Protected components

1 (50 A) – ABS .

2 (40 A) – constant power supply to devices with the ignition off .

3 (10 A) – fuel pump .
If, when the ignition is turned on, the fuel pump does not work (you cannot hear the sound of its operation), check relay E, this fuse and the voltage on it. If there is voltage at the fuse, get to the fuel pump and check if voltage is supplied to it when the ignition is turned on. If it does, most likely you need to change the fuel pump to a new one. When installing a new one, also change the filter of the pump module. If the pump does not have voltage, most likely the matter is in the wiring, or the fuel pump circuit breaker (for example, in the installed alarm). Wires could fray under seats, in bundles, or poor contact at joints / twists.

4 (10 A) – ECU power supply, fuel pump relay coil, ABS unit, generator winding at start, terminal B from the ignition coils, speed sensor .

5 (10 A) – reserve .

6 (20 A) – stove fan .
If the stove stops working, check this fuse, the motor of its fan by applying a voltage of 12 V to it, as well as the handle and its drive cable going to the heater tap. If the stove is blowing cold, this cable could fly off, it is located on the driver’s side near the center console under the dashboard. If the stove speed is not adjustable, also check the C relay under the hood. There may also be an airlock.

To remove air from the system, drive up the hill in front of the top, open the cover of the expansion tank and gas. On a hot engine, be careful when opening the reservoir cap. Also, the matter may be in the heater radiator or clogging of the air intake pipes.

7 (15 A) – rear window heating .

If the heating stops working, check the fuse, as well as the contacts in its socket. If the contact is poor, you can bend the terminals.
In many models, due to the absence of a relay in the rear window heating circuit, the power button has a large current load, so it often fails. Check its contacts and if it ceases to be fixed in the pressed position, replace it with a new button. You can get to it by removing the dashboard trim or pulling out the radio tape recorder. It is best to install a relay, thereby relieving the button. In some models, this button has a relay C under the hood, check it.

Also check the threads of the heating elements for breaks, breaks of the threads can be sealed with a special glue containing metals. It can also be in the terminals at the edges of the glass, in a poor grounding contact and in the wiring from the rear window to the button.

8 (10 A) – right headlight, high beam .
9 (10 A) – left headlight, high beam .
If your main beam stopped burning when you turn on this mode, check these fuses, fuse F18, contacts in their sockets, the lamps in the headlights themselves (one or two could burn out at once), relay H in the engine compartment and its contacts, the steering column switch and its contacts. The contact in the switch connector is often lost, disconnect it and check the condition of the contacts, clean and bend if necessary. Also check the wires coming from the headlights for breaks, short circuits and insulation damage. The minus on the relay contact H may also disappear due to oxidation or burnout of the track in the mounting block.

To replace the lamp in the headlight, disconnect its connector with wires, remove the rubber cover (boot) from the side of the engine compartment, squeeze the “antennae” of the lamp clip and take it out. When installing a new lamp, do not touch the glass part of the lamp with your hands. handprints will darken when turned on. Lamps in the headlights are installed two-filament, one lamp for low and high beam, for dimensions in the headlights there are separate lamps of a smaller size.

F10 (10 A) – right headlight, low beam .
F11 (10 A) – left headlight, low beam .
Same as high beam, except F18.

12 (10 A) – right side, size lamps .

13 (10 A) – left side, size lamps, license plate lighting lamps .
If your side light is missing, check these fuses and relays I, as well as their contacts. Check the health of the lamps in the headlights, the contacts of the connectors and the wiring.

14 (10 A) – air conditioning compressor clutch (if available) .
If your air conditioner does not work, and the clutch does not move when it is turned on, check this fuse and relay J, as well as the power button and its contacts, wiring. The movement of the working clutch should be heard by the characteristic sound when the air conditioner is turned on. If the clutch works, but cold air does not flow, most likely the system needs to be filled with freon.

Do not forget that in winter it is necessary to periodically turn on the air conditioner in a warm place – a box or a car wash, so that the seals are lubricated and remain in good condition after winter.

15 (30 A) – radiator cooling fan .
If your radiator fan stops turning on, check relays A, B, G, this fuse and their contacts. The fan is connected via a thermal switch, which is installed on the radiator, 2 wires fit to it. Take them out and close them together, when the ignition is on, the fan should start working. If it works in this position, most likely it is a malfunction of the thermal switch, replace it.

If the fan is not working, there is a wiring or a defective fan motor. The motor can be tested by applying voltage directly to it from the battery. Also check the coolant level, the serviceability of the temperature sensor and the thermostat.

16 (10 A) – reserve .

17 (10 A) – sound signal .
If there is no sound when you press the button on the steering wheel, check this fuse and relay F, their contacts. The signal is located in the left fender, on the driver’s side, to access it you need to remove the left wheel arch liner, the signal is located behind the fog lamp. You may need to remove the left front wheel for convenience. Ring the wires suitable for it, if there is voltage on them, most likely the signal itself is faulty, disassemble or replace it. If there is no voltage, the point is in the wiring, steering contacts or the ignition switch.

18 (20 A) – power supply of the head light relay, high beam switch .
For problems with high beam, see information on F8, F9.

19 (15 A) – constant power supply to the ECU, coil of the air conditioning compressor clutch relay, coil of the main relay, coil of two radiator fan relays, camshaft position and oxygen concentration sensors, exhaust gas recirculation and adsorber valves, injectors, fuel pump relay power .
If there is a problem with the listed devices, also check the main relay B.

20 (15 A) – fog lights .
If your “fog lights” stopped working, check the relay D under the hood, this fuse and their contacts, as well as the lamps in the headlights, their connectors, wiring and the power button.

21 (15 A) – reserve .

Fuse designation

1 (10 A) – dashboard, sensors and warning lamps, immobilizer, clock, alarm .
If you have stopped showing the sensors on the dashboard and its backlight disappeared, check the panel connector on the back of it, it may have popped out or the contacts have oxidized. Also check the wires and connectors on the back of the mounting block for this fuse.

When the ignition is turned on, the immobilizer icon on the panel lights up – this means that it is looking for a chip key. If the key is found successfully, the lamp goes out and you can start the car. To add a new key to the system, you need to flash / teach the ECU to work with the new key. If you are not familiar with electrics, it is better to contact a car service. If the car is not on the move, you can find and call an on-site electrician.

2 (10 A) – airbag (if available) .

3 (25 A) – power windows .
If the window regulator of one door stops working, check the integrity of the wires at the bend when opening the door (and between the body and the door), the control button and its contacts. Also, the matter may be in the window regulator mechanism. To get to it, remove the door trim. Check the serviceability of the motor by applying a voltage of 12 V to it, the absence of skewing of the glass in the guides, the integrity of the gear and cable (if the window regulator is of a cable type).

4 (10 A) – direction indicators, turn signal lamps on the dashboard .
If your turn signals stop working, check the repeater relay B, it can click when the turns are turned on, but it does not work. Replace with a new relay, also check the contacts in the fuse sockets and its serviceability. The relay in some models may not be located in the mounting block, but under the torpedo on the driver’s side. If the matter is not in the relay / fuse, then most likely in the steering column switch, check its contacts and wires.

5 (15 A) – brake lights .

If one of the brake lights does not work, check its lamp, contacts in the connector and wiring. To replace the bulbs, you need to remove the headlight. To do this, unscrew the 2 headlight mounts with a screwdriver from the trunk side, opening the tailgate and the headlight will get out, opening access to the lamps. If both brake lights are off, check the brake pedal switch, wiring and lamps. Cheap lamps can burn out often, replace them with more expensive ones.

If the contacts in the switch or the wiring are closed, the brake light lamps may remain on continuously, without pressing the brake pedal. In this case, remove the short circuit.
There may also be an open or short circuit in the wiring from the headlights to the trunk.

6 (10 A) – radio tape recorder .
Clarion standard radio. Usually, the radio is turned on only when the key is turned to 1 or 2 position (2 – ignition). If your radio stops turning on when you turn on the ignition, check this fuse and the contacts in its socket. Measure the voltage at the radio connector by disconnecting it.

If the 12 V voltage comes there and the connector contacts are working, most likely the case is inside the radio tape recorder itself – either its power switch has broken, or the contact inside on the board has disappeared, or one of its nodes has failed. If there is no voltage at the connector, check the wiring to the fuse, as well as the presence of voltage on it.

7 (20 A) – cigarette lighter .

If the cigarette lighter stops working, check the fuse first. Due to the connection of different connectors of devices to the cigarette lighter at different angles, a short circuit of the contacts can occur in it, because of this, the fuse burns out. If you have an additional 12V connector, plug in the devices there. Also check the wiring from the cigarette lighter to the fuse.

8 (15 A) – windshield wiper .
If the “wipers” do not work in any position, check the fuse and contacts in its socket, relay A in the same mounting block, the steering column switch and its contacts. Apply 12V to the cleaner motor and check if it works. If it fails, replace it with a new one. Inspect its brushes, clean them or replace with new ones if contact is poor. Also check the wires from the engine to the steering column switch, from the relay to ground, from the fuse to the relay, and from the fuse to the power source.

If the “wipers” do not work only in intermittent mode, most likely it is a relay, a poor ground contact to the body, or an engine malfunction.
Also check the wiper mechanism, trapezoid and the tightness of the wiper mounting nuts.

9 (15 A) – rear window cleaner, front and rear washers, reversing lamp .

If your windshield and rear window washer does not work, check the fluid level in the washer reservoir. Located at the bottom of the right headlight. To get to it, you will most likely need to remove the headlight. In order not to remove the headlight, you can try to crawl up from below with the wheels turned inside out and the right wheel fender liner removed. In the lower part of the tank there are 2 pumps – for the windshield and the rear window.

Apply 12 V voltage directly to one of the pumps, thereby check its serviceability. Another way to check is to swap the terminals for two pumps, because one of the pumps is most likely working. If the pump is faulty, replace it with a new one. If the washer stops working in winter, make sure that an anti-freeze fluid is filled, check the system channels for clogging and freezing of the fluid, also check the nozzles from which fluid enters the glass.
Another thing may be in the steering column switch, check in it the contact responsible for the operation of the washers.

If the rear washer does not work, and the front washer is working and the pumps are working properly, most likely the matter is a break in the fluid supply pipe to the rear door or its connections in the system. The rear washer pipe connections are located in the front bumper, in the tailgate rib and inside the tailgate. If the tube breaks in the area of ​​the rear door, you need to remove the door trim and rear of the passenger compartment for replacement. First, it is better to remove the corrugation between the door and the body, check the integrity of the tube in this place. The broken tube can either be repaired by cutting off the problem area and reconnecting, or replaced with a new one.

If the reversing light does not work, check the lamp and the contacts in its connector. If the lamp is intact, most likely the matter is in the reverse switch, screwed into the gearbox. You can get there from under the hood by removing the air filter. The reverse sensor is screwed into the gearbox from above. The sensor closes the contacts when reverse gear is engaged. If it fails, replace it with a new one.

10 (10 A) – electric side mirrors .

11 (10 A) – immobilizer, audio system, light in the cabin and trunk, open door lamp on the dashboard .
For problems with the immobilizer see F1.

If the interior light is off, check this fuse, its contacts, as well as the lamp and its connector. To do this, disassemble the cover – remove the cover and unscrew the 2 screws. Check if there is voltage to the lamp. Also check the door limit switches and their wires.

12 (15 A) – constant power supply for the alarm, hours .

13 (20 A) – central locking .
If other doors do not open when opening / closing the driver’s office, the case may be in the central locking unit, which is located in the driver’s door. To get to it, you need to remove the trim. Check its connector, contacts and wiring. In case of problems with closing / opening the driver’s door, check the mechanism drive at the lock (with the trim removed). He must move the lock rod and close / open contacts to control locks in other doors.

14 (20 A) – starter traction relay .
If the engine does not start and the starter does not turn, it may be a dead battery, check its voltage. In this case, you can “light” from another battery, charge a dead battery, or buy a new one. If the battery is charged, check the condition of the starter itself. To do this, put the gearshift knob in the neutral position and close the contacts on the starter retractor relay, for example, with a screwdriver. If you do not twist, then most likely the matter is in the starter, its bendix or retractor.

If you have an automatic transmission, and when turning the key, the starter does not turn, try switching the lever to the P and N positions, while trying to start. In this case, most likely the matter is in the selector position sensor.
Also check the ignition switch, the contacts inside it and the wires of the contact group, perhaps due to poor contact when turning the key, the voltage does not reach the starter.

The fuse number 7 is responsible for the operation of the cigarette lighter.
