Clutch Switch Circuit

CRUISE CONTROL SYSTEM: Clutch Switch Circuit

Clutch Switch Circuit

DESCRIPTION

Clutch switch circuit inspection is necessary for manual transaxle vehicles.
When the clutch pedal is released, the ECM receives positive (+) battery voltage through the IG1 relay and GAUGE fuse. While depressing the clutch pedal, the clutch switch assembly sends a signal to terminal D of the ECM. The ECM cancels cruise control drive when terminal D receives the signal.
