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
