Co oznacza ten kod błędu?
The tailgate control module (POT) communicates with the other control modules over the MS-CAN bus. Serious interference has been registered on the network, so communication is blocked and the control module cannot be reached. The cause may be a short or break in the CAN wiring, an internal fault in the POT, or a fault in another control module on the same part of the network.
Możliwe przyczyny
- Short circuit between the CAN wiring
- Open circuit in the CAN wiring
- Internal fault in the tailgate control module (POT)
- Internal fault in another control module on the same part of the CAN network
Co możesz zrobić
- 1Check that the battery is charged and that the fuses for the tailgate are intact
- 2If you have a diagnostic tool: start with the communication fault codes in the other control modules, clear them and test drive
- 3Check that the connectors at the tailgate control module are firmly seated and free from corrosion
- 4Have a workshop with diagnostic equipment measure the CAN network, since it needs readings at several points
- 5Do not replace the central electronic module (CEM) for a CAN fault unless the workshop has found an internal fault in it
