What does this fault code mean?
The tailgate control module (POT) receives information from the central electronic module (CEM) over CAN, but the quality of that information is lower than the POT accepts. The fault lies in the control module that sends the information, so the tailgate's functions may be limited.
Possible causes
- Fault in the control module that sends the information
What you can do
- 1Read off and clear the fault code, test drive and see whether it comes back
- 2Check that the fuses for the tailgate are intact
- 3If you have a diagnostic tool: check whether the central electronic module (CEM) has its own fault codes and start with those
- 4Have a workshop trace the control module that sends the information, since the fault is there
Symptoms you may notice4
- The tailgate is hard to open
- The tailgate is hard to close
- The central locking for the tailgate does not work
- Automatic opening and closing of the tailgate does not work
What the fault can affect1
- Limited function in the tailgate control module (POT)
