APPLICABILITY
2
Turn the ignition off.
NOTE: The Intrusion Sensors will only detect movement during initial
ignition on.
With the DRBIII
t, select Intrusion Sensor Test.
Turn the ignition on then wave arm inside the vehicle to simulate an intrusion.
Does the DRBIII
t show INTRUSION DETECTED when the ignition is initially
turned on?
All
Yes
→ The condition that caused this symptom is currently not present.
Inspect the related wiring harness for a possible intermittent
condition.
Perform VTSS VERIFICATION TEST - 1A.
No
→ Go To 3
3
Turn the ignition off.
Disconnect the Front Intrusion Sensor connector.
Connect a voltmeter to the Front Intrusion Sensor Signal circuit at the Intrusion
Sensor connector.
Turn the ignition on while observing the voltmeter.
NOTE: Voltage will only be present during the first 6 seconds when the
ignition is turned on.
Is the voltage above 10.0 volts when the ignition is initially turned on?
All
Yes
→ Go To 4
No
→ Go To 12
4
Turn the ignition off.
Measure the resistance of the Sensor Ground circuit at the Front Intrusion Sensor
connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 5
No
→ Go To 11
5
Replace the Front Intrusion Sensor with a known good sensor.
With the DRBIII
t, select Intrusion Sensor Test.
Turn the ignition on then wave arm inside the vehicle to simulate an intrusion.
Does the DRBIII
t show INTRUSION DETECTED?
All
Yes
→ Replace the Front Intrusion Sensor.
Perform VTSS VERIFICATION TEST - 1A.
No
→ Go To 6
6
Turn the ignition off.
Disconnect the Rear Intrusion Sensor connector.
Connect a voltmeter to the Rear Intrusion Sensor Signal circuit at the Intrusion
Sensor connector.
Turn the ignition on while observing the voltmeter.
NOTE: Voltage will only be present during the first 6 seconds when the
ignition is turned on.
Is the voltage above 10.0 volts when the ignition is initially turned on?
All
Yes
→ Go To 7
No
→ Go To 10
