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.)
- 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 to the vehicle in “DATA MONITO R” 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 to the vehicle in “DATA MONITO R” 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 to the v ehicle, and check diagnostic results in real time.
If two or more DTCs are detected, refer to BCS-50, "DTC Inspection Priority Chart"
and determine trouble
diagnosis order.
NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC Confirma tion 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 8.
NO >> Refer to GI-43, "Intermittent Incident"
.
6. PERFORM BASIC INSPECTION
Perform DEF-16, "Work Flow"
.
>> GO TO 7
7. DETECT MALFUNCTIONING SY STEM BY SYMPTOM TABLE
Detect malfunctioning system according to DEF-7, "System Description"
based on the confirmed symptom in
step 4, and determine the trouble diagnosis or der based on possible causes and symptom.
>> GO TO 8.

DIAGNOSIS AND REPAIR WORKFLOW
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.
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 C onfirmation 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.

Regarding Wiring Diagram information, refer to DEF-11, "Wiring Diagram".
1.CHECK REAR WINDOW DEFOGGER RELAY OPERATION
1. Push the ignition switch to ON.
2. Check that an operation noise of rear window defogger relay [located in fuse block (J/B)] can be heard
when pressing the rear window defogger switch ON and OFF.
Is the inspection result normal?
YES >> GO TO 2.
NO >> GO TO 5.
2.CHECK FUSE
Check if Fuse 22 from the rear window defogger relay output is blown.
Is the fuse blown?
YES >> Replace the blown fuse after repairing the affected circuit.
NO >> GO TO 3.
3. CHECK FOR VOLTAGE FROM THE REAR WINDOW DEFOGGER RELAY
1. Connect a voltmeter between Fuse block (J/B) and ground.
2. While pressing the rear window defogger switch ON and OFF, check for voltage between Fuse block (J/B)
and ground.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Perform rear window defogger relay diagnosis. Refer to DEF-26, "Diagnosis Procedure"
