Diagnostic Procedure

Step	Inspection		Action
1	VERIFY INSTRUMENT CLUSTER DTCs • Retrieve the instrument cluster DTCs using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) • Are any DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [INSTRUMENT CLUSTER].)
1		No	Go to the next step.
2	RESET INSTRUMENT CLUSTER CONFIGURATION DATA • Using the M-MDS, perform the instrument cluster configuration (using As-Built data). (See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).) • Clear the DTC for the auto leveling control module using the M-MDS. (See CLEARING DTC [HEADLIGHT AUTO LEVELING SYSTEM].) • Switch the ignition ON (engine off or on) and wait for 30 s or more. • Retrieve the auto leveling control module DTCs using the M-MDS. (See DTC INSPECTION [HEADLIGHT AUTO LEVELING SYSTEM].) • Is the same DTC displayed?	Yes	Using the M-MDS, perform the instrument cluster configuration (using As-Built data) again, then go to the next step. (See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).)
2		No	Go to Step 4.
3	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Clear the DTC for the auto leveling control module using the M-MDS. (See CLEARING DTC [HEADLIGHT AUTO LEVELING SYSTEM].) • Switch the ignition ON (engine off or on) and wait for 30 s or more. • Retrieve the auto leveling control module DTCs using the M-MDS. (See DTC INSPECTION [HEADLIGHT AUTO LEVELING SYSTEM].) • Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the auto leveling control module. (See AUTO LEVELING CONTROL MODULE REMOVAL/INSTALLATION.) Go to the next step.
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 [HEADLIGHT AUTO LEVELING SYSTEM].)
4		No	DTC troubleshooting completed.
