8. DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE:
The Diagnostic Procedure described based on open circuit inspection. A short circuit inspection is also
required for the circuit check in the Diagnostic Procedure.
Is malfunctioning part detected?
YES >> GO TO 9
NO >> Check voltage of related BCM terminals using CONSULT-III.
9. REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it.
>> GO TO 10
10. FINAL CHECK
When DTC was detected in step 2, perform DTC Confirmation Procedure or Component Function Check
again, and then check that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that
the symptom is not detected.
Does the symptom reappear?
YES (DTC is detected)>>GO TO 8
YES (Symptom remains)>>GO TO 6
NO >>INSPECTION END
