Clutch Pedal Switch
Engine control module (ECM) receives information about the clutch pedal's position in two ways.
Partly from a clutch pedal position sensor which is directly connected to Central electronic module (CEM), and partly from a clutch pedal switch directly connected to the Engine control module (ECM).
The function of the clutch pedal switch is to provide extra safety for the function autostart. In order for the function to be activated, the Engine control module (ECM) must receive signal that indicates pressed down pedal from the clutch pedal switch.
To start without the function autostart it is enough that any of the signals (from clutch pedal position sensor or clutch pedal switch) indicates pressed down pedal.
In its starting position, the clutch pedal switch is open (clutch pedal released). The switch's installation shall be adjusted so that it is closed when the clutch pedal passes 75% of full pedal movement.
The clutch pedal switch is on the pedal box by the clutch pedal.
The engine control module (ECM) can diagnose the clutch pedal switch. The status (position) of the switch can be read using the diagnostic tool.
