Vehicle Theft Security: Notes

The ElectroMechanical Instrument Cluster (EMIC), sometimes referred to as the Cab Compartment Node (CCN), is used to control and integrate many of the functions and features included in the Vehicle Theft Security System (VTSS). In the VTSS, the EMIC/CCN receives inputs indicating the status of the door ajar switches, the liftgate ajar switch and the ignition switch. The EMIC/CCN will process the information from all of these inputs, internally control the security indicator as appropriate, and send electronic messages to the Front Control Module (FCM) over the Controller Area Network (CAN) data bus. The FCM internally controls the output to the hazard warning lamps and sends a control output to energize or de-energize the horn relay as appropriate.

Following are paragraphs describing the operation of each of the VTSS features.
