CENTRAL TIMER MODULE
DESCRIPTION
The central timer module (CTM) is located beneath
the driver seat. The CTM uses information carried on
the programmable communications interface (PCI)
data bus network along with many hard wired inputs
to monitor many sensor and switch inputs. In
response to those inputs, the circuitry and program-
ming of the CTM allow it to supply the vehicle occu-
pants with audible and visual information, and to
control and integrate many functions and features of
the vehicle through both hard wired outputs and the
transmission of message outputs to other modules in
the vehicle over the PCI data bus.
The features that the CTM supports or controls
include the following:
²Central Locking- The CTM on vehicles
equipped with the optional Vehicle Theft Security
System (VTSS) includes a central locking/unlocking
feature.
²Enhanced Accident Response- The CTM pro-
vides an optional enhanced accident response fea-
ture. This is a programmable feature.
²Panic Mode- The CTM provides support for
the optional RKE system panic mode including horn,
headlamp, and park lamp flash features.
²Power Lock Control- The CTM provides the
optional power lock system features, including sup-
port for the automatic door lock and door lock inhibit
modes.²Programmable Features- The CTM provides
support for certain programmable features.
²Remote Keyless Entry- The CTM provides
the optional Remote Keyless Entry (RKE) system fea-
tures, including support for the RKE Lock (with
optional horn and park lamps flash), Unlock (with
park lamps flash, driver-door-only unlock, and
unlock-all-doors), Panic, and illuminated entry
modes, as well as the ability to be programmed to
recognize up to four RKE transmitters. The RKE
horn, driver-door-only unlock, and unlock-all-doors
features are programmable.
²Vehicle Theft Security System- The CTM
provides control of the optional Vehicle Theft Secu-
rity System (VTSS) features, including support for
the central locking/unlocking mode and control of the
Security indicator in the instrument cluster.
Hard wired circuitry connects the CTM to the elec-
trical system of the vehicle. Refer to the appropriate
wiring information.
Many of the features in the vehicle controlled or
supported by the CTM are programmable using the
DRBIIItscan tool. However, if any of the CTM hard-
ware components are damaged or faulty, the entire
CTM unit must be replaced. The hard wired inputs
or outputs of all CTM versions can be diagnosed
using conventional diagnostic tools and methods;
however, for diagnosis of the CTM or the PCI data
bus, the use of a DRBIIItscan tool is required. Refer
to the appropriate diagnostic information.

LAMPS/LIGHTING - INTERIOR
DESCRIPTION
The interior lighting for this model includes the
following standard and optional incandescent interior
lamps and controls:
²Ash Receiver/Cigar Lighter Lamp- An avail-
able ash receiver/cigar lighter lamp is secured by an
integral mount to the outside of the cigar lighter halo
ring. A single lamp serves to illuminate both the
translucent halo ring and the ash receiver.
²Cargo/Dome Lamp- Several cargo/dome lamp
units located overhead in both the front and rear of
the vehicle interior are standard equipment. These
lamps feature a single incandescent bulb. An optional
version of these lamps includes an integral three-po-
sition switch that protrudes through the lamp lens.
²Cargo Lamp Switch- Toggle-type remote
cargo lamp switches located in the accessory switch
bezel in the center of the instrument panel, on the
back side of the cargo compartment bulkhead panel,
and on the rear cargo door pillar are an available
option on all van models. The instrument panelswitch has two Light-Emitting Diode (LED) units,
one for illumination and a second that provides an
indication. The switches mounted in the cargo com-
partment also have two LED units, but only the indi-
cation LED unit is functional in this application.
²Dome/Reading Lamp- An optional equipment
dome/reading lamp unit is located in the windshield
header area between the driver and passenger sun
visors. This lamp features two incandescent bulbs,
one dome lamp bulb and a second, dedicated reading
lamp bulb. An integral four-position switch protrudes
through the lamp lens.
²Dome Lamp/Intrusion Sensor- An optional
equipment dome lamp/intrusion sensor unit is
located overhead in the vehicle interior. This lamp
features four incandescent bulbs, two for dome lamps
and two for dedicated right and left reading lamps.
This lamp has two integral three-position switches,
one to control interior lamp operation and one to con-
trol reading lamp operation. This lamp also houses
three intrusion sensors that are part of an optional
vehicle theft security system.
²Door Jamb Switch- A door jamb switch for
each front door is standard equipment on all models.
VALAMPS/LIGHTING - INTERIOR 8L - 25

A door jamb switch for each sliding side door and the
right rear door is standard equipment on wagon mod-
els. The sliding and rear door jamb switches are not
available for van models.
²Entry/Exit Lamp- An entry/exit lamp to illu-
minate each front and sliding side door step well is
optional equipment on wagon models.
²Time Delay Relay- Vehicles equipped with the
optional remote cargo lamp switches also have a time
delay relay located in the electrical center within the
driver side front seat riser.
Hard wired circuitry connects the interior lighting
system components to the electrical system of the
vehicle. These hard wired circuits are integral to sev-
eral 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 interior lighting
system 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 infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-
tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
OPERATION
The interior lighting systems can be divided into
two general classifications based upon the circuit
that controls their operation: The interior lighting
circuit, or the exterior lighting circuit. The hard
wired circuits and components of the interior lighting
systems may be diagnosed and tested using conven-
tional diagnostic tools and procedures.
INTERIOR LIGHTING CIRCUIT
Depending upon the vehicle model (van or wagon)
and the selected vehicle options the interior lighting
circuit may include dome/cargo lamps located over-
head in the front and rear of the vehicle, a dome/
reading lamp located in the header area above the
windshield between the sun visors, and entry/exit
lamps located in the front and sliding side door step
wells.
WAGON MODELS
In all wagon models, the lamps in the interior
lighting circuit are provided with battery current at
all times by a fuse in the fuse block beneath the
steering column. The front, side, and rear door jamb
switches control a ground path for each of these
lamps, except for the optional reading lamp. If the
lamp has an optional integral switch, that switch has
three separate positions. The first position provides aground path independent of the door jamb switches
to turn the lamp On. The second, or center position
allows the door jamb switches to control the lamp.
The third position segregates that lamp from the
door jamb switch input, turning the lamp Off. In the
case of the optional dome/reading lamp, the integral
lamp switch has a fourth position which will illumi-
nate only the reading lamp bulb.
VAN MODELS
Unless a van model is equipped with an optional
remote cargo lamp switch, all of the lamps in the
interior lighting circuit operate the same way as the
wagon models except that there are only two door
jamb switches, one for each front door. If the vehicle
is equipped with an optional remote cargo lamp
switch, the lamps in the rear of the vehicle on the
interior lighting circuit are provided with battery
current by the time delay relay. The time delay relay
is a smart relay containing active electronic elements
that comprise an electronic timer logic circuit. When
the remote cargo lamp switches provide the proper
input to the time delay relay, the relay logic responds
by energizing the relay control coil. The energized
relay control coil provides battery current to all of
the lamps on the rear interior lighting circuit and to
the indicator Light-Emitting Diode (LED) units in
the remote cargo switches causing each to illuminate.
If a remote cargo lamp switch remains On for more
than about fifteen minutes, the time delay relay will
then automatically de-energize the rear interior
lighting circuits until the remote cargo lamp switch
is cycled Off and then back On.
EXTERIOR LIGHTING CIRCUIT
The exterior lighting circuit provides battery cur-
rent to the optional ash receiver/cigar lighter lamp
and to the illumination Light-Emitting Diode (LED)
unit within the remote cargo lamp switch in the
instrument panel accessory switch bezel whenever
the exterior lamps are turned On.

CENTRAL LOCKING
The central locking system locks all vehicle doors if
any door is locked from the inside or mechanically
locked with the key from the outside. the master door
lock switch on the instrument panel enables the
operator to lock/unlock all doors.
REMOTE KEYLESS ENTRY
The SKREEM is a combination of the Remote Key-
less Entry (RKE) module and the Sentry Key Immo-
bilizer (SKIM) module. It is located behind the
instrument cluster and has an antenna that mounts
to the A-pillar.
AUTO DOOR LOCKS
Whenever the engine is started, the CTM receivers
a message to lock all doors except the drivers door.
This is accomplished through a relay. The relay is
controlled by the Instrument Cluster which receives
a command from the ECM.

VEHICLE THEFT SECURITY
DESCRIPTION
An anti-theft alarm with battery powered horn is
available as an option and includes interior monitor-
ing, anti-tow away protection and rear window mon-
itoring based on the heater wires. The alarm is
automatically activated when the central locking sys-
tem is operated.
The alarm will sound when any of the following
occur:
²A door is opened
²A door is unlocked from inside the vehicle
²The hood is opened
²The vehicle is raised at the front or rear
²The trailer wire harness is disconnected
²Movements inside the vehicle
²The central locking is unlocked by a key at any
other door than the driver's door
The alarm is functional about 30 seconds after the
vehicle is locked using the RKE transmitter or the
key in the driver's door. Activation is indicated by the
indicator lights flashing three times and the warning
lamp flashing in the switch. If persons or animals
remain in the locked vehicle, the operator should
switch off the interior monitor to avoid a false alarm.
OPERATION
The anti-theft alarm is activated/deactivated by
locking/unlocking the vehicle with the remote trans-
mitter or with the key at the driver's door. The key
must be held in the locking position for more than
two seconds. Activation is indicated by the turn sig-
nal lights flashing once. Unlocking the vehicle at one
of the other doors will trigger an alarm.The interior monitoring system included in the
anti-theft alarm is based on ultrasonics and triggers
an alarm if an object intrudes the interior of the
vehicle or if any movement is detected inside the
vehicle. For proper and effective protection, all win-
dows and the sunroof must be closed.
To switch off the interior monitoring system and /
or the anti-tow away protection, a switch with LED
indicator light is provided in the switch panel. An
alarm button enables the operator to trigger an
alarm manually and to lock all doors if they are
closed. Triggering an alarm makes the horn sound
and the turn signals flash until the alarm is switched
off.
The anti-theft alarm control unit includes a gradi-
ent indicator as anti-tow away protection. The gradi-
ent indicator triggers an audible and visual alarm if
the vehicle is lifted (to tow away or to remove the
wheels). The alarm remains effective even if the bat-
tery is disconnected as the horn is powered by its
own battery. The interior monitoring system should
be switched off if people and/or animals are left in
the vehicle.
DIAGNOSIS AND TESTING - VEHICLE THEFT
SECURITY
Any diagnosis of the Vehicle Theft Security
system should begin with the use of the DRB
IIItdiagnostic tool. For information on the use
of the DRB IIIt, refer to the appropriate Diag-
nostic Service Manual.

SENTRY KEY IMMOBILIZER
The Sentry Key Immobilizer System (SKIS)
authenticates an electronically coded Transponder
Key placed into the ignition and sends a valid/invalid
key message to the Engine Control Module (ECM)
based upon the results. The ªVALID/INVALID KEYº
message communication is performed using a rolling
code algorithm. A ªVALID KEYº message must be
sent to the ECM within two seconds of ignition ON
to free the engine from immobilization. This Control-
ler Area Network (CAN) data bus message is sent to
the ECM after first going through the SKREEM. The
SKREEM is located behind the instrument cluster
and has a separately mounted antenna ring mounted
around the ignition cylinder (Fig. 3) which picks up
the transponder key signal.
REMOTE KEYLESS ENTRY (RKE)
The RKE transmitter uses radio frequency signals
to communicate with the Sentry Key Remote Entry
Module (SKREEM). The SKREEM is hardwired to
the Central Timer Module (CTM). When the operator
presses a button on the transmitter, it sends a spe-
cific request to the SKREEM. In turn, the SKREEM
sends the appropriate request to the CTM to unlock
the vehicle doors.
OPERATION
SENTRY KEY IMMOBILIZER
The Sentry Key Remote Entry Module (SKREEM)
receives an encrypted Radio Frequency (RF) signal
from the transponder key which is read by the
remotely mounted antenna ring at the ignition cylin-
der. The SKREEM then decrypts the signal and
broadcasts the requested remote commands to theappropriate modules in the vehicle over the Control-
ler Area Network (CAN) data bus. A valid transpon-
der key ID must be incorporated into the RF signal
in order for the SKREEM to pass the message on to
the appropriate modules.
Automatic transponder key synchronization is done
by the SKREEM if a valid transponder key is
inserted into the ignition cylinder, and the ignition is
turned ON. This provides a maximum operation win-
dow for RKE functions.
Each Sentry Key Remote Entry System (SKREES)
consists of a SKREEM, an antenna ring mounted
around the ignition cylinder, and a transponder key.
Each system has a secret key code unique to that
system. The secret key is electronically coded in the
SKREEM and in all programmed transponder keys.
It is used for immobilization and RKE functions for
data security. In addition, each transponder key will
have a unique identification.
REMOTE KEYLESS ENTRY
After pressing the lock button on the RKE trans-
mitter, all of the door locks will lock, the illuminated
entry will turn off (providing all doors are closed),
and the VTSS (if equipped) will arm. After pressing
the unlock button, on the RKE transmitter, one time,
the driver door lock will unlock, the illuminated
entry will turn on the courtesy lamps, and the VTSS
(if equipped) will disarm. After pressing the unlock
button a second time, the remaining door locks will
unlock.
The SKREEM is capable of retaining up to 8 indi-
vidual access codes (8 transmitters). If the PRNDL is
in any position except park, the SKREEM will dis-
able the RKE. Use the DRBIIItor the customer pro-
gramming method to program the RKE system.
However, the SKREEM will only allow RKE pro-
gramming when the ignition is in the ON position,
the PRNDL is in park position, and the VTSS (if
equipped) is disarmed.
REMOVAL
SENTRY KEY REMOTE ENTRY MODULE
(1) Open hood, disconnect and isolate the battery
negative cable.
(2) Wait two minutes for the system reserve capac-
itor to discharge before beginning any system or com-
ponent service.
(3) Remove top cover - cluster (Refer to 23 -
BODY/INSTRUMENT PANEL/TOP COVER - CLUS-
TER - REMOVAL).

VAVEHICLE THEFT SECURITY 8Q - 3
SENTRY KEY REMOTE ENTRY MODULE (Continued)

TRANSPONDER KEY
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) which
communicates with the Sentry Key Remote Entry
Module (SKREEM), uses a transponder chip that is
integral to each key fob (Fig. 6). Ignition keys are
supplied with the vehicle when it is shipped from the
factory. The transponder chip is located within the
Remote Keyless Entry (RKE) fob.
OPERATION
Each Sentry Key has a unique transponder identi-
fication code permanently programmed into it by themanufacturer. Likewise, the Sentry Key Remote
Entry Module (SKREEM) has a unique9Secret Key9
code programmed into it by the manufacturer as
well. When a Sentry Key is programmed into the
memory of the SKREEM, the SKREEM stores the
transponder identification code from the Sentry Key,
and the Sentry Key learns the9Secret Key9code from
the SKREEM. Once the Sentry Key learns the
9Secret Key9code of the SKREEM, it is also perma-
nently programmed into the transponder's memory.
The Sentry Key's transponder is within the range
of the SKREEM's transponder ring when it is
inserted into the ignition lock cylinder. When the
ignition switch is turned to the ON position, the
SKREEM communicates with the Sentry Key via a
radio frequency (RF) signal. The SKREEM deter-
mines if a valid key is present based on the informa-
tion it receives from the Sentry Key. If a valid key is
detected, that fact is communicated to the Engine
Control Module (ECM) via the Controller Area Net-
work (CAN) data bus and the vehicle is allowed to
continue running. If an invalid key is received by the
ECM or no status at all is communicated, the vehicle
will stall after two (2) seconds of running. The indi-
cator light will be flashing at this point. The Sentry
Key's transponder can not be repaired. If it is faulty
or damaged, it must be replaced.
Common communication problems:
²Two transponder keys too close together.
²Speed Pass too close to transponder key.
Solid indicator that there is a system failure.
²Loss of ECM communication.
²Failed transponder ring circuit.
