| 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.
(See
PJB SELF-TEST ).
- Is the same DTC present?
|
Yes |
Replace the PJB.
(See
PASSENGER JUNCTION BOX (PJB) REMOVAL/INSTALLATION
.) |
| No |
DTC troubleshooting completed. |
