Was bedeutet der Fehlercode?

The engine control module (ECM) receives brake pedal status from the brake control module (BCM) over CAN, including from a cancel switch fitted to cars with adaptive cruise control. The code is set when the signal from that cancel switch is judged to be faulty. The code can also be set during a CAN communication fault, in which case it appears together with other codes. Although the code is titled brake pedal switch circuit, it concerns the cancel switch.

Mögliche Ursachen

Fault in the brake control module (BCM), which should be checked first
Fault on the CAN network

Was Sie tun können

1Read the codes in the brake control module and the engine control module. Troubleshoot the CAN-related codes first
2Check that the fuses are intact
3Check the CAN connectors between the engine control module and the brake control module for oxidation and loose contacts
4Use a multimeter to check that the CAN wires have no break or short to ground or supply voltage
5Do not work on the braking system yourself. If it returns: have a workshop check the brake module and the cancel switch
