DTC CONFIRMATION PROCEDURE

1.

PERFORM COMPONENT FUNCTION CHECK

1.

Turn ignition ON, and wait for 5 seconds or more.

2.

Perform “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT.

Is the inspection result normal?

YES-1 >> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

YES-2 >> Confirmation after repair: INSPECTION END
NO

>> Proceed to 

CHG-20, "Diagnosis Procedure"
