Wires of the ignition switch of the Niva 21213 car, diagram

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:

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

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).

Let's sum it up

As you can see, ignition switches may differ from each other in connection type, functionality, purpose and other parameters. At the same time, all of them are structurally quite simple, which makes it possible for any car owner to correctly troubleshoot problems when identifying a malfunction.

As a summary, we note that the presence of a chip simplifies the connection, but this solution is often missing on older models. To avoid mistakes, without enough experience in this case, it is better to contact an experienced auto electrician who will quickly fix any problems with the ignition switch.

The structure of a car ignition switch

1. Locking rod
2. Frame
3. Roller
4. Contact disc
5. Contact sleeve
6. Block
7. Protrusion of the contact part.

The lock mechanism is connected to many wires. They continue from the battery, connecting all the electrical devices of the car into a single chain. When you turn the ignition key, the electrical circuit is closed from the “-” terminal of the battery to the ignition coil. As a result, the current passes through the wires to the ignition switch, through its contacts it is directed to the induction coil, after which it returns back to the “+” terminal. As electricity passes through the coil, it generates high voltage, which it transmits to the spark plug. Therefore, the key closes the contacts of the ignition circuit, thereby starting the car engine.

Characteristics of a contact group

To begin with, we suggest finding out why an ignition switch contact group is needed, what its structure is and how it works.

Purpose and functions

In essence, KGZZ is used to ensure the connection of all electrical circuits of the vehicle without exception. That is, when the driver turns the key in the lock, the KGZZ closes the contacts, thus allowing the use of all electrical devices without exception.

Device

Diagram of the lock The ignition switch itself is a simple circuit breaker. When you turn the key, the contacts are adjusted, making it possible to start the engine, power the equipment, and also stop the power unit. If you disassemble the body of the lock itself, you will see that the device itself is located inside it, as well as a large number of wires connected to each other. The wires to the lock come from the battery.

The contact group of the ignition switch itself goes directly to the connection point of these electrical devices. To prevent short circuits and to delimit the contact elements themselves, the KGZZ is mounted in a plastic case.

Principle of operation

An automobile ignition system can be either battery-based or generator-based. Their fundamental difference is that battery ignition is equipped with an autonomous power source; accordingly, all electrical equipment can be turned on without starting the engine. As for the generator system, in this case, activation of electrical equipment is possible only after starting the engine.

When the driver turns the key in the lock, the electrical circuit contacts are closed from the negative terminal on the battery to the coil. At the same time, voltage begins to flow through the wiring to the lock, which is supplied to the coil through contacts, after which it returns to the positive output of the battery.

At the moment when the voltage passes through the coil, a very high voltage is generated in it, which is subsequently transmitted to the spark plugs. Ultimately, the contacts close and the engine starts. In addition to the ignition circuit itself, there are other electrical circuits in the car that conduct voltage from the key to electrical appliances. Each of the wires is responsible for connecting the contacts to each other (the author of the video is the Auto Repair and Maintenance channel).

Basic faults

Briefly about the reasons why repair of the ignition switch contact group may be required:

1. Overloading of the device, which may be due to the installation of additional devices of increased power, as a result of which a higher voltage will pass through the KGZZ. For some time, the device can cope with this current, but over time, carbon deposits will begin to form on it. It should be noted that this deposit, as a rule, appears precisely inside the contact, and not on its surface, then the only way out is to replace the contact group. To prevent this problem, all additional devices must be connected via fuses or relays.
2. Short circuit in the electrical network. If a short circuit occurs, this may also cause high power voltage to pass through the CGZZ, which again will cause its failure.
3. Many motorists who changed the KGZZ faced the problem of abrasion of the tracks, as well as the contacts themselves. This problem usually occurs as a result of wear and tear on the lock, but in some cases the cause may be faulty.
4. Mechanical failure of contact elements, as well as other components of the group.
5. Overheating of the device, which can lead to damage to the design of the CGZZ. Overheating, as a rule, also occurs as a result of increased load on the device. When working in conditions of elevated temperatures, the tracks may move or even break (video author - AlexAvtoKhlam).

Replacing the ignition switch on a VAZ car

To carry out repair work to replace the ignition switch of a vase, we will need: a screwdriver, a tester and a thin awl. Once you have everything you need, you can begin the repair. On all classic VAZ cars, the ignition switch is located at the bottom, on the left of the steering column. To replace you need:

1. Disconnect battery
2. Remove the plastic casing by first unscrewing the screws that secure it.
3. Then unscrew the two screws securing the ignition switch to the bracket.
4. We insert the key and set it to position 0 to disable the anti-theft device.
5. Insert the awl into the hole in the bracket and press the latch. Then we take out the lock itself.
6. After removal, it is recommended to mark the contact wires so that nothing is mixed up the next time you connect.

Removing the ignition switch on a VAZ-2106 begins with disassembling the steering column casing. We unscrew the five bolts and remove its halves. Before you begin disassembling the electrical part of the lock, it is very useful to disconnect the battery by removing the negative terminal or unscrewing the switch bolt. After this, remove the spring retaining ring from the back of the lock body and remove the contact group. We move it to the side so that it does not interfere, and we begin to remove the lock itself.

It is secured in the steering shaft bracket with two bolts, after unscrewing which nothing happens. It is useless to try to remove the lock from its socket if you do not know about the special stopper. It is located on the lock body under the bracket. We press this stopper into the lock with a thin screwdriver through a small hole in the bracket. Further, according to all the instructions, the lock should be pulled out freely, but this does not work.

An obstacle that is not described anywhere is the anti-theft rod. Even though it is in a “disconnected” state, it still clings to the steering shaft. To remove the lock, you have to manipulate the key. In different positions of the lock cylinder, the anti-theft device also moves and is recessed as much as possible when the key is in the “Starter” position. After a few minutes the lock can be pulled out of the bracket.

Here is the time to write that assembly of the unit should be carried out in the reverse order of removal. And in general, this will be true. First you need to insert the new lock into the bracket, recessing the latch and holding the key in the starter position, tighten the fastening bolts, then connect the wires. Particular attention must be paid to this, because an incorrectly connected contact group can damage the starter or ignition system. We reconnect the wires from the old group to the new one one at a time, checking the numbers on the contacts. After this, we assemble the steering column casing.

On the car, the ignition switch is located on the driver's side, mounted on the left side of the steering wheel on the steering gear bracket, under the instrument panel.

First of all, you need to get rid of the decorative casing of the steering shaft, unscrew the fastening screws and remove it. We performed similar actions when replacing the steering shaft.

After removing the decorative casing, unscrew the two screws securing the ignition switch to the body, then insert the key into the lock and turn on the “0” position, which turns off the anti-theft device. Through the hole in the bracket, press the lock lock with a thin awl and remove the ignition switch from the mounting socket. This completes the repair work to remove the ignition switch.

On VAZ 2108 and higher models, a package with wires is connected to the lock, that is, nothing needs to be marked and the possibility of mixing up the wires when installing a new switch is completely eliminated. Well, on VAZ 2107 and lower models, this is not the case, each wire is connected separately, so when removing each wire, it must be marked so as not to be confused during further installation.

To replace the contact group of the ignition switch, you need to use a thin screwdriver or an awl to pry the retaining ring from the edge and remove the contact part. When installing a new contact part, orient it so that terminals “15” and “30” are on the side of the locking rod.

At this point, the repair work is completed, install the new ignition switch in the reverse order of removal, connect the wires, transferring the markings from the old switch to the new one. The pinout or connection diagram of the VAZ ignition switch wires is quite simple and understandable, so every car enthusiast can carry out repairs or replace a spare part without the help of car service employees.

Prevention

To prevent breakdowns, the manufacturer recommends following several tips.

• Once a year, treat all terminals and connectors with special oil - this will prevent the formation of oxides.
• Periodically check the tightness of the contact connectors. If the connections are loosened, short circuits may form or the conductivity of the circuit may decrease, which will be perceived by the ECU as a mechanism failure.
• Check the degree of wear of power cables and lines. During active use of the vehicle, braids made of flexible polymer may wear out and crack. This circumstance can provoke short circuits and mechanical shedding of insulators. Therefore, it is better to prevent a breakdown than to fix it.

If you adhere to the above rules, the car will serve for a long time and with high quality all the time.
