1.GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2.
2.CHECK DTC
1. Check DTC for Intelligent Key unit and BCM.
2. Perform the following procedure if DTC is displayed.
- Erase DTC.
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
3. Check related service bulletins for information.
Is any symptom described and any DTC detected?

Symptom is described, DTC is not displayed>>GO TO 4.
Symptom is not described, DTC is displayed>>GO TO 5.
3.CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in "DATA MONITOR" mode and check real-time diagnosis results.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5.
4.CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in "DATA MONITOR " mode and check real-time diagnosis results.

If two or more DTCs are detected, refer to SEC-70, "DTC Inspection Priority Chart" (Intelligent Key unit),
SEC-70, "DTC Inspection Priority Chart" (BCM) and determine trouble diagnosis order.
Is DTC detected?
YES >> GO TO 8.
NO >> Refer to GI-51, "Intermittent Incident".
6.PERFORM BASIC INSPECTION
Perform Basic Inspection. Refer to SEC-5, "Work Flow".
>> GO TO 7.

ment.
B
3. Check DTC. If DTC is displayed, erase it.
>> GO TO 10.
C
10.FINAL CHECK
When DTC was detected in step 9, perform DTC Confirmation Procedure or Component Function Check
again, and then check that the malfunctions have been fully repaired. D
When symptom was described by the customer, refer to the confirmed symptom in step 3 or 4, and check that
