Yes
Go to the next step.
No
Replace the front turn light bulb (LH), then go to Step 10.
4
INSPECT REAR TURN LIGHT (LH) CONNECTOR CONDITION
•  Disconnect the rear turn 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.
No
Repair or replace the connector, then go to Step 10.
5
INSPECT REAR TURN LIGHT BULB (LH)
•  Inspect the rear turn light bulb (LH).
•  Is the rear turn light bulb (LH) normal?
Yes
Go to the next step.
No
Replace the rear turn light bulb (LH), then go to Step 10.
6
INSPECT POWER OUTER MIRROR (LH) CONNECTOR CONDITION
•  Disconnect the power outer mirror (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.
No
Repair or replace the connector, then go to Step 10.
7
INSPECT SIDE TURN LIGHT (LH)
•  Inspect the side turn light (LH).
•  Is the side turn light (LH) normal?
Yes
Go to the next step.
No
Replace the side turn light (LH), then go to Step 10.
8
INSPECT FRONT BODY CONTROL MODULE (FBCM) CONNECTOR CONDITION
•  Disconnect the front body control module (FBCM) 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 10.
9
INSPECT TURN LIGHT (LH) CONTROL CIRCUIT FOR SHORT TO GROUND
•  Verify that the front combination light (LH), rear turn light (LH), power outer mirror (LH) and front body control module (FBCM) connectors are disconnected.
•  Inspect for continuity between the following terminals (vehicle wiring harness side) and body ground.
―  Front body control module (FBCM) terminal 2B
―  Front body control module (FBCM) terminal 2F
―  Front body control module (FBCM) terminal 2D
•  Is there continuity?
Yes
Repair or replace the wiring harness, then go to the next step.
No
Go to the next step.
10
VERIFY THAT REPAIRS HAVE BEEN COMPLETED
•  Reconnect all the disconnected connectors.
•  Clear front body control module (FBCM) DTCs using the M-MDS.
•  Switch the ignition ON (engine off or on).
•  Operate the turn switch in LH position.
•  Perform the front body control module (FBCM) DTC inspection using the M-MDS.
•  Is DTC B1D06:11 displayed?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the front body control module (FBCM), then go to the next step.
No
Go to the next step.
11
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair the malfunctioning part according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
