Operate the turn switch to the RH position. Retrieve the front body control module (FBCM) DTCs using the M-MDS. (See DTC INSPECTION [FRONT BODY CONTROL MODULE (FBCM)] .) Is the same DTC displayed?	Yes	Replace the front combination light (RH), then go to Step 17. (See FRONT COMBINATION LIGHT REMOVAL/INSTALLATION .)
8		No	Go to Step 18.
9	INSPECT REAR TURN LIGHT BULB (RH) Inspect the rear turn light bulb (RH). Is the rear turn light bulb (RH) normal?	Yes	Go to the next step.
9		No	Replace the rear turn light bulb (RH), then go to Step 17. (See REAR TURN LIGHT BULB REMOVAL/INSTALLATION .)
10	INSPECT REAR COMBINATION LIGHT (RH) CONNECTOR CONDITION Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the rear combination light (RH) connector. 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.
10		No	Repair or replace the connector, then go to Step 17.
11	INSPECT FRONT BODY CONTROL MODULE (FBCM) CONNECTOR CONDITION Disconnect the front body control module (FBCM) connector. 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.
11		No	Repair or replace the connector, then go to Step 17.
12	INSPECT REAR TURN LIGHT (RH) CONTROL CIRCUIT FOR SHORT TO GROUND Verify that the rear combination light (RH) and front body control module (FBCM) connectors are disconnected. Inspect for continuity between front body control module (FBCM) terminal 1E (wiring harness-side) and body ground. Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between rear combination light (RH) terminal A and front body control module (FBCM) terminal 1E. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.

Inspect for continuity between front body control module (FBCM) terminal 1F (wiring harness-side) and body ground. Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between power outer mirror (RH) terminal E and front body control module (FBCM) terminal 1F. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to ground. Go to the next step.
