How to disassemble the ignition switch of a VAZ 2108

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”.

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.

Malfunctions of the ignition switch of the VAZ 2109 and their correction

Malfunctions of the ignition switch of the VAZ 2109 are quite common. This element consists of two parts: mechanical and electrical. Because of this, malfunctions of the ignition switch on the VAZ 2109 can pose a big problem for many, which they cannot cope with on their own. This publication aims to familiarize the reader with all known malfunctions of the ignition switch and explain how to fix them.

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.

Scheme

Below is a typical diagram of the ignition switch on the “nine”.

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”;

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.

Common faults

Among them, the following are in first place:

The lock is jammed. This is even observed in the “nines” when a new lock is installed. The reason is a manufacturing defect or what is given below.

Note. The lock may also jam due to problems interacting with the starter. In this case, you need to inject a little silicone grease inside the lock and do this every time the lock jams.

The lock may wear out over time and this will cause it to perform poorly;
The ignition switch easily becomes unusable in the event of an unsuccessful attempt to steal a car, as well as any careless handling.

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.

Repair and replacement

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”.

Ignition switch VAZ 2109

The ignition switch of the VAZ 2109 is designed to start the car engine. In this article we will look at replacing the ignition switch and its connection diagram (pinout).

The switch, also known as the ignition switch, plays a huge role in the “starting” system of the VAZ 2114 car. It takes part in the operation of the starter, headlights, turn signals, power windows and other elements of electrical circuits. Today we will talk about the ignition switch of the VAZ 2114, the reasons for its replacement, the dismantling procedure and much more.

Video “Replacing ZZ”

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

Replacing the ignition lock cylinder of a VAZ 2109

and the entire castle

Ignition switch for vases with cylinder assembly

ignition switch cylinder of the VAZ 2109, despite its small size and completely inconspicuous placement, plays a major role in the operation of the car's systems when assembled with the lock. Therefore, the failure of such a small unit can completely immobilize the operation of the entire car.

The ignition switch is used to turn on the power to the entire ignition system and start the engine, windshield wipers, reversing lights, turn indicators, and in some modifications even the radio and headlights. In addition, on some cars the ignition switch is additionally equipped with an anti-theft device that blocks the steering wheel from turning.

On a VAZ 2109, replacing the lock cylinder is painfully simple. The only important thing is to study the execution sequence and select a tool.

Troubleshooting Methods

There are two methods for detecting faults:

Ignition switch circuit

We suggest studying a visual method for determining a malfunction or breakdown of the contact elements of the ignition switch using the table.

To work, you will need a mini-tester and a multimeter in ohmmeter mode:

Disconnect the power supply from the ignition switch. To do this, you need to remove the skin from the steering column;
Switch your multimeter to an ohmmeter;
On the block coming from the lock you need to find pins 7 and 4, which correspond to pins 15 and 30;
Connect the multimeter probes to them;
Turn the key to the “Ignition” position;
On the block, find pins 7 and 3, corresponding to 50 and 30. Also connect a multimeter to them;
Turn the key to the second position - Start the engine;
If serviceability is present, the device will show zero resistance in both test cases.

How to determine the malfunction?

The visual method is to check the behavior of the machine at different key positions. First, the key is set to the right position - “ignition”. If the unit is working properly, then all electrical equipment works. If there are any problems with the electrical system, either all or part of the electrical equipment does not work.

Turning the key in the lock

In the second position of the key, the starter should start. If it does not spin and you cannot hear the click of the retractor relay under the hood, then it is possible that either the starter or the starter is faulty. More specific information can be obtained using diagnostics. This is done with a multimeter set to ohmmeter mode. To carry out diagnostics, you need to remove the steering column cover.

Next you need to do the following:

Disconnect power from the 3Z.
Next, find pins 4 and 7 coming from the node. They correspond to pins “30” and “15”, and connect the multimeter terminals to them.
Then the key in the 3Z turns to the first position. If the unit is working properly, the resistance should be zero.
Then the operation of the unit is checked when the key is turned to position II. Likewise, the multimeter should show zero resistance if the circuit breaker is working properly.

Once you are convinced that the protection device is faulty, it must be replaced (the author of the video is Region 4253).

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.

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.

Purpose and device

The main purpose of the lock at first was to protect the car from theft, but:

Now, 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 defense from the castle was previously justified, but now it is “so-so”
Equipped with modern technologies and devices, advanced car thieves are able to hack the electrical 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 Russian 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 occurrence of a malfunction in the ignition switch increases the possibility of vehicle theft by a couple of times, in addition, it creates huge problems for you and, according to the law of meanness, at a completely inappropriate moment for this
The device 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 appropriate sequence
Already at the moment, all Russian cars successfully use switches that have a similar design and procedure for closing contacts

Installing a new device

Now you can finally proceed directly to replacing the broken or worn out ignition switch on your VAZ2114 car.

To do this, follow the following sequence of actions:

Insert the key into the new lock and turn it to the first position. This will allow the latch, which is responsible for locking the steering shaft, to hide inside the housing structure;
Insert the lock into place following the reverse dismantling sequence;
Install the four retaining bolts and tighten them slightly.

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.

“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.

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!

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.
