Clutch module

On vehicles with manual gearboxes, the clutch module at the clutch pedal picks up the clutch position:

• Clutch pressed: clutch switch open
• Clutch not pressed: clutch switch closed.

The clutch module comprises the clutch switch and evaluation electronics.

Among other things, the Digital Engine Electronics (DME) has a signal line. When the clutch pedal is not pressed, the clutch module delivers 12 Volts and when the clutch pedal is pressed it delivers 0 Volts.

The clutch module is used as an input signal for the automatic engine start-stop. Two states are picked up:

• 10 percent operated
• 90 percent operated.
