we will discuss this in detail below. Tuned tidy of a Priora car

So, to tune and replace the device, follow these steps:

1. First of all, to carry out replacement or tuning, it is necessary to dismantle the tidy, having first removed the lining and disconnected all the fasteners. You also need to disconnect all wiring harnesses. If you are installing a new dashboard, then simply replace it.
2. To carry out tuning, you need to remove the arrows, first disassembling the device. To prevent the panel from scratching, place thin cardboard or a plastic card under the arrows.
3. The next stage of tuning will be to dismantle the panel cover; to do this, it needs to be separated from the glass base.
4. So, let's proceed directly to tuning. If you want to tune the backlight, then the green coating must be removed; for this, use a stationery knife. Then you can take a plastic bag of any color, cut a small piece out of it and place it on the back of the trim. For proper tuning, cellophane must be glued.
5. Simple lamps are not suitable for good illumination; it is better to use LED indicators. If you decide to install tape, then it should be glued along the entire perimeter of the scale. The pieces glued to the instrument cluster must be connected to each other with thin wires, after which the power wire is removed.
6. Another step is to disassemble the display. It is necessary to remove the light filter from this element or replace it with another one. The filter can be of absolutely any color, depending on what kind of tidy light you want to get.
7. The final stage will be the installation of all arrows and components on the control panel with further connection to all the necessary wires (video author - Kirill Zhukov).

In what cases is it necessary to remove the instrument panel?

Dismantling the Priora tidy is required for tuning or replacing burnt out lamps. The VAZ 2170 is a modern model, so there are not many fastenings on the panel. To disassemble you will need a set of screwdrivers. Don't forget to turn off the negative battery.

The process begins with removing the mounting block. To do this, you need to turn the latches on the fuse cover and then remove it;

Panel malfunctions: signs and causes

What are the errors on the instrument panel of the Lada Priora
? What malfunctions can occur in the operation of the control panel:

1. The backlight does not light up. There may be several reasons - damage to the device’s power supply circuit, a short circuit in the system, failure of the control panel. But one of the most common reasons in this case is the burnout of the safety device. The marking fuse F10 is located in the mounting block; it must be checked first.
2. The sensors do not work - the arrows on the speedometer and tachometer do not rise. The reason may be a bad signal coming from the speed sensor or crankshaft sensor to the dashboard. It is necessary to check the electrical circuit for breaks. Much less often the problem lies in a failed sensor.
3. The controller for the volume of gasoline in the tank and the engine temperature do not work. As in the previous case, the cause of the malfunction may lie directly in the sensors themselves. The fuel volume controller is located in the tank with the fuel pump, and the coolant sensor is located in the cylinder head. Before replacing, we recommend checking the quality of the connection and contacts - perhaps they are simply damaged or oxidized, as a result of which the sensors do not work. The reason may also be a damaged electrical circuit; in this case, you will need to check the wiring.
4. It happens that the dashboard as a whole works correctly, but the controllers transmit incorrect information. The reason may lie in the performance of the processor or a short circuit in the wiring. Sometimes the problem lies in bad mass.
5. The backlight is partially not working. Most likely, the reason lies in the burnout of the lighting sources; they will need to be replaced (the author of the video is the channel In Sandro’s Garage).

Air conditioner fault codes on Priora

If the air conditioner light on a VAZ Priora is blinking, the malfunction can be determined based on the error code read from the on-board computer.
Depending on the code, the causes of the malfunction are as follows: 9338 - the temperature sensor located in the passenger compartment is faulty; the sensor wire is broken or the connector is oxidized;

9337 - the temperature sensor located in the cabin, or the wire going to it is shorted to ground;

9348 - the sensor recording the ambient temperature is faulty, or the electrical circuit for its connection is broken;

9347 - the sensor circuit that records the ambient temperature is shorted to ground;

9378 - the evaporator sensor is faulty or the electrical circuit going to it is broken.

9377 - the electrical circuit of the evaporator sensor is shorted to ground;

9358 - the wire coming from the radiator sensor of the heating system is shorted to ground;

9412 - short circuit in the electrical circuit of the air mixer micro-reducer;

9413 - the electrical circuit of the micro-reducer is broken;

9420 - the electrical circuit of the micro-reducer winding is closed;

9426 - the electrical circuit of the micro-reducer winding is broken;

9440 - the power supply circuit of the additional resistor that regulates the speed of the heater fan is broken;

9860 - overvoltage of the on-board network;

9861 — low voltage on-board network;

9607 - malfunction of the air conditioning system controller.

Standard instrument panel - article number and price

Why is the exclamation mark on the instrument panel of the Lada Priora and what to do?

The original car tidy exists in three types.

• the first is an option for a pre-restyling car;
• the second panel is for a restyled car;
• and the third is the “Lux” option for the restyled one, which has become faintly similar to all previous torpedoes.

Each of them contains standard elements such as a tachometer, so their functionality does not decrease. . Who wants to do tuning of the instrument panel, this option is for them.

Priora first generation

The instrument cluster for the first generation Lada Priora received catalog number 2170-3801010. Cost – about 6,000 rubles. Everything is standard with it - from left to right there are four arc scales with red arrows: odometer, speedometer, coolant temperature, fuel level. Below the speedometer there is a small on-board computer display, and above the arches are all the indicators, including the direction indicators.

Priora 2

For the Priora “Lux” variation there are two more “subtypes” - with or without a CAN bus. Different subtypes were made so that the panel could be connected to any car. Catalog number – 2170-3801010-50 without tire, 2170-3801010-60 with tire. It is distinctive in that it contains an elongated display with a screen that can highlight the navigator.

The catalog number of the combination for the “Norma” assembly is 21720-03801010-20. Cost – 6,500 rubles. Like the “Lux” version, it received a brighter speedometer and odometer, and the coolant temperature along with the fuel level indicator is hidden at the bottom of the speedometer and odometer. The base will not create a route on the display, but will show all the information in color.

Guys, help) the whole tidy is on, only the speedometer is not on, you put the lights from the speedometer in another place, they work, and all the working lights on the speedometer do not light up, what could be the problem? Where and what to see or change? If you have the skills, then disassemble the device and look for a burnt out track or restore an erased contact pad.

13 - contact - white - instrument lighting (remove the white wire from the block, instead apply it from the ignition switch or the D+ signal from the generator - the instrument will be illuminated when the ignition is turned on or when the engine is running. The indicator - "gauge" will work normally, as usual when incl. dimensions)

The entire instrument panel periodically began to go out (if you turn on the turn signals, the indicators turn on, but the rest of the panel is still without light), and all other indicators too. The backlight comes from the electrical package controller, contact X2-2 (white wire), then branches somewhere in the harnesses on several wires, diverging to all places, including the dashboard lighting. To begin, pull connector X2 of the electrical package controller several times (it is 20-pin), maybe the contact is bad, or you can turn on the backlight, wait until it stops working and use a needle to measure the voltage on the specified wire.

How to find X2-2: https://xn—-8sbabr6ahc3e.xn--p1ai/images/LADA_Priora/Tuning/Other/podkluchenie-antiradar-priora/mus2.jpg

If the car is new and the Central Body Electronics Unit is installed instead of the electrical package controller, then everything is simpler - the backlight takes its origins in the lighting control module, pin 58b, the wire is also white.

Hello comrades. I have the following problem: the lights on the instrument panel, heater knobs, heated glass, cigarette lighter are not on, but the lights on the power windows and MUS are on. In addition, the left side of the lights does not light up, the low beam lights up normally. What can non-burning elements have in common and where to go?

Added after 7 minutes and I was also mistaken, the MUS is not lit either

Good advice. Need to try. Three hundredth like from me.

I have a problem. The backlight does not light up. all the lights are on, the handbrake, headlights, turn signals, everything at the bottom and the on-board computer. They changed the plug, cleaned the case. I was changing a burnt out light bulb. Is this how it should be? where to go

I get a ringing sound but the dash doesn't light up, what could be the problem?

Install factory diodes often burn out

It is advisable not to get super glue on the wires, they become stony and the insulation breaks easily

In general, what can I say about these? We understand that when something breaks down, and a chip breaks in your hands during dismantling, then in the end you need to replace the chip, and disassemble the panel itself, and fix this chip on the other side, on the panel itself.

And tell me on the VA 2112 with Europonel how the contacts are located, too, when I turn it on it lights up and then goes off, and I haven’t figured it out every morning yet

very helpful, thanks

You're welcome! Glad I could help)

My lights are partially dimmed and some are shining normally, why is that?

@Stories from the Garage I changed the lamps the same way

It's time to change the light bulbs, I think)

It happened the same way, after a week everything stopped burning altogether

Hello, my backlight is on, it may be on, it may go out, then it will glow

Hello, same problem only on gazelle

I think the reason is similar, you need to look at the pinout of the instrument panel of your car. Perhaps you just need to tighten the contacts on the light bulbs, or perhaps replace them altogether.

My cigarette lighter shorted, and the backlight on the dashboard stopped working, everything else in the dash works, all the sensors show everything, the fuses for the backlight are intact, what’s the problem?

If the previous ones are intact, then there are few options left. Or something was damaged in the instrument board, which is unlikely of course... You can check the instrument panel separately, right at home from the 12 volt unit, you will find how to do this on YouTube. There is nothing complicated, if the backlight works while in your hands, then there is a problem somewhere in the car. It remains to check (sort of) contact 18 from the instrument panel block, which is responsible for illuminating the scales; if not, the light control unit needs to be replaced (the thing that turns on the headlights regulates the instrument panel lighting :) )

Only the backlight does not work

@Stories from the Garage all the lights work, only the backlight, check f7 and f20, for the backlight and cigarette lighter, they are intact

“Intact fuses”, did you check visually or did you install new ones and there was no result? If visually, try changing two fuses F10 and F13. If not, then it was probably damaged in the light control unit. Try it as a replacement.. Do the interior lights and side lights come on or is it just the license plate light?

Additional block

Additional relays are mounted on a bar and located under the dashboard, near the front passenger's feet. To get to them, you need to remove the right tunnel lining. Next to the additional relays is the electronic engine control unit (ECU).

If its connector interferes with access to the relay, disconnect it by first removing the negative terminal from the battery.

Circuit breakers

F1 (15 A) – main relay circuit, starter blocking.

F2 (7.5 A) – power circuit of the electronic control unit (ECU).

F3 (15 A) – electric fuel pump. If the fuel pump has stopped pumping (this can be determined by the absence of a sound when the ignition is turned on), check together with relay K2. There may also be problems with the immobilizer, it blocks the pump, see information about F20. If the wiring, this fuse and the relay are good, most likely the fuel pump itself has failed. To remove it, you need to disconnect the battery, remove the rear seat cushion, unscrew the cover, ring and fuel hoses, then carefully remove the entire fuel pump.

K1 – main relay.

K2 – electric fuel pump relay. See above about F3.

Additional mounting block Priora

• F1 (15 A) – main relay and starter interlock circuit fuse;
• F2 (7.5 A) – fuse for the power supply circuit of the ECU (controller);
• F3 (15 A) – Priora fuel pump fuse;
• K1 – main relay;
• K2 is the place where the Priora fuel pump relay is located.

Attention! The relay and fuse diagram may differ depending on the configuration and production date of the vehicle. Current diagrams of the mounting block are presented in the operating manual for the date of manufacture of the vehicle (download from

site).

Let us remind you that on our website you can find detailed instructions for repairing the Lada Priora with your own hands.

Here we connect: 1) Speed ​​control, connect the white wire to the gray wire (pin 28 of the dashboard connector) 2) Ignition, connect the yellow wire to the orange (21 pin of the dashboard connector) 3) Dimensions connect the blue wire to the yellow (pin 7 of the dashboard connector)

Next we are interested in the mounting block, on the left under the panel, namely K7 - the relay for the high-beam headlights.

A mass is attached above the mounting block with a bolt.

We unscrew the screw from the bottom and take out the mounting block from the panel; we need the relay on the bottom left.

1) Connect the red constant plus wire to the pink wire going to the high beam relay. 2) The green wire in our case to the white-green wire going directly through the fuses to the lamps

What we end up with: 1) When autostarting, the lamps do not light up. 2) The lamps light up smoothly when you start moving. 3) When parked for a long time, the headlights first dim by 50%, then turn off. 4) When the headlights are turned on, the lighting goes into normal mode and the DRL turns off.

The dashboard contains the following parts, without which the car would not function:

• external lighting controller;
• switch for turning and lighting headlights;
• signal regulator;
• instrument cluster;
• wiper regulator.

Block in the engine compartment

The power fuse box is located in the engine compartment under the hood, near the left strut support. To get to it, you need to open the lid by prying the latch.

1 (30 A) - engine control system circuit. If there are problems with the electronic control unit, short circuits or other malfunctions, this fuse may blow out.

2 (30 A) - vehicle on-board circuit. 3 (40 A) - vehicle on-board circuit.

4 (60 A) - generator circuit.

5 (50 A) - electric power steering circuit.

6 (60 A) - generator circuit.

In case of any problems, it is important not to panic, to think soberly and logically. The most important thing is to diagnose and establish the cause of the breakdown.

If you don’t have enough experience or nerves, it’s easier to sign up at the nearest car service center if it has a competent electrician.

A slight blinking is normal. The masses would most likely give themselves away - the instrument would indicate overheating and the window regulators would barely raise the glass

Most of all it looks like a mass. Only she can do this. You can try changing the BUS if it’s a complete dead end. Maybe he's dying.

Electronics control unit. It is located in the middle of the dashboard in the leg area.

There was such a topic on Prior. Replace the capacitor that is in the generator and you will be happy. It acts as a filter against interference that the generator creates.

Or maybe the ground terminal, which on the engine should be cleaned first?

try. This happened to me because of the air conditioner

I didn’t write about the air conditioner, but about the capacitor

everyone does it, including me

My backlight on the boletus screen only blinks, and then only when the turn signal is on, has anyone encountered this?

When I turn on the turn signal, this is also noticeable. and when there is an emergency signal, it seems normal

the same bullshit, if you solve the problem please write

The same nonsense, the generator and battery are new.

Somewhere the ground wire is poorly fixed, you should contact an electrician. I think a competent specialist will quickly find...

Removing the instrument panel

To remove the shield you will need a flathead and Phillips screwdriver.

Unscrew the two top screws (as shown in the picture), then carefully remove the panel under the steering column. It is held on top by clamps, and on the bottom by 3 fasteners that just need to be turned.

Under the panel we see 2 more self-tapping screws for fastening the shield; we also unscrew them. Now lower the steering wheel to the lowest position and remove the plastic cover of the shield.

Now all that remains is to unscrew the two screws holding the dashboard itself

They should be unscrewed carefully, as the screws may fall under the panel. It is better to unscrew them with a screwdriver with a magnetized tip.

We pull the panel slightly towards ourselves and see the green block and wiring harness. Disconnect it by pressing the “tab” and pulling slightly upward. After which the instrument panel will be removed.

Penalty for faulty license plate lighting

The first regulatory act to which you should refer is paragraph 2.3.1 of the Road Traffic Regulations. According to it, traveling to a repair site with a faulty license plate backlight is possible if the driver cannot fix the fault on the spot. This is not an offense, since such a malfunction is not directly indicated as a prerequisite for prohibiting operation.

However, when driving in the dark or in conditions of insufficient visibility, regardless of the reason why the license plate illumination does not light up, the absence of illumination of the state registration plate (state registration plate) clearly turns the rear license plate into “unreadable” according to the interpretation of the law. In this case, the Code of Administrative Offenses, as amended on December 29, 2015, comes into force, stating:

". Article 12.2. Driving a vehicle in violation of the rules for installing state registration plates on it

1. Driving a vehicle with unreadable, non-standard or installed state registration plates in violation of the requirements of the state standard, except for the cases provided for in Part 2 of this article, shall entail a warning or the imposition of an administrative fine in the amount of five hundred rubles. »

Thus, driving with the rear license plate illumination completely inoperative during daylight hours for a traffic police officer can only be grounds for warning the driver about this malfunction, while in the dark this is already a reason for drawing up a protocol on an administrative offense.

Important! We can talk about the license plate being unreadable only if all the license plate illumination lamps are not lit. If one of them is on, the traffic police officer has no right to bring the driver to administrative responsibility

The interpretation of the law also includes severe contamination of license plate lamps.

How to remove the instrument panel, tuning, modifications

Removing the instrument panel on VAZ 2110, 2111 and 2112 cars is not an easy task. But at the same time, it is possible to carry out this repair yourself, if you have the necessary tools at hand, as well as clear instructions.

Regarding the action plan, there are not many detailed guides on the Internet for removing and installing the instrument panel, and all this is due to the fact that the procedure has a number of difficulties and subtleties that not everyone can remember when writing such an article.

However, I will try to make material that will at least 90% help give the overall picture and the main points that should be taken into account when removing the panel on a VAZ 2110-2112. To perform the repair you will need the following tool:

1. Phillips screwdriver, both short and long
2. 10 mm head, preferably deep
3. Ratchet handle or crank
4. Wire cutters or sharp knife
5. Flashlight if necessary

Removing and installing the instrument panel on VAZ 2110, 2111 and 2112

Before you begin this repair, you must do the following:

After this, you can proceed to further actions. We immediately remove and remove all the elements of the panel, such as: the standard clock, the heater control unit, the display unit, as well as the central deflector, and do not forget about the buttons with the radio. As a result, we get approximately the following picture:

Next, using a screwdriver, pry up and remove the plugs at the upper corners of the instrument panel mounting. In reality it looks like this.

On the other side, we do the same, after which, using a socket and an extension, we unscrew the nuts securing the instrument panel in the upper part.

Now let's move on to the remaining attachment points. At the bottom, in the left and right parts of the panel - in the corners, there is also one screw that needs to be unscrewed. The first one is shown below.

The second one is located on the right side of the panel in the same place - at the bottom in the corner. Also, immediately unscrew the self-tapping screw that secures the diagnostic block:

Now we move on to the side fastening points of the frame, which are located in the center on each side - the photo below shows the left side:

On the right everything will be the same. Next we move on to the internal frame fastenings, which are located in the following places. The first one is under the fuse mounting block, to get there we open the cover and look inside the panel:

The second one on the right is visible when the glove compartment lid is open:

Of course, the mounting block will also have to be removed so that it remains intact with the sub-panel wiring.

• We thread it inside with the instrument panel pulled back; you will also have to cut off some of the wiring fastening clamps, for example, in this place, which is shown in the photo:
• Now we are trying to remove the VAZ 2110 panel, moving it to the side on both sides, evenly, without much effort or sudden movements.

In the photo above you can see that the headlight hydraulic corrector tubes were cut off, since in my case they were simply not needed. If you need to save them, do everything carefully and remove them by pulling the control unit out of the instrument panel. Next, we finally remove the panel, of course, after first disconnecting all the wires that will interfere with this.

Installation occurs in the reverse order, connecting all wires and connectors to their places, blocks and switches, as well as other elements that were removed as a result of this procedure.

Installation of Europanel instead of the usual one on VAZ 2110, 2111 and 2112

Many owners who have owned a VAZ 2110 for a long time would like to change the boring panel to a more modern one. In this case, you can install a new type of panel from cars manufactured after 2006, or from the “Bogdan” versions, which are analogues of the tenth family, except that they were assembled in Ukraine.

With such alterations, basically you won’t have to change anything, but it’s worth considering that in this case you need to buy a complete Europanel:

• instrument panel frame assembly with trim
• instrument panel (combination)
• buttons and switches
• heater deflectors
• New heater control unit
• sub-panel wiring
• steering wheel, cover and switches

Only in this case everything becomes without any problems with minimal labor costs.

Block in the engine compartment

The power fuse box is located in the engine compartment under the hood, near the left strut support. To get to it, you need to open the lid by prying the latch.

1 (30 A) - engine control system circuit. If there are problems with the electronic control unit, short circuits or other malfunctions, this fuse may blow out.

2 (30 A) - vehicle on-board circuit. 3 (40 A) - vehicle on-board circuit.

4 (60 A) - generator circuit.

5 (50 A) - electric power steering circuit.

6 (60 A) - generator circuit.

In case of any problems, it is important not to panic, to think soberly and logically. The most important thing is to diagnose and establish the cause of the breakdown.

If you don’t have enough experience or nerves, it’s easier to sign up at the nearest car service center if it has a competent electrician.

I hope this article will help you deal with electrical problems and quickly fix any Priora malfunctions. If you have any experience or information, please leave a comment below, useful information will be added to the article.

Hello guys. Tell me, the backlight of the heater control unit is not on. where to go, where to start? maybe there is a fuse?

Fuses and relays in Lada Priora, electrical diagrams

Lada Priora is another car in the line of new VAZ cars, which is gaining popularity among segments of the population. External similarities with the 10th model attract the attention of young people; the relatively low price is also a reason for purchase for most car enthusiasts. Along with the growth in popularity, the owners of this model are gaining experience in repair and maintenance, which is becoming more and more every year.

If your Priora has electrical problems, do not rush to get upset; first, check the fuses and relays in your Lada Priora. These are the ones that will be discussed in this article.

An exclamation mark is lit on the dashboard: what should the driver do?

Taking into account the fact that there may be several reasons, with the brakes being the most serious, let us dwell on this problem in more detail. If the exclamation mark is on on the panel, the first step is to check the brake fluid level in the reservoir. To do this, just put the car on a level surface, unscrew the tank cap and make sure that the level is between o and “max”. If the level is below the minimum mark, then the exclamation mark on the panel lights up based on a signal from the sensor.

In the case where the driver recently checked the level, and now there has been a sharp decrease, it is important to find the cause of the leakage of fuel fluid from the system. This could be brake hoses, hydraulic clutch, brake cylinders, etc.

It also happens that the indicator lights up while driving over bumps, and then goes out on a smooth road. This means that there is little liquid in the tank, but the level has not yet dropped to a critical level. When the car rocks, the sensor is triggered, while on a flat surface the level of brake fluid is still sufficient for the indicator to go out.

It should be remembered that during operation it is important to periodically monitor the fluid level, use only recommended fluids for topping up, and also promptly change the fluid and bleed the brakes. Let's move on

It may happen that after setting the level, the problem does not disappear. In such a situation, you need to check the fuel oil level sensor itself. The sensor is located in the master cylinder reservoir. To check the sensor, you need to do the following:

Let's move on. It may happen that after setting the level, the problem does not disappear. In such a situation, you need to check the fuel oil level sensor itself. The sensor is located in the master cylinder reservoir. To check the sensor, you need to do the following:

• We turn on the ignition, the exclamation mark lights up, which indicates a low fuel fluid level. Normally, the icon should go out if the level is normal and the sensor is operating normally. If this does not happen, and the liquid level in the tank is normal, then you need to “throw off” the power from the sensor. If the light goes out, the problem is often in the sensor. The float often breaks and lies at the bottom, although there is enough liquid in the tank.
• In the case where the exclamation mark is lit and no power is supplied to the sensor, this situation may indicate problems with the wiring, and the sensor is most likely in working order. The wiring may short out, damage, breaks, etc. may occur.

Dashboard indicator symbols

When starting up, almost all the icons on the dashboard light up - this way the operation of the light bulbs is checked. Some drivers believe that these are messages about malfunctions of some Lada Priora systems.

Block in the engine compartment

The power fuse box is located in the engine compartment under the hood, near the left strut support. To get to it, you need to open the lid by prying the latch.

1 (30 A) - engine control system circuit. If there are problems with the electronic control unit, short circuits or other malfunctions, this fuse may blow out.

2 (30 A) - vehicle on-board circuit. 3 (40 A) - vehicle on-board circuit.

4 (60 A) - generator circuit.

5 (50 A) - electric power steering circuit.

6 (60 A) - generator circuit.

In case of any problems, it is important not to panic, to think soberly and logically. The most important thing is to diagnose and establish the cause of the breakdown.

If you don’t have enough experience or nerves, it’s easier to sign up at the nearest car service center if it has a competent electrician.

I hope this article will help you deal with electrical problems and quickly fix any Priora malfunctions. If you have any experience or information, please leave a comment below, useful information will be added to the article.

Everyone values ​​the time of day! TROUBLE! The instrument lights do not light up. First things first. My speedometer lights probably stopped working half a year ago. Today I decided to do it, changed two light bulbs. I put it in place, turn on the dimensions, and then “Hello.” Only the tachometer backlight is on and that’s it. The rest of the instruments are not illuminated, the arrows also do not light up. The BC monitor is on and working, the arrows are also functioning, the indicator lamps are all on. Only the devices do not light up. I changed the other light bulbs. the same. Zero result.

Maybe someone had something similar? What could it be? Is it really necessary to change the device?

Fuse box in the passenger compartment of VAZ-2170, -2171, -2172

The fuse box in Priora is located at the bottom of the dashboard, on the left side of the steering wheel. To get to it, you need to open the cover, which is held on by three latches. Rotate each locking knob 90 degrees and pull the lid down and it will snap open.

Fuses in the interior mounting block

F1 (25 A) - radiator cooling fan. If your fan does not work, check its motor by applying 12 V directly to it from the battery. If the engine is working properly, then most likely the problem is in the wiring or connectors. Check the serviceability of relay K1.

The fan in the Priora usually turns on at a temperature of 105-110 degrees. Do not allow the engine to overheat, watch the arrow of the temperature sensor.

If the fan runs constantly and does not turn off, check the coolant temperature sensor located on the thermostat. If you remove the connector from the working sensor, the fan should turn on. Check the wiring to this temperature sensor, as well as the contacts of relay K1, move this relay, clean the contacts. If this is the case, replace it with a new relay.

F2 (25 A) - heated rear window. Check together with fuse F11 and relay K2. If the rear window does not fog up, the heating element threads may have broken. Inspect all the threads and if you find a break, seal it with special glue or varnish, which can be bought at car dealerships for 200-300 rubles. Check the connection contacts at the terminals to the heating elements at the edges of the glass, as well as the switch on the dashboard and the wiring from it to the rear window.

F3 (10 A) - high beam, right headlight. F4 (10 A) - high beam, left headlight. If the headlights do not shine on high beam, check the K7 relay and the headlight bulbs. The steering column switch, wiring or connectors may also be faulty.

F5 (10 A) - sound signal.

If the signal does not work when you press the steering wheel button, check relay K8. The signal itself is located under the radiator grille; you can get to it by removing the plastic casing from above. Check it by connecting the voltage to 12 V. If it doesn’t work, try turning the adjusting screw, or replace it with a new one.

F6 (7.5 A) - low beam, left headlight. F7 (7.5 A) - low beam, right headlight. When replacing lamps, be careful; there are separate lamps for the low and high beams, so they can be easily confused. It is better not to install lamps in high-power headlights; the reflectors may melt and the desired effect will not be achieved. Most low beam headlight problems that cannot be corrected by conventional means can be related to the light control module (LCM). The low beam relay is only available in cars equipped with a light sensor, it is located in the place of relay K1; on most cars this relay is not in the mounting block; the low beam circuit goes through the MUS block. It happens that the tracks in the block burn out; if there are problems, it is better to replace it with a new one. If the windshield wipers turn on spontaneously when the low beam is not working correctly, the problem is most likely in the windshield wiper control unit, located in the center of the dashboard, the topmost block, next to the radio, is best reached from the glove compartment, or by hand through the removed console covers at the feet.

F8 (10 A) - alarm signal. If the alarm does not work, also check relay K9.

F9 (25 A) - stove fan.

If your stove does not work in any mode, the problem may be with the stove speed controller or with the engine. Check the stove motor by applying 12 V voltage directly to it. If it does not work, remove it, open the cover and check the condition of the brushes. If the stove does not work only in the first modes, but works in the last mode, most likely you need to replace the heater resistance, located under the hood on the fan scroll.

The price of these resistors is about 200 rubles. Also check that the filter and all pipes are clean and that air flows normally into the stove. If the stove fan squeaks or turns with difficulty, try lubricating it. If the stove turns on and off, check the connectors and contacts in them, they could have melted or oxidized, in this case, replace the connector.

If the car has an air conditioner, the thermal fuse may burn out; it is located near the additional resistance; the fan fuse in the configuration with the air conditioner is located under the hood in the power fuse box.

F10 (7.5 A) - instrument panel, interior lights, brake lights.

If your instrument needles and gauges on the panel stop working, most likely the problem is in the connector that fits it. Check to see if it has fallen out and inspect its contacts. It may also be due to burnout of the tracks on the panel board. In this case, you need to disassemble the panel and inspect it. It can be easily disassembled by unscrewing the screws on top under the trim, on the bottom near the fuse cover and on the side.

If your brake lights do not work, none of them including the additional interior light, most likely the problem is in the switch, which is located at the base of the brake pedal, check and replace it. If some of the brake lights work and some don't, the bulbs are most likely burnt out. To replace the lamp you need to remove the headlight. To prevent the lamps from burning out, replace them with better ones.

F11 (20 A) - heated rear window, windshield wipers. If the heating does not work, see information about F2. If the front wipers do not work, check the tightness of the nuts on the shafts and the operation of the gear motor by removing it and applying 12 V voltage to it. If the motor is faulty, replace it with a new one. Removing the motor is problematic due to the design, so it is better to contact a car service.

The price of a new engine is about 1,800 rubles (if the car is not under warranty). Also check the steering column switch, it may be faulty or its contacts have oxidized.

F12 (10 A) - pin 15 from the devices.

F13 (15 A) - cigarette lighter. If your cigarette lighter does not work, check its contacts and wiring. Typically, problems with the cigarette lighter occur due to a short circuit after using non-standard or low-quality connectors. To replace the cigarette lighter, you need to remove the center console.

F14 (5 A) - left-hand side lamps. F15 (5 A) - right-side lamps. If your headlights stop working and the dashboard backlight does not light up, most likely the problem is in the light control module (LCM), check all the connectors and contacts in them; if the module is faulty, replace it with a new one. If the dashboard lights work, but the dimensions do not, most likely the problem is in the wiring or contacts. Don't forget to check the lamps themselves.

F16 (10 A) - Pin 15 from ABS.

F17 (10 A) - left fog lamp. F18 (10 A) - right fog lamp. If the PTF stops working, the lamps may have burned out, check if there is voltage in their connectors. If there is no voltage there, then in addition to the fuses, there is either wiring, or connectors, or a relay. Also check the power button in the cabin. The lamps in the “foglights” can be replaced by unscrewing the bumper or one side of it, or by unscrewing the fender liners and turning the wheels towards the headlight being replaced, or you need to unscrew the protection from below. You cannot install xenon in the PTF, because there is no tilt angle corrector and there is a high probability of blinding oncoming drivers.

F19 (15 A) - heated seats. If the heated front seats stop working, check the connector under the seat, wiring and the power button.

F20 (5 A) - immobilizer.

The immobilizer blocks the ignition circuit and the operation of the fuel pump. If the immobilizer does not see or loses the key, and also does not work correctly, try replacing the battery in the key. The electrical package control unit, which is located in the center of the dashboard, in the area of ​​the radio, the second unit from the top with a black housing, could have failed. If you have lost your key and want to use a new one, you will need to register it in the immobilizer firmware.

If you disable the immobilizer, a light with a key symbol will light up on the panel, this means that it is looking for a key.

F21 (7.5 A) - rear fog lamp.

F22-30 - backup fuses.

F31 (30 A) - electrical package control unit.

Relay in the interior mounting block

K1 – radiator cooling fan relay. See information about F1.

K2 – relay for turning on the heated rear window. See information about F2.

K3 – starter activation relay. If the starter does not turn when you turn the key, first check the battery voltage and the contacts of its terminals, if necessary, clean them from oxidation and tighten them firmly. Charge the dead battery or replace it with a new one. The common ground contact in the engine compartment or the contact on the solenoid relay may also disappear; check whether the nuts are securely fastened and whether they hold the wire terminals well.

You can check the starter by closing its contacts directly with a screwdriver when the gearbox is in neutral gear or by applying a plus from the battery to one of the retractor contacts. If it turns, it means the problem is in the wiring or the ignition switch. If not, most likely the starter itself or the retractor is faulty.

Another reason may be the lack of contacts in the ignition switch. Also check the contact group, wires and connectors.

K4 – additional relay (ignition relay).

K5 – backup relay.

K6 – front wiper and washer relay. See information about F11. If the washer does not work, in the cold season, check the washer system pipes for frozen liquid and blockages, and also inspect the nozzles. Check the pump and its contacts by applying 12 V voltage to it; the pump is attached to the reservoir with windshield washer fluid. If the pump fails, replace it with a new one.

K7 – headlight high beam relay. See information about F3, F4.

K8 – horn relay. See information about F5.

K9 – alarm relay. Check together with fuse F8.

K10, K11, K12 – backup relays.

How to change instrument lighting on a Priora

Replacing the backlight of the Lada Priora instrument panel

Task: replace the dashboard backlight in Lada Priora

We remove the dashboard of the Lada Priora. Let's disassemble it, everything is simple (4 screws and everything else is secured with latches). Another important thing is to carefully remove the hands and not damage them. Peel off the lining (overlay with numbers) and on the back side of this lining we begin to erase the green coating. I washed with ear sticks and rubbing alcohol (solvent is not recommended).

Next, carefully remove the LCD screen. We take out the green filter, erase the green coating of the filter and put everything back

Next, we change 5 light bulbs to white LEDs (you can also install red or blue LEDs, whichever backlight you prefer). I bought white LEDs together with a base at a radio store.

Let's put everything back together in reverse order.

The photo shows that it shines brightly, but in real life it is much worse. After driving around, some diodes began to blink, apparently there was a bad contact, and I decided to change the backlight a little.

I bought 1 meter of LED strip and a soldering iron with a thin tip.

Let's begin. We take the tape and cut strips, 3 diodes in each, and solder the wiring to them. I took solid copper wire.

Next, glue these strips in the same way as shown in the photo. In some places it is necessary to drill holes for the wires.

Let's check this whole thing. To test the LEDs, I bought a 9 volt Krona battery. All diodes light up

We take the board and connect it to the car, turn on the dimensions and use the control light to find the plus and minus of the backlight. And solder the wiring to them.

Then we assemble everything and twist and insulate all the wires.

I wanted blue arrows. I bought blue fluorescent paint at an art salon. I wiped off the red coating on the hands and painted it.

It shines very brightly. You set the backlight control to minimum and everything is fine, it doesn’t dazzle. But still I decided to tint it with 20Koy.

Here is the final version of the work done. I spent 2 evenings on this matter and was pleased with the result. Now it shines evenly and brightly.

Result: work on replacing the dashboard backlight of the Lada Priora has been completed
