When you press the brake pedal, the spring presses on the drive rod (pusher) switch in the switch direction. This closes the contacts in the switch and the electrical circuit of the brake lights. When the brake pedal is released, the pedal neck pushes the drive rod to its original position, and the brake light goes out. In addition, the combination switch transmits appropriate signals to the anti-lock system control device, so the correct operation and adjustment of the switch is very important.
Pedal bracket switch: 1 - clamp, 2 - brake light switch F and brake pedal position sensor F47, 3 - clutch pedal position sensor F36.
1. Remove the cover in the driver's footwell.
2. Remove the connector from the brake light switch.
3. Use a piece of wire or a paper clip to bridge the contacts in the connector.
4. If the brake lights then come on, the switch is faulty. Replace switch. This switch can only be installed once, i.e. if the switch has been removed, it must be replaced. To unfasten and remove the switch, turn it slightly to the left.
5. Pull the pusher completely out of the switch to be installed by hand.
6. When installing the switch, the pedals must be in their original position.
7. Insert the circuit breaker into the receiving holes of the bracket. Locking tabs 1 and 2 are inserted into the recesses intended for them.
Stop signal switch
8. The pusher is set automatically during the insertion of the circuit breaker.
9. Fix the switch in the bracket by turning it 45' to the right (clockwise). In this case, a dead fit of the switch must be ensured.
10. Connect the connector to the switch.
11. Check switch operation. The brake light should come on even when you lightly press the pedal.
12. If everything is in order, mount the cover in the footwell.
