•  Rear window defroster relay malfunction
•  PJB malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
INSPECT REAR WINDOW DEFROSTER RELAY CONNECTOR
•  Turn the ignition switch off.
•  Disconnect the rear window defroster relay connector.
•  Inspect the rear window defroster relay connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 7.
No
Go to the next step.
2
INSPECT PJB CONNECTOR
•  Disconnect the PJB connector.
•  Inspect the PJB connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 7.
No
Go to the next step.
3
INSPECT REAR WINDOW DEFROSTER RELAY CONTROL CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between PJB terminal J-01 AH (wiring harness-side) and rear window defroster relay terminal E (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible short to GND, then go to Step 7.
4
INSPECT REAR WINDOW DEFROSTER RELAY CONTROL CIRCUIT FOR SHORT TO GND
•  Inspect for continuity between PJB terminal J-01 AH (wiring harness-side) and body GND.
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to GND, then go to Step 7.
No
Go to the next step.
5
INSPECT REAR WINDOW DEFROSTER RELAY CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Turn the ignition switch to the ON position (Engine off).
•  Measure the voltage between PJB terminal J-01 AH (wiring harness-side) and body GND.
•  Is the voltage B+?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 7.
No
Go to the next step.
6
INSPECT REAR WINDOW DEFROSTER RELAY
•  Inspect the rear window defroster relay.
•  Is there any malfunction?
Yes
Replace the rear window defroster relay, then go to the next step.
No
Go to the next step.
7
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PJB memory using the M-MDS.
•  Perform the self-test.
•  Is the same DTC present?
Yes
Replace the PJB.
