CHRY - Anti-Theft Systems
Ram Pickup, Ram Van & Ram Wagon
DESCRIPTION
The Vehicle Theft Security System (VTSS) provides an engine
no-run feature, flashes headlights and sounds horn if any door or hood
is opened without using key or remote keyless entry transmitter, or if
battery cables are disconnected then reconnected when system is
activated.
Anti-theft system is controlled by Central Timer Module
(CTM). CTM is located under driver's side of dash panel, right of
steering column. If CTM is faulty, CTM cannot be repaired and must be
replaced.
VTSS is also equipped with a power-up mode. If battery is
disconnected or looses power while VTSS is armed, VTSS system remains
armed when power is restored. A temper alert signal is sounded on
vehicle entry if VTSS was triggered while away from vehicle. Horn will
sound 3 times alerting owner VTSS was triggered.
OPERATION
ARMING PROCEDURE (PASSIVE)
Remove key from ignition. Ensure headlights are off. Lock
doors while open, using power lock switch. Power lock switch will not
operate with key in ignition or headlights on while door is open.
Vehicle Theft Security System (VTSS) will not arm using key in lock
cylinder or mechanical lock button. While system is arming, SECURITY
light will flash rapidly for 15 seconds. Opening any door or turning
the ignition key while light is flashing will abort arming process.
Once arming process is complete, SECURITY light will go out.
ARMING PROCEDURE (ACTIVE)
Pressing Remote Keyless Entry (RKE) transmitter LOCK button
will actively arm Vehicle Theft Security System (VTSS). All doors must\
be closed and ignition switch in OFF position. While system is arming,
SECURITY light will flash rapidly for 15 seconds. Opening any door or
turning the ignition key while light is flashing will abort arming
process. Once arming process is complete, SECURITY light will go out.
DISARMING
Vehicle Theft Security System (VTSS) can be disarmed 2 ways:
unlock vehicle using key in any door and pressing remote keyless entry
transmitter UNLOCK button. If alarm has been set off, either method
can be used to disarm and shut-off horn.
CENTRAL TIMER MODULE (CTM)
Central Timer Module (CTM) is Vehicle Theft Security System
(VTSS) processor. CTM uses the data bus network to allow sharing and
reporting of sensor information. If a door ajar sensor is opened while
VTSS is set, a signal is sent to flash headlights and sound horn. PCM
is also notified through bus network to enable engine no-run feature.
Page 212 of 1691
CTM has remote keyless entry receiver and control logic incorporated.
