Diagnostic Procedure

Step

Inspection

Action

1
VERIFY BCM DTCs
•  Clear the DTCs using the M-MDS.
•  Turn the turn switch to the LEFT position, then RIGHT position.
•  Perform the BCM DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Go to the next step.
No
Go to Step 7.
2
INSPECT LIGHT SWITCH CONNECTOR AND TERMINALS
•  Turn the ignition switch to the LOCK position.
•  Disconnect the negative battery cable.
•  Disconnect the light switch 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 TURN SWITCH
•  Inspect the turn switch.
•  Is there any malfunction?
Yes
Replace the light switch, then go to Step 6.
No
Go to the next step.
4
INSPECT BCM CONNECTOR AND TERMINALS
•  Disconnect the BCM 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.
5
INSPECT TURN SWITCH CIRCUIT FOR SHORT TO GROUND
•  Verify that the light switch and BCM connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:
―  Light switch left side
•  Light switch terminal G
•  Light switch terminal E
―  Light switch right side
•  Light switch terminal G
•  Light switch terminal I
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to the next step.
No
Go to the next step.
6
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTCs using the M-MDS.
•  Turn the turn switch to the LEFT position, then RIGHT position.
•  Perform the BCM DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the BCM.
Go to the next step.
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.
No
DTC troubleshooting completed.
