INSPECT CLUTCH SWITCH ASSEMBLY
CHECK HARNESS AND CONNECTOR (ECM - CLUTCH SWITCH ASSEMBLY)
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.
