Inspection Procedure 2: When the Clutch Pedal is Depressed, cruise Control is not Cancelled. <M/T>












OPERATION



  • Engine-ECU terminal No.112 monitors the clutch switch state.
  • The clutch switch turns ON/OFF when the clutch pedal is depressed/released, and the input signal to the engine-ECU changes. According to this change, the engine-ECU judges the clutch switch status.
