Clutch Switch Circuit

CLUTCH SWITCH CIRCUIT

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 ECU-IG 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.
