Was bedeutet der Fehlercode?

Although the code is named signal missing, it can also mean that the clutch pedal sensor reports a wrong value, or that CAN communication is faulty. The engine control module (ECM) gets an error report from the central electronic module (CEM) via CAN and stores the code. There is no separate troubleshooting, and the code cannot be erased until the fault in the CEM is remedied.

Mögliche Ursachen

The signal from the clutch pedal sensor is missing or faulty, according to the central electronic module (CEM)
Fault in the communication on the CAN network

Was Sie tun können

1First read off the fault codes in the central electronic module (CEM) and remedy the cause there, as this code cannot be erased before then
2Once the fault in the CEM is remedied and erased, you can erase this code too
3Check the connector at the clutch pedal sensor and the wiring to it for loose contacts, oxidation and chafed areas
4If you have a diagnostic tool: follow the clutch pedal position in live data and check that the value changes smoothly when the pedal is pressed and released
