Clutch Switch Circuit

CRUISE CONTROL: CRUISE CONTROL SYSTEM: Clutch Switch Circuit
- Clutch Switch Circuit

DESCRIPTION

Clutch switch circuit inspection is necessary for M/T vehicles.

When the clutch pedal is released, the ECM receives positive (+) battery voltage through the ECU-IG No. 1 fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal D of the ECM. The ECM cancels cruise control when terminal D receives the signal.
