Was bedeutet der Fehlercode?
Although the code is titled signal too high, it concerns a message from the CEM about the accelerator pedal sensor's analog signal or about CAN communication. The ECM receives the message and sets the code, while the fault tracing is done in the CEM.
Mögliche Ursachen
- The cause is sought in the central electronic module (CEM)
Was Sie tun können
- 1Read and deal first with the CEM fault codes, as this code cannot be cleared before then
- 2If you have a diagnostic tool: read the accelerator pedal value in live data with the engine running, while the pedal is pressed slowly and released
- 3If the fault remains once the CEM is remedied, have a workshop with diagnostic equipment decide where the fault sits
- 4The accelerator pedal can stop working when the brake is pressed, which is a safety matter. Have a workshop check it at once
Symptome, die Sie bemerken können2
- Poor accelerator pedal response
- Cruise control does not function at all
Was der Fehler beeinflussen kann1
- The accelerator pedal stops working when the brake is pressed
