Ignition switch pinout for VAZ 2109 injector. 2101-2107-2109-2110

To start the car and set it in motion, the first thing we must do is place the key in the ignition, thereby starting the engine. Also, with the help of this device we can shut down the engine and control the electronics modes.

The ignition switch is the starting mechanism of electrical equipment that supplies voltage to the electrical circuit. The starter spins the engine using the flywheel, a large disc with teeth located between the clutch and the engine. During starting, the teeth of the starter and flywheel are brought into mesh position. At this time, the engine rotates according to a control signal from this lock using battery power.

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:

• 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.

Troubleshooting Methods

There are two methods for detecting faults:

• Visual;
• Diagnostic.

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

Action	The device is working properly	The device is faulty
Turn the key to the right position (ignition)	All electrical equipment turns on	All or part of the electrical equipment does not work
Turn the key to the second position	The starter is spinning	The starter does not work, the traction relay does not click under the hood

But diagnostics allows you to get a more detailed answer. In addition, a visual inspection will not give you the opportunity to find all the reasons that could cause the ignition switch to break down.

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.

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:

1. “” – a mark indicating that all systems, devices and instruments that can be 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);
2. “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;
3. “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;
4. “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:

1. “50” – output responsible for supplying current to the starter (red or purple wire);
2. “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);
3. “30” and “30/1” – constant “plus” (pink and brown wires, respectively);
4. “INT” – external lighting and light signaling (double black wire). Pinout of the lock VAZ-2108, VAZ-2109, VAZ-21099 Pinout according to the old type

Testing the serviceability

The lock's service life is limited. After it fails, it is necessary to repair or completely replace the product. The functionality is checked after inserting the key into the “secret”.

Failures occur due to mechanical wear or loss of contact. The check is carried out by turning the key. If it begins to jam, then as a temporary solution it is possible to use silicone grease by dripping it inside.

In order for the wiring diagram to function correctly, you need to know which contacts to connect to each other. Typically the following wiring system is used:

• red connects to the cable from the starter;
• the pink wire goes to “+” from the 12 V battery;
• brown +12 V is used to start the ignition relay;
• white – relay on;
• black and blue connect other consumers.

It is necessary to check the contacts for the presence of carbon deposits or the possibility of oxidation. Burning contacts can be heard in the cabin by the characteristic smell of burnt insulation.

Voltage is supplied to the electrical power circuits of consumers of electrical equipment of VAZ 2108, 21081, 21083, 2109, 21091, 21093, 21099 vehicles through the ignition switch (lock).

For current unloading of the ignition switch contacts, an ignition relay 113.4737-10 is included in its circuit, which is mounted next to it under the instrument panel.

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.

Symptoms of a problem

What are the symptoms of a failed ignition switch? Let's start with the fact that its malfunction can be either mechanical or electrical in nature. In the first case it is:

• lock jamming in one of the positions;
• inability to unlock the steering shaft;
• turning on the ignition with a non-original key or other object.

If the lock has an electrical problem, you may notice the following symptoms:

• the warning lights on the instrument panel do not light up or light up and go out periodically;
• the starter does not start;
• Some or all electrical appliances, the circuit of which is powered through the ignition switch, do not work (cigarette lighter, headlights, washer, wipers, etc.).

Scheme of VAZ and car ignition switch

The structure of a car ignition switch

• Locking rod
• Frame
• Roller
• Contact disc
• Contact sleeve
• Block
• 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.

Malfunctions

Considering that the ignition switch is designed to perform two functions, all breakdowns are divided into mechanical and electrical. Mechanical malfunctions include jamming of the cylinder in one of the positions when it is impossible to turn the key. Contact group, which is time to change when the car engine does not start when you turn the key or deformation has occurred.

In a situation where there is no contact, all components of the system do not function. If there is a contact in the wrong place, a short circuit and overheating will occur, which will lead to the need to install a new lock.

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.

Repair and replacement instructions

Basically, the protection zone can be repaired. Repair usually consists of replacing the core or contact group. If after repair the problem remains, then it is necessary.

On a VAZ 2109, replacing the core consists of the following steps:

1. First, the protective and decorative cover is removed from the steering column, as well as the windshield washer and turn switches.
2. 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.
3. Next, we disconnect the clamps, disengaging them.
4. 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.
5. The next step is to disconnect the connector, wire plug, and ground wire.
6. By releasing the latch, you can remove the cover and contact group.
7. We insert a new core and check the work. When you turn the key, all processes should work.

The device provided for such an operation - the ignition switch - helps start most cars and drive further. It is equipped with both foreign-made cars and products of the domestic automobile industry, in particular, our “nines”. Breakdown or malfunction of this element will create difficulties for the driver to start the engine.

Having abandoned the left-hand drive position as in the “classics”, the designers took care of a comfortable right-hand place for using the key in their first front-wheel drive cars. This added ergonomics to the cabin. To perform its function, the main element used to start the car is equipped with two components:

• mechanical;
• electric.

The first block is responsible for fixing the steering wheel while the key is removed. The second block contains the pinout of the VAZ-2109 ignition switch, which is entrusted with the mission of supplying voltage to consumer electrical appliances.

The developers have provided for the presence of certain electrical devices in the ninth Lada model, which are capable of operating regardless of the state of the ignition unit. These include:

• car flashing emergency lights;
• “stops” of rear lights;
• dimensional optics;
• interior lighting;
• instrument panel light bulbs.

It must be taken into account that the VAZ-2109 ignition switch circuit is adjusted to its direct variety. Two types of locks can be installed in the “nines”:

• late model, which has three positions, does not use a relay and is activated with a short key;
• an early example that has four detent positions, a built-in relay and a long key.

Typically, drivers can easily visually determine the type of system installed. You can navigate by the working length of the key
