The VTSS includes the following major components, which are described in further detail elsewhere in this service
information:
•
Door Cylinder Lock Switch (4) - A cylinder lock switch is located on the back of the lock cylinder on the
driver side front door. (Refer to 8 - ELECTRICAL/VEHICLE THEFT SECURITY/DOOR CYLINDER LOCK
SWITCH - DESCRIPTION).
•
Door Ajar Switches (5) - A door ajar switch is integral to the door latch mechanism of each front and rear
door. (Refer to 8 - ELECTRICAL/LAMPS/LIGHTING - INTERIOR/DOOR AJAR SWITCH - DESCRIPTION).
•
Front Control Module (1) - The Front Control Module (FCM) is integral to the Integrated Power Module (IPM).
The FCM/IPM is located in the engine compartment, near the battery and the Power Distribution Center (PDC).
(Refer to 8 - ELECTRICAL/POWER DISTRIBUTION - DESCRIPTION).
•
Horn Relay - The horn relay is located in the Power Distribution Center (PDC) in the engine compartment
near the battery. (Refer to 8 - ELECTRICAL/HORN/HORN RELAY - DESCRIPTION).
•

(Refer to 8 - ELECTRICAL/IGNITION CONTROL/IGNITION SWITCH - DESCRIPTION).
•
Instrument Cluster (2) - The ElectroMechanical Instrument Cluster (EMIC) is also known as the Cab Control
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. (Refer to 8 - ELECTRICAL/INSTRUMENT CLUSTER - DESCRIPTION).
•
Security Indicator - The security indicator is integral to the instrument cluster. (Refer to 8 - ELECTRICAL/
INSTRUMENT CLUSTER/SECURITY INDICATOR - DESCRIPTION).
Hard wired circuitry connects the VTSS components to the electrical system of the vehicle. These hard wired cir-
cuits 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 VTSS components through the use of a combina-
tion 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 loca-
tion views for the various wire harness connectors, splices and grounds.
