Initialization & Verification
An initialization procedure, included in VTSS, requires that vehicle record 20 engine cranking cycles before allowing VTSS module to function. For this reason, VTSS requires verification. To verify VTSS, perform the following: Open driver's door (all others closed). Remove ignition key. Lock doors with power door lock switch. Close driver's door. If SECURITY light flashes, system is armed and operational. If SECURITY light comes on and stays on with ignition on, the CCD bus communication with PCM may have been lost.
