TEST ACTION APPLICABILITY
1 Ensure the IOD fuse is installed.
Using the DRBIIIt, read the module configuration and ensure it is configured for
PREMIUM VTA.
With the DRBIIIt select: THEFT ALARM, VTSS, SYSTEM TEST and INTRUSION
SENSOR TEST.
While waving your hand around the Intrusion Sensor, read the DRBIIIt.
Does the DRBIIIt display INTRUSION DETECTED?
All
Yes → Verify the system has not been armed with the intrusion sensor
disabled. Replace the Intrusion Sensor if the problem remains
intermittent.
Perform VTSS VERIFICATION TEST - 1A.
No → Go To 2
2 Disconnect the Dome Lamp/Intrusion Sensor connector.
Measure the voltage between the Fused B(+) circuit and ground.
Is the voltage above 10.0 volts?
All
Yes → Go To 3
No → Repair the Fused B(+) circuit for an open between the IOD fuse
and the Intrusion Sensor.
Perform VTSS VERIFICATION TEST - 1A.
3 Disconnect the Dome Lamp/Intrusion Sensor connector.
Turn the ignition and all the lights off.
Measure the resistance between ground and the Ground circuit.
Is the resistance below 5.0 ohms?
All
Yes → Go To 4
No → Repair the Ground circuit for an open.
Perform VTSS VERIFICATION TEST - 1A.
