Impact Airbag Control Modules (SIACM). An airbag
indicator in the ElectroMechanical Instrument Clus-
ter (EMIC) illuminates for about six seconds as a
bulb test each time the ignition switch is turned to
the On or Start positions. Following the bulb test,
the airbag indicator is turned on or off by the ACM
to indicate the status of the supplemental restraint
system. If the airbag indicator comes on at any time
other than during the bulb test, it indicates that
there is a problem in the supplemental restraint sys-
tem electrical circuits. Such a problem may cause air-
bags not to deploy when required, or to deploy when
not required.
Deployment of the supplemental restraints
depends upon the angle and severity of an impact.
Deployment is not based upon vehicle speed; rather,
deployment is based upon the rate of deceleration as
measured by the forces of gravity (G force) upon the
impact sensors. When an impact is severe enough,
the microprocessor in the ACM or the SIACM signals
the inflator of the appropriate airbag units to deploy
their airbag cushions. The outboard front seat belt
tensioners are provided with a deployment signal by
the ACM in conjunction with the driver and passen-
ger airbags. During a frontal vehicle impact, the
knee blockers work in concert with properly fastened
and adjusted seat belts to restrain both the driver
and the front seat passenger in the proper position
for an airbag deployment. The knee blockers also
absorb and distribute the crash energy from the
driver and the front seat passenger to the structure
of the instrument panel. The seat belt tensioner
removes the slack from the outboard front seat belts
to provide further assurance that the driver and
front seat passenger are properly positioned and
restrained for an airbag deployment.
Typically, the vehicle occupants recall more about
the events preceding and following a collision than
they do of an airbag deployment itself. This is
because the airbag deployment and deflation occur so
rapidly. In a typical 48 kilometer-per-hour (30 mile-
per-hour) barrier impact, from the moment of impact
until the airbags are fully inflated takes about 40
milliseconds. Within one to two seconds from the
moment of impact, the airbags are almost entirely
deflated. The times cited for these events are approx-
imations, which apply only to a barrier impact at the
given speed. Actual times will vary somewhat,
depending upon the vehicle speed, impact angle,
severity of the impact, and the type of collision.When the ACM monitors a problem in any of the
dual front airbag system circuits or components,
including the seat belt tensioners, it stores a fault
code or Diagnostic Trouble Code (DTC) in its memory
circuit and sends an electronic message to the EMIC
to turn on the airbag indicator. When the SIACM
monitors a problem in any of the side curtain airbag
system circuits or component, it stores a fault code or
DTC in its memory circuit and sends an electronic
message to the ACM, and the ACM sends an elec-
tronic message to the EMIC to turn on the airbag
indicator. Proper testing of the supplemental
restraint system components, the Programmable
Communications Interface (PCI) data bus, the elec-
tronic message inputs to and outputs from the EMIC,
the SIACM, or the ACM, as well as the retrieval or
erasure of a DTC from the ACM, SIACM, or EMIC
requires the use of a DRBIIItscan tool. Refer to the
appropriate diagnostic information.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of all of the factory-installed passive restraints.

seven integral snap features to the instrument panel
base trim, while two screws secure the integral
inboard mounting flange to the base trim, and four
screws secure the lower mounting flange to the upper
glove box opening reinforcement integral to the
instrument panel structural support. The passenger
airbag door includes two air conditioning panel out-
lets and their housings. Each of the panel outlet
housings feature four snap features that secure them
to the back of the airbag door and two mounting tabs
that are also secured with one screw each to the
upper glove box opening reinforcement.
Located behind the passenger airbag door within
the instrument panel is the passenger airbag unit
(Fig. 31). The passenger airbag housing fits into a
molded receptacle on the back of the airbag door,
where six stamped hook formations on the upper and
lower edges of the airbag housing are engaged in six
small window openings on the upper and lower
flanges of the receptacle to secure the airbag door to
the airbag housing. The inboard airbag door fasten-
ers and mounting flange are concealed beneath the
instrument panel center bezel, while the lower fas-
teners and mounting flange are concealed beneath
the instrument panel lower surround. The passenger
airbag unit is secured by four screws through four
brackets (two front and two rear) that are integral to
the base of the airbag housing to the instrument
panel structural support.
The passenger airbag unit used in this model is a
Next Generation-type that complies with revised fed-
eral airbag standards to deploy with less force thanthose used in some prior models. The passenger air-
bag unit consists of a stamped and welded metal
housing, the airbag cushion, the airbag inflator, and
a stamped metal airbag and inflator retainer plate
that is secured to the airbag housing with six studs
and nuts. The airbag housing contains the airbag
inflator and the folded airbag cushion. An approxi-
mately 80 centimeter (31.5 inch) wide by 90 centime-
ter (35.5 inch) high rectangular fabric cushion is
used. The airbag inflator is a non-azide, pyrotechnic-
type unit that is secured to and sealed within the air-
bag housing. The inflator initiator is connected to the
vehicle electrical system through a dedicated take
out and connector of the instrument panel wire har-
ness.
The passenger airbag includes the airbag door and
the two panel outlet housings. This unit cannot be
repaired, and must be replaced if deployed, faulty, or
in any way damaged.
OPERATION
The passenger airbag is deployed by an electrical
signal generated by the Airbag Control Module
(ACM) through the passenger airbag squib circuits to
the initiator in the airbag inflator. The hybrid-type
inflator assembly includes a small canister of highly
compressed inert gas. When the ACM sends the
proper electrical signal to the airbag inflator, the ini-
tiator converts the electrical energy into chemical
energy. This chemical energy produces the pressure
necessary to rupture a burst disk in the inert gas
canister.
The inflator is sealed to the airbag cushion so that
all of the released inert gas is directed into the air-
bag cushion, causing the cushion to inflate. As the
cushion inflates, the passenger airbag door will split
at predetermined tear seam lines concealed on the
inside surface of the door, then the door will pivot up
over the top of the instrument panel and out of the
way. Following a passenger airbag deployment, the
airbag cushion quickly deflates by venting the inert
gas through vent holes within the fabric used to con-
struct the back (instrument panel side) of the airbag
cushion.
REMOVAL
The following procedure is for replacement of a
faulty or damaged passenger airbag. If the airbag is
faulty or damaged, but not deployed, review the rec-
ommended procedures for handling non-deployed
supplemental restraints. (Refer to 8 - ELECTRICAL/
RESTRAINTS - STANDARD PROCEDURE - HAN-
DLING NON-DEPLOYED SUPPLEMENTAL
RESTRAINTS). If the passenger airbag has been
deployed, review the recommended procedures for
service after a supplemental restraint deploymentFig. 31 Passenger Airbag Unit

PASSENGER AIRBAG ON/OFF
SWITCH
DESCRIPTION
The passenger airbag on/off switch is standard
equipment on all standard cab versions of this model
when they are equipped with the dual front airbag
system (Fig. 35). This switch is a two-position, resis-
tor multiplexed switch with a single integral red
Light-Emitting Diode (LED), and a non-coded key
cylinder-type actuator. The switch is located in the
lower right corner of instrument panel center bezel,
near the center of instrument panel to make the Off
indicator visible to all front seat occupants. When the
switch is in its installed position, the only compo-
nents visible through the dedicated opening of the
cluster bezel are the switch face plate and nomencla-
ture, and the key cylinder actuator. The9Off9position
of the switch is illuminated when this switch position
is selected, while the ªOnº position of the switch is
designated by text imprinted upon the face plate of
the switch, but is not illuminated. The remainder of
the switch is concealed behind the switch face plate
and the instrument panel center bezel.
The passenger airbag on/off switch housing is con-
structed of molded plastic and has three integral
mounting tabs. These mounting tabs are used to
secure the switch to the back of the molded plastic
switch face plate with three small screws. The
molded plastic face plate also has three integral
mounting tabs that are used to secure the switch and
face plate unit to the instrument panel center bezel
with three additional screws. A molded plastic con-
nector receptacle on the back of the switch housingconnects the switch to the vehicle electrical system
through a dedicated take out and connector of the
instrument panel wire harness. The molded plastic
harness connector insulator is keyed and latched to
ensure proper and secure switch electrical connec-
tions. The passenger airbag on/off switch cannot be
adjusted or repaired and, if faulty or damaged, the
switch must be replaced.
OPERATION
The passenger airbag on/off switch allows the cus-
tomer to turn the passenger airbag function On or
Off to accommodate certain uses of the right front
seating position where airbag protection may not be
desired. See the owner's manual in the vehicle glove
box for specific recommendations on when to enable
or disable the passenger airbag. The Off indicator of
the switch will be illuminated whenever the switch is
turned to the Off position and the ignition switch is
in the On position.
The ignition key is the only key or object that
should ever be inserted into the key cylinder actuator
of the switch. The on/off switch requires only a par-
tial key insertion to fully depress a spring-loaded
locking plunger. The spring-loaded locking plunger
prevents the user from leaving the key in the switch.
The key will be automatically ejected when force is
not applied. To actuate the passenger airbag on/off
switch, insert the ignition key into the switch key
actuator far enough to fully depress the plunger, then
rotate the actuator to the desired switch position.
When the switch key actuator is rotated to its clock-
wise stop (the key actuator slot will be aligned with
the Off indicator), the Off indicator is illuminated
and the passenger airbag is disabled. When the
switch is rotated to its counterclockwise stop (the key
actuator slot will be in a vertical position), the Off
indicator will be extinguished and the passenger air-
bag is enabled.
The passenger airbag on/off switch connects one of
two internal resistors in series between the passen-
ger airbag mux switch sense and passenger airbag
mux switch return circuits of the Airbag Control
Module (ACM). The ACM continually monitors the
resistance in these circuits to determine the switch
position that has been selected. When the switch is
in the Off position, the ACM provides a ground input
to the switch through the passenger airbag indicator
driver circuit, which energizes the Light-Emitting
Diode (LED) that illuminates the Off indicator of the
switch.
The ACM will also illuminate the Off indicator of
the switch for about seven seconds each time the
ignition switch is turned to the On position as a bulb
test. The ACM will store a Diagnostic Trouble Code
(DTC) for any fault it detects in the passenger airbag

²Washer Pump/Motor- The electric washer
pump/motor unit is located in a dedicated hole on the
rearward facing surface of the washer reservoir in
the engine compartment.
²Washer Reservoir- On all models except those
with an optional V-10 or diesel engine, the washer
reservoir is secured by integral mounting tabs and a
snap feature to slots in the right side of the cooling
module shroud in the engine compartment. On mod-
els with an optional V-10 or diesel engine, the washer
reservoir is secured by screws to the back of the
upright left vertical member of the radiator support
in the engine compartment. The washer reservoir
filler neck is accessed from the engine compartment.
²Wiper Arm- The two wiper arms are secured
with integral latches to the serrated ends of the two
wiper pivot shafts, which extend through the cowl
plenum cover/grille panel located near the base of the
windshield.
²Wiper Blade- The two wiper blades are
secured to the two wiper arms with an integral latch,
and are parked on the glass near the bottom of the
windshield when the wiper system is not in opera-
tion.
²Wiper High/Low Relay- The wiper high/low
relay is an International Standards Organization
(ISO) micro relay located in the Integrated Power
Module (IPM) in the engine compartment near the
battery.
²Wiper Module- The wiper pivot shafts are the
only visible components of the wiper module. The
remainder of the module is concealed within the cowl
plenum area beneath the cowl plenum cover/grille
panel. The wiper module includes the wiper module
bracket, four rubber-isolated wiper module mounts,
the wiper motor, the wiper motor crank arm, the two
wiper drive links, and the two wiper pivots.
²Wiper On/Off Relay- The wiper on/off relay is
an International Standards Organization (ISO) micro
relay located in the Integrated Power Module (IPM)
in the engine compartment near the battery.
Hard wired circuitry connects the wiper and
washer system components to the electrical system of
the vehicle. These hard wired circuits are integral to
several wire harnesses, which are routed throughout
the vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the wiper and washer
system components through the use of a combination
of soldered splices, splice block connectors, and many
different types of wire harness terminal connectors
and insulators. Refer to the appropriate wiring infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
OPERATING MODES
The components of the wiper and washer system
are designed to work in concert to provide the follow-
ing operating modes:
²Continuous Wipe Mode- The control knob on
the control stalk of the multi-function switch has two
continuous wipe positions, Low and High. When
selected, these switch positions will cause the two-
speed wiper motor to operate in a continuous low or
high speed cycle.
²Intermittent Wipe Mode- The control knob on
the control stalk of the multi-function switch has five
minor detent intermittent wipe positions. When
selected, these switch positions will cause the wiper
system to operate with one of five delay intervals
between complete wipe cycles. The intermittent wipe
delay intervals are speed sensitive and will be dou-
bled when the vehicle speed is about sixteen kilome-
ters-per-hour (ten miles-per-hour) or less.
²Pulse Wipe Mode- When the control knob on
the control stalk of the multi-function switch is
depressed to the momentary Wash position for less
than about one-half second, the wiper system will
operate the wipers for one complete low speed cycle,
then will park the wiper blades near the base of the
windshield.
²Washer Mode- When the control knob on the
control stalk of the multi-function switch is
depressed to the momentary Wash position for more
than about one-half second with the wiper system
turned Off, the washer pump/motor and the wipers
will operate for as long as the washer switch is held
closed up to about thirty seconds, then the wipe-af-
ter-wash mode is invoked when the control knob is
released. When the Wash position is selected with
the wiper system operating in a continuous wipe
mode, washer fluid will be dispensed onto the wind-
shield glass through the washer nozzles for as long
as the washer switch is held closed up to about thirty
seconds. When the Wash position is selected with the
wiper system operating in an intermittent wipe
mode, washer fluid is still dispensed until the control
knob is released; however, the 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 interval. If the control
knob is held in the depressed Wash position for more
than about thirty seconds, washer system operation
will be suspended until the control knob is released
for about two seconds then cycled back to the Wash
position.

WASHER RESERVOIR
DESCRIPTION
Except on models equipped with an optional V-10
or diesel engine, the molded plastic washer fluid res-
ervoir is mounted on the right rearward facing sur-
face of the cooling module radiator shroud in the
engine compartment (Fig. 14). On models with the
V-10 or diesel engine, the molded plastic washer fluid
reservoir is mounted on the rearward facing surface
of the left vertical member of the radiator support in
the engine compartment. The reservoir is a molded
unit constructed of a translucent plastic that allows
the washer fluid level to be inspected without remov-
ing the washer reservoir cap. The most visible com-
ponent of the washer reservoir is the filler cap unit,
which is secured to and hinges on a hook feature
that is integral to the filler neck near the top of the
reservoir. The bright yellow plastic filler cap snaps
over the filler neck opening and seals the reservoiropening with an integral rubber gasket. The filler
cap is labeled with an International Control and Dis-
play Symbol icon for ªWindshield Washerº and the
text ªWasher Fluid Onlyº that are molded into it and
highlighted in black against the yellow plastic cap for
visibility.
There are dedicated holes near the bottom of the
rearward facing side of the reservoir provided for the
mounting of the washer pump/motor unit and the
washer fluid level switch. A snap post receptacle
molded into the reservoir allows for mounting of the
washer pump without the use of fasteners. The res-
ervoir also features an integral hose routing trough
on its rearward facing side. Except on models with a
V-10 or diesel engine, the washer reservoir is secured
to the cooling module radiator shroud with three
integral tabs, two at the bottom and one at the top.
The two bottom tabs are inserted into two slots near
the bottom of the shroud, while the upper tab slides
into an integral channel-like slot near the top of the
shroud. A molded lock feature on the forward facing
surface of the reservoir engages a molded depression
on the rearward facing surface of the radiator shroud
when the reservoir is fully seated on the shroud,
locking the unit securely in place. On models with a
V-10 or diesel engine, the washer reservoir is secured
with two screws through integral mounting tabs to
the left vertical member of the radiator support. On
many models, a molded plastic coolant recovery con-
tainer or a coolant pressure container must be
detached from the top of the cooling module and
moved aside to access the washer fluid reservoir for
service. This may be accomplished without opening
or draining the engine cooling system.
OPERATION
The washer fluid reservoir provides a secure,
on-vehicle storage location for a large reserve of
washer fluid for operation of the washer system. The
washer reservoir filler neck provides a clearly
marked and readily accessible point from which to
add washer fluid to the reservoir. The washer/pump
motor unit is located in a sump area near the bottom
of the reservoir to be certain that washer fluid will
be available to the pump as the fluid level in the res-
ervoir becomes depleted. The washer pump/motor
unit is mounted in the lowest position in the sump.
The washer fluid level switch is mounted just above
the sump area of the reservoir so that there will be
adequate warning to the vehicle operator that the
washer fluid level is low, well before the washer sys-
tem will no longer operate.
