Co oznacza ten kod błędu?
The power steering control module (PSCM) has disconnected itself from the HS-CAN bus (bus-off) because of interference. The cause may be a short or break in the CAN wiring, an internal fault in another control module on the same part of the network, or an internal fault in the control module itself.
Możliwe przyczyny
- Short circuit between the CAN wiring
- Open circuit in the CAN wiring
- Internal fault in another control module on the same part of the CAN network
- Internal fault in the control module
Co możesz zrobić
- 1Clear the fault code and test drive to see whether it comes back
- 2Check that the fuses for the power steering are intact
- 3If you have a diagnostic tool: read off the fault codes in the other control modules and start with those
- 4Check the connectors and wiring at the power steering for loose contacts, chafing and pinch damage
- 5Safety note: steering is safety-critical, so have a workshop decide what needs replacing if the fault remains
