DIAGNOSIS AND REPAIR WORKFLOW
Work Flow
OVERALL SEQUENCE

DETAILED FLOW
1.GET INFORMATION FOR SYMPTOM
>> GO TO 2.
2.CHECK DTC
Are any symptoms described and any DTC detected? Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>GO TO 5.
3.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
Also study the normal operation and fail-safe related to the symptom.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5.
4.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
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 detected DTC, and then check that DTC is detected again. At this time, always connect CONSULT to the vehicle, and check self diagnostic results in real time.
If two or more DTCs are detected, refer to BCS-47, "DTC Inspection Priority Chart" (BCM) (with Intelligent Key System) or BCS-107, "DTC Inspection Priority Chart" (BCM) (without Intelligent Key System) or PCS- 12, "Reference Value" (IPDM E/R), and determine trouble diagnosis order.
NOTE:
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 >> Check according to GI-41, "Intermittent Incident".
6.DETECT MALFUNCTIONING SYSTEM BY SYMPTOM DIAGNOSIS
Detect malfunctioning system according to SYMPTOM DIAGNOSIS based on the confirmed symptom in step 4, and determine the trouble diagnosis order based on possible causes and symptom.
Is the symptom described? YES >> GO TO 7.
NO >> Monitor input data from related sensors or check voltage of related module terminals using CONSULT.
7.DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
Is malfunctioning part detected? YES >> GO TO 8.
NO >> Check according to GI-41, "Intermittent Incident".
8.REPAIR OR REPLACE THE MALFUNCTIONING PART
>> GO TO 9.
9.FINAL CHECK
When DTC is detected in step 2, perform DTC CONFIRMATION PROCEDURE again, and then check that the malfunction is repaired securely.
When symptom is described by the customer, refer to confirmed symptom in step 3 or 4, and check that the symptom is not detected.
Is DTC detected and does symptom remain? YES-1 >> DTC is detected: GO TO 7.
YES-2 >> Symptom remains: GO TO 4.
NO >> Before returning the vehicle to the customer, always erase DTC.

CAUTION:
ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Special Repair Requirement
1.SENSOR INITIALIZE
CONSULT WORK SUPPORT
Perform “SENSOR INITIALIZE”. Refer to EXL-85, "SENSOR INITIALIZE : Special Repair Requirement".
>> WORK END
SENSOR INITIALIZE
SENSOR INITIALIZE : Description
HEADLAMP AIMING CONTROL SYSTEM
Perform the sensor initialize when installing, removing and replacing the auto levelizer control unit or suspension components.
SENSOR INITIALIZE : Special Repair Requirement
CAUTION: If performing aiming adjustment after the levelizer initialization, be sure to start the engine after turning ignition switch OFF.
1.VEHICLE CONDITION CHECK
>> GO TO 2.
2.SENSOR INITIALIZE
CONSULT WORK SUPPORT
CAUTION: If “INITIALIZE NOT DONE” is indicated, auto levelizer control unit detects that the sensor lever signal was changing. The sensor initialization is cancelled. In this case, turn the ignition switch OFF, do not allow the vehicle height to change. Perform the sensor initialization again.
Is the sensor initialize completed? YES >> GO TO 3.
NO >> Perform the sensor initialize again.
3.SELF-DIAGNOSIS RESULT CHECK
Perform the self-diagnosis with CONSULT. Check that any DTC is not detected.
Is any DTC detected? YES >> GO TO 2.
NO >> Sensor initialize completed.
