Volvo-modeller feilkoden gjelder for
Gjelder følgende modeller:
1 modellXC90 (2003–)
Hva betyr feilkoden?
The steering angle sensor control module (SAS) sends data to the brake control module (BCM) in small packets, and each packet carries an ID number. The code is set when the BCM receives an ID number it does not expect.
Mulige årsaker
- Interference or intermittent breaks on the CAN network
- Internal fault in the steering angle sensor control module (SAS)
Hva du kan gjøre
- 1If the code was set during programming of the brake control module, clear it and check that it does not return
- 2Read codes in the central electronic module and troubleshoot any codes there first
- 3Check the connectors at the brake control module and the steering angle sensor for contact resistance and oxidation, and keep the wiring away from sources of interference such as mobile phones
- 4If no fault is found, have a workshop replace the steering angle sensor
- 5The brake and stability systems are safety-critical, so have a workshop carry out any work on the modules
