•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 11.
6
INSPECT TURN LIGHT (RH) CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY
•  Verify that the front combination light (RH), power outer mirror (RH), rear turn light (RH), and front body control module (FBCM) connectors are disconnected.
•  Switch the ignition ON (engine off or on).
•  Measure the voltage at the following terminals (vehicle wiring harness side).
―  Front body control module (FBCM) terminal 1G
―  Front body control module (FBCM) terminal 1F
―  Front body control module (FBCM) terminal 1E
•  Is the voltage 0 V?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 11.
7
INSPECT TURN LIGHT (RH) CONTROL CIRCUIT FOR OPEN CIRCUIT
•  Verify that the front combination light (RH), power outer mirror (RH), rear turn light (RH), and front body control module (FBCM) connectors are disconnected.
•  Switch the ignition to off.
•  Inspect the wiring harness between the following terminals (vehicle wiring harness side) for continuity.
―  Front combination light (RH) terminal D and front body control module (FBCM) terminal 1G (headlight bulb type)
―  Front combination light (RH) terminal E and front body control module (FBCM) terminal 1G (headlight LED type)
―  Power outer mirror (RH) terminal A and front body control module (FBCM) terminal 1F
―  Rear turn light (RH) terminal A and front body control module (FBCM) terminal 1E
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 11.
8
INSPECT SIDE TURN LIGHT (RH)
•  Inspect the side turn light (RH).
•  Is the side turn light (RH) normal?
Yes
