No

Go to the next step.

8

INSPECT THEFT-DETERRENT CONTROL MODULE POWER SUPPLY CIRCUIT FOR SHORT TO GROUND

•  Verify that the theft-deterrent control module connector is disconnected.

•  Inspect for continuity between the theft-deterrent control module terminal W (wiring harness-side) and body ground.

•  Is there continuity?

Yes

Repair or replace the wiring harness for a possible short to ground, then go to Step 10.

No

Go to the next step.

9

INSPECT THEFT-DETERRENT CONTROL MODULE POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT

•  Verify that the theft-deterrent control module connector is disconnected.

•  Inspect for continuity between the theft-deterrent control module terminal W (wiring harness-side) and BCM terminal 5H (wiring harness-side).

•  Is there continuity?

Yes

Go to the next step.

No

Repair or replace the wiring harness for a possible short to ground, then go to the next step.

10

VERIFY TROUBLESHOOTING COMPLETED

•  Make sure to reconnect all disconnected connectors.

•  Reconnect the negative battery cable.

•  Clear the DTC using the M-MDS.
(See CLEARING DTC [THEFT-DETERRENT SYSTEM].)

•  Perform the theft-deterrent control module DTC inspection using the M-MDS.
