Co oznacza ten kod błędu?
The parking assistance camera module (PAC) communicates all the time with the trailer module (TRM). The fault is set when communication with the TRM is disturbed or missing. The fault can come from a missing or broken voltage supply or earth to the TRM, contact resistance, broken or short-circuited CAN wires, or a TRM that is not intended for the car.
Możliwe przyczyny
- No power reaches the trailer module (TRM)
- Open circuit in the earth cable to the trailer module (TRM)
- Contact resistance in the connections
- Open circuit or short circuit in the CAN wires
- The trailer module (TRM) does not match this car, such as a second-hand unit with other software or hardware
Co możesz zrobić
- 1Check that the fuses are intact and that the earth points are firmly fixed and not oxidised
- 2Erase the fault code and test drive the car to see whether it comes back
- 3Has the trailer module been replaced recently or is it used? Tell the workshop, since it then needs the right software
- 4Have a workshop check the power supply, the earth and the CAN wires to the trailer module, and download new software if needed
