Most of the vehicle's electrical circuits are protected by fuses
Electric motors of gear motors (windshield wipers, rear door glass, headlights - if installed) are protected by automatic bimetallic reusable fuses
The power supply circuit of the injection system (VAZ-21214 engine) is protected by a fuse made of a wire with a core of reduced cross-section (1 mm 2 ).
The circuits for charging the battery, ignition (VAZ-21213 engine), engine start, and the "generator - ignition switch - fuse box" circuit are not protected.
Powerful consumers (starter, headlights, electric motors of cooling system fans, electric fuel pump, etc.) are connected via a relay.
The fuses are grouped in two fuse boxes located on the left under the instrument panel.
The fuse ratings and the circuits they protect are shown in the table.
The injection system fuses (VAZ-21214 engine) are located in a separate block on the left side panel under the instrument panel.
A 30 A fuse protects the power supply circuit of the radiator electric fans, and three 15 A fuses protect the electric fuel pump, control unit (constant power input) and the main relay circuits of the injection system, respectively.
Replacing fuses, removing the fuse box
Disconnect the "negative" wire from the battery.
Pull the latch located on top of the main fuse box cover to remove the cover.
Remove the cover of the additional fuse box in the same way.
Replacing fuse.
To remove the fuse boxes, use an "8" head to unscrew the two nuts
Remove the main and additional blocks from the studs.
Before replacing the fuse boxes, mark the wires and disconnect them
Install new fuse boxes in the reverse order
Removing the relay box
To the right of the steering column, under the instrument panel, there is a block of three identical relays of the 113.3747-10 type, controlling the switching on of: low beam headlights, high beam headlights and heating of the rear door glass.
Disconnect the negative wire from the battery.
To remove the relay, disconnect the socket.
After unscrewing the screw with a Phillips screwdriver,…
Removing the relay.
The starter and ignition relays are secured under the additional fuse box (on a car with an injection engine, they are attached to the injection system relay bracket).
Using a Phillips screwdriver, unscrew the screw securing both relays
After removing the relay, disconnect the pads
Install the relays in the reverse order
Since all the relays are of the same type, if one of them fails, you can temporarily connect its pad to another relay.
For example, if the starter relay fails, its pad can be connected to the rear door glass heating relay.
Replacing the injection engine control system fuses
Disconnect the negative battery cable.
To access the fuses and diagnostic connector of the engine management system, use a Phillips screwdriver to unscrew the two screws in the passenger compartment that secure the casing to the trim of the front left side of the body.
Remove the casing.
Remove the fuse.
The fuse of the electric fans circuit, located on the block at the back, has a rating of 30 A (green), three other fuses with a rating of 15 A (blue) protect the circuits of the main relay, controller power supply and fuel pump.
To remove the fuse box, use the head "on the 8" unscrew the two nuts securing the unit and remove it.
Install the fuse box in the reverse order
Next to the fuse box is the diagnostic connector
