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.

Laughter in the topic: The wife left on a business trip. The husband wakes up the child and takes him to kindergarten. They came to one, and they were told: - This is not our child! They came to another - the same story. They get on the bus and go, then the child says: - Dad , I'll be late for school in another kindergarten!

I replaced the ignition switch today, the old one was spinning 480 degrees, it was not clear where the ignition was, I couldn’t get the key in or out! It turned out to be very simple to replace the ZZ:

- remove the trim under the steering wheel - turn on the ignition - press into the hole on the side with a screwdriver - remove the seal towards you - install a new one

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).

Ignition switch and features of its replacement

Before removing the ignition module on a VAZ 21213 carburetor or injector, it is necessary to diagnose the ignition coil, distributor and spark plugs. As practice shows, spark plugs are often the cause of incorrect operation of the internal combustion engine. If you are sure that the problem lies in the fault, then the installed device will need to be changed.

How to replace the Niva ignition switch:

  1. First, the battery is disconnected and the steering column is removed.
  2. You need to mark the wires that are connected to the contact part of the VAZ ignition switch and disconnect them. Using a flat-head screwdriver, remove the bolt securing the system switch to the steering column bracket. You will also need to unscrew the screw that is located below, on the right side of the first one.
  3. Next, on Niva 21213 you need to turn the key to position 0, after which you need to use a screwdriver to slightly recess the device lock through the hole. The hole itself is located on the side of the steering column. Do not touch the exposed key.
  4. Before removing the ignition switch on the Niva, you need to pull it slightly towards you, after which the device is dismantled. In accordance with the connection diagram, the contact part of the device is replaced; to do this, you need to pry it off with a screwdriver and remove the retaining ring.
  5. Next, the contact part of the assembly is removed and changed if necessary. During installation, the rotating part must be turned counterclockwise using a screwdriver. Remove the key from the structure and install the contact part so that its wide protrusion can coincide with the wide cavity of the housing. Further assembly of the unit is carried out in reverse order.

How to check the ignition module?

After installing and connecting all components, you need to diagnose the functionality of the module:

  1. First, the resistance between the terminals of the secondary winding is measured - the probes are connected to cylinders 1 and 4, and then to 2 and 3. The indicators can be any, the main thing is that they more or less coincide. A malfunction of the secondary winding will be indicated by an error in the indicators of more than 100 Ohms.
  2. After this, you need to test the wiring; to do this, you need to disconnect the block from the unit and set the multimeter to voltmeter mode, with one tester probe connected to pin A, and the second to ground. Start the engine and watch the tester display - the readings should be about 12 volts, the second contact is diagnosed in the same way.
  3. If there is no voltage, you should diagnose the safety element located in the mounting block under the center console. The reason for the lack of voltage can be not only a blown fuse, but also poor contact, broken wiring, as well as corrosion (author - AutoElectrika Diary channel).

Instructions for setting the ignition

Now we suggest you find out how to set the ignition on a Niva.

On VAZ 21214, 2131 models, electronic ignition is set as follows:

  1. First, cylinder 1 must be set to the top dead center position, while the mark on the crankshaft must be in front of the 3 - 0 degree mark.
  2. Then, to set it up, you need to dismantle the distributor cover and see where the slider is located - it should be directed towards the pin of cylinder 1. Using a strobe, you need to set the torque, after which the ground of the device is connected to the battery negative, and the positive terminal to the positive.
  3. Next, the regulator clamp should be connected to the high-voltage cable on cylinder 1 and marked with a mark on the crankshaft pulley. The engine starts, and its revolutions should be no more than 800 per minute, and the light from the strobe should be directed to the mark on the pulley. If the ignition adjustment was carried out correctly, the mark should coincide with the middle mark on the engine cover. If this is not the case, then the power unit must be turned off, then loosen the distributor fastening either clockwise or counterclockwise. The distributor cover is being dismantled; you need to ensure that the stator petals are aligned with the rotor mark.
  4. Next, the engine starts again and warms up to 80 degrees. Accelerate to 60 km/h and press the gas pedal sharply. If the module is inserted correctly, the engine may briefly detonate at this point.

Signs that it’s time to change the ignition switch

Early signs of a malfunction in the Chevrolet Niva ignition switch usually manifest themselves in the key jamming when it is turned in the cell. Slight jamming is especially common when turning the key from the “Ignition” position to the “Starter” position. Over time, the malfunction progresses and can lead to the key jamming in the cylinder.

At first, this problem can be solved by disassembling the lock and dripping oil into the cylinder, thereby reducing friction in it when turning the key. However, if the jamming progresses, then it is better to replace the lock before its cell jams tightly.

The presence of problems with the ignition switch is also indicated by the key slipping in the cylinder when it cannot be turned to the “Ignition” or “Starter” position. This situation also indicates a breakdown of the larva.

The second group of faults is related to the contact group. The Chevrolet Niva ignition switch is powered by several groups of energy consumers:

  • in position “0” the car’s side lights can be turned on;
  • in position “1” (“Ignition”) the high and low beams, turn signals and tail lights, the fuel pump, power windows, wipers, etc. work;
  • in position “2” the starter starts.

In the case when several energy consumers, seemingly unrelated to each other at first glance, stop working, the problem may lie in a break, breakdown, or oxidation of the contact.

Such a malfunction does not necessarily require replacing the lock - you can repair the contact group by replacing damaged contacts. However, a problem with the contact group may indicate general wear and tear of the lock, so it is better to replace it entirely.

Design Features
On VAZ-2123 vehicles, an ignition switch of type 2123–3704005 is used with an anti-theft locking device, a lock against re-starting the starter without first turning off the ignition, and a communication coil for the ignition key transponder with the automobile anti-theft system.

At the ignition switch, check the correct closure of the contacts at various key positions (Table 9.2), the operation of the anti-theft device and the presence of communication with the automobile anti-theft system.

We change the Shnivy ignition switch. There is a problem

Having removed the casing from the steering column (there are 5-6 bolts on all sides and a rubber round coupling around the lock), we see the following - the lock itself is attached to the column using an additional bracket (on the left), which is attached to the lock itself with very powerful and hemorrhagic breakaway bolts.

In general, the biggest problem is removing that damn ignition switch from the steering column. It is secured with 4 breakaway bolts, which are specifically designed to make it more difficult to steal a car.

Therefore, if you are not going to repair the lock itself, but simply decided to replace it, then do not forget to buy 4 tear-off bolts!

That is, they are easy to tighten; the caps have hexagonal key heads, which, at a certain tightening torque, break and a round cap remains. This is what we will need to unscrew, as many as 4 pieces. It turns out that putting it on is easy, but taking it off is difficult.

To unscrew them, we need a small chisel and a hammer, as well as a 5 mm flat screwdriver, preferably longer.

We unscrew it COUNTER-clockwise, adjust the chisel so that the angle of inclination is sharper, so that the force of the blow goes sideways, and not directly into the head. And we try to make a notch on the head of the breakaway bolt with a chisel; the most important thing here is to remove the bolt from the thread so that, once stuck, it begins to move.

Thus, moving the chisel, punching 3-4 mm at a time, we turn the bolt to the left until it loosens. Then you can unscrew it with your fingers or pliers if it still doesn’t turn well.

This is what such a bolt looks like, it goes to the cone. Let's take on the second one.

The most difficult one will be the one on the upper right; it will be very difficult to climb there.

Having unscrewed the bolts, you have practically won, now you can replace the lock itself without any problems, everything is quite simple, you disconnect 4 wires - red, blue, pink and black. True, you will also have to unscrew the lock itself from the second part of the fastening - using a Phillips screwdriver, 3 bolts.

Repair instructions

The location of the 3Z is known to everyone; this unit is located directly under the steering wheel. To properly replace or repair a device, you must follow the instructions:

First, disconnect the battery and remove the plastic steering column cover, which is secured with bolts. Next, press out the fastening and disconnect the connector with the 33 wiring from the control panel wiring block. When unplugging, be careful not to damage the plug. Having done this, you will also need to disconnect the plug with the 3Z wires from the connector with the wiring of the immobilizer control system. Using a hammer and chisel or a drill, you need to remove the four breakaway screws and remove the assembly from the steering column. You can't just unscrew these bolts. VAZ engineers decided to use this method of installing the protection in order to protect car owners from possible thefts. This method of fastening, as you can guess, makes it very difficult to dismantle the protection, so at this stage you will have to tinker. In any case, the bolts can be dismantled or drilled out, but instead you will have to purchase new ones in advance. After completing these steps, you can bend the connector mount with wiring from the 3Z. The terminals with wires are removed from this connector. Next, you need to compress the latches again and dismantle the plastic cover of the device itself. If you plan to simply change the node, then this can be done at this stage. We suggest that you familiarize yourself with more detailed information on repairs; it is quite possible that simple steps will restore the unit’s functionality and save money. So, if you decide to repair the mechanism, then at this stage you need to press out two more plastic clips and remove the contact group from the cover. Next, it is necessary to carry out a thorough visual diagnosis of the contacts. If you notice that the contacts have oxidized or burnt, you can restore their functionality by cleaning them using fine-grained sandpaper. Get rid of oxidation and plaque, but do not go too hard so that the contacts do not wear off. If the damage to the contacts is too severe, then cleaning will not solve the problem; you will only need to change either the contactor itself or only the contact group. If everything worked out with the contacts, then you can assemble and install the 3Z

During assembly, pay attention to the position of the terminals with the wiring in the connector; under no circumstances should they be mixed up. After completing these steps, install the locking device back into place, while pre-sinking the locking rod of the anti-theft unit. To do this correctly, install the key in the 3Z and turn it to any position, the main thing is that it is not in the “0” position

If the key is replaced, then the transponders, these are special electronic code components on the head of the key, also need to be changed.

Changing the ignition switch

at the cornfield. we face the marriage and get out of the situation.

If you do not do this, then you will also have to carry out the training procedure, as well as change the lock cylinder on the trunk and doors, and this is a rather labor-intensive process. Otherwise, you will have to use the old key to open the doors and trunk, and the new one. Agree, this is completely inconvenient, but this is only relevant for those car owners who have changed their license plate.

Inspection of the larva

A lock without a key looks like this - stoppers stick out in all directions, which catch when turning and thus prevent the cylinder from turning inside.

When you insert the key into the cylinder, all the pins should be removed, thus they will not interfere with the key turning. In our case, we had 1 pin sticking out on the left, which clung and did not allow the “larva” to spin. We worked on it with a file.

Also carefully inspect the lock cylinder; it is quite possible that you will see burrs and even grooves on the upper side that were “trodden down” by the pressure pin running along its top. It turned out that for all the time (and the car is already 10 years old), he made his own move in the “body of the larva” (outer side), which ended in a dead end. And in this position the key was locked (position I - ignition).

There, they also used a needle file to grind off the furrow it made; make the angle as sharp as possible. It is very difficult to explain, so think about how and what should work. The lock cylinder is made of soft material and in 10 years it will definitely wear out, the rear round pin “drills” its path. Point it the right way and you won't have to buy a new ignition switch.

On sale you can find locks with cylinders (3 pieces - for the front doors and trunk) - the cost is approximately 1,300 rubles.

Or take it without the cylinders - it costs 900 rubles, but now you will have 2 keys - one to start the car, and the second to close/open the front doors and trunk. So repairing the lock is a very good option, you win in 2 categories at once - you save money, and you will still have 1 key for everything, as before.
