Was bedeutet der Fehlercode?
The fault code means that the control module storing the fault has lost its link to the tailgate module (POT), or the link is disturbed. The automatic opening and closing of the tailgate or boot lid may then stop working. The fault concerns the network rather than one individual control module.
Mögliche Ursachen
- The POT receives no supply voltage
- Broken ground lead to the POT
- Poor contact in the connections
- Open or shorted CAN wiring
- A module not intended for the car, such as a used unit with other software or hardware
Was Sie tun können
- 1Switch the ignition on and try the automatic function to see whether anything happens
- 2Confirm the POT fuse in the rear relay and fuse centre is intact
- 3Check the connections between the rear relay and fuse centre and the POT for contact resistance, oxidation and damage
- 4Check the ground wire for breaks or shorts to voltage, and the ground point for play. If the fault returns, have a workshop check the CAN wiring
