Co oznacza ten kod błędu?

The engine control module (ECM) has been alerted by the central electronic module (CEM) saying that the accelerator pedal signal is invalid. The fault may lie in the accelerator pedal signal or in the CAN communication between CEM and ECM. This is a follow-on code: the root fault is in CEM, and this code can only be erased once the fault there has been fixed.

Możliwe przyczyny

Fault in the central electronic module (CEM)
Fault in the CAN communication between CEM and the engine control module

Co możesz zrobić

1Read the fault codes in the central electronic module (CEM) first, since the root fault is there
2Troubleshoot and fix the CEM faults as needed, starting with the fuses and connectors that belong to it
3Erase the code in the engine control module only after the CEM faults are gone, then road test the car to check that it does not return
4If you have a diagnostic tool, read the accelerator pedal position in live data while pressing and releasing the pedal, and check that the value follows the movement smoothly
