•  Front combination light (LH) connector or terminals malfunction
•  AFS control module connector or terminals malfunction
•  Short to ground in wiring harness between the following terminals:
―  AFS control module terminal T—Front combination light (LH) terminal K
―  AFS control module terminal U—Front combination light (LH) terminal J
•  Open circuit in wiring harness between the following terminals:
―  AFS control module terminal T—Front combination light (LH) terminal K
―  AFS control module terminal U—Front combination light (LH) terminal J
•  Swivel actuator (LH) malfunction
•  AFS control module malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION
1
INSPECT FRONT COMBINATION LIGHT (LH) CONNECTOR AND TERMINALS
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Disconnect the front combination light (LH) connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 6.
No
Go to the next step.
2
INSPECT AFS CONTROL MODULE CONNECTOR AND TERMINALS
•  Disconnect the AFS control module connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 6.
No
Go to the next step.
3
INSPECT SWIVEL ACTUATOR (LH) CIRCUIT FOR SHORT TO GROUND
•  Front combination light (LH) and AFS control module connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  Front combination light (LH) terminal K
―  Front combination light (LH) terminal J
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to Step 6.
No
Go to the next step.
4
INSPECT SWIVEL ACTUATOR (LH) CIRCUIT FOR OPEN CIRCUIT
•  Front combination light (LH) and AFS control module connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  AFS control module terminal T—Front combination light (LH) terminal K
―  AFS control module terminal U—Front combination light (LH) terminal J
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 6.
5
VERIFY SWIVEL ACTUATOR (LH) MALFUNCTION
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from the AFS control module using the M-MDS.
•  Perform the DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Replace the front combination light (LH), then go to the next step.
(See FRONT COMBINATION LIGHT REMOVAL/INSTALLATION.)
No
Go to Step 7.
6
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from the AFS control module using the M-MDS.
•  Perform the DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Replace the AFS control module, then go to the next step.
(See AFS (ADAPTIVE FRONT LIGHTING SYSTEM) CONTROL MODULE REMOVAL/INSTALLATION.)
No
Go to the next step.
7
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [AFS (ADAPTIVE FRONT LIGHTING SYSTEM)].)
No
DTC troubleshooting completed.
