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.

CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
DESCRIPTION
The speed (cruise) control system is electronically
controlled and vacuum operated. The electronic control is integrated
into the Powertrain Control Module (PCM). System consists of the
following components: Powertrain Control Module (PCM), servo, speed
control switches, vacuum reservoir, vehicle speed sensor, speed
control relay and brake switch.
System controls are located on each side of steering wheel
air bag module and consist of ON/OFF, SET, RESUME/ACCEL, CANCEL AND
COAST buttons. System is designed to operate at speeds above 30 MPH.
OPERATION
SYSTEM CONTROLS
To Set Speed Control
Press ON/OFF button to turn speed control system on.
Accelerate to desired speed (minimum of 35 MPH) and press SET/COAST
button. Vehicle speed will be maintained.
NOTE: Speed control system will automatically disengage when
vehicle speed decreases to less than 35 MPH or increases to
more than 85 MPH.
To Disengage Speed Control
Press brake pedal. Press clutch pedal (M/T). Press CANCEL
button. Press ON/OFF button. If ON/OFF button is used, set speed will
be erased from memory.
To Resume Previous Speed
If set speed has not been erased from memory and vehicle
speed is more than 35 MPH, press RES/ACCEL button.
To Increase Speed
With speed control system on, increase set speed by rapidly
pressing and releasing RES/ACCEL button. Each pressing of button will
cause speed increase of 2 MPH. For example, pressing button 3 times
will increase speed by 6 MPH. To increase speed gradually, hold
RES/ACCEL button down until desired speed is reached. When button is
released, new set speed will be maintained.
To Decrease Speed
With speed control system on, decrease set speed by pressing
SET/COAST button. Vehicle speed will gradually decrease. Releasing
button will set a new speed as long as vehicle speed is still more
than 35 MPH.

voltage. If voltage is less than one volt, go to next step. If voltage
is one volt or more, condition to set FTC is not present at this time.
Test is complete.
2) While observing scan tool, disconnect S/C ON/OFF switch.
If S/C switch voltage changes to 5 volts, replace S/C ON/OFF switch.
Perform TEST VER-4A under VERIFICATION TESTS. If voltage does not
change to 5 volts, go to next step.
3) While observing scan tool, disconnect S/C RESUME/ACCEL
switch. If S/C switch voltage changes to 5 volts, replace S/C
RESUME/ACCEL switch. Perform TEST VER-4A under VERIFICATION TESTS. If
voltage does not change to 5 volts, go to next step.
4) Turn ignition off. Ensure both S/C switches are still
disconnected. Using an ohmmeter, check resistance between S/C switch
connector terminals (S/C switch signal circuit and S/C switch ground
circuit). If resistance is less than 5 ohms, repair short circuit.
Perform TEST VER- 4A under VERIFICATION TESTS. If resistance is 5 ohms
or more, go to next step.
5) Disconnect clockspring 4-pin connector. Clockspring 4-pin
connector is located behind steering wheel. Inspect connector. Clean
or repair as necessary. Using an ohmmeter, check resistance between
ground and S/C switch signal circuit at clockspring connector (Dark
Green/Red wire on all models except Ram Van and Ram Wagon; wire color
is not available for Ram Van and Ram Wagon). If resistance is less
than 5 ohms, repair short to ground. Perform TEST VER-4A under
VERIFICATION TESTS. If resistance is 5 ohms or more, go to next step.
6) Disconnect PCM. Inspect connectors. Clean or repair as
necessary. Using an ohmmeter, check resistance between ground and S/C
switch signal circuit at either S/C switch connector (Dark Green/Red
wire on all models except Ram Van and Ram Wagon; wire color is not
available for Ram Van and Ram Wagon). If resistance is less than 5
ohms, repair short to ground. Perform TEST VER-4A under VERIFICATION
TESTS. If resistance is 5 ohms or more, replace PCM. Perform TEST VER-
4A under VERIFICATION TESTS.
FTC P1683: SPEED CONTROL POWER RELAY CIRCUIT
FTC P1683 will set if Speed Control (S/C) power supply
circuit is open or shorted when S/C is turned on.
Possible Causes:
* Brake switch out of adjustment.
* S/C brake switch output circuit open or shorted.
* Defective S/C servo.
* Defective brake switch.
* S/C vacuum or vent solenoid control circuits open or
shorted.
* Defective PCM.
* Ground circuit open.
* S/C power supply circuit open.
NOTE: For component locations, see COMPONENT LOCATIONS. For
connector terminal identification, see CONNECTOR
IDENTIFICATION. For wiring diagram, see WIRING DIAGRAMS.
NOTE: Ensure brake pedal is not depressed during the following
steps.
1) Turn ignition off. Disconnect S/C servo connector. Inspect
connector. Clean or repair as necessary. Turn ignition on. Using scan
tool, actuate S/C relay. Using a 12-volt test light, probe S/C brake
switch output circuit at S/C servo connector terminal No. 3 (Dark
Blue/Red wire). If test light is illuminated and bright, go to next
