FOREWORD
The information contained in this service manual has been prepared for the professional automotive tech-
nician involved in daily repair operations. This manual does not cover theory of operation, which is addressed
in service training material. Information describing the operation and use of standard and optional equipment
is included in the Owner's Manual provided with the vehicle.
Information in this manual is divided into groups. These groups contain general information, diagnosis,
testing, adjustments, removal, installation, disassembly, and assembly procedures for the components.
The Component and System Index of this manual identifies the correct group for the component or system
to be serviced. In addition, a Service Manual Comment form is included at the rear of this manual. Use the
form to provide Chrysler Corporation with your comments and suggestions.
To assist in locating a group title page, use the Group Tab Locator on the following page. The solid bar
after the group title is aligned to a solid tab on the first page of each group. The first page of the group has
a contents section that lists major topics within the group.
Tightening torques are provided as a specific value throughout this manual. This value represents the
midpoint of the acceptable engineering torque range for a given fastener application. These torque values are
intended for use in service assembly and installation procedures using the correct OEM fasteners. When re-
placing fasteners, always use the same type (part number) fastener as removed.
Chrysler Corporation reserves the right to change testing procedures, specifications, diagnosis, repair
methods, or vehicle wiring at any time without prior notice or incurring obligation.
NOTE: The acronyms, terminology and nomenclature used to identify emissions related components in
this manual may have changed from prior publications. These new terms are in compliance with S.A.E.
recommended practice J1930. This terminology standard (J1930) is required to comply with the 1993
California Air Research Board (CARB) requirements.

VEHICLE DESIGNATIONS
The Vehicle Code chart lists description and code
for Ram Truck and Sport Utility vehicles. The codes
are used to identify vehicle types in charts, captions
and in service procedures. The vehicle codes are dif-
ferent than the Vehicle Identification Number (VIN)
or the wheelbase/model code.
VEHICLE SAFETY CERTIFICATION LABEL
A certification label is attached to the left side
B-pillar. The label certifies that the vehicle conforms
to Federal Motor Vehicle Safety Standards (FMVSS).
The label also lists the:
• Month and year of vehicle manufacture
• Gross Vehicle Weight Rating (GVWR). The gross
front and rear axle weight ratings (GAWR's) are
based on a minimum rim size and maximum cold tire
inflation pressure
Vehicle Identification Number (VIN)
Type of vehicle
Type of rear wheels (single or dual)
Bar code
Month, Day and Hour (MDH) of final assembly
VEHICLE IDENTIFICATION NUMBER (VIN) PLATE
The Vehicle Identification Number (VIN) plate is
attached to the top left side of the instrument panel.
The VIN contains 17 characters that provide data
concerning the vehicle. Refer to the decoding chart to
determine the identification of a vehicle.

The Vehicle Identification Number is also im-
printed on the:
• Body Code Plate
• Equipment Identification Plate
• Vehicle Safety Certification Label
• And on a frame rail.
VEHICLE CODE PLATE
A metal vehicle code plate (Fig. 2) is attached to
top, right side of cowl below cowl grille. There can be
a maximum of seven rows of vehicle information im-
printed on the plate. The information should be read
from left to right, starting with line 1 at the bottom
of the plate up to line 7 (as applicable) at the top of
the code plate.
Refer to the decoding chart to decode lines 1
through 3.
Lines 4 through 7 on the plate are imprinted in se-
quence according to the following descriptions:
• 3-character sales code
• 3-digit numerical code
• 6-digit SEC code
If there is not enough space left in the row for all
of the 6-digit SEC code:
• The unused space will remain blank
• The code will be listed in the next row.
The last nine positions of row 7 will contain a
2-digit code and a 6-digit serial number.
The last code on a vehicle code plate will be fol-
lowed by the imprinted word END. When two plates
are required, the last available spaces on the first
plate will be imprinted with the letters CTD (for con-
tinued).
When a second vehicle code plate is necessary, the
first four spaces on each row will not be used because
of the plate overlap.
To retrieve information from a vehicle code plate:
• Illuminate the plate with a shop light
• View the plate via the cowl grille slots
• Record the needed coded information.
