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.
2. Perform the following procedure if DTC is displayed.
- Record DTC and freeze frame data (Print them out with CONSULT-III.)
- 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 displayed>>GO TO 3.
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 MONI TOR” mode and check real time diagnosis results.
Verify relation between the symptom and t he 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 MONI TOR” mode and check real time diagnosis results.
Verify relation between the symptom and t he condition when the symptom is detected.
>> GO TO 6.
5.PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC Confirmation Procedure for the display ed DTC, and then check that DTC is detected again.
At this time, always connect CONSULT-III to the vehicle, and check diagnostic results in real time.
If two or more DTCs are detected, refer to DLK-163, "
DTCInspectionPriorityChart" and determine trouble
diagnosis order.
NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC Confirmation Procedure is not included in Service Manual. This
simplified check procedure is an effective alternat ive though DTC cannot be detected during this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC Confirma-
tion Procedure.
Is DTC detected?
Yes >> GO TO 7.
No >> Refer to GI-38, "
Intermittent Incident".
6.DETECT MALFUNCTIONING SYST EM BY SYMPTOM DIAGNOSIS
Detect malfunctioning system according to SYMPTO M DIAGNOSIS based on the confirmed symptom in step
4, and determine the trouble diagnosis order based on possible causes and symptom.
>> GO TO 7.
7.DETECT MALFUNCTIONING PA RT BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE:
Revision: March 2010 2008 QX56

DLK-8
< BASIC INSPECTION >[WITH INTELLIGENT KEY SYSTEM]
DIAGNOSIS AND REPAIR WORKFLOW
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?
Ye s > > G O T O 8 .
No >> Check voltage of related BCM terminals using CONSULT-III.
8.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 9.
9.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 7.
YES (Symptom remains)>>GO TO 6.
NO >> Inspection end
