For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
When the output is off.

- Set Condition:
When the output is off and voltage is not detected by the BCM for at least 125 milliseconds on the VTSS Lamp Output circuit, this code will set.





Diagnostic Test

1. PRE-TEST

NOTE: Ensure that VTSS operates correctly before performing this proceedure.

Turn the ignition on.
With the scan tool, record and erase DTCs.
Cycle the ignition Off, then On.
With the scan tool, read DTCs.
Did this DTC reset?

Yes

- Go To2

No

- The condition is not present at this time. Visually inspect the related wiring harness and connector terminals. Search for any Technical Service Bulletins (TSB) that may apply.
- Perform VTSS VERIFICATION TEST - VER 1. Vehicle Theft Security Verification Tests

2. CIRCUIT CHECKS




Turn the ignition off.
Disconnect the VTSS Indicator harness connector.
Using a 12-volt test light connected to ground, probe the VTSS Indicator Driver circuit.
Turn the ignition on.
With the scan tool, actuate the VTSS Lamp.
Does the test light illuminate brightly?

Yes

- Go To3

No

- Go To4

3. VTSS INDICATOR GROUND CIRCUIT OPEN




Turn the ignition off.
Disconnect the VTSS Indicator harness connector.
Measure the resistance between ground and the VTSS Indicator Ground circuit.
Is the resistance above 3.0 ohms?

Yes

- Repair the VTSS Indicator Ground circuit for an open.
- Perform VTSS VERIFICATION TEST - VER 1. Vehicle Theft Security Verification Tests

No

- Replace the VTSS Indicator.
- Perform VTSS VERIFICATION TEST - VER 1. Vehicle Theft Security Verification Tests

4. VTSS INDICATOR DRIVER CIRCUIT OPEN




Turn the ignition off.
Disconnect the VTSS Indicator harness connector.
Disconnect the BCM C2 harness connector.
Measure the resistance of the VTSS Indicator Driver circuit between the VTSS Indicator connector and the BCM C2 connector.
Is the resistance above 3.0 ohms?

Yes

- Repair the VTSS Indicator Driver circuit for an open.
- Perform VTSS VERIFICATION TEST - VER 1. Vehicle Theft Security Verification Tests

No

- Replace the Body Control Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
