Reasons for repairing the ignition switch
The ignition switch of the “six” has 4 modes with different functionality:
- Mode “0” allows you to power only wires 30 and 30/1. Other functions are disabled.
- Mode “I” makes it possible to operate the running lights, fog lights, wiper drive, and heater motor.
- Mode “II” - in this case, the electrical wiring on the VAZ 2106 activates the turn signals, instrument panel and ignition system.
- The “III” position of the key provides power to terminals 30/1 and 30-INT. The car starter is working.
Replacing the ignition switch yourself may be necessary for several reasons:
- Firstly, this is possible in case of loss of keys.
- Secondly, over time, the ignition switch cylinder wears out, and this affects engine starting.
- In addition, there may be problems with the contact wire group, which can lead to a short circuit.
Advice: By the way, this work is not difficult to do yourself, although the price for the services of an auto electrician will also not be prohibitive. In order to perform these types of work, prepare in advance an awl and a Phillips screwdriver (and a new ignition switch, if necessary).
On cars of the “classic” family, the location of the lock is below and to the left of the steering wheel. Also see the article about the restoration of domestic classics.
And it consists of the following elements and parts:
- lock body;
- contact disk;
- locking rod;
- roller and contact sleeve;
- block.
Dismantling the old unit
The instructions for repairing the lock yourself will look something like this:
- disconnect the battery;
- unscrew the fastening screws of the plastic casing under the steering column and remove it;
- disable the anti-theft device, for which you need to insert the key to position “0”;
- VAZ 2106 wiring requires removing the lock - for this purpose, insert an awl into the hole and unclip the latch;
- after you have removed the lock (see video), it is strongly recommended to mark the contact wires so as not to mix them up when connecting them back;
- install the new lock in the reverse order.
Replacing the contact group
The VAZ 2106 wiring diagram is designed in such a way that if it is necessary to repair the contact group, this can be done without dismantling the ignition switch. However, if you can remove it, you will almost certainly not be able to put it back. For this reason, we will need to perform all of the above operations.
Important! After removing the lock, pull off the retaining ring from its reverse side and install a new contact group (as in the photo).
It is recommended to purchase only high-quality spare parts, and it is better to do this from trusted car dealers, since today there are many fakes on sale. The distinctive properties of the original ignition switch will be the following:
- the body is cast carefully and with smooth edges;
- the top of the lock is rolled evenly;
- a wide hologram cannot be torn off without destroying it;
- free movement of the key in the cylinder, without interference.

Disassembling and replacing the instrument panel
This technological operation is carried out in the following sequence:
- Remove the front box from the bottom of the instrument panel.
- Pull back the lower locking latches.
- Disconnect the wires and mark each wire as belonging to it.
- Remove the instrument panel.
- Remove all sensors and carefully sort them. This will make it possible to correctly assemble the products.
- When disassembling speed indicators (speedometer) and speed indicators (tachometer), bent scissors used in medicine are used.
A standard replacement of the VAZ 2106 instrument panel is carried out in the event of a defect in one of the sensors, which may fail. Let's consider the question of how to remove the instrument panel using the fuel sensor as an example; other instruments can be replaced in a similar way using a screwdriver and pliers.
The procedure for replacing panel sensors: 1. We remove the instrument panel. 2. Dismantle the fasteners and the fuel sensor grower. 3. Remove the mounting bracket for the instrument panel sensor and remove the sensor from the workplace. 4. Mark the instrument panel diagram of this sensor with a marker and open the electrical circuit. 5. Remove the instrument panel backlight sockets from the body part. 6. Installation is carried out in reverse order. 7. To replace the speedometer on the instrument panel, it is necessary to remove the product fasteners and the trip meter reset button from the outer plane. 8. Then press the counter and remove it from the shield. 9. Remove the two speed indicator fasteners to the fasteners. 10. Remove the fasteners and speed sensor, and mark the working sockets of the warning lamps with a marker. 11. Remove the lamp sockets from the holders in the speed sensor. 12. If necessary, disconnect the device cable. 13. Installation is carried out in reverse order. 14. The tachometer on the instrument panel is replaced in the same way and then connected.
The mode switch is secured on the inside with plastic latches, to remove which you need to press them against the switch body. In the figure above you can see the connection of the VAZ 2106 instrument panel, as well as the pinout of the panel panel elements.

Underhood wiring
The main part of the electrical wiring is located in the engine compartment, where the main elements, electronic and mechanical sensors of the car are located. A significant number of wires reduce the overall aesthetic appearance of the motor, surrounded by multiple cables. For convenient maintenance of the mechanical components of the engine, the manufacturer places the wiring in a plastic braid, preventing it from rubbing against metal elements of the body and hiding it in body cavities out of sight so that it does not distract attention from the power unit.
Under the hood, electrical wiring provides connection to the main elements of the power unit
Under the hood, the engine contains many auxiliary elements that consume or generate electrical energy, such as a starter, generator, and sensors. All devices are connected to each other in a certain way and in the order shown on the electrical diagram. The wires are secured in a safe and inconspicuous place, which prevents them from wrapping around moving parts of the chassis and motor.
Grounding wires are located inside the engine compartment, a tight connection of which is only permissible on a smooth metal surface. A reliable grounding contact through the car body provides a single circuit of reverse current from the negative terminal of the battery, which is the “ground” of the vehicle. The bundled cables from the sensors are placed in a protective casing that provides insulation from heat, liquids and radio interference.
The wiring system located in the engine compartment includes:
- battery;
- starter;
- generator;
- ignition module;
- high-voltage wires and spark plugs;
- numerous sensors.

Troubleshooting
In order to correctly replace the necessary elements of the circuit, when faults are identified, the following procedure must be followed.
These actions are relevant if the car refuses to start:
- Check the battery. Perhaps it just ran out of charge.
- First of all, the section on the circuit from the generator device to the coil is checked. If there are breaks in the circuit, new wires are replaced and connected; if there is oxidation, the contacts are cleaned using an iron brush. If the contacts begin to “crumble,” they also need to be replaced.
- Check the coil for spark. Remove the high-voltage cable from the installation location and bring it to the car body. When you try to start the engine, a spark should jump between the high voltage and the body.
- Check if the spark plugs are working. It happens that the reason for the inability to start the engine is carbon deposits formed on the spark plugs. You can easily clean them yourself; to do this, you need to remove the candles and use the instructions that you will find here.
Weak points in the fuse box
- Poor connection of the fuse itself to the seat, which leads to burning of the sockets.
- During operation of a car, fuses always get hot, as a result of which they also negatively affect the sockets located nearby.
- The unit must be checked regularly, since the cost of fuses is always low, and this corresponds to their not particularly high quality and reliability.
Sorry, there are no surveys available at this time.
VAZ2107 fuse and relay diagram
The electrical wiring of the machine is protected by fuses, which are mainly installed in the central and additional units, located at the bottom of the instrument panel on the left side next to the steering column. The circuit from the battery to the terminals and connections is closed when the car ignition is turned on.

Owners of 2106 should be aware that the old design of fuses has long become obsolete, since each time they operate they overheat, which affects the density of the cells. Lack of tight contact between the fuse and the connectors leads to their burning. Therefore, replacement of the fuse blocks is necessary. To avoid unnecessary problems with the electrical wiring, you should inspect the safety devices every six months. If the contact part burns, it is necessary to replace the fuses and clean the sockets. Today, many VAZ 2106 owners are modernizing classic blocks, replacing them with modern blade fuses.
General tuning aspects
The simplest tuning of the VAZ 2106 dashboard is to purchase a ready-made set of accessories and replace standard instruments. You can install it yourself using the instructions included with the kit. More labor-intensive is the tuning of individual devices, which involves replacing stickers and arrows.
1. Dismantled devices for replacement
2. LED instrument lighting
3. Tuned six panel
When changing arrows and stickers, you need to be careful, as these parts are very fragile.
Tuning the VAZ instrument panel can be done by replacing the meter dials with white ones and installing overlays on the panel. You can cover the panel with artificial leather or leather if you have sufficient funds. Before stretching the material, the surface of the shield must be cleaned and then adhesive must be applied in an even layer. Next, press the leather or substitute over the entire surface and wait until the glue dries. At the last stage, you need to process the edges, giving it an aesthetic appearance.

LED panel lighting
The most popular lighting for VAZ 2106 devices is LEDs. The panel looks especially beautiful at night. LED lamps of various colors are used for illumination. At least 2 bulbs are installed on the speedometer and tachometer dials. For small sensors, one LED is sufficient.
LED lighting around the entire perimeter will look more impressive. LEDs must meet the 12-volt voltage of the on-board network. When installing LEDs, be sure to observe polarity. Thanks to tuning, the VAZ 2106 tidy takes on an individual look and becomes more convenient and functional.
