Hva betyr feilkoden?
The power seat control module (PSM) communicates with other control modules over the CAN network, and here it has detected a general fault on the medium speed network (MS-CAN). The fault can be caused by a short or open circuit in the CAN wiring, by another control module on the same part of the network sending faulty messages, or by a damaged seat control module.
Mulige årsaker
- Short-circuit in the CAN wiring
- Open circuit in the CAN wiring
- Internal fault in another control module on the same part of the CAN network
- Damaged power seat control module (PSM)
Hva du kan gjøre
- 1Read the codes in the car first. Communication faults in other control modules can give the same code, so they should be fixed first
- 2With the battery negative lead disconnected, check the CAN wires with a multimeter for open circuits and shorts to ground or voltage
- 3Check the connectors in the CAN network for loose, oxidised or damp connections
- 4If another control module on the network is sending faulty messages, have a workshop locate it with diagnostic equipment
- 5Have a workshop replace the seat control module only if fault-tracing shows that it is the faulty part
Symptomer du kan merke4
- Remote operation does not work
- Automatic seat and outer mirror adjustment does not work
- Front seat, power seat adjustment and folding do not work
- Automatic adjustment to a stored position (memory) does not work
Hva feilen kan påvirke2
- The control module switches itself off ("bus-off")
- It stays off until the power supply is interrupted and reconnected, then it makes a new attempt to communicate
