Checking Installation, Brake Light Switch, And Brake Pedal Position Switch (Cont.)
After replacing the stop lamp switch or the brake pedal position switch, it is necessary to check that it is correctly installed.
The instructions below must be carried out in the correct order:
- Start the engine.
- Release the brake pedal if it is depressed.
- Click on the VCT2000 (Volvo Scan Tool) symbol.
- Slowly press down the brake pedal.
If the symbols light up green, the connectors are correctly installed.
If any of the symbols light up red, this may be due to the brake pedal being depressed too quickly or that the connector is not correctly installed.
Try again by slowly depressing the brake pedal.
If any of the symbols still light up red after 5 attempts, this indicates that the connector is not correctly installed.
If no fault is found in the brake light switch or in the brake pedal switch, the fault may be due to the pressure sensor in the Brake control module (BCM). Check therefore any diagnostic trouble codes in the Brake control module (BCM).
