Dodge Durango (DN). Manual — part 315
Remove the relay (Fig. 3) from the PDC, JB or the
relay and fuse block as described in this group to
perform the following tests:
(1) A relay in the de-energized position should
have continuity between terminals 87A and 30, and
no continuity between terminals 87 and 30. If OK, go
to Step 2. If not OK, replace the faulty relay.
(2) Resistance between terminals 85 and 86 (elec-
tromagnet) should be 75
6 5 ohms. If OK, go to Step
3. If not OK, replace the faulty relay.
(3) Connect a battery to terminals 85 and 86.
There should now be continuity between terminals
30 and 87, and no continuity between terminals 87A
and 30. If OK, test the relay circuits. If not OK,
replace the faulty relay.
SERVICE PROCEDURES
REMOTE KEYLESS ENTRY TRANSMITTER
BATTERY REPLACEMENT
The Remote Keyless Entry (RKE) transmitter case
snaps open and shut for battery access. To replace
the RKE transmitter batteries:
(1) Using a trim stick or another suitable wide
flat-bladed tool, gently pry at the center seam of the
transmitter case halves near the key ring until the
two halves unsnap.
(2) Lift the back half of the transmitter case off of
the transmitter.
(3) Remove the two batteries from the transmitter.
(4) Replace the two batteries with new Duracell
DL2016, or their equivalent. Be certain that the bat-
teries are installed with their polarity correctly ori-
ented.
(5) Align the two transmitter case halves with
each other, and squeeze them firmly together until
they snap back into place.
REMOTE KEYLESS ENTRY TRANSMITTER
PROGRAMMING
To program the Remote Keyless Entry (RKE)
transmitter access codes into the RKE receiver in the
Central Timer Module (CTM) requires the use of a
DRB scan tool. Refer to the proper Diagnostic Proce-
dures manual for more information.

GENERAL INFORMATION
INTRODUCTION
The Vehicle Theft Security System (VTSS) is an
available factory-installed option on this model. Refer
to 8W-39 - Vehicle Theft Security System in Group
8W - Wiring Diagrams for complete circuit descrip-
tions and diagrams.
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 doors and the ignition system. If unautho-
rized use or tampering is detected, the system
responds by sounding the horn, flashing the head-
lamps, and providing an engine no-run feature.
Following are general descriptions of the features
and major components of the VTSS. Refer to the
owner’s manual in the vehicle glove box for more
information on the features, use and operation of the
vehicle theft security system.
ENABLING
If the vehicle is so equipped, the Vehicle Theft
Security System (VTSS) feature is enabled in the
high-line Central Timer Module (CTM) before the
vehicle is shipped from the factory. However, if a
vehicle with VTSS requires CTM replacement, the
VTSS feature must be enabled in the new CTM using
a DRB scan tool. Refer to the Vehicle Theft Security
System menu item on the DRB scan tool for the pro-
cedures.
The VTSS engine no-run feature is disabled when
it is shipped from the factory. This is done by pro-
gramming within the Powertrain Control Module
(PCM). The logic in the PCM prevents the VTSS
engine no-run feature from arming until the engine
start counter within the PCM sees twenty engine
starts. The VTSS no-run feature must be enabled
when the vehicle is received from the assembly plant.
Once the VTSS engine no-run feature has been
enabled, it cannot be disabled unless the PCM is
replaced with a new unit. The same VTSS engine no-
run feature enable logic will apply anytime the PCM
is replaced with a new unit.
ARMING
Passive arming of the Vehicle Theft Security Sys-
tem (VTSS) occurs when the vehicle is exited with
the key removed from the ignition switch, the head-
lamps are turned off, and the doors and liftgate are
locked while they are open using the power lock
switch or locked after they are closed by turning
either front door lock cylinder or the liftgate lock cyl-
inder to the lock position using the key. Passive arm-
ing will not begin until all the doors and the liftgate
are closed. The power lock switch will not function if
the key is in the ignition switch or the headlamps
are turned on with the driver side front door open.
