VTSS Indicator Inoperative
Possible Causes:
- VTSS Indicator Lamp open.
- VTSS Indicator Driver circuit open.
- CTM.
CAUTION:
Always turn ignition off before disconnecting or connecting any control module connector. Failure to do so could result in damage to control module.
NOTE:
Ensure vehicle being tested has a fully charged battery. If it does not, false symptoms may occur.
NOTE:
For component location, see appropriate illustration under COMPONENT LOCATIONS

Testing:
- Turn ignition off. Connect DRBIII(R) to DLC. Disconnect Instrument Cluster C1 harness connector. Using 12-volt test light connected to 12 volts, probe Instrument Cluster C1 harness connector terminal No. 3. Turn ignition on. Using the DRBIII(R), select BCM, then actuate VTSS indicator. Does the test light illuminate when actuating VTSS indicator? If yes, replace Instrument Cluster. Perform VEHICLE THEFT SECURITY SYSTEM VERIFICATION TEST under VERIFICATION TESTS. If no, go to next step.
- Disconnect CTM C1 harness connector. Measure resistance between Instrument Cluster C1 harness connector terminal No. 3 and CTM C1 harness connector terminal No. 6. Is resistance less than 5 ohms? If yes, replace CTM. Perform VEHICLE THEFT SECURITY SYSTEM VERIFICATION TEST under VERIFICATION TESTS. If no, repair open in VTSS Indicator Driver circuit. Perform VEHICLE THEFT SECURITY SYSTEM VERIFICATION TEST under VERIFICATION TESTS.
