INSPECT ECM (CLSW TERMINAL)
INSPECT CLUTCH SWITCH
CHECK HARNESS AND CONNECTOR (ECM - CLUTCH SWITCH)
CRUISE CONTROL SYSTEM (for 2AD-FHV) - 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 LH-IG fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal CLSW of the ECM. The ECM cancels cruise control drive when terminal CLSW receives the signal.
