Diagnostic Procedure

Step

Inspection

Action

1

PERFORM DTC INSPECTION

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

•  Turn the hazard warning switch off.

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

•  Is DTC B1D35:11 displayed?

Yes

Go to the next step.

No

DTC troubleshooting completed.

2

VERIFY HAZARD WARNING SWITCH CONNECTOR CONDITION

•  Disconnect the negative battery cable.

•  Disconnect the hazard warning 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 HAZARD WARNING SWITCH CONDITION

•  Remove the hazard warning switch.
(See HAZARD WARNING SWITCH REMOVAL/INSTALLATION.)

•  Inspect hazard warning switch.
(See HAZARD WARNING SWITCH INSPECTION.)

•  Is the hazard warning switch normal?

Yes

Go to the next step.

No

Replace the hazard warning switch, then go to the final step.

(See HAZARD WARNING 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 HAZARD WARNING SWITCH AND BCM FOR SHORT TO GROUND

•  Inspect for a continuity between BCM terminal 6Q and body ground.

•  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

•  Connect all the connectors.

•  Connect the battery cable.

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

•  Turn the hazard warning switch off.

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

•  Is DTC B1D35:11 displayed?

Yes

Replace the BCM.

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

No

DTC troubleshooting completed.
