CRUISE CONTROL SYSTEM - Clutch Switch Circuit


DESCRIPTION

When the clutch pedal is released, the ECM receives positive (+) battery voltage through the LH-IG fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal D*1 or CLSW*2 of the ECM. The ECM cancels cruise control when terminal D*1 or CLSW*2 receives the signal.
HINT:
