What does this fault code mean?
The parking assistance camera module (PAC) checks its own setup against the car's setup, which the central electronic module (CEM) holds. The fault is set when the two do not match. The fault can come from an incorrect configuration file in the car.
Possible causes
- The car's configuration file is incorrect
What you can do
- 1Has the parking assistance camera module (PAC) been replaced or moved from another car recently? Tell the workshop, since it then needs to be configured for your particular car
- 2Read out and erase the fault code, test drive with reverse gear engaged and see whether it comes back
- 3Have a workshop check the car's configuration data and fit the parking assistance camera module (PAC) correctly if it does not suit the car
Symptoms you may notice1
- Front and rear park assist does not work
