Was bedeutet der Fehlercode?

The value sent by the central electronic module (CEM) for the clutch pedal position is below the permitted range. The engine control module checks that the signal is reasonable and sets the code when it is not. The fault may lie in the sensor, in the signal wire or in the CEM.

Mögliche Ursachen

Damaged clutch pedal position sensor
Signal wire shorted to earth
Open circuit in the wire
The fault may lie in the central electronic module (CEM)

Was Sie tun können

1Read the engine control module fault codes. If any of ECM-U012088, ECM-U000188, ECM-U1A1400, ECM-U000108 or ECM-U000100 is stored, investigate it first
2If ECM-U010482, ECM-P193582, ECM-P080582 or ECM-U042600 is stored, investigate it first, as it most likely leads to the root cause
3Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
4Use a multimeter to check that the wire from the position sensor has no contact with earth (the body) and has no break
5Check that the connectors at the position sensor are firmly seated and free from oxidation
6Have a workshop investigate the central electronic module (CEM) if the fault remains after these checks, as the code may originate there

Symptome, die Sie bemerken können1

Was der Fehler beeinflussen kann1
