Co oznacza ten kod błędu?
The brake control module (BCM) receives brake pressure information from a pressure sensor built into the hydraulic unit. The code is set when the signal from that sensor is faulty.
Możliwe przyczyny
- Damaged wire or connection to the sensor
- Brake pedal position sensor has come loose from its connection
- Damaged brake pedal position sensor
Co możesz zrobić
- 1Check the wiring and connections at the brake pedal position sensor for loose contacts and damage
- 2Make sure the brake pedal position sensor is firmly seated
- 3If the fault only appears now and then, check whether the brake pressure changes during a drive, as this points to an earlier, temporary fault
- 4If the fault returns, a workshop needs to replace the brake control module
- 5The brake system is safety-critical, so have a workshop carry out all work on the sensors and the module
Objawy, które możesz zauważyć3
- Traction and stability warning indication shows a fault or no indication
- Traction control does not work
- Stability function does not work
Na co może wpływać usterka2
- Traction control and stability control are switched off
