Vehicle Theft Security: Operation: Enabling

The Body Control Module is shipped with the VTSS feature enabled state. Upon enabling the VTSS on the BCM, it will start transmitting the OK to start message to the Powertrain Control Module. At this time the visual alarm outputs the headlamps and marker lamps will function. However the audio alarm output the horn and engine disable portion of the VTSS will not function until there has been four consecutive engine run cycles. When this has occurred the total VTSS will function.

If during alarm being set the BCM receives a request from the RKE module to enter PANIC mode the BCM will cancel the alarm, return VTSS armed state and then perform the RKE PANIC feature.
