Diagnostic Procedure

Step

Inspection

Action
1
VERIFY FRONT BODY CONTROL MODULE (FBCM) DTCs
•  Retrieve the front body control module (FBCM) DTCs using the M-MDS.
•  Are any other DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [FRONT BODY CONTROL MODULE (FBCM)].)
No
Go to the next step.
2
INSPECT FRONT COMBINATION LIGHT (RH) CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the negative battery cable.
•  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.
No
Repair or replace the connector, then go to Step 5.
3
INSPECT ADAPTIVE LED HEADLIGHTS CONTROL MODULE CONNECTOR CONDITION
•  Disconnect the adaptive LED headlights 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.
No
Repair or replace the connector, then go to Step 5.
4
VERIFY IF MALFUNCTIONING LOCATION IS FRONT COMBINATION LIGHT (RH) DEPENDING ON REPEATABILITY
•  Always reconnect all disconnected connectors.
•  Connect the negative battery cable.
•  Clear the DTC for the adaptive LED headlights control module using the M-MDS.
•  Operate the light switch to the HEAD position and the dimmer switch to the LO position.
•  Switch the ignition ON (engine off or on) and wait for 5 s or more.
•  Retrieve the adaptive LED headlights control module DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Replace the front combination light (RH), then go to the next step.
(See FRONT COMBINATION LIGHT REMOVAL/INSTALLATION.)
No
Go to Step 6.
5
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Always reconnect all disconnected connectors.
•  Connect the negative battery cable.
•  Clear the DTC for the adaptive LED headlights control module using the M-MDS.
•  Operate the light switch to the HEAD position and the dimmer switch to the LO position.
•  Switch the ignition ON (engine off or on) and wait for 5 s or more.
•  Retrieve the adaptive LED headlights control module DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the adaptive LED headlights control module.
Go to the next step.
No
Go to the next step.
6
VERIFY IF OTHER DTCs DISPLAYED
