Checking and removing brake signals

If both brake lights fail at the same time, the brake light switch is usually the cause. It is located at the top of the brake pedal in the driver's footwell. When the brake pedal is depressed, the push pin comes out of the switch housing, the switch contacts close, in turn completing the circuit leading to the brake signals. When the pedal is released, the pin returns to its original place, the lamps go out.

Sequence of work

1. Remove the upholstery in the driver's footwell.

2. Remove the switch connector.

3. Check the switch with an ohmmeter. When you press the brake pedal, its contacts (4 mm) should complete the circuit.

4. There is one more additional contact in the switch (opening). The closing contacts near it are smaller (2.5 mm). When the brake pedal is released, the circuit is opened due to the break contact.

5. To remove the switch's plastic buffer, press it with a screwdriver.

6. Turn the switch and remove.

7. Before installing the push pin switch with force (about 50 N) pull to the end.

8. Press a brake pedal and establish the switch.

9. Screw the switch until it clicks.

10. Release the brake pedal. The move will set itself.

11. Check node operation.
