Ignition switch VAZ 2121 wiring diagram

About the castle

The ignition switch on the Niva is a part that has a mechanical and electrical part. Each part is responsible for specific functions. The mechanical part protects the car from turning on the ignition with another key and increases the car’s protection against theft. The electrical part (contact group) is responsible for closing the power supply and vehicle control circuits.

Each of the parts can fail, which will lead to the inability to start the engine or stop it altogether.

Features of the modification

First of all, the changes affected the engine management system and control instruments. In particular:

1. The wiring diagram for Niva 21213 received an additional wiring harness in the engine compartment for connecting a microcontroller and sensors;
2. On the Niva model of recent years of production, a more advanced power unit with the VAZ-21214 index is installed. Instead of a carburetor, it has a fuel frame with injectors from GM. The price of a car with injection has increased because of this;
3. The instrument panel has changed - the design is borrowed from the VAZ 2108 model.

Breakdowns

Most often, the contact group fails, since it is made of plastic into which copper contacts are inserted; due to the flow of high currents and weak contact between the brackets, heating occurs. Due to high temperature, the plastic is deformed and damages the contact group.

The mechanical part fails much less often, but it also happens. It becomes damaged due to prolonged use, the springs in the lock sag, the lock becomes loose, which leads to its jamming or the ability to turn it with almost any key, which reduces the car’s protection to zero.

Differences between ignition switches

The ignition switches on the Niva are different; on the older VAZ 2121, the ignition switch is from the VAZ 2106, and on the Chevrolet Niva, the ignition switch is from the VAZ 2110.

Ignition switch on Niva until 2009. does not have a common connector, and the wires in it are connected separately. Quite often, when people remove the contacts from the lock, they forget their position and this complicates the assembly process, so it is best to mark the wires first, but if you have already removed the wires and now do not know how to connect them, then you can use the picture below indicating the color of the wires and their connections to a specific contact.

Guys, what kind of ignition switch can be installed from the company so that there are more positions? no one came across this? I really want to! so that I can pull out the key and I’m thinking about doing something like this, but I’m worried about the relays. I have a Niva 21213 carb.

VAZ ignition switch pinout

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.

How to replace the ignition switch of a VAZ-2121 car

To turn the car's electrical circuits on and off, use the ignition switch or simply the ignition switch. A mechanical anti-theft device is installed in the ignition switch, blocking the steering wheel rotation. The anti-theft locking rod extends when the key is placed in the “parking” position and removed from the lock. After this, turn the steering wheel so that the rod fits into the groove on the steering shaft, locking it.

The locking rod is recessed, releasing the shaft, when the key is turned from the “parking” position to the “off” position. The closure of the ignition switch contacts at various key positions and the switched circuits are shown in the table. The power supply circuits for the horn, brake light, hazard lights, cigarette lighter, lamp, plug socket for a portable lamp and high beam headlights are always turned on (regardless of the position of the key in the ignition switch).

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).

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.
