DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.

>> GO TO 2.

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

>> Proceed to

ECK-287, "Diagnosis Procedure"

.

NO

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B

Perform component function check. Refer to

ECK-286, "Component Function Check"

.

NOTE:

(Clutch pedal position switch circuit is open or
shorted.)

• Clutch interlock switch
• Clutch pedal position switch
• Incorrect clutch interlock switch installation
• Incorrect clutch pedal position switch installation

B)
