Co oznacza ten kod błędu?
The CEM shares the LIN bus with the start lock antenna (IAU) and the steering column lock module (SCL). The fault is stored when messages from the CEM never reach the bus, so the bus has effectively stopped working.
Możliwe przyczyny
- The LIN bus is short-circuited to voltage or earth
- Damaged start lock antenna unit (IAU)
- Damaged steering column lock control module (SCL)
Co możesz zrobić
- 1Check that the fuses are intact and that the battery has sufficient voltage
- 2Check the LIN wire for chafing, pinch damage and places where it may have touched voltage or earth
- 3Disconnect the connector at the start lock antenna unit and see whether the fault clears, which would point to that unit
- 4If no cause is found in the wiring, have a workshop with diagnostic equipment check the steering lock and the antenna unit
Objawy, które możesz zauważyć3
- The engine does not start, or the starter does not turn over
- When starting is attempted there is either a clicking sound or no sound at all
- The steering lock does not work
