2.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A
1. Turn ignition switch ON.
2. Fully depress clutch pedal.
3. Fully release clutch pedal.
4. Repeat steps 2 and 3 for five times.
5. Check DTC.
Is DTC detected?
YES - Go to "Diagnosis Procedure".
NO - GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B
Perform component function check. Refer to "Component Function Check".
NOTE:
Use component function check to check the overall function of the clutch switch circuit. During this check, a DTC might not be confirmed.
Is the inspection result normal?
YES - INSPECTION END
NO - Go to "Diagnosis Procedure".
Component Function Check
