Schematic Reference: Theft Deterrent System Schematics Connector End View Reference: Theft Deterrent System Connector End Views Important: Before attempting to diagnose the intrusion sensor, ensure that the intrusion sensor ENABLED, via the intrusion sensor defeat switch. DEFINITION: After arming, the Content Theft Deterrent (CTD) System does not enter alarm mode when there is motion inside the vehicle. | ||||

Does the test lamp illuminate? | -- | Go to Step 3 | Go to Step 7 |
3 | With a DMM, measure the voltage of the intrusion sensor alarm on signal circuit at the intrusion sensor harness connector. Is the voltage near the specified value? | B+ | Go to Step 4 | Go to Step 5 |
4 | Test the intrusion sensor armed signal circuit for a short to ground, or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 11 | Go to Step 6 |
5 | Test the intrusion sensor alarm on signal circuit for an open or a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 11 | Go to Step 9 |
6 | Inspect for a loose or poor connection at the harness connector of the intrusion sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 11 | Go to Step 8 |
7 | Repair the intrusion sensor battery positive voltage circuit. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | -- | Go to Step 11 | -- |
8 | Replace the intrusion sensor. Refer to Theft Deterrent Sensor Replacement . Did you correct the condition? | -- | Go to Step 11 | Go to Step 9 |
9 | Inspect for a loose or poor connection at the harness connector of the body control module (BCM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 11 | Go to Step 10 |
10 | Replace the BCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement? | -- | Go to Step 11 | -- |
11 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 2 |
