API QUALITY CLASSIFICATION
This symbol (Fig. 2) on the front of an oil container
means that the oil has been certified by the Ameri-
can Petroleum Institute (API) to meet all the lubri-
cation requirements specified by DaimlerChrysler
Corporation.
GEAR LUBRICANTS
SAE ratings also apply to multigrade gear lubri-
cants. In addition, API classification defines the
lubricants usage. Such as API GL-5 and SAE 75W-
90.
LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 3) on the label. At the bottom NLGI
symbol is the usage and quality identification letters.
Wheel bearing lubricant is identified by the letter
ªGº. Chassis lubricant is identified by the latter ªLº.
The letter following the usage letter indicates the
quality of the lubricant. The following symbols indi-
cate the highest quality.
SPECIALIZED LUBRICANTS AND OILS
Some maintenance or repair procedures may
require the use of specialized lubricants or oils. Con-
sult the appropriate sections in this manual for the
correct application of these lubricants.
DESCRIPTION - AXLE
A multi-purpose, hypoid gear lubricant which con-
forms to MIL-L-2105C and API GL 5 quality specifi-
cations should be used. Mopar Hypoid Gear
Lubricants conforms to these specifications.
FRONT AXLE
²Lubricant for 186FIA (Model 30) axle is SAE
75W-140 SYNTHETIC.
REAR AXLE
²Lubricant for 198RBI (Model 35) axle is SAE
75W-140 SYNTHETIC.
²Lubricant for 8 1/4 axle is a thermally stable
SAE 75W-90. For trailer tow or heavy duty applica-
tions the lubricant should be replaced with SAE
75W-140 SYNTHETIC.
NOTE: Trac-lokTequipped axles require a friction
modifier be added to the lubricant.
CAUTION: If axle is submerged in water, lubricant
must be replaced immediately to avoid possible
premature axle failure.
DESCRIPTION - MANUAL TRANSMISSION
Mopartmanual transmission fluid is the lubricant
recommended for the NV1500 and the NV3550 trans-
missions.
DESCRIPTION - AUTOMATIC TRANSMISSION
FLUID
NOTE: Refer to the maintenance schedules in this
group for the recommended maintenance (fluid/filter
change) intervals for this transmission.
NOTE: Refer to Service Procedures in this group for
fluid level checking procedures.
MopartATF +4, type 9602, Automatic Transmis-
sion Fluid is the recommended fluid for
DaimlerChrysler automatic transmissions.
Dexron II fluid IS NOT recommended. Clutch
chatter can result from the use of improper
fluid.
MopartATF +4, type 9602, Automatic Transmis-
sion Fluid when new is red in color. The ATF is dyed
red so it can be identified from other fluids used in
the vehicle such as engine oil or antifreeze. The red
color is not permanent and is not an indicator of fluid
condition. As the vehicle is driven, the ATF will begin
to look darker in color and may eventually become
brown.This is normal.ATF+4 also has a unique

COOLING (Continued)

OPERATION
OPERATION - COOLING SYSTEM
The cooling system regulates engine operating tem-
perature. It allows the engine to reach normal oper-
ating temperature as quickly as possible. It also
maintains normal operating temperature and pre-
vents overheating.
The cooling system also provides a means of heat-
ing the passenger compartment and cooling the auto-
matic transmission fluid (if equipped). The cooling
system is pressurized and uses a centrifugal water
pump to circulate coolant throughout the system.
OPERATION - HOSE CLAMPS
The spring type hose clamp applies constant ten-
sion on a hose connection. To remove a spring type
hose clamp, only use constant tension clamp pliers
designed to compress the hose clamp.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - ON-BOARD
DIAGNOSTICS (OBD)
COOLING SYSTEM RELATED DIAGNOSTICS
The powertrain control module (PCM) has been
programmed to monitor certain cooling system com-
ponents:
²If the engine has remained cool for too long a
period, such as with a stuck open thermostat, a Diag-
nostic Trouble Code (DTC) can be set.
²If an open or shorted condition has developed in
the relay circuit controlling the electric radiator fan,
a Diagnostic Trouble Code (DTC) can be set.
If the problem is sensed in a monitored circuit
often enough to indicated an actual problem, a DTC
is stored. The DTC will be stored in the PCM mem-
ory for eventual display to the service technician.
(Refer to 25 - EMISSIONS CONTROL - DESCRIP-
TION).
ACCESSING DIAGNOSTIC TROUBLE CODES
To read DTC's and to obtain cooling system data,
(Refer to 25 - EMISSIONS CONTROL - DESCRIP-
TION).
ERASING TROUBLE CODES
After the problem has been repaired, use the DRB
scan tool to erase a DTC. Refer to the appropriate
Powertrain Diagnostic Procedures service informa-
tion for operation of the DRB scan tool.
DIAGNOSIS AND TESTING - PRELIMINARY
CHECKS
ENGINE COOLING SYSTEM OVERHEATING
Establish what driving conditions caused the com-
plaint. Abnormal loads on the cooling system such as
the following may be the cause:
²PROLONGED IDLE
²VERY HIGH AMBIENT TEMPERATURE
²SLIGHT TAIL WIND AT IDLE
²SLOW TRAFFIC
²TRAFFIC JAMS
²HIGH SPEED
²STEEP GRADES
Driving techniques that avoid overheating are:
²Idle with A/C off when temperature gauge is at
end of normal range.
(1) TRAILER TOWING:
Consult Trailer Towing section of owners manual.
Do not exceed limits.
(2) RECENT SERVICE OR ACCIDENT REPAIR:
Determine if any recent service has been per-
formed on vehicle that may effect cooling system.
This may be:
²Engine adjustments (incorrect timing)
²Slipping engine accessory drive belt(s)
²Brakes (possibly dragging)
²Changed parts. Incorrect water pump, or pump
rotating in wrong direction due to belt not correctly
routed
²Reconditioned radiator or cooling system refill-
ing (possibly under filled or air trapped in system).
NOTE: If investigation reveals none of the previous
items as a cause for an engine overheating com-
plaint, refer to following Cooling System Diagnosis
charts.
These charts are to be used as a quick-reference
only. Refer to the group text for information.

LEAKS
ULTRAVIOLET LIGHT METHOD
A leak detection additive is available through the
parts department that can be added to cooling sys-
tem. The additive is highly visible under ultraviolet
light (black light). Pour one ounce of additive into
cooling system. Place heater control unit in HEAT
position. Start and operate engine until radiator
upper hose is warm to touch. Aim the commercially
available black light tool at components to be
checked. If leaks are present, black light will cause
additive to glow a bright green color.

controls the ground for the heated seat switch indi-
cator lamps (LED's).
When a heated seat switch (Driver or Passenger) is
depressed a signal is received by the heated seat
module, the module energizes the proper indicator
LED (Low or High) in the switch by grounding the
indicator lamp circuit to indicate that the heated seat
system is operating. At the same time, the heated
seat module energizes the selected heated seat sensor
circuit and the sensor provides the module with an
input indicating the surface temperature of the
selected seat cushion.
The Low heat set point is about 36É C (96.8É F),
and the High heat set point is about 42É C (107.6É F).
If the seat cushion surface temperature input is
below the temperature set point for the selected tem-
perature setting, the heated seat module energizes
an N-channel Field Effect Transistor (N-FET) within
the module which energizes the heated seat elements
in the selected seat cushion and back. When the sen-
sor input to the module indicates the correct temper-
ature set point has been achieved, the module
de-energizes the N-FET which de-energizes the
heated seat elements. The heated seat module will
continue to cycle the N-FET as needed to maintain
the selected temperature set point.
If the heated seat module detects a heated seat
sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the
vehicle operator or the repair technician of this con-
dition by flashing the High and/or Low indicator
lamps in the affected heated seat switch. Refer to
Diagnosis and Testing Heated Seat Systemin
Heated Systems for flashing LED diagnosis and test-
ing procedures. Refer toDiagnosis and Testing
Heated Seat Modulein this section for heated seat
module diagnosis and testing procedures. Also refer
to the Body Diagnostic Manual for additional diagno-
sis and testing procedures.
DIAGNOSIS AND TESTING - HEATED SEAT
MODULE

indicator lamps on a heated seat switch flash, refer
toHeated Seat System Diagnosis and Testingin
Heated Systems for flashing LED failure identifica-
tion. Refer toWiring Diagramsin for complete
heated seat system wiring diagrams.

ness connector (Fig. 15), do not disconnect. Check
cavity #3 for battery voltage when the right heated
seat switch is turned ªONº, voltage should be
present, If OK go to Step 3 If NOT OK, test the right
heated seat switch (Refer to 8 - ELECTRICAL/
HEATED SEATS/PASSENGER HEATED SEAT
SWITCH - DIAGNOSIS AND TESTING). If the
switch tests OK, check for continuity between the
switch and control module on the MUX circuit, If OK
replace the heated seat control module. If NOT OK,
repair the open or shorted MUX circuit as required.

HEATED SEAT MODULE (Continued)

OPERATION
There are three positions that can be selected with
each of the heated seat switches: Off, Low, and High.
When the front of the switch rocker is fully
depressed, the High position is selected and the high
position LED indicator illuminates. When the rear of
the switch rocker is fully depressed, the Low position
is selected and the low position LED indicator illumi-
nates. When the switch rocker is depressed a second
time in either direction, Off is selected and both LED
indicators are extinguished.
Both switches provide separate resistor multi-
plexed hard wire inputs to the Heated Seat Module
to indicate the selected switch position. The heated
seat module monitors the switch inputs and responds
to the heated seat switch status messages by control-
ling the output to the seat heater elements of the
selected seat. The Low heat position set point is
about 36É C (97É F), and the High heat position set
point is about 41É C (105É F).
DIAGNOSIS AND TESTING - HEATED SEAT
SWITCH
If a heated seat fails to heat and one or both of the
indicator lamps on a heated seat switch flash, refer
toHeated Seat System Diagnosis and Testingin
this section for flashing LED failure identification.
Refer toWiring Diagramsfor complete heated seat
system wiring diagrams.
(1) If the problem being diagnosed involves a
heated seat switch indicator lamp that remains illu-
minated after the heated seat has been turned Off,refer toDiagnosis and Testing the Heated Seat
Modulein the Electronic Control Modules section for
heated seat module diagnosis and testing procedures.
If not, go to Step 2
(2) Remove the heated seat switch (Refer to 8 -
ELECTRICAL/HEATED SEATS/DRIVER HEATED
SEAT SWITCH - REMOVAL). Check for continuity
between the ground circuit cavity #5 of the heated
seat switch connector and a good ground. There
should be continuity. If OK, go to Step 3. If not OK,
repair the open ground circuit as required.
(3) Turn the ignition switch to the ON position.
Check for battery voltage at the fused ignition switch
output circuit cavity #1 of the heated seat switch con-
nector. If OK, go to Step 4. If not OK, repair the open
fused ignition switch output circuit as required.
(4) Check the continuity between pin #1 and pin
#3 of the heated seat switch (Fig. 2). If the readings
do not correspond to those in the Heated Seat Switch
Continuity table below, replace the heated seat
switch. If OK, and the heated seat system is still not
operating properly refer toDiagnosis and Testing
the Heated Seat Module.

²Intermittent Wipe Mode- The control knob on
the right (wiper) control stalk of the multi-function
switch has five minor detent intermittent wipe posi-
tions. When selected, these switch positions will
cause the front wiper system to operate with one of
five delay intervals between complete wipe cycles.
²Mist Wipe Mode- The right (wiper) control
stalk of the multi-function switch has a momentary
Mist position. When selected, this switch position
will operate the front wipers in a low speed continu-
ous cycle for as long as the switch is held closed,
then will complete the current wipe cycle and park
the front wiper blades near the base of the wind-
shield when the switch is released.
²Washer Mode- When the momentary front
wash position of the right (wiper) control stalk of the
multi-function switch is selected with the front wiper
system operating in a continuous wipe mode, washer
fluid will be dispensed onto the windshield glass
through the washer nozzles for as long as the washer
switch is held closed. When the front washer switch
is actuated with the front wiper system operating in
an intermittent wipe mode, washer fluid is still dis-
pensed until the switch is released; however, the
front wipers will operate in a low speed continuous
cycle from the time the washer switch is closed until
several wipe cycles after the switch is released,
before returning to the selected intermittent wipe
mode.
²Wipe-After-Wash Mode- When the momentary
front wash position of the right (wiper) control stalk
of the multi-function switch is selected with the front
wiper system turned Off, the internal circuitry of the
BCM provides a wipe-after-wash feature. When
selected, this feature will operate the washer pump/
motor and the front wipers for as long as the front
washer switch is held closed, then provide several
additional wipe cycles after the switch is released
before parking the front wiper blades near the base
of the windshield.
OPERATION
The front wiper and washer system is designed to
provide the vehicle operator with a convenient, safe,
and reliable means of maintaining visibility through
the windshield glass. The various components of this
system are designed to convert electrical energy pro-
duced by the vehicle electrical system into the
mechanical action of the wiper blades to wipe the
outside surface of the glass, as well as into the
hydraulic action of the washer system to apply
washer fluid stored in an on-board reservoir to the
area of the glass to be wiped. When combined, these
components provide the means to effectively main-
tain clear visibility for the vehicle operator by remov-
ing excess accumulations of rain, snow, bugs, mud, orother minor debris from the outside windshield glass
surface that might be encountered while driving the
vehicle under numerous types of inclement operating
conditions.
The vehicle operator initiates all front wiper and
washer system functions with the right (wiper) con-
trol stalk of the multi-function switch that extends
from the right side of the steering column, just below
the steering wheel. Rotating the control knob on the
end of the control stalk, selects the Off, Delay, Low,
or High front wiper system operating modes. In the
Delay mode, the control knob also allows the vehicle
operator to select from one of five intermittent wipe
Delay intervals. Pulling the right control stalk down-
wards actuates the momentary front wiper system
Mist mode switch, while pulling the right control
stalk towards the steering wheel actuates the
momentary front washer system switch. The multi-
function switch provides hard wired resistor multi-
plexed inputs to the Body Control Module (BCM) for
all of the front wiper system functions, as well as a
separate hard wired sense input to the BCM for the
front washer system function.
The front wiper and washer system will only oper-
ate when the ignition switch is in the Accessory or
On positions. Battery current is directed from a B(+)
fuse in the Power Distribution Center (PDC) to the
wiper and washer system circuit breaker in the Junc-
tion Block (JB) through a fused ignition switch out-
put (run-acc) circuit. The automatic resetting circuit
breaker then provides battery current through a
fused ignition switch output (run-acc) circuit to the
wiper high/low relay, the wiper on/off relay, and the
park switch within the front wiper motor. A separate
fuse in the JB provides battery current through
another fused ignition switch output (run-acc) circuit
to the multi-function switch. The multi-function
switch circuitry uses this battery feed and a ground
circuit input to directly control the operation and
direction of the reversible electric washer pump/mo-
tor unit. The BCM uses low side drivers to control
front wiper system operation by energizing or de-en-
ergizing the wiper high/low and wiper on/off relays.
The hard wired circuits and components of the
front wiper and washer system may be diagnosed
and tested using conventional diagnostic tools and
procedures. However, conventional diagnostic meth-
ods may not prove conclusive in the diagnosis of the
Body Control Module (BCM), or the inputs to or out-
puts from the BCM that control the front wiper and
washer system operating modes. The most reliable,
efficient, and accurate means to diagnose the BCM,
or the BCM inputs and outputs related to the various
front wiper and washer system operating modes
requires the use of a DRBIIItscan tool. Refer to the
appropriate diagnostic information.
8R - 4 FRONT WIPERS/WASHERSKJ
FRONT WIPERS/WASHERS (Continued)

OPERATION
The front check valve provides more than one func-
tion in this application. It serves as a wye connector
fitting between the cowl grille panel and washer noz-
zle sections of the front washer supply hose. It also
prevents washer fluid from draining out of the front
washer supply hoses back to the washer reservoir.
This drain-back would result in a lengthy delay when
the front washer switch is actuated until washer
fluid was dispensed through the front washer noz-
zles, because the washer pump would have to refill
the front washer plumbing from the reservoir to the
nozzles. Finally, the front check valve prevents
washer fluid from siphoning through the front
washer nozzles after the front washer system is
turned Off.
Within the check valve body, a small check valve is
held in place against a seat by a small coiled spring
to restrict flow through the unit until the valve is
unseated by a predetermined inlet fluid pressure.
When the washer pump pressurizes and pumps
washer fluid from the reservoir through the front
washer plumbing, the fluid pressure overrides the
spring pressure applied to the check valve and
unseats the valve, allowing washer fluid to flow
toward the front washer nozzles. When the washer
pump stops operating, spring pressure seats the
check valve and fluid flow in either direction within
the front washer plumbing is prevented.
