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:
- *1: for 1GR-FE
- *2: for 1VD-FTV
