DESCRIPTION
Exterior sheet metal components make up the
exterior of the vehicle. Some exterior metal systems
are welded assemblies, such as doors and hoods.
Some exterior trim items are made of composite.
OPERATION
The exterior is finished in various metal stampings
and composite moldings. These assemblies give the
vehicle a finished appearance and protect the occu-
pants from the elements. Some components are partof the energy absorbing system used to protect the
occupants in collisions. The exterior sheet metal is
repairable and adjustable for fit and finish. Welded
and bonded component systems are adjustable as a
system. Trim components made of composite are
stamped with the type of material used. Daimler-
Chrysler uses various fasteners to retain trim items.
At times, it is not possible to remove trim items
without damaging the fastener. If it is not possible to
remove an item without damaging a component, cut
or break the fasteners and use new ones when
installing the component.

EMISSIONS CONTROL
DESCRIPTION - DIESEL
Two different modules are used for powertrain con-
trol with the diesel engine. The Powertrain Control
Module (PCM) is used primarily for charging system,
transmission, A/C compressor clutch operation and
speed control functions. The Engine Control Module
(ECM) is used to control thefuel and emissions
systems.The PCM is located in the right/rear of
engine compartment (Fig. 1). The ECM is bolted to
the left side of the engine cylinder block (Fig. 2).
DESCRIPTION - STATE DISPLAY TEST MODE
The switch inputs to the Powertrain Control Mod-
ule (PCM) have two recognized states; HIGH and
LOW. For this reason, the PCM cannot recognize the
difference between a selected switch position versus
an open circuit, a short circuit, or a defective switch.
If the State Display screen shows the change from
HIGH to LOW or LOW to HIGH, assume the entire
switch circuit to the PCM functions properly. Connectthe DRB scan tool to the data link connector and
access the state display screen. Then access either
State Display Inputs and Outputs or State Display
Sensors.
DESCRIPTION - CIRCUIT ACTUATION TEST
MODE
The Circuit Actuation Test Mode checks for proper
operation of output circuits or devices the Powertrain
Control Module (PCM) may not internally recognize.
The PCM attempts to activate these outputs and
allow an observer to verify proper operation. Most of
the tests provide an audible or visual indication of
device operation (click of relay contacts, fuel spray,
etc.). Except for intermittent conditions, if a device
functions properly during testing, assume the device,
its associated wiring, and driver circuit work cor-
rectly. Connect the DRB scan tool to the data link
connector and access the Actuators screen.
