Diagnostic Procedure

Step

Inspection

Action

1

PERFORM DTC INSPECTION

•  Clear the DTCs using the M-MDS.
(See CLEARING DTC [BCM].)

•  Turn the turn switch off.

•  Perform the BCM DTC inspection using the M-MDS.
(See DTC INSPECTION [BCM].)

•  Is the DTC B1D36:92 displayed?

Yes

Go to the next step.

No

DTC troubleshooting completed.

2

VERIFY LIGHT SWITCH CONNECTOR CONDITION

•  Turn the ignition switch to the LOCK position.

•  Disconnect the negative battery cable.

•  Disconnect the light switch connector.

•  Inspect the connection condition and wiring harness.

•  Are the connector terminals normal without damage, deformation, corrosion, or disconnection?

Yes

Go to the next step.

No

Repair or replace the connector, then go to the final step.

3

VERIFY TURN SWITCH CONDITION

•  Inspect the turn switch.
(See LIGHT SWITCH INSPECTION.)

•  Is the turn switch normal?

Yes

Go to the next step.

No

Replace the light switch, then go to the final step.

(See LIGHT SWITCH REMOVAL/INSTALLATION.)

4

VERIFY BCM CONNECTOR CONDITION

•  Disconnect the BCM connector.

•  Inspect the connection condition and wiring harness.

•  Are the connector terminals normal without damage, deformation, corrosion, or disconnection?

Yes

Go to the next step.

No

Repair or replace the connector, then go to the final step.

5

VERIFY WIRING HARNESS BETWEEN LIGHT SWITCH AND BCM FOR SHORT TO GROUND

•  Light switch and BCM connectors are disconnected.

•  Inspect for continuity between the following terminals (wiring harness-side) and body ground:

―  BCM terminal 6A

―  BCM terminal 6B

•  Is there continuity?

Yes

Repair or replace the related wiring harness, then go to the final step.

No

Go to the next step.

6

VERIFY TROUBLESHOOTING COMPLETED

•  Reconnect all disconnected connectors.

•  Reconnect the negative battery cable.

•  Clear the DTCs using the M-MDS.
(See CLEARING DTC [BCM].)

•  Turn the turn switch off.

•  Perform the BCM DTC inspection using the M-MDS.
(See DTC INSPECTION [BCM].)

•  Is the DTC B1D36:92 displayed?

Yes

Replace the BCM.

(See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)

No

DTC troubleshooting completed.
