SLIDING DOOR CONTROL
MODULE
DESCRIPTION
Vehicles equipped with a power sliding door utilize
a sliding door control module. The sliding door con-
trol module is located behind the sliding door trim
panel in the center of the door, just above the sliding
door motor (Fig. 15). This module controls the opera-
tion of the door through the Programmable Commu-
nication Interface (PCI) J1850 data bus circuit and
the Body Control Module. The sliding door control
module contains software technology which enables it
to detect resistance to door travel and to reverse door
travel in order to avoid damage to the door or to
avoid possible personal injury if the obstruction is a
person. This feature functions in both the opening
and closing cycles. If the power sliding door system
develops any problems the control module will store
and recall Diagnostic Trouble Codes (DTC). The use
of a diagnostic scan tool, such as the DRB IIItis
required to read and troubleshoot these trouble
codes. The sliding door control module can be
reflashed if necessary. Refer to the latest Technical
Service Bulletin (TSB) Information for any updates.
The power door control module is a replaceable
component and cannot be repaired, if found to be
faulty it must be replaced. Consult your MoparŸ
parts catalog for a specific part number.
OPERATION
The power sliding door control module serves as
the main computer for the power sliding side doorsystem. All power door functions are processed
through the power door control module and/or the
vehicles body control module (BCM). At the start of a
power open command, a signal is sent to the BCM
and then to the power door control module via the
J1850 data bus circuit. This signal, generated by any
of the power door command switches, tells the power
door control module to activate a power latch release,
engage the clutch assembly and drive the door into
the full open position. If an obstacle is felt during
this power open cycle, the module will reverse direc-
tion and close the door. This process is also enabled
during a power close cycle. This process will repeat
three times, and if a fourth obstacle is detected, the
door will go into full manual mode. Once the full
open position is obtained, a hold open latch assembly
mounted full open switch tells the control module
that the door has reached the full open position. If
the power sliding door system develops any problems
the control module will store and recall Diagnostic
Trouble Codes (DTC). The use of a diagnostic scan
tool, such as the DRB IIItis required to read and
troubleshoot these trouble codes.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.

BODY CONTROL MODULE
DESCRIPTION
The Body Control Module (BCM) is located in the
passenger compartment, attached to the bulkhead
underneath the left side of the instrument panel. The BCM utilizes integrated circuitry and informa-
tion carried on the Programmable Communications
Interface (PCI) data bus network along with many
hard wired inputs to monitor many sensor and
switch inputs throughout the vehicle. In response to
those inputs, the internal circuitry and programming
of the BCM allow it to control and integrate many
electronic functions and features of the vehicle
through both hard wired outputs and the transmis-
sion of electronic message outputs to other electronic
modules in the vehicle over the PCI data bus.
OPERATION
The Body Control Module (BCM) supplies vehicle
occupants with visual and audible information and
controls various vehicle functions. To provide and
receive information, the BCM is interfaced to the
vehicle's serial bus communications network, referred
to as the Programmable Communications Interface
(PCI) bus. This network consists of the;
² Powertrain Control Module (PCM)
² Transmission Control Module (TCM)
² Mechanical Instrument Cluster (MIC)
² Occupant Restraint Controller (ORC)
² Compass/Mini-Trip Computer (CMTC)
² Electronic Vehicle Information Center (EVIC)
² Controller Antilock Brake (CAB)
² HVAC Control Module
² Sliding Door Control Modules (driver and pas-
senger side doors) ² Power Liftgate Module (PLG) ²
Audio system equipped with RAZ, RBU, RBK,
and RBB radios. ² Sentry Key Remote Entry Module (SKREEM).
² Side Impact Airbag Control Module (SIACM)
² Memory Seat Module (MSM)
² Sentry Key Immobilizer Module (SKIM)
The BCM is operational when battery power is
supplied to the module. The BCM provides the following features:
² Power Door Locks
² Automatic Door Locks
² Battery Protection - The BCM will automatically
turn off all exterior lamps after 3 minutes, and all
interior lamps after 15 minutes after the ignition is
turned off, if they are not turned off by the driver. ² Chime Control
² Compass/Mini-Trip support.
² Interior Lighting (Courtesy/Reading Lamps)
² BCM Diagnostic Reporting
² Electronic Liftgate Release (with Power Door
Locks) ² Exterior Lighting
² Headlamp Time Delay (with/without Automatic
Headlamps) ² Illuminated Entry
² Fade to Off Interior Lamps - This feature dims
the interior lighting (courtesy lamps) gradually if the
BCM does not receive any new inputs that would
cause the interior lamps to remain on. ² Pulse Width Modulated Instrument Panel Dim-
ming ² Door Lock Inhibit - This feature disables the
door lock functions if the key is in the ignition and
either front door is ajar. Pressing the Remote Keyless
Entry (RKE) lock/unlock button under these condi-
tions result in normal lock/unlock activation. The BCM has the ability to LEARN additional fea-
tures in the vehicle, provided the appropriate switch
input and PCI data bus messages are received. Refer
to the LEARNED FEATURES table.

When replacing a BCM there are three modules
available: ² Base
² Midline
² RG - Export
The Midline controller is used on vehicles that
have Power Door Locks. If a vehicle is equipped with
the Vehicle Theft Security System, the Midline con-
troller becomes a Premium when the theft feature is
enabled.
CAUTION: Do not swap Body Control Modules
between vehicles or body controller's off the shelf.
The BCM has internal diagnostic capability that
assists in diagnosing the system error. When an
OPEN or a SHORT circuit exists, the diagnostic tool
can be used to read the BCM faults. The faults are
very descriptive in identifying the appropriate fea-
ture that has faulted. The only two faults that the BCM logs that con-
clude the replacement of a BCM are faults; ² # 01 - Internal BCM failure (replace BCM)
² # 1F - J1850 Internal Hardware Failure (replace
BCM) Otherwise the appropriate diagnostic procedures
for each of the features should be taken when the
BCM logs a fault.REMOVAL

DESCRIPTION) section for more DTC information.
The Check Gauges Lamp (if equipped) or Battery
Lamp monitors:charging system voltage,engine
coolant temperature and engine oil pressure. If an
extreme condition is indicated, the lamp will be illu-
minated. The signal to activate the lamp is sent via
the PCI bus circuits. The lamp is located on the
instrument panel. Refer to the Instrument Cluster
section for additional information.
(If equipped with inlet air temperature sensor) The
PCM uses the inlet air temperature sensor to control
the charge system voltage. This temperature, along
with data from monitored line voltage, is used by the
PCM to vary the battery charging rate. The system
voltage is higher at cold temperatures and is gradu-
ally reduced as the calculated battery temperature
increases.
The ambient temperature sensor is used to control
the battery voltage based upon ambient temperature
(approximation of battery temperature). The PCM
maintains the optimal output of the generator by
monitoring battery voltage and controlling it to a
range of 13.5 - 14.7 volts based on battery tempera-
ture. The system target voltage is 13.5 ± 14.7 volts.
However the actual voltage go below this during
heavy electrical loads and generator speeds. Also the
actual voltage can be lower than the target voltage
between the battery and the battery voltage sense
circuit, approximately 0.2 Ð 0.3 volts.
DIAGNOSIS AND TESTING - ON-BOARD
DIAGNOSTIC SYSTEM
The Powertrain Control Module (PCM) monitors
critical input and output circuits of the charging sys-
tem, making sure they are operational. A Diagnostic
Trouble Code (DTC) is assigned to each input and
output circuit monitored by the OBD system. Some
circuits are checked continuously and some are
checked only under certain conditions.
If the OBD system senses that a monitored circuit
is bad, it will put a DTC into electronic memory. The
DTC will stay in electronic memory as long as the
circuit continues to be bad. The PCM is programmed
to clear the memory after 40 good trip if the problem
does not occur again.
DIAGNOSTIC TROUBLE CODES
A DTC description can be read using the DRBIIIt
scan tool. Refer to the appropriate Powertrain Diag-
nostic Procedures manual for information.
A DTC does not identify which component in a cir-
cuit is bad. Thus, a DTC should be treated as a
symptom, not as the cause for the problem. In some
cases, because of the design of the diagnostic test
procedure, a DTC can be the reason for another DTCto be set. Therefore, it is important that the test pro-
cedures be followed in sequence, to understand what
caused a DTC to be set.
ERASING DIAGNOSTIC TROUBLE CODES
The DRBIIItScan Tool must be used to erase a
DTC.
The following procedures may be used to diagnose
the charging system if:
²the check gauges lamp or battery lamp is illumi-
nated with the engine running
²the voltmeter (if equipped) does not register
properly
²an undercharged or overcharged battery condi-
tion occurs.
Remember that an undercharged battery is often
caused by:
²accessories being left on with the engine not
running
²a faulty or improperly adjusted switch that
allows a lamp to stay on. Refer to Ignition-Off Draw
Test (Refer to 8 - ELECTRICAL/BATTERY SYSTEM/
BATTERY - STANDARD PROCEDURE)
²loose generator belt.
INSPECTION
The Powertrain Control Module (PCM) monitors
critical input and output circuits of the charging sys-
tem, making sure they are operational. A Diagnostic
Trouble Code (DTC) is assigned to each input and
output circuit monitored by the On-Board Diagnostic
(OBD) system. Some charging system circuits are
checked continuously, and some are checked only
under certain conditions.
Refer to Diagnostic Trouble Codes in; Powertrain
Control Module; Electronic Control Modules for more
DTC information. This will include a complete list of
DTC's including DTC's for the charging system.
To perform a complete test of the charging system,
refer to the appropriate Powertrain Diagnostic Proce-
dures service manual and the DRBIIItscan tool.
Perform the following inspections before attaching
the scan tool.
(1) Inspect the battery condition. Refer to the Bat-
tery section (Refer to 8 - ELECTRICAL/BATTERY
SYSTEM - DIAGNOSIS AND TESTING) for proce-
dures.
(2) Inspect condition of battery cable terminals,
battery posts, connections at engine block, starter
solenoid and relay. They should be clean and tight.
Repair as required.
(3) Inspect all fuses in both the fuseblock and
Power Distribution Center (PDC) or IPM (if
equipped) for tightness in receptacles. They should be
properly installed and tight. Repair or replace as
required.
