Was bedeutet der Fehlercode?
The control module verifies the brake pedal sensor and stop lamp switch signals. A fault in either circuit, or in CAN traffic between the BCM and the engine module, sets the code. It shows up with the ignition on and the pedal depressed.
Mögliche Ursachen
- Incorrectly installed stop lamp switch
- Contact resistance or oxidation at the stop lamp switch connections
- Open circuit in the feed to the stop lamp switch
- Open circuit or short to ground or voltage in the signal wire to the stop lamp switch
- Damaged stop lamp switch
- Fault in the brake control module (BCM), which a workshop needs to trace
Was Sie tun können
- 1Fault codes in the BCM and CEM modules come first, since they may be the cause
- 2Check that the fuses are intact. Their locations are shown in the instruction manual or on the fuse box cover
- 3Make sure the stop lamp switch sits properly and that its bracket is intact. Do not adjust its position yourself, as it needs correct setting
- 4Switch off the ignition and check the stop lamp switch connector for contact resistance and oxidation
- 5The brake lights must work. If they do not work when you press the brake, fix the fault before driving, and have a workshop check the signal wire
Symptome, die Sie bemerken können3
- Poor performance and lack of power
- Yellow warning symbol and text message in the display
- Cruise control does not engage
Was der Fehler beeinflussen kann1
- Cruise control is switched off
