Connecting the ignition switch VAZ 2121

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.

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).

The electrical circuit of the VAZ 21214 Niva injector is used to monitor the condition of the car. Reduced luminous flux, short circuit, liquid ingress - all this leads to disruptions in the operation of the electrical circuit of the model 2131 injector. With the advent of new technologies, the situation has changed - electrical wiring has become a key element of the car.

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.

Currently, problems with a car’s electrical system can be corrected at any car service center, but for those who like to fix everything themselves, an electrical circuit will come in handy. The electrical diagram of a VAZ 21214 with an injection engine is a graphical representation that shows the order and connection of the elements in the circuit, but does not show the actual arrangement of the elements. But even the most inexperienced car enthusiast will be able to understand something in the electrical circuit of the VAZ 21214 and fix a small malfunction on his own, which will help save time and money.

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:

Disconnect battery
Remove the plastic casing by first unscrewing the screws that secure it.
Then unscrew the two screws securing the ignition switch to the bracket.
We insert the key and set it to position 0 to disable the anti-theft device.
Insert the awl into the hole in the bracket and press the latch. Then we take out the lock itself.
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.

Chevrolet Niva hub - replacement

To replace the wheel bearing in the field, you need to pull out the hub. This is carried out according to the following plan.

1. Dismounting the conical bushing.

2. Unlocking the nuts. The problem may lie in the fact that they often lick off or turn sour. In this case, you can use a chisel and a light hammer.

3. Use the nineteenth socket or wrench to remove the lever clamps. They are located both front and back.

4. The locking plates are removed. These are metal perforated strips that are often overlooked.

5. The seventeenth and tenth keys require removing the circuit pipes.

6. A stop is installed under the lever. Using two twelfths keys, unscrew the nut fixed on the upper arm retainer bolt.

7. The lower block is also unscrewed in the same way.

8. When there are no fasteners left, it is possible to pull out the entire system at once.

9. By fixing the steering knuckle with a clamp, you can knock out the hub.

10. After this, the screws securing the knuckle to the lever mechanism are removed.

Knowing the structure of the front wheel hub of Niva 21213, you can carry out repairs yourself, without contacting a service center.

From the ignition switch (terminal 15), connect the wire to the coil (terminal +B) to a test lamp;
Connect its negative terminal to ground;
Turn on the ignition - turn the key in the lock to position “II”;
If the control lamp lights up, then the circuit is working. If not, look for damage to the wire;
With the ignition on, pull out the central wire from the coil from the distributor;
Bring its metal tip to the cylinder block so that a gap of 3-4 mm forms between them;
Turn on the starter for a few seconds;
If the spark jumps, the coil is working.

Tip: you can quickly check the switch in one way - take it from a working car. If the car starts with the new switch, then you need to buy a new one.

Generator Differences

It was already mentioned earlier that the wiring diagram of the VAZ 21213 had some differences, primarily related to the installed power unit.

In particular, fuel-injected versions required a more powerful generator, so:

A generator model 371.3701 was installed on the VAZ 21213;
The VAZ 21214 was equipped with generator model 9412.3701.

They are structurally similar and are synchronous AC machines with a built-in rectifier and output voltage regulator.
