Diagnostic Procedure

Step	Inspection		Action
1	INSPECT FRONT COMBINATION LIGHT (LH) CONNECTOR CONDITION • Switch the ignition to off. • Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) • Disconnect the front combination light (LH) 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.
1		No	Repair or replace the connector, then go to Step 7.
2	INSPECT FRONT COMBINATION LIGHT (RH) CONNECTOR CONDITION • Disconnect the front combination light (RH) 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.
2		No	Repair or replace the connector, then go to Step 7.
3	INSPECT AFS CONTROL MODULE CONNECTOR CONDITION • 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.
3		No	Repair or replace the connector, then go to Step 7.
4	INSPECT HEADLIGHT LEVELING ACTUATOR CIRCUIT FOR SHORT TO GROUND • Verify that the following connectors are disconnected. ― Front combination light (LH) ― Front combination light (RH) ― AFS control module • Inspect for continuity between the following terminals (vehicle wiring harness side) and body ground. ― Front combination light (LH) terminal I ― Front combination light (LH) terminal F ― Front combination light (RH) terminal I ― Front combination light (RH) terminal F • Is there continuity?	Yes	Repair or replace the wiring harness which is shorted to ground, then go to Step 7.
4		No	Go to the next step.
5	INSPECT HEADLIGHT LEVELING ACTUATOR CIRCUIT FOR OPEN CIRCUIT • Verify that the following connectors are disconnected. ― Front combination light (LH) ― Front combination light (RH) ― AFS control module • Inspect the wiring harness between the following terminals (vehicle wiring harness side) for continuity. ― AFS control module terminal B and front combination light (LH) terminal I ― AFS control module terminal P and front combination light (LH) terminal F ― AFS control module terminal B and front combination light (RH) terminal I ― AFS control module terminal P and front combination light (RH) terminal F • Is there continuity?	Yes	Go to the next step.
5		No	Repair or replace the wiring harness which has an open circuit, then go to Step 7.
6	INSPECT HEADLIGHT LEVELING ACTUATOR OPERATION • Perform the headlight leveling actuator operation check mode. (See HEADLIGHT LEVELING ACTUATOR OPERATION CHECK MODE [ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE].) • Does the headlight leveling actuator operate normally?	Yes	Go to the next step.
6		No	Replace the front combination light, then go to the next step. (See FRONT COMBINATION LIGHT REMOVAL/INSTALLATION.)
7	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 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].) • 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 B1041:14 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.)
7		No	Go to the next step.
8	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].)
8		No	DTC troubleshooting completed.
