What does this fault code mean?
The anti-pinch sensor on the right side of the tailgate keeps showing a signal well after the tailgate has started to open, which the tailgate control module (POT) records as a fault. The circuit to the sensor has a short circuit, and that is what causes the fault.
Possible causes
