Co oznacza ten kod błędu?
The SUM continuously gets yaw and sideways-acceleration data from the BCM over the CAN network, and here it has received invalid or incorrect values. The code is event-driven and indicates information rather than a fault in the SUM. It disappears when the conditions no longer apply.
Możliwe przyczyny
- Fault in the brake control module (BCM)
- Fault in the CAN network
Co możesz zrobić
- 1If you have a diagnostic tool, read the fault codes in the brake control module (BCM), since it sends the incorrect data
- 2Deal with any fault codes in the brake control module first, then check whether this code is still present
- 3If there are also communication faults in the SUM, check the fault codes in the central electronic module (CEM)
- 4Inspect the connectors and wiring in the CAN network for loose connections, chafing and pinch damage
- 5The fault concerns the signals from the brake control module: have a workshop check the brake system and do not work on it yourself
Objawy, które możesz zauważyć2
