Was bedeutet der Fehlercode?
The code means the brake pedal position sensor signal is too low. On cars of model year 1999 to 2001 the signal is measured directly at the sensor. On model year 2002 the ECM instead takes the brake pedal position from the brake control module (BCM) over the CAN network. The brake pedal sensor belongs to the brake system, so the fault should be dealt with.
Mögliche Ursachen
- Signal cable short-circuited to ground
- On model year 2002: a fault in the CAN communication between the BCM and the ECM
Was Sie tun können
- 1Read the fault codes in the brake control module (BCM) and in the ECM. If the BCM has codes that point to the brake pedal sensor, deal with those first
- 2If you have a diagnostic tool: read the fault status. It shows whether the fault is permanent or intermittent, and whether other codes are stored
- 3Use a multimeter to check that the signal cable from the sensor is not shorted to ground (body). Check the wiring and connectors: are they secure, and is there oxidation
- 4The brake system is safety-critical. If the fault remains, have a workshop check it, and do not drive with a safety fault in the brakes
Symptome, die Sie bemerken können2
- Electronic throttle system (ETS) warning lamp lights
- Cruise control does not function at all
Was der Fehler beeinflussen kann2
- Cruise control is off for the driving cycle in which the fault was detected
- At the next start the function is available, if the fault is no longer present
