Replacing the ignition switch and contact group on a VAZ 2108 VAZ 2109 VAZ 21099

Welcome! The ignition switch breaks quite rarely, but it still happens. After a lock breaks, it of course needs to be replaced with a new one, but how to do this, you ask? Some people still know the answer to this question, but some do not. For those who don’t know, we have prepared this article, which will describe in detail the process of replacing the ignition switch. And at the end of this article you will find a video clip that will describe in detail the process of replacing this lock. Note! To replace the ignition switch, you will need the following tools: First, you will need screwdrivers. When do you need to change the ignition switch and contact group? It must be replaced if it breaks, as well as if the key is lost, and even if the cylinder in the lock stops turning and is stuck in one place. The contact group must be replaced if it is deformed, and even if, after turning the key in the lock, the car’s engine stops starting.

Note! Before you immediately say that the contact group of the lock is to blame for everything, first check the contacts of its wire blocks for functionality. (How to check the contacts of the contact group, see below in the section: “Checking the contacts of the wire block”)

How to replace the ignition switch, check the contact group and replace it on a VAZ 2108-VAZ 21099?

Replacing the ignition switch:

Removal: 1) Starting with “The battery is a rechargeable battery,” unscrew the nut that holds the “-” terminal on the battery and then remove the terminal.

2) Then remove the steering column cover and both steering column switches.

Further, for clarity, the operation will be shown with the steering wheel removed, but you can still remove the ignition switch without removing the steering wheel.

3) Next, insert if the lock allows it, then insert the ignition key into it and put it in position “0”.

Replacing the ignition switch and contact group on a VAZ 2108, VAZ 2109, VAZ 21099

Welcome! The ignition interlock breaks quite rarely, but it still happens. After breaking the lock, it must be replaced with a new one, but how do you ask? Some people still know the answer to this question, and some don't. For the ignorant people, we have simply prepared this article, which describes in detail the process of replacing the ignition. And at the end of this article you will find a video clip that details the progress of replacing this lock.

How to replace the ignition switch of a VAZ-2109

One of the main components of the VAZ-2109 can be called the ignition switch; the successful start of the car and the operation of elements dependent on the electrical network depend on it. Usually it works for a long time, trouble-free, and breaks down extremely rarely, but if this happens, then replacement is inevitable. Some car enthusiasts have driven half their lives and never encountered this problem, others are less fortunate. In any case, in order to confidently drive on the roads, it is advisable to know how to replace this element of the car yourself.

“Classics”, as well as the “Ninth” family

Fiat engineers, when developing the ignition switch for their 124 model, used two supply lines (“30” and “30/1”). The ignition line was the only one.

Another ignition circuit containing contact “15/2” was added during the transition to the “2109” family. It, in turn, is switched using a relay. In different families, only the diagram differs, but not the “behavior” of the car when the key is installed opposite the marks:

Position 0: everything is off;
Label 1: ignition and engine operation;
Mark 2: starting the starter;
Label 3: “Parking” mode.

To turn off the engine, turn the key to position “0”. The spark plugs lose spark and the engine stops.

The ignition switch module, if we talk about the “classic family”, is equipped with 5 terminals (see Fig. 2). Starting from the “2109” family, this solution is not used. Several wires come out of the lock cylinder and are connected to a remote connector.

Pinout of the ignition switch VAZ-2101 - VAZ-2107

The ignition switch on these cars is located to the left of the steering column. It is fixed directly to it using two fixing bolts. The entire mechanism of the device, except for the upper part in which the keyhole is located, is hidden by a plastic casing.

On the visible part of the ignition switch housing, special marks are applied in a certain order, allowing inexperienced drivers to navigate the lock activation mode when the key is in the hole:

“ ” – a mark indicating that all systems, devices and instruments that are turned on using the lock are turned off (this does not include the cigarette lighter, interior lighting, brake light, and in some cases the radio);
“ I ” is a mark informing that the vehicle’s on-board network is powered from the battery. In this position, the key is fixed independently, and electricity is supplied to the ignition system, to the electric motors of the heater and windshield washer, instrumentation, headlights and light signaling;
“ II ” – engine start mark. It indicates that voltage is applied to the starter. The key does not lock in this position. If you release it, it will return to the "I" position. This is done so as not to subject the starter to unnecessary loads;
“ III ” – parking mark. If you remove the key from the ignition in this position, the steering column will be locked with a latch. It can only be unlocked by inserting the key back and turning it to position “0” or “I”.

The ignition switch has five contacts and, accordingly, five terminals, which are responsible for supplying voltage to the desired unit. All of them are numbered for convenience. Each pin corresponds to a wire of a certain color:

“50” – output responsible for supplying current to the starter (red or purple wire);
“15” – terminal through which voltage is supplied to the ignition system, to the electric motors of the heater, washer, and instrument panel (double blue wire with a black stripe);
“30” and “30/1” – constant “plus” (pink and brown wires, respectively);
“INT” – external lighting and light signaling (double black wire).

Video “Replacing ZZ”

This video demonstrates the repair of the ignition switch of a VAZ 2109 (the author of the video is Vitaly Rau).

Schematic electrical diagrams, connecting devices and pinouts of connectors

The ignition switch in cars of the VAZ family fails from time to time due to weakening of the contact posts or burning of the contacts inside it. It also happens that the cams of a plastic roller are produced. You can disassemble the lock and clean it, but it’s better to just replace it with a new one, considering that it costs pennies compared to imported locks.

But if connecting the wires together did not result in the starter operating (or it did not turn on the first time), check the solenoid relay on the starter. The contact spots on it may also burn out, which will prevent the circuit from closing normally. Alternatively, you can use a screwdriver to short-circuit the two large terminals on the solenoid relay (before doing this, put the car in neutral and use the handbrake). When closed, the starter should begin to spin vigorously. If this happens, remove and change the solenoid relay. If the starter rotates “sluggishly” when it closes, you will have to remove it and check the condition of the brushes.

All operations are performed with your own hands, without the help of car service specialists. Moreover, the price of an ignition switch on a VAZ2106 is up to 100 rubles. To replace it, you will need to know the pinout of the wires coming from it, for which the editors of the site 2 Schemes.ru have prepared a large reference material.

The ignition switch is designed not only to start the engine - it performs several functions at once:

supplies voltage to the vehicle’s on-board network, closing the circuits of the ignition system, lighting, sound alarm, additional devices and instruments;
at the driver’s command, turns on the starter to start the power plant and turns it off;
turns off the power to the on-board circuit, preserving the battery charge;
protects the car from theft by fixing the steering shaft.

What is

First, let's look at the structure of the castle. Let's find out what it looks like, what it consists of, what its operating principle is, and so on:

As mentioned, the ignition switch is a very important element of the VAZ 2109 car, because almost all available equipment is connected to it.

Note. Although there are components that do not depend on the lock in any way. Here they are: license plate lights, brake lights, parking lights, hazard lights, interior lights and lights on the dashboard.

There are different types of ignition switches: new or old type. The first version without a relay has three positions and a short key, the second with a relay has four positions and a long key.

VAZ 2109 ignition switch malfunction

Purpose and device

The main purpose of the lock was initially to protect the car from theft, however:

Today, as can be seen from practice, in order to start and steal a car, car thieves do not necessarily need to have a key or a duplicate of it
To put it more clearly, the protection from the castle used to justify itself, but today it is “so-so”
Advanced car thieves, equipped with modern technologies and devices, are able to hack the electronic protection of the most modern anti-theft systems in just a few seconds.
And on the VAZ 2109, the lock cylinder or the VAZ 2109 lock itself, or its domestic analogue can generally be called entertainment for beginners
In fact, the ignition switch is an ordinary switch that, when you turn the key, opens or closes a certain group of contacts
The appearance of a malfunction in the ignition switch increases the likelihood of vehicle theft several times, in addition, it creates great trouble for you and, according to the law of meanness, at a completely inappropriate moment for this
The design of any ignition switch is similar; it consists of a lock and its contact group
And the contact group consists of two separate plates, fixed and movable
The movable plate moves when the key is turned in the lock and the contacts are closed in the required sequence
Already now, switches that have the same design and order of contact closure are successfully used on all domestic cars

Reasons for replacement

As a rule, replacement of VAZ 2109 lock cylinders is carried out in the following cases:

When they tried to steal a car and the lock cylinder was damaged in the process
If the owner of the car has lost his keys
Breakage of the larva during operation

The car engine may not start due to poor contact. It’s not at all difficult to check this; to do this, it’s enough to have an ohmmeter on hand, or a multitester with an ohmmeter function and five minutes of time:

Disconnect the “-” terminal from the battery
Remove the lower casing from the steering column

Removed the casing and opened the contacts

Disconnect the contacts and check the resistance with an ohmmeter
Serviceable contacts should have minimal (zero) resistance
Otherwise, you need to replace either the contact group or the entire lock

We measure the contact resistance using an ohmmeter

Preparation

At the preparation stage, you will need to collect the necessary tools near you, which will be useful in the process of dismantling and installing a new ignition switch. You will also have to remove the steering cover and steering column shifters. Doing this is quite difficult, but we will tell you step by step about all the nuances of these preparatory activities. So you can easily figure out for yourself how to remove the ignition switch on a VAZ 2114.

Tools you will need:

Phillips strong screwdriver;
Open-end wrench 10 millimeters;
Chisel;
Hammer;
Pliers or pliers;
New ignition switch assembly;
Lock mounting screws (4 pieces).

Now let's move on to the casing and switches. For more convenient work, many advise removing the steering column switches and the steering wheel itself. Dismantling the casing is performed in the following sequence:

Disconnect the negative cable from the battery. Nobody has yet canceled the requirements for personal safety and protection against electric shocks;
Unscrew the three screws securing the two parts of the casing. A screwdriver is useful for this;
Unscrew the screw that connects the housing to the connector of the steering column switches;
Remove the two screws that hold the lower housing to the steering column;
The lever that fixes the column at the corner leads down;
The steering wheel also goes down;
The lower casing is then removed;
The power supply from the emergency lights must be disconnected;
Now you can remove the top casing;
To dismantle the steering column switches, you need to act one by one;
Simultaneously press both latches and thereby remove the elements from their seats;
Disconnect them from the power supply.

Device

On the VAZ-2109 you can find the ignition of a new, as well as an old model. Older models have 4 positions, a long key and a relay. The new ones have 3 positions and a short key, but there is no relay at all. The ignition switch in the VAZ-2109, as well as in other cars, is designed to perform two functions: to lock the steering column (mechanical) and to close contacts when turning the key (electrical).

The electrical part works depending on the turn of the key:

car de-energized – 0;
voltage supplied to the entire electrical network – 1;
supplying current only to the starter – 2;
turning on emergency lighting.

Exactly three switched contacts

One line through which current is supplied, and only one ignition circuit - this solution is typical for all VAZ cars, if we talk about the “2110”, “2170” and later families. Even in Grants, produced since 2012, the additional ignition circuit did not appear. In general, with the transition to the “Ten” family, three “significant” terminals of the lock remained:

Contact "30";
Terminal “15” (can be designated as “15/1”);
Terminal "50".

The ignition switch circuit looks trivial, even if we talk about the Lada 2110.

The Tens connector has 8 terminals. And in Priora, as well as in Grant and Kalina, this number is reduced to three (Fig. 2).

The lock connector of all VAZ models, starting from “2170”, is equipped with only three contact terminals. And the additional connector, which is equipped with a pair of terminals, is connected to the immobilizer in these cars.

The “3” mark has disappeared from the “Tens” lock cylinder. And until now, VAZ produces just such locks, where the key can be installed in one of the following positions:

"Turned off";
"Ignition";
"Start".

The presence of the “Parking” mode, as you can see, is not provided here.

Replacing the lock cylinder itself or the contact group

Replacing the VAZ 2109 lock cylinders requires the following tools:

New cylinder complete with keys
Thin clock screwdriver
Phillips screwdriver
Fine drill
Chisels
Hammer
Pliers

In the event of any breakdown, it is not necessary to replace the entire lock; if the cause of the malfunction lies in replaceable parts, then a partial repair of the lock is performed and replacing the lock cylinders on the VAZ 2109 makes sense when the key stops rotating freely in the keyhole. Another option for partial repair is to replace the contact group; for this, a minimum of tools and a little understanding of the device are enough. Our instructions will help you understand the device:

Nothing and no one forbids you to change the entire lock every time, and even go to a service station if you are satisfied with the price
After removing the casing, access to the switch lock opens
The lock cylinder can, in principle, be removed at this stage
Therefore, we pull out the side pin that holds it in the lock
This can be easily done with a thin screwdriver (clockwise) while tapping it with a small hammer
If the pin cannot be pulled out in this way, then try to drill out the cylinder carefully using a thin drill
If it is more convenient for you to remove it first, remove the ignition switch before proceeding to replace the cylinder, to do this you need to unscrew the bolts securing the ignition switch to the steering column
This must be done using a hammer and chisel, as these bolts have sheared heads.
Use a chisel to loosen them slightly, and then unscrew them with pliers, as in the photo below

Loosen the bolts securing the lock to the steering column

Now we remove the bracket and the lock itself from the column, be sure to disconnect its electrical connector
We unscrew the screw securing the ignition relay and remove it from under the panel
Disconnect the connector
Disconnect the “mass” wire
Using a Phillips screwdriver, unscrew the screw
Then release the latch and remove the cover, then the contact group
So we pulled the switch
We remove the cylinder with our own hands and the ignition switch, as already described above
We are replacing it
We check the operation of the lock with a new cylinder installed, to do this we turn the ignition key
After installation, do not forget to check the correct operation of the locking mechanism, our steering shaft
When the mechanism does not work when turning the steering wheel fully, you need to adjust the location of the lock on the steering column
Only after completing the adjustment of the location and checking the functionality of our locking mechanism, you can tighten the bolts until the heads come off completely, use a “10” spanner for this purpose

Repair and replacement

Typically, the lock can be repaired. If this fails, you will have to completely replace it (see Replacing the VAZ ignition switch on your own). Repairing a lock in most cases comes down to replacing the cylinder or contact group. If after this the problem has not been resolved or it is possible to change the entire lock, then it is better to do the latter.

Larva and its replacement

So, we do the following:

Remove the steering column cover and unscrew the fastening bolts that tighten the ignition switch clamp.

Note. The bolts have sheared heads and then you will have to use a hammer and chisel. The bolts are first loosened by blows with a chisel, and then unscrewed with pliers.

We separate the two parts of the clamp so that they disengage;
The larva can be changed already at this stage of the operation;
We take out the side pin that holds the cylinder in the lock.

Advice. The cylinder can be easily removed with a thin screwdriver, for example, from a watch. At the same time, you need to tap the lock with a hammer.

If you cannot pull out the cylinder after the side pin has been removed, you can try to drill out the cylinder using a thin drill;
If again it was not possible to remove the cylinder, then it is recommended to finally remove the lock;
Remove the wire plugs.

Note. One of the plugs (the one with the larger connector) is located under the dashboard. To remove it, you need to put your hand under the panel.

If the ignition switch has a relay, then take it out from under the panel;
Disconnect the connector;
We also remove the ground wire;
Remove the cover by pressing the latch, and then the contact group;
Now it will be much easier to remove the larva;
We replace it with a new one;
We check the work on site before putting everything back into place. We turn the key inside the lock - all the processes described above should work.

Note. Don't forget to also check that the steering wheel lock works. If the steering shaft does not lock when the steering wheel is turned completely, we adjust the correct location of the lock on the column.

After a thorough check, making sure that everything works correctly, tighten the bolts until the heads come off. It is advisable to use the key at “10”.

Typical faults

VAZ 2109 ignition switch

The lock belongs to the car's ignition system. Let us note right away that if problems are observed, you can fix them yourself, because, as a rule, the “nine” is equipped with an outdated ignition system that does not require diagnostics and repair at a service station.

How to make sure there is a problem

Below is a tip on how to make sure that the ignition switch is really not working:

We insert the ignition key and turn it to a certain position. A short circuit in the circuit must necessarily occur. We look at the diagram: if the key is in position “1”, is the external lighting or control devices working;
It is recommended to check at all positions of the lock. If deviations from the norm are observed, there is a problem with the lock;
You can also check the functionality of the ignition switch in the following way: turn the steering wheel, which should not be blocked. The lock on a working steering wheel should only work when the key is turned a second time from position “1” to position “2”;

VAZ 2109 ignition switch malfunction

You can reliably check whether the lock works like this: take an ordinary portable lamp and connect one end to ground, the other to the lock. We turn on the ignition - if the light is on normally, then the lock is in order. If the light glows dimly or does not light at all, the lock is faulty.

Steering lock testing

If you don't check the steering lock, you may encounter certain problems in the future. Therefore, do not waste your time on this event. It consists of removing the key from the ignition and turning the steering wheel at a slight angle.

If there is no lock, you will need to slightly adjust the position of the lock. Make sure it fits into the groove located on the steering shaft.
If the locking is effective, you will only need to tighten the four installed breakaway bolts until they stop. Twist until the heads break.

When the lock installation is completed and the test has passed, do not forget to connect the device to power and start the engine. If it starts, all systems dependent on the ignition switch are working, you can fully begin reassembly. Follow the reverse instructions for removing the casing and steering column switches. It would not be amiss to check the condition of certain nodes along the way. It is quite possible that some of them also need replacement or a little preventive maintenance.

Malfunctions

Considering that the ignition switch is designed to perform two functions, all breakdowns are divided into mechanical and electrical. Mechanical malfunctions include jamming of the cylinder in one of the positions when it is impossible to turn the key. Contact group, which is time to change when the car engine does not start when you turn the key or deformation has occurred.

Electrical faults can occur in any position of the key, as they are associated with a violation of the integrity of the electrical network.

In a situation where there is no contact, all components of the system do not function. If there is a contact in the wrong place, a short circuit and overheating will occur, which will lead to the need to install a new lock.

Replacing the ignition switch and contact group on a VAZ 2108, VAZ 2109, VAZ 21099

Welcome! The ignition switch breaks quite rarely, but it still happens. After a lock breaks, it of course needs to be replaced with a new one, but how to do this, you ask? Some people still know the answer to this question, but some do not. For those who don’t know, we have prepared this article, which will describe in detail the process of replacing the ignition switch. And at the end of this article you will find a video clip that will describe in detail the process of replacing this lock.

Note! To replace the ignition switch, you will need the following tools: First, you will need screwdrivers, and you will also need a drill, a small hammer, pliers, and you will definitely need to stock up on a chisel!

When do you need to change the ignition switch and contact group? It must be replaced if it breaks, as well as if the key is lost, and even if the cylinder in the lock stops turning and is stuck in one place. The contact group must be replaced if it is deformed, and even if, after turning the key in the lock, the car’s engine stops starting.

Note! Before you immediately say that the contact group of the lock is to blame for everything, first check the contacts of its wire blocks for functionality. (How to check the contacts of the contact group, see below in the section: “Checking the contacts of the wire block”)

Removing a faulty lock

Unscrewing the ignition switch bolts with a chisel

In practice, replacing the ignition switch on a VAZ 2114 will be impossible until you get rid of the old one. This is not difficult to do, but you will have to spend some time on your car.

Once you have gained access to the ignition switch, or rather its housing, you will notice that the lock is attached to the steering column with four bolts. The problem is that they don't have heads.
This phenomenon is part of the “unique” factory anti-theft system manufactured by AvtoVAZ. In fact, such a system makes it somewhat more difficult for criminals who do not have a key to start the engine. So don't scold them too much.
These bolts are loosened with a chisel and hammer, and their removal is done using pliers.
Next, remove the bracket from the column;
Be sure to unplug the power supply. In general, the wiring diagram for the VAZ 2114 ignition switch is simple if you buy the lock assembled. You don't have to solder anything or figure out which wire goes where. Everything is assembled into a block, so all that remains is to insert it into the appropriate connector. That's all.
By disconnecting the power supply, you can now finally get rid of the failed ignition switch.

Changing the contact group

Exploded view of the lock

From a cost point of view, replacing one contact group is the least expensive:

All our actions are repeated in principle, as in the case described above with removing the lock, you will have to remove the casing, and so on
To avoid the common nuisance associated with mixing up contacts, it is recommended to number them (or otherwise mark them) before disconnecting them.
This measure will save your nerves and time
Some models of locks have a locking ring in their contact group, and here we need an awl to remove it
It’s important not to forget to put it back in place later.
Then everything is assembled back and screwed to the steering column

That's all, all that remains is to finish watching the video and calmly change any part of the lock.

The ignition switch of the VAZ 2109 is faulty.

The most common problem with the ignition lock is its working out and jamming. If these symptoms occur, you should immediately replace the entire ignition switch, because in case of jamming, you can simply burn the starter and then the repair will cost you the cost of the starter. Another common problem is the failure of the contact group. In this case, several devices fail at once. For example, my low beam headlights, heater, cigarette lighter, and rear window heater immediately stopped working. Replacing the contact group with a new one, everything worked immediately.

How to replace the ignition switch, check the contact group and replace it on a VAZ 2108-VAZ 21099?

Replacing the ignition switch:

Removal: 1) Starting with “The battery is a rechargeable battery,” unscrew the nut that holds the “-” terminal on the battery and then remove the terminal. (How to remove the negative terminal from the battery, see the article about “Replacing the battery on a VAZ”, in the “first” paragraph)

2) Then remove the steering column cover and both steering column switches. (How to remove the casing and both switches, see the article: “Replacing under-steering switches”)

Further, for clarity, the operation will be shown with the steering wheel removed, but you can still remove the ignition switch without removing the steering wheel.

3) Next, insert if the lock allows it, then insert the ignition key into it and put it in position “0”.

Note! The key must be installed in this position only to disable the anti-theft device!

4) Now remove the four bolts that secure the ignition switch. If you have these bolts with a cut off head, then knock them down with a hammer and chisel. (Be sure to read the “Important!” paragraph)

Note! If that doesn’t work, then try drilling out all four bolts, but just do it carefully without damaging anything!

5) Once the bolts are loosened, use pliers to remove them from the hole.

6) Next, remove the bracket on the left side, and the ignition switch on the right.

7) Now disconnect the wire block from the electrical connector.

And finally, crawl under the dashboard, and there, disconnect the connector going from the ignition switch to the relay.

Installation: Installation of a new lock is carried out in the reverse order of removal.

Checking the contacts of the wire block:

1) First, remove the lock from the car using the text above.

2) Next, using an “Ohmmeter” or a “Multi-meter” with the “Ohmmeter” function enabled on it, connect its leads to the electrical connector and then look at the readings of the device.

Note! The device should clearly display “0”; otherwise, replace the contact group!

Replacing the contact group:

1) First, on the removed ignition switch, use a screwdriver to unscrew the screw that secures the ignition switch cover.

2) Then use a screwdriver to press out the two plastic latches securing the lock cover.

3) Then remove the cover.

4) And finally, remove the contact group from the ignition switch.

Note! Installation of the contact group is carried out in the reverse order!

Important! Not on all cars of the Samara family the ignition switch is attached to the steering column with four bolts; on some cars it is attached only with two bolts and on top it is secured with a hook indicated by a red arrow!

Additional video material: Below we have prepared a video related to replacing the ignition switch on cars of the Samara family.

Repair and replacement instructions

Basically, the protection zone can be repaired. Repair usually consists of replacing the core or contact group. If the problem remains after repair, then the ignition switch needs to be replaced.

Core of ZZ VAZ 2109

On a VAZ 2109, replacing the core consists of the following steps:

First, the protective and decorative cover is removed from the steering column, as well as the windshield washer and turn switches.
The lock is secured with screws and a hook latch. There may be problems with unscrewing the screws, since their heads are cut off. To remove them, you first need to loosen them with chisels and then unscrew them with pliers. You can carefully drill out the screws.
Next, we disconnect the clamps, disengaging them.
By pulling out the side pin, you can remove the core. If that doesn’t work, the core can be drilled out using a thin drill. In extreme cases, you will have to dismantle the entire assembly.
The next step is to disconnect the connector, wire plug, and ground wire.
By releasing the latch, you can remove the cover and contact group.
We insert a new core and check the work. When you turn the key, all processes should work.

The steering wheel lock should also be checked. If the steering wheel does not lock when turned fully, you need to adjust the position of the lock on the column.

Replacing the contact group of the VAZ ignition switch comes down to dismantling the ignition switch: the removal diagram is described above.

When performing the procedure, the following recommendations should be followed:

before disconnecting contacts, it is advisable to assign numbers to them, this will help to avoid errors when connecting;
If there is a retaining ring in the design of the contact group, you must first remove it using an awl.

Knowing how the ignition switch on a VAZ 2109 works, and having at least a little experience, you can carry out the repair yourself without resorting to the help of specialists. This way you can save on maintenance costs.

Design and principle of operation of the lock assembly

On a VAZ 2109 car, 2 standard modifications of the lock can be installed. The old one has catalog number 21080-3704005-60. It features four key positions (long), and also contains an ignition relay. The new unit with catalog number 21080-3704005-30 has only three key positions and does not have a relay.

To connect all the wires to the VAZ 2109 car lock, a contact group is used. Each of the key positions has its own blocking, and therefore consumer groups.

Contacts “30” and “30/1” are closed. All dependent power circuits are disabled.

In this position, voltage is supplied to the elements of the ignition control system. To do this, the white and brown wires are connected, and the pink wire is connected to black and blue. In this case, several groups of contacts are formed. For example, “30 INT” turns on the power supply circuit for external lighting, including high beam lighting, and the dashboard lighting. Contacts “30/1” and “15/1” provide voltage to the direction indicator lamps, reverse lights, elements of the ignition system, etc. The pair “30/1”, “15/2” powers the low/high beam headlights, fog lights , washer, fans.

The ignition relay, which was switched on in the previous step, continues to operate. The main one is a pair of contacts “30”, “50”, which provides voltage for the starter to operate. In parallel to it, circuits should be formed from contact connections “30/1”, “15/1”, as well as “30/1”, “15/2”. The consumers that are connected in this case are similar to those described for position “I”. The pink wire in the contact pair, together with the black one, is shorted to red (instead of blue).

Used to supply voltage to the components of the parking (“30/1 P”) and side lighting/dashboard lighting (“30 INT”) components. The black wire forms a closed circuit with the brown and pink wires.

The lock and its circuit perform two functions: electrical and mechanical. The essence of the first is to close certain groups of contacts based on the position of the key. From a mechanical point of view, when the ignition is turned off, the steering wheel is blocked, making it impossible to rotate. That is, the second function is protective.

Power-up modes used

Lada 2105 Bright White 15 R Logbook Installation of steering column switches for a Chevrolet Niva ignition switch for a VAZ 2110
At each of the turns, the connection of certain devices is provided. There are markings in a circle in front of the socket indicating the position to which a certain mode corresponds.

Null

To activate this mode, just insert the key into the “secret”. In this case, devices that are directly connected to the battery remain active.

Additional consumers will be put into operation after the larva is rotated at a certain angle. Voltage is supplied to pins 30/1 and 30.

The first is “ignition”

In the first position, the driver can turn on the front lighting, such as the low and high headlights. The tidy and interior light up responsively. The connection diagram for the VAZ-2109 ignition switch is activated during this turn, releasing current to the 30–INT pair.

When there is a connection between terminals 30/1 and 15/1, the rear lights, reversing lights, turn signals are operational, and the generator excitation winding is energized. The XX solenoid valve also receives power.

In this position, contacts 30/1 and 15/2 are closed, which ensures the operation of, in addition to the head light optics, the functioning of the fog lights, the rear window wiper and its heating. The headlight cleaners, heater fan and engine cooling system propeller are connected to this contact.

The second is the “starter”

By moving the key to the current position, the driver does not block the connection of electrical consumers that were started in the previous “ignition” position. This fully applies to both the closed contacts of the pair 30/1 - 15/1, and to the pair 30 - INT.

The main change that the VAZ-2109 ignition switch connection diagram provides in such a situation is the activation of a pair of contacts 30–50. This allows the starter to start.

Third – “parking”

At this angle of rotation, consumers started in the “ignition” position and closed contacts 30 – INT remain activated. A closed pair 30/1 - P is also added. It is responsible for the parking lighting.
