DIAGNOSIS AND REPAIR WORKFLOW
< BASIC INSPECTION > [INTELLIGENT KEY SYSTEM]
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 BCM and IPDM E/R.
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 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.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 6.
5.PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC Confirmation Procedure for the displayed 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 SEC-181, "DTC Inspection Priority Chart", and determine trouble
diagnosis order.
NOTE:
Perform Component Function Check if DTC Confirmation Procedure is not included in Service Manual. This
simplified check procedure is an effective alternative 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 Confirmation
Procedure.
Is DTC detected?
YES >> GO TO 7.
NO >> Refer to GI-38, "Intermittent Incident".
6.DETECT MALFUNCTIONING SYSTEM BY SYMPTOM TABLE
Detect malfunctioning system according to SEC-215, "Symptom Table" 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 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.
Revision: 2007 June SEC-6 G37 Coupe
DIAGNOSIS AND REPAIR WORKFLOW
< BASIC INSPECTION > [INTELLIGENT KEY SYSTEM]
Is malfunctioning part detected?
YES >> GO TO 8. A
NO >> Check voltage of related BCM terminals using CONSULT-III.
8.REPAIR OR REPLACE THE MALFUNCTIONING PART
B
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. C
>> GO TO 9.
D
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 has been repaired securely. E
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? F
YES (DTC is detected)>>GO TO 7.
YES (Symptom remains)>>GO TO 6.
NO >> INSPECTION END

ECM RE-COMMUNICATING FUNCTION
ECM RE-COMMUNICATING FUNCTION : Description INFOID:0000000001699903
Performing following procedure can automatically perform re-communication of ECM and BCM, but only when
the ECM has been replaced with a new one (*1).
*1: New one means a virgin ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT-III is not necessary)
