1 | Did you perform the Theft Deterrent System Diagnostic System Check? | -- | Go to Step 2 | |
2 | Were you sent here from Content Theft Deterrent (CTD) Alarm Mode Inoperative? | -- | Go to Step 3 | |
3 |
Does the test lamp illuminate? | -- | Go to Step 4 | Go to Step 8 |
4 | With a digital multimeter (DMM), measure the voltage of the intrusion sensor signal circuit at the intrusion sensor harness connector. Is the voltage near the specified value? | 12 V | Go to Step 5 | Go to Step 6 |
5 | Test the intrusion sensor low reference circuit for a short to voltage, 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 12 | Go to Step 7 |
6 | Test the intrusion sensor 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 12 | Go to Step 10 |
7 | 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 12 | Go to Step 9 |
8 | Repair the intrusion sensor battery positive voltage circuit. Refer to Wiring Repairs in Wiring Systems. Did you correct the condition? | -- | Go to Step 12 | -- |
9 | Replace the intrusion sensor. Refer to Theft Deterrent Sensor Replacement . Did you correct the condition? | -- | Go to Step 12 | Go to Step 10 |
10 | Inspect for a loose or poor connection at the harness connector of the rear integration module (RIM). 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 12 | Go to Step 11 |
11 | Replace the RIM. Refer to Rear Integration Body Control Module Replacement in Body Control System. Did you complete the repair? | -- | Go to Step 12 | -- |
12 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 3 |
