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 B1D07:11 displayed?

Yes

Go to the next step.

No

DTC troubleshooting completed.

2

VERIFY FRONT TURN LIGHT (RH) CONNECTOR CONDITION

•  Turn the ignition switch to the LOCK position.

•  Disconnect the negative battery cable.

•  Disconnect the front turn light (RH) 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 FRONT SIDE TURN LIGHT (RH) CONNECTOR CONDITION

•  Disconnect the front side turn light (RH) 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.

4

VERIFY REAR TURN LIGHT (RH) CONNECTOR CONDITION

•  Disconnect the rear turn light (RH) 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 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.

6

VERIFY FOR SHORT TO GROUND IN WIRING HARNESS BETWEEN FRONT TURN LIGHT (RH), FRONT SIDE TURN LIGHT (RH), REAR TURN LIGHT (RH) AND BCM

•  Front turn light (RH), front side turn light (RH), rear turn light (RH) and BCM connectors are disconnected.

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

―  BCM terminal 1K

―  BCM terminal 3J

•  Is there continuity?

Yes

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

No

Go to the next step.

7

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 B1D07:11 displayed?

Yes

Replace the BCM.

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

No

DTC troubleshooting completed.
