Was bedeutet der Fehlercode?
The engine control module (ECM) checks the brake light switch by comparing its signal with the brake pedal position, which the brake control module (BCM) sends over the CAN network. The code is set when the two signals show different brake pedal positions on several occasions. An incorrect or invalid signal from either position switch may be the cause.
Mögliche Ursachen
- Diagnose the cause in the brake control module (BCM)
- Contact resistance or oxidation in the connections to the brake light switch
- Contact resistance or oxidation in the connections to the brake pedal switch
- Break in the signal wire or short to ground
- Damaged brake light switch or brake pedal switch
- Brake light switch incorrectly fitted
Was Sie tun können
- 1Read the codes in the brake control module (BCM) and the central electronic module (CEM) first, and repair them
- 2Check that the brake light switch is fitted correctly and that the brake pedal position sensor is seated properly. Also check that the fuses are intact
- 3Check the connectors of the brake light and brake pedal switches for oxidation, loose contacts and chafed or broken wires
- 4If you have a diagnostic tool, follow the brake pedal positions in live data and check that they agree when the pedal is pressed several times
- 5After the repair, read the code and check that it does not come back when the brakes are used
- 6Do not work on the braking system yourself; have a workshop carry out the checks that need diagnostic equipment
Symptome, die Sie bemerken können5
- Warning symbol and message in the display
- Cruise control does not work at all
- Cruise control does not hold the set speed and disengages
- Autostart does not work
- The engine does not start, either sometimes or always
Was der Fehler beeinflussen kann2
- Autostart is blocked and automatic engine start/stop is switched off
- Cruise control is switched off while the fault is active, or for the drive cycle in which it was detected
