DESCRIPTION
Clutch switch circuit inspection is necessary for manual transmission vehicles.
When the clutch pedal is released, the ECM receives the positive (+) battery voltage through the ECU-IG NO. 2 fuse and ignition switch. While the clutch pedal is depressed, the clutch switch assembly sends a signal to terminal D of the ECM. The ECM cancels cruise control when terminal D receives the signal (voltage of below 1 V).
