Diagnostic Procedure

DTC U3003:16 (ADAPTIVE FRONT LIGHTING SYSTEM CONTROL MODULE) DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	VERIFY PCM DTCs Perform the DTC inspection for the PCM using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5)] .) Is the DTC displayed?	Yes	Repair the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-G 2.5)] .)
1		No	Go to the next step.
2	INSPECT BATTERY Inspect the battery. (See BATTERY INSPECTION [SKYACTIV-G 2.5] .) Is the battery normal?	Yes	Go to the next step.
2		No	Recharge or replace the battery, then go to Step 6. (See BATTERY RECHARGING [SKYACTIV-G 2.5] .) (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.5] .)
3	INSPECT GENERATOR Inspect the generator. (See GENERATOR INSPECTION [SKYACTIV-G 2.5 (WITHOUT i-ELOOP)] .) (See GENERATOR INSPECTION [i-ELOOP] .) Is the generator normal?	Yes	Go to the next step.
3		No	Replace the generator, then go to Step 6. (See GENERATOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5 (WITHOUT i-ELOOP)] .) (See GENERATOR REMOVAL/INSTALLATION [i-ELOOP] .)
4	INSPECT AFS CONTROL MODULE CONNECTOR CONDITION Switch the ignition to off. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5] .) Disconnect the AFS control module connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
4		No	Repair or replace the connector, then go to Step 6.
5	VERIFY AFS CONTROL MODULE POWER SUPPLY VOLTAGE Reconnect all the disconnected connectors. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5] .) Display PID VPWR_IG using the M-MDS. (See PID/DATA MONITOR INSPECTION [ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE] .) Is the voltage B+?	Yes	Go to the next step.
5		No	Inspect the METER1 10 A fuse. If a fuse is burnt out: Repair or replace the wiring harness which is shorted to ground. Replace the fuse. If a fuse is damaged: Replace the fuse. If the fuse is normal: Repair or replace the wiring harness which has an open circuit. Go to the next step.
6	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Reconnect all the disconnected connectors. Reconnect the disconnected negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5] .) 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 DTC U3003:16 displayed?	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 .)
6		No	Go to the next step.
7	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] .)
7		No	DTC troubleshooting completed.
