Diagnostic Procedure

Step	Inspection		Action
1	VERIFY AUTO LEVELING CONTROL MODULE OR ADAPTIVE LED HEADLIGHTS CONTROL MODULE DTCs • Retrieve the adaptive LED headlights system DTCs using the M-MDS. (See DTC INSPECTION [HEADLIGHT AUTO LEVELING SYSTEM].) (See DTC INSPECTION [ADAPTIVE LED HEADLIGHTS CONTROL MODULE].) • Are any DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [HEADLIGHT AUTO LEVELING SYSTEM].) (See DTC TABLE [ADAPTIVE LED HEADLIGHTS CONTROL MODULE].)
1		No	Go to the next step.
2	VERIFY IF MALFUNCTIONING LOCATION IS AUTO LEVELING CONTROL MODULE OR ADAPTIVE LED HEADLIGHTS CONTROL MODULE DEPENDING ON REPEATABILITY • Clear the DTC for the forward sensing camera (FSC) using the M-MDS. (See CLEARING DTC [FORWARD SENSING CAMERA (FSC)].) • Switch the ignition ON (engine off or on) and wait for 6.5 s or more. • Retrieve the forward sensing camera (FSC) DTCs using the M-MDS. (See DTC INSPECTION [FORWARD SENSING CAMERA (FSC)].) • Is the same DTC displayed?	Yes	Replace the auto leveling control module or adaptive LED headlights control module, then go to the next step. (See AUTO LEVELING CONTROL MODULE REMOVAL/INSTALLATION.) (See ADAPTIVE LED HEADLIGHTS CONTROL MODULE REMOVAL/INSTALLATION.)
2		No	Go to Step 4.
3	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the forward sensing camera (FSC) using the M-MDS. (See CLEARING DTC [FORWARD SENSING CAMERA (FSC)].) • Switch the ignition ON (engine off or on) and wait for 6.5 s or more. • Retrieve the forward sensing camera (FSC) DTCs using the M-MDS. (See DTC INSPECTION [FORWARD SENSING CAMERA (FSC)].) • Is the same DTC displayed?	Yes	Replace the forward sensing camera (FSC), then go to the next step. (See FORWARD SENSING CAMERA (FSC) REMOVAL/INSTALLATION.)
3		No	Go to the next step.
4	VERIFY IF OTHER DTCs DISPLAYED • Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [FORWARD SENSING CAMERA (FSC)].)
4		No	DTC troubleshooting completed.
