INSPECTION PROCEDURE 24
Malfunction of the clutch switch system
When the clutch pedal is depressed, the clutch switch sends a signal to the
engine-ECU, and the engine-ECU controls the fuel injection properly based on
this signal. Due to this, engine speed fluctuation is reduced at shifting.
Check the clutch switch. (Refer to
P.13A-109.)
OK
Measure at the clutch switch connector
B-68.
Disconnect the connector, and
measure at the harness side.
