•  Short to GND in wiring harness between PJB terminal J-01 AK and front turn light (LH) terminal A or front side turn light (LH) terminal A
•  Open circuit in wiring harness between PJB terminal J-05 A and rear turn light (LH) terminal A
•  Short to power supply in wiring harness between PJB terminal J-05 A and rear turn light (LH) terminal A
•  Short to GND in wiring harness between PJB terminal J-05 A and rear turn light (LH) terminal A
•  Turn lights malfunction
•  PJB malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
INSPECT TURN LIGHT CONNECTOR
•  Turn the ignition switch off.
•  Disconnect all the turn light (LH) connectors.
•  Inspect all the turn light (LH) 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 TURN LIGHT CONTROL CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between following terminals:
―  PJB terminal J-01 AK (wiring harness-side) — front turn light (LH) terminal A (wiring harness-side)
―  PJB terminal J-01 AK (wiring harness-side) — front side turn light (LH) terminal A (wiring harness-side)
―  PJB terminal J-05 A (wiring harness-side) — rear turn light (LH) terminal A (wiring harness-side)
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 7.
4
INSPECT TURN LIGHT CONTROL CIRCUIT FOR SHORT TO GND
•  Inspect for continuity between following terminals:
―  PJB terminal J-01 AK (wiring harness-side) — body GND
―  PJB terminal J-01 AK (wiring harness-side) — body GND
―  PJB terminal J-05 A (wiring harness-side) — 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 TURN LIGHT CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Turn the ignition switch to the ON position (Engine off).
•  Measure the voltage between following terminals:
―  PJB terminal J-01 AK (wiring harness-side) — body GND
―  PJB terminal J-01 AK (wiring harness-side) — body GND
―  PJB terminal J-05 A (wiring harness-side) — 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 TURN LIGHT
•  Inspect all the turn lights.
•  Is there any malfunction?
Yes
Replace the turn lights, 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.
