A switch is fitted on the clutch pedal for the purpose of registering clutch operation on vehicles with manual transmission.
The clutch switch switches to ground. The plausibility of the signal is checked together with cruise control.
The following table shows how the signal behaves:
|
Clutch switch is |
Clutch operated |
Open |
Clutch not operated |
Closed |
If the signal is not plausible a fault code will be stored in the fault code memory of the DME control unit. Cruise control is deactivated as a result.
