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-III.
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 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 8
YES (Symptom remains)>>GO TO 6
NO >>INSPECTION END

REAR WINDOW DEFOGGER SYSTEM
System DiagramINFOID:0000000001697541
System DescriptionINFOID:0000000001697542
Operation Description
Turn rear window defogger switch ON when the ignition switch is turned ON. Then controller (auto amp.)
(rear window defogger switch) transmits rear window defogger switch signal to BCM.
BCM turns rear window defogger relay ON when rear window defogger switch signal is received.
Rear window defogger and door mirror defogger (with door mirror defogger) are supplied with power and
operate when rear window defogger relay turns ON.
BCM transmits rear window defogger control signal to IPDM E/R via CAN communication when rear window
defogger operates.
Rear window defogger ON is displayed when controller (auto amp.) receives signals.
Timer function
BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch
is turned ON while ignition switch is ON. It makes rear window defogger and door mirror defogger (with door
mirror defogger) operate.
Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns
rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF.
