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 |
Fault code 1C "clutch switch" is stored if the signal is not plausible. Cruise control is deactivated as a result.
