Diagnostic Procedure

Step	Inspection		Action
1	PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS SWIVEL ACTUATOR (LH) • Clear the AFS control module DTCs using the M-MDS. (See CLEARING DTC [ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE].) • Switch the ignition ON (engine off or on) and wait for 5 s or more. • Perform the DTC inspection for the AFS control module using the M-MDS. (See DTC INSPECTION [ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE].) • Is the same Pending DTC present?	Yes	Replace the front combination light (LH), then go to the next step. (See FRONT COMBINATION LIGHT REMOVAL/INSTALLATION.)
1		No	Go to Step 3.
2	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the AFS control module DTCs using the M-MDS. (See CLEARING DTC [ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE].) • Switch the ignition ON (engine off or on) and wait for 5 s or more. • Perform the DTC inspection for the AFS control module using the M-MDS. (See DTC INSPECTION [ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE].) • Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the AFS control module, then go to the next step. (See ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE REMOVAL/INSTALLATION.)
2		No	Go to the next step.
3	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE].)
3		No	DTC troubleshooting completed.
