Intrusion Alarm

The intrusion alarm is an exclusive feature of the export premium version of the VTA, which is only available in certain markets where it is required. When the VTA is armed, the intrusion module uses a hard wired outputs to control an ultrasonic transmitter and receiver which allows the module to monitor the interior of the vehicle for movement. If motion is detected, the intrusion module sends an electronic message to the EMIC and the FCM over the CAN data bus to invoke the visual alarm features, and sends an electronic message to the alarm siren in the engine compartment over a dedicated serial bus to invoke the audible alarm feature.

The motion detect feature of the intrusion module can be disabled by depressing the LOCK button on the RKE transmitter 3 times within 15 seconds during VTA arming, while the security indicator is still flashing rapidly. The VTA provides a single short siren chirp as an audible confirmation that the motion detect disable request has been received.

The intrusion module must be electronically enabled in order for the intrusion alarm to perform as designed. The intrusion alarm function of the module is enabled on vehicles equipped with this option at the factory, but a service replacement module must be configured and enabled by the dealer using a diagnostic scan tool. Refer to the appropriate diagnostic information. The intrusion module monitors the conditions of the transmitter and receiver sensors as well as the siren, and will store fault information in the form of a Diagnostic Trouble Code (DTC) if a system malfunction is detected. The intrusion module may be diagnosed, and any stored DTC can be retrieved using a diagnostic scan tool. Refer to the appropriate diagnostic information.
