What does this fault code mean?
The fault concerns the control module's watchdog function and microprocessor, that is the part that monitors whether the control module works as it should. The fault is set when the control module detects a problem with the software or that internal components do not work. It is caused by missing or wrong software, or by a damaged parking assistance camera module (PAC), and the camera does not work while the fault remains.
Possible causes
- Software is missing or wrong in the parking assistance camera module (PAC)
- Damaged parking assistance camera module (PAC)
What you can do
- 1Erase the fault code and test drive the car to see whether it comes back
- 2Have a workshop download new software into the parking assistance camera module (PAC)
- 3The parking camera is replaced only if new software does not help. A workshop does that
Symptoms you may notice1
- The parking camera does not work
