Tidy 2115: description and purpose of buttons and knobs

If everything is simple with the levers on the steering rack, there is a headlight position switch and a turn signal switch on the left. Buttons are more difficult.

Lada 2115: the oil light on the center panel is on

If an icon in the shape of a watering can appears on the console, this indicates that there are problems in the engine lubrication system. This is caused by a drop in the oil level in the crankcase or a pump malfunction. If the engine is old, the problem may be caused by clogged oil lines.

What does the exclamation mark on the Lada 2115 tidy mean?

On the "tag" the symbol is used in only one form - a red indicator in a circle. The icon indicates a malfunction in the vehicle's brake system. If this symbol lights up while driving, stop and find the cause of the breakdown. Usually it is enough to add fluid to the expansion tank or replace worn pads.

The battery light on the dash is on 2115

A red battery icon indicates that the battery is not charging properly. A complete diagnosis of on-board systems associated with the generator set and its wiring is required.

Identification of buttons

It is also important to know the designation of the buttons on the VAZ 2114 panel. On the instrument cluster on the right side there is a button (11), with which the time and temperature on the digital indicator are switched, and when pressed for 5 seconds or more, the current mileage is reset, if pressed this button on a stationary car.

In the central part of the dashboard are located in a row:

Double headlight switch. Button 1 turns on the dimensions, button 2 turns on the low beam;

Buttons on VAZ 2114

Key switch block. The first 1 turns on the front fog lights, the second 2 turns on the rear fog lights and the third 3 turns on the heated rear window.

Description of faults

Tidy 2115 stopped working

Occurs after power surges or moisture getting under the panel (condensation). If the device has completely failed, but other elements of the car are working, check the fuse and wiring of the element.

When only part of the panel does not show or the board lighting has failed, perform diagnostics of the illuminators and their contact groups.

Tidy does not light up

If the backlight does not function, as well as the dimensions on the left side of the car, check the corresponding fuse. When the insert is working properly, you will need to diagnose the mounting block for voltage.

Panel 2115 blinks

It happens when the device does not work correctly. The backlight blinks and the elements constantly jump. There are problems with contacts here. The pads may become loose or oxidized.

The solution to the problem is to clean the contacts from oxidation and tighten/replace the pads.

The temperature sensor on the device 2115 does not work

The solution lies in diagnosing the system and correcting breakdowns.

The arrows on the dashboard 2115 do not work

The fault lies with the blown fuse F3. Before replacing it, be sure to diagnose the wiring and eliminate problems and possible short circuits.

One or more light bulbs do not light up

In this case, there can be two situations:

• The backlight of the VAZ 2114 instrument panel does not light up;
• One or more warning lamps are not working.

Let's consider the first variant of malfunctions, when the backlight of the VAZ 2114 instrument panel does not work. You must begin checking the functionality of the backlight by checking the serviceability of the fuse in this circuit. This only applies when all the backlights are off.

The fuse box on this model, as well as on the VAZ 2113 and VAZ 2115, is located in the engine compartment on the driver's side. You need to remove its cover and find the fuse responsible for the backlight, this is F10. It is designed for a current of 7.5 A. If it burns out, replace it with a new one and check the operation of the backlight paws.

Further events can develop as follows: either everything works or it doesn’t. If the instrument panel backlight works, the test ends here, otherwise it is necessary to continue troubleshooting. It may be due to poor contact of the connectors or an open circuit in the power supply of the backlight lamps.

To find and eliminate these problems, you need to remember the basic concepts of the laws of electrical engineering, and have a car LED electrical circuit tester, tester or voltmeter. If there is neither one nor the other, then it is better to seek help from an auto electrician.

The situation is much simpler when one or more, but not all, backlights are off. Burnt out light bulbs are simply replaced with known good ones. From the practice of auto electricians, we can conclude that in most cases a fuse or light bulb blows. It rarely comes to troubleshooting using instruments, but sometimes it happens. You should be aware that if a replacement (new) fuse blows repeatedly, you should look for a short circuit in the electrical circuit.

In the second case, they do approximately the same, but take into account that there are no fuses for each indicator lamp. They try to replace the light bulb with a new one, if it doesn’t light up again, then the contacts need to be checked. As a rule, this is enough to troubleshoot problems. Otherwise, it is better to ask a specialist for help, because the sensor that works in conjunction with this warning lamp may be the culprit.

Dashboard lamps

How much does a shield cost?

In 2022, you can find a tidy device from 1000 rubles. If you need to purchase a complete module with all the plastic and instruments, the purchase will cost approximately 8-10 thousand.

The standard dashboard of the Lada 2115 is informative and has a discreet design. The module is easy to read and intuitive even for novice drivers.

Error codes VAZ 2115

The VAZ company develops on-board computers so that fault codes for Lada 2115 and other models can be read in two ways at once.

The self-diagnosis procedure involves collecting and decoding errors through the on-board display. This method is suitable for quick repairs and troubleshooting.

From 2005 to 2022, more accurate diagnostics became possible. A specially designed OBD2 port allows you to connect equipment to the car. An external computer shows problems down to every detail.

Decoding fault codes VAZ 2115 8 valves

Depending on the type of device, certain symbols and numbers are displayed on the dashboard, indicating the presence of an error. In self-diagnosis mode, the data is reflected on the instrument panel in the square of the on-board display. A one or two-digit number indicating the problem is indicated here.

If diagnostics are performed by a third-party device, error codes are displayed on the computer display and are represented by an alphanumeric code consisting of 5 characters, where the first indicates the area of ​​failure. The second sign indicates the factory code, the third specifies the problem circuit. The last 2 digits indicate the problem itself.

The complete table of faults for the VAZ 2115 contains more than a thousand names and encodings. The following are only the most common problems.

Error 01

The microprocessor has failed. There is a firmware glitch. Repair consists of replacing or reconfiguring the module.

Error code 2

The fuel level sensor in the tank is damaged or stuck. Disassemble the system and inspect the sensor for damage.

Fault 3

It is a combination of errors No. 2 and 1. Troubleshooting is indicated above.

Breakdown 4

Excessively high voltage in the network. The reason lies in a short circuit in the line.

Error 8: Lada 2115 8 valves

The problem arises when the car has an injector. The causes and elimination of the malfunction are completely opposite to point number 4. Here we are talking about a critical voltage drop in the on-board network, which is caused by battery failure or damage to the generator set.

Error 10

This means that when the engine is under high load, a lean fuel mixture enters the engine. The behavior causes a malfunction of the injector or throttle valve.

Breakdown 11

Indicates the presence of two or more problems at the same time. The number is obtained by adding the codes 8 and 3.

Fault 12

The check engine light is damaged or there is a problem with its wiring. It can be eliminated by studying the entire highway followed by repairs.

Error 14

The coolant temperature sensor is faulty or not working correctly. The situation can only be corrected by completely replacing the part - the sensor cannot be repaired.

What is a dashboard?

The concept of “dashboard” is interpreted in different ways. Some argue that this is just an electronic panel with arrows, icons and scales. Others consider all the instruments on the dashboard to be a panel, on which a common cover is attached - the instrument panel, wiper arms, heater, air conditioner, ashtray, cup holder. The second option is the definition of “instrument cluster”.

The phrase “dashboard” implies a group of instruments that are combined by a common design.

The above designations are divided into control and measuring instruments and warning lamps. On the VAZ 2115, control and measuring devices are those devices that are indicated with scales and arrows. But in the simplified lexicon of motorists, the instrument panel (console) is usually called the entire part of the dashboard, which is covered by a cover on top and where any information is displayed, there are push-button and lever controls.

In this case, the main instrument panel refers to the instrument panel, which is located behind the steering wheel. The middle part, located above the gearshift lever, is in this case called the center console. And the levers and buttons for adjusting the lighting, cleaning the glass, and regulating the temperature are the controls. Everything is assembled - a VAZ 2115 instrument cluster.

The main instrument panel on the VAZ 2115 became one of the first VAZ panels of the modern VDO model.

How to reset errors on a 2115 injector yourself, without a computer

To reset dashboard codes, drivers use 2 methods.

In the first option, faults can be eliminated by disconnecting the power terminals from the battery. The circuit is opened for 15 minutes and put back together. After this, the bookmaker will restart and information about problems will be updated.

You can also perform a reset using third-party equipment, but this is relevant for service stations and service stations.

It’s easy to count Lada 2115 errors yourself. The disadvantage of the procedure is the impossibility of accurately determining the exact location of the breakdown. For detailed diagnostics, it is recommended to use special equipment.

Diagnostics

There are two ways to set error codes for VAZ 2114 injector 8 valves. However, each method has unique advantages and disadvantages.

Self-diagnosis of VAZ 2114: error codes and their interpretation

The self-diagnosis method does not require the driver to have complex instruments or additional units. To complete the procedure, the car itself is enough.

The standard sequence of actions looks like this.

If the sequence of actions is performed correctly, all indicators will light up and the display will show a two-digit fault code.

Note!

A failure signal may be a lack of response from the indicator. In this case, it is necessary to check the circuit coming from the device.

The most common error codes for the VAZ 2114 panel, occurring in 90% of cases:
In some cases, errors may overlap each other if the breakdown is similar. For example, if errors 1 and 4 intersect, the panel will indicate "5".

It is important to know that after viewing, VAZ 2114/2115 error codes do not disappear on their own after repairs are performed. They need to be forced reset. To complete the work you will need a simple sequence of actions:

This also needs to be done if you are planning a trip to a service station. Having discovered the instructions from the on-board computer, the technicians will correct these problems, which will definitely be more expensive.

The disadvantages of an independent procedure include the low accuracy of the data. On-board diagnostics only show the general direction vector where the fault should be looked for.

Check using diagnostic equipment

You can identify error codes for VAZ 2115 and 2114 using a laptop with a special program. The tool is connected to the vehicle's test socket through a set of adapters. The wizard configures the software, and after diagnostics, one or more faults will be displayed on the computer screen in the form of a five-digit code.

The first part is the letter:

The second part is a single digit:

The next element is the breakdown group indicator:

The final two numbers point directly to the problem itself.

Brief instructions for operating the on-board computer

There is no need to memorize all kinds of error codes. It’s best to simply find the designations of all the errors on the Internet, where, by the way, they are freely available, print them out on a piece of paper and carry them with you in the car all the time. And when you see a particular error code on the computer information board, it won’t take you much time to understand what exactly it means, you just need to look at the previously printed list.

By the way, it often happens that the on-board computer issues a danger signal for absolutely no reason. The reason for this may be the on-board computer processor or some sensor that is not working correctly. Remember, no one is immune from electronic errors. Nevertheless, in the vast majority of cases, the VAZ-2115 on-board computer works quite correctly.

We present to your attention the most common error codes with their interpretation:

If the numbers 4, 6 or 8 appear on the car’s on-board computer while driving, you should immediately stop, fix the problem and only then continue driving. But after this you will need to reboot the processor. The error can be reset by simply holding down the daily mileage key for a few seconds.

Operating principle of the on-board computer

Cars such as the VAZ-2109 were equipped with devices that acted as routers. Let us remember that these were carburetor cars. But the VAZ-2114 and 2115 began to be equipped with injection power plants, which required the use of a completely different type of device.

Therefore, the main functions of the on-board computer on these cars are diagnostics, as well as control of the operation of almost all vehicle systems.

The principle of operation of the on-board computer on the VAZ-2115 is as follows:
