Vehicle Theft Security System

VEHICLE THEFT SECURITY SYSTEM





The Vehicle Theft Security System (VTSS) is designed to provide perimeter protection against unauthorized use or tampering by monitoring the vehicle door ajar circuits, the power lock and unlock circuits, and the ignition switch circuit. If unauthorized use or tampering is detected, the system responds by pulsing the horn for up to about 3 minutes and flashing the hazard warning lamps for up to about 18 minutes.

The VTSS includes the following major components:

- Door Ajar Switches (4) - A door ajar switch is integral to the door latch mechanism of each front door, as well as the rear doors on quad cab and mega cab vehicles.
- ElectroMechanical Instrument Cluster (2) - The ElectroMechanical Instrument Cluster (EMIC) is also known as the Cab Compartment Node (CCN) in this vehicle. The EMIC/CCN is located in the instrument panel above the steering column opening, directly in front of the driver.
- Ignition Switch (3) - The ignition switch is located on the steering column in the passenger compartment.
- Security Indicator - The security indicator is integral to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN).
- Totally Integrated Power Module (1) - The Totally Integrated Power Module (TIPM) is located in the engine compartment, near the battery.

Hard wired circuitry connects the VTSS components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the VTSS components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
