Diagnostic Procedure

Step	Inspection	Results	Action
1	VERIFY BODY CONTROL MODULE (BCM) DTCs •  Perform the DTC inspection for the body control module (BCM). (See DTC INSPECTION.) •  Is a DTC displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [BODY CONTROL MODULE (BCM) (E)].)
		No	Go to the next step.
2	RESET CONFIGURATION DATA FOR BODY CONTROL MODULE (BCM) •  Using the M-MDS, perform the body control module (BCM) configuration. (See CONFIGURATION.) •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Switch the ignition ON (engine off or on) and wait for 30 s or more. •  Perform the DTC inspection for the adaptive LED headlights control module. (See DTC INSPECTION.) •  Is the same Pending DTC present?	Yes	Perform the body control module (BCM) configuration again and perform the repair completion verification. (See CONFIGURATION.)
		No	Go to repair completion verification 2.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Switch the ignition ON (engine off or on) and wait for 30 s or more. •  Perform the DTC inspection for the adaptive LED headlights 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 LED headlights control module, then go to the next step. (See ADAPTIVE LED HEADLIGHTS 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.
