|
VERIFY FRONT TURN LIGHT (LH) CONNECTOR CONDITION
• Disconnect the front turn light (LH) connector.
• Inspect the connection condition and wiring harness.
• Are the connector terminals normal without damage, deformation, corrosion, or disconnection?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector, then go to the final step.
|
||
4
|
INSPECT WIRING HARNESS BETWEEN FRONT TURN LIGHT (LH) AND BODY GROUND FOR OPEN CIRCUIT
• Front turn light (LH) connector is disconnected.
• Inspect for continuity between front turn light (LH) terminal G (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the related wiring harness, then go to the final step.
|
||
5
|
VERIFY FRONT SIDE TURN LIGHT (LH) CONNECTOR CONDITION
• Disconnect the front side turn light (LH) connector.

|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector, then go to the final step.
|
||
6
|
VERIFY WIRING HARNESS BETWEEN FRONT SIDE TURN LIGHT (LH) AND BODY GROUND FOR OPEN CIRCUIT
• Front turn light (LH) and front side turn light (LH) connectors are disconnected.
• Inspect for continuity between front side turn light (LH) terminal B (wiring harness-side) and body ground.
• Is there continuity?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the related wiring harness, then go to the final step.
|
||
7
|
VERIFY REAR TURN LIGHT (LH) CONNECTOR CONDITION
• Disconnect the rear turn light (LH) connector.
• Inspect the connection condition and wiring harness.
• Are the connector terminals normal without damage, deformation, corrosion, or disconnection?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector, then go to the final step.
|
||
8
|
INSPECT WIRING HARNESS BETWEEN REAR TURN LIGHT (LH) AND BODY GROUND FOR OPEN CIRCUIT
• Front turn light (LH), front side turn light (LH), and rear turn light (LH) connectors are disconnected.
• Inspect for continuity between the following terminals (wiring harness-side) and body ground:
• Is there continuity?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the related wiring harness, then go to the final step.
|
||
9
|
VERIFY BCM CONNECTOR CONDITION
• Disconnect the BCM connector.
• Inspect the connection condition and wiring harness.
• Are the connector terminals normal without damage, deformation, corrosion, or disconnection?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the connector, then go to the final step.
|
||
10
|
INSPECT WIRING HARNESS BETWEEN FRONT TURN LIGHT (LH), FRONT SIDE TURN LIGHT (LH), REAR TURN LIGHT (LH) AND BCM FOR SHORT TO POWER SUPPLY
• Front turn light (LH), front side turn light (LH), rear turn light (LH), and BCM connectors are disconnected.
• Reconnect the negative battery cable.
• Measure the voltage at the following terminals (wiring harness-side):
• Is there any voltage?
|
Yes
|
Repair or replace the related wiring harness, then go to the final step.
|
No
|
Go to the next step.
|
||
11
|
