Step	Inspection	Results	Action
1	INSPECT SWIVEL ACTUATOR (RH) FOR MALFUNCTION • Clear the DTC recorded in the memory. (See CLEARING DTC.) • Perform the DTC inspection for the adaptive front lighting system (AFS) control module. (See DTC INSPECTION.) • Is the same Pending DTC present?	Yes	Replace the front combination light (RH) and perform the repair completion verification. (See FRONT COMBINATION LIGHT REMOVAL/INSTALLATION.)
No	Go to repair completion verification 2.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED • Install/connect the part removed/disconnected during the troubleshooting procedure. • Clear the DTC recorded in the memory. (See CLEARING DTC.) • Perform the DTC inspection for the adaptive front lighting system (AFS) control module. (See DTC INSPECTION.) • Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].) If the CAN communication is normal, perform the diagnosis from Step 1. • If the malfunction recurs, replace the adaptive front lighting system (AFS) control module, then go to the next step. (See ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE REMOVAL/INSTALLATION.)
No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTC IS DISPLAYED • Perform the DTC inspection. (See DTC INSPECTION.) • Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
No	DTC troubleshooting completed.
