Modifications of mounting blocks and fuses of the VAZ 2112 have changed more than once during the production of the model. Radical innovations were introduced only in 2002 after the appearance of a 16-valve injector.
In 2006, there was only one unit in the cabin, and in 2007 a console unit was added to it. This happened thanks to changes in the shield and gearbox, and the addition of a Europanel. The cover of the main unit became hinged, which simplified access to the fusible elements. Separate inserts outside the mounting blocks, for example, under the brake pad, have been preserved.
VAZ 2112 fuse diagram
With an 8-valve and 16-valve engine, it is equipped with a main mounting block, and since 2008 an additional console has been added. A diagram with element markings is printed on the left side of the main block cover and placed below.

Starter, ignition, rear fog lamp relay
In order to carry out quick checks and repairs, the ignition system relay is installed under the front dashboard of the car, behind the hood release handle. It is located just below the central dashboard. The module is closed with a plastic plug, which must be opened slightly to test for functionality.
Starter, ignition, rear fog lamp relay
Next to the indicated relay, there is a similar one for the rear fog lights and the starter.
The main task of the relay when igniting is to reduce the applied load to the contacts. When the engine starts, the relay turns off some electrical circuits in the vehicle system. The system is used not only in injection, but also in carburetor engines.
In the event of a malfunction or malfunction in the ignition system, it is necessary to monitor the operation of the relay. For this purpose, open the box and carefully remove the desired element. It is attached using contacts to special grooves. The first thing to do is look at the oxidation of the contacts, if necessary, clean them with a soft cloth or treat them with a special liquid.
To check functionality, you need to use a regular multimeter. We connect to incoming connections and check the numbers. If there is no short circuit when current is applied, it means the element is not working. Replacement is carried out in a similar manner. It is necessary to use a standard element with the number of amperes indicated on the housing.
Location
The relay and fuse mounting block is located on the left side of the steering column in the instrument panel.

Cigarette lighter diagnostics and repair
If after replacing the protective element the element does not start working, then the reason must be looked for elsewhere. It is not always necessary to install a new device; you can repair the cigarette lighter. First of all, you need to check the wiring that goes from the network to the socket. You should test the wires with a multitester. If there is no power during diagnostics, this indicates a broken wire. Repairs will require new parts, rosin, tin and a soldering iron.
The second malfunction, which does not require a complete replacement of the cigarette lighter, is the breakdown of the mica fuse, which is located inside the device. To do this, you need to disassemble the socket of the socket and find a small mica semiconductor (it may melt). It is dismantled, replaced with a new one, after which everything is put back together and the functionality of the device is checked.
How to remove the cigarette lighter of a VAZ-2110
To remove the cigarette lighter on a VAZ, you need:
- Open the hood. Then remove the negative cable from the battery and take out fuse F18.
- Unscrew the fasteners and remove the 2 parts of the cladding.
- Pull out the three-pin plug.
- Remove the trim under the handbrake and the cover from the gearbox.
- Move the seats back, unscrew the tunnel fasteners and pull out the cartridge.
- Pry the cigarette lighter latch and remove the socket for repair.
Connecting a new
The cigarette lighter is connected in the reverse way:
- A working device is installed.
- The facing casing of the gearshift lever and handbrake is mounted in place.
- A three-pin plug is connected.
- Then you need to connect to power.
- Check the correct connection and functionality of the cigarette lighter.
Pinout
The layout of the elements is as follows:
- The red wire is responsible for the plus and is connected to the device through fuse No. 18. It is capable of passing a current of no more than 25 A. Exceeding it leads to burnout of the wire.
- The yellow cable in the pinout is also a plus and will be used to highlight the part.
- The black wire responsible for power is negative. One end goes to the device, and the other to the battery.
