DIAGNOSIS AND TESTING - INSTRUMENT
CLUSTER
The hard wired inputs to and outputs from the
instrument cluster may be diagnosed and tested
using conventional diagnostic tools and procedures.
Refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
If the instrument cluster is completely inoperative,
be certain to check the fused B(+) circuit fuses and
wiring for the instrument cluster. If the cluster gen-
eral illumination is inoperative, be certain to check
the instrument lighting fuse and the input circuit to
the instrument cluster from the exterior lighting cir-
cuitry of the multi-function switch on the steering
column.
Conventional diagnostic methods may not prove
conclusive in the diagnosis of the instrument cluster.
In order to obtain conclusive testing of the instru-
ment cluster, the Controller Area Network (CAN)
data bus network and all of the electronic modules
that provide inputs to or receive outputs from theinstrument cluster must also be checked. The most
reliable, efficient, and accurate means to diagnose
the instrument cluster, the CAN data bus network,
and the electronic modules that provide inputs to or
receive outputs from the instrument cluster requires
the use of a DRBIIItscan tool and the appropriate
diagnostic information. The DRBIIItscan tool can
provide confirmation that the CAN data bus network
is functional, that all of the modules are sending and
receiving the proper electronic messages over the
CAN data bus, and that the instrument cluster is
receiving the proper hard wired inputs and respond-
ing with the proper hard wired outputs needed to
perform its many functions.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, DRIVER AIRBAG,
PASSENGER AIRBAG, SEAT BELT TENSIONER, OR
INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. DISCONNECT AND ISOLATE THE BAT-
TERY NEGATIVE (GROUND) CABLE, THEN WAIT
TWO MINUTES FOR THE SYSTEM CAPACITOR TO
DISCHARGE BEFORE PERFORMING FURTHER
DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE
WAY TO DISABLE THE SUPPLEMENTAL
RESTRAINT SYSTEM. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCI-
DENTAL SUPPLEMENTAL RESTRAINT DEPLOY-
MENT AND POSSIBLE PERSONAL INJURY.

DESCRIPTION
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.
ACCIDENT RESPONSE
The CTM is hardwired to the Airbag Control Mod-
ule through the Enhanced Accident Report Driver cir-
cuit. Anytime the vehicles airbags are deployed, the
CTM will unlock all doors and a ªcrashº DTC will be
stored in memory. The door locks will be inoperative
until that code is cleared.
DOOR LOCK MOTOR
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the door trim panel.
(3) Remove the door lock.
(4) Remove the door lock motor from the door lock.
INSTALLATION
(1) Install the door lock motor to the door lock.
(2) Install the door lock.
(3) Install the door trim panel.
(4) Connect the battery negative cable.

WARNING: USE EXTREME CARE TO PREVENT ANY
FOREIGN MATERIAL FROM ENTERING THE DRIVER
AIRBAG, OR BECOMING ENTRAPPED BETWEEN
THE DRIVER AIRBAG CUSHION AND THE DRIVER
AIRBAG TRIM COVER. FAILURE TO OBSERVE THIS
WARNING COULD RESULT IN OCCUPANT INJURIES
UPON AIRBAG DEPLOYMENT.
WARNING: THE DRIVER AIRBAG TRIM COVER
MUST NEVER BE PAINTED. REPLACEMENT AIR-
BAGS ARE SERVICED WITH TRIM COVERS IN THE
ORIGINAL COLORS. PAINT MAY CHANGE THE WAY
IN WHICH THE MATERIAL OF THE TRIM COVER
RESPONDS TO AN AIRBAG DEPLOYMENT. FAIL-
URE TO OBSERVE THIS WARNING COULD RESULT
IN OCCUPANT INJURIES UPON AIRBAG DEPLOY-
MENT.
(1) Position the driver airbag close enough to the
steering wheel to reconnect the clockspring driver
airbag pigtail wire connector at the back of the air-
bag housing.
(2) When installing the driver airbag, reconnect
the clockspring driver airbag pigtail wire connector
to the airbag inflator connector receptacle by press-
ing straight in on the connector (Fig. 21). You can be
certain that the connector is fully engaged by listen-
ing carefully for a distinct, audible click as the con-
nector snaps into place.
(3) Carefully position the driver airbag in the
steering wheel. Be certain that the clockspring pig-
tail wire and horn switch wires in the steering wheel
hub area are not pinched between the driver airbag
and the horn switch armature.
(4) From the underside of the steering wheel,
install and tighten the two screws that secure the
driver airbag to the horn switch armature within the
hub cavity of the steering wheel. Tighten the screws
to 6 N´m (53 in. lbs.).
(5) Do not reconnect the battery negative cable at
this time. The supplemental restraint system verifi-
cation test procedure should be performed following
service of any supplemental restraint system compo-
nent. (Refer to 8 - ELECTRICAL/RESTRAINTS -
STANDARD PROCEDURE - VERIFICATION TEST).
FRONT SEAT BELT &
RETRACTOR
REMOVAL
The following procedure is for replacement of a
faulty or damaged front seat belt and retractor unit,
which includes a seat belt tensioner for the driver
side as standard equipment. Vehicles equipped withan optional passenger airbag also have a seat belt
tensioner for the passenger side. (Refer to 8 - ELEC-
TRICAL/RESTRAINTS/SEAT BELT TENSIONER -
DESCRIPTION). If the seat belt or retractor is faulty
or damaged, but the seat belt tensioner is not
deployed, review the recommended procedures for
handling non-deployed supplemental restraints.
(Refer to 8 - ELECTRICAL/RESTRAINTS - STAN-
DARD PROCEDURE - HANDLING NON-DE-
PLOYED SUPPLEMENTAL RESTRAINTS). If the
seat belt tensioner has been deployed, review the rec-
ommended procedures for service after a supplemen-
tal restraint deployment before removing the front
seat belt and retractor from the vehicle. (Refer to 8 -
ELECTRICAL/RESTRAINTS - STANDARD PROCE-
DURE - SERVICE AFTER A SUPPLEMENTAL
RESTRAINT DEPLOYMENT).
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, DRIVER AIRBAG,
PASSENGER AIRBAG, SEAT BELT TENSIONER, OR
INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. DISCONNECT AND ISOLATE THE BAT-
TERY NEGATIVE (GROUND) CABLE, THEN WAIT
TWO MINUTES FOR THE SYSTEM CAPACITOR TO
DISCHARGE BEFORE PERFORMING FURTHER
DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE
WAY TO DISABLE THE SUPPLEMENTAL
RESTRAINT SYSTEM. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCI-
DENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
WARNING: DURING AND FOLLOWING ANY SEAT
BELT SERVICE, CAREFULLY INSPECT ALL SEAT
BELTS, BUCKLES, MOUNTING HARDWARE,
RETRACTORS, AND ANCHORS FOR PROPER
INSTALLATION, OPERATION, OR DAMAGE.
REPLACE ANY BELT THAT IS CUT, FRAYED, OR
TORN. STRAIGHTEN ANY BELT THAT IS TWISTED.
TIGHTEN ANY LOOSE FASTENERS. REPLACE ANY
BELT THAT HAS A DAMAGED OR INOPERATIVE
BUCKLE OR RETRACTOR. REPLACE ANY BELT
THAT HAS A BENT OR DAMAGED LATCH PLATE
OR ANCHOR PLATE. NEVER ATTEMPT TO REPAIR
A SEAT BELT COMPONENT. ALWAYS REPLACE
DAMAGED OR FAULTY SEAT BELT COMPONENTS
WITH THE CORRECT, NEW AND UNUSED
REPLACEMENT PARTS LISTED IN THE
DAIMLERCHRYSLER MOPAR PARTS CATALOG.
(1) Move the front seat to its most forward position
for easiest access to the B-pillar trim.
