Intrusion Sensor Fails To Trip VTSS (Export Only)

NOTE: After making any repairs, perform VTSS VERIFICATION TEST  under VERIFICATION TESTS.
  1. Ensure the IOD fuse is installed. Using the DRBIII, read the module configuration and ensure it is configured for PREMIUM VTA. With the DRBIII select: THEFT ALARM, VTSS, SYSTEM TEST and INTRUSION SENSOR TEST. While waving your hand around the intrusion sensor, read the DRBIII. If the DRBIII displays INTRUSION DETECTED, verify the system has not been armed with the intrusion sensor disabled. Replace the intrusion sensor if the problem remains intermittent. If the DRBIII does not display INTRUSION DETECTED, go to the next step.
  2. Disconnect the intrusion sensor connector. See Figure. Measure the voltage between the fused B+ circuit and ground. If the voltage is above 10 volts, go to the next step. If the voltage is below 10 volts, repair the fused B+ circuit for an open between the IOD fuse and the intrusion sensor.
  3. Disconnect the intrusion sensor connector. Turn the ignition and all the lights off. Measure the resistance between ground and the ground circuit. If the resistance is below 5 ohms, go to the next step. If the resistance is above 5 ohms, repair the ground circuit for an open.
  4. Disconnect the intrusion sensor connector. Disconnect the remote keyless entry module connector. See Figure. Measure the resistance of the intrusion sensor signal circuit between the sensor connector and the RKE module connector. If the resistance is below 5 ohms, go to the next step. If the resistance is above 5 ohms, repair the intrusion sensor signal circuit for an open.
  5. Turn the ignition and all the lights off. Disconnect the intrusion sensor connector. Disconnect the remote keyless entry module connector. Measure the resistance of the intrusion sensor signal circuit to ground. If the resistance is below 1000 ohms, repair the intrusion sensor signal circuit for a short to ground. If the resistance is above 1000 ohms, go to the next step.
  6. Disconnect the intrusion sensor connector. Backprobe a voltmeter lead to the intrusion sensor signal circuit in the sensor connector and the other lead to ground. Reconnect the intrusion sensor connector. Wave your hand around the intrusion sensor and observe the voltmeter. If the voltage is between 3 and 6 volts, replace the remote keyless entry module, then see BODY VERIFICATION TEST  under VERIFICATION TESTS. If the voltage is not between 3 and 6 volts, replace the intrusion sensor.
