9093-FRONT INTERIOR SECURITY SENSOR LOST COMMUNICATION WITH REAR INTERIOR SECURITY SENSOR





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
When the VTSS is armed.

- Set Condition:
If the Roof Control Module detects a loss of communication with the Intrusion 3 Sensor.





Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTC's.
Turn the ignition off and remove the key from the ignition.
Close all doors and arm the VTSS and wait two minutes.
Disarm the VTSS turn the ignition on.
Turn the ignition on and with the scan tool, read DTC's.
Does the scan tool display 9093-FRONT INTERIOR SECURITY SENSOR LOST COMMUNICATION WITH REAR INTERIOR SECURITY SENSOR?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST - VER 1Verification Tests

2. CHECK INTRUSION SENSOR 1 DATA 3 CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect the Intrusion 3 Sensor 4 - way connector.
Disconnect the Roof Control Module 6 - way connector.
Measure the resistance between the Intrusion Sensor 1 Data 3 circuit at the Intrusion 3 Sensor 4 - way connector to chassis ground.
Is the resistance below 5.0 ohms?

Yes

- Repair the Intrusion Sensor 1 Data 3 circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1Verification Tests

No

- 3


3. CHECK INTRUSION SENSOR 1 DATA 3 CIRCUIT FOR AN OPEN
Turn the ignition off.
Measure the resistance of the Intrusion Sensor 1 Data 3 circuit between the Intrusion 3 Sensor 4 - way connector and the Roof Control Module 6 - way connector.
Is the resistance below 3.0 ohms?

Yes

- Replace the Intrusion 3 Sensor with a known good sensor and retry to set DTC. If DTC resets Replace the Roof Control Module.
- Perform BODY VERIFICATION TEST - VER 1Verification Tests

No

- Repair the Intrusion Sensor 1 Data 3 circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1Verification Tests
