PASSENGER AIRBAG
DESCRIPTION
The rearward facing surface of the injection
molded, thermoplastic passenger airbag door is the
most visible part of the passenger airbag (Fig. 34).
The passenger airbag door is located above the glove
box opening on the instrument panel in front of the
front seat passenger seating position. The upper and
outboard edges of the airbag door are secured with
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 an air conditioning panel outlet
and housing. The panel outlet housing features four
snap features that secure it to the back of the airbag
door and a mounting tab that is also secured with
one screw to the upper glove box opening reinforce-
ment.
Located behind the passenger airbag door within
the instrument panel is the passenger airbag unit
(Fig. 35). 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 passengerairbag 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
multistage, Next Generation-type that complies with
revised federal airbag standards to deploy with less
force than those used in some prior models. The pas-
senger airbag unit consists of a stamped and welded
metal housing, the airbag cushion, the airbag infla-
tor, 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 air-
bag inflator and the folded airbag cushion. An
approximately 80 centimeter (31.5 inch) wide by 90
centimeter (35.5 inch) high rectangular fabric cush-
ion is used.
The airbag inflator is a non-azide, pyrotechnic-type
unit that is secured to and sealed within the airbag
housing. A short four-wire pigtail harness with a
keyed, yellow connector insulator connects the two
inflator initiators to the vehicle electrical system
through a dedicated take out and connector of the
instrument panel wire harness.
The passenger airbag includes the airbag door and
the panel outlet housing. This unit cannot be
repaired, and must be replaced if deployed, faulty, or
in any way damaged.

DODGE RAM 1500 1998 2.G Workshop Manual OPERATION
The multistage passenger airbag is deployed by
electrical signals generated by the Airbag Control
Module (ACM) through the passenger airbag squib 1
and squib 2 circuits to the two initiators

OPERATION
The multistage passenger airbag is deployed by
electrical signals generated by the Airbag Control
Module (ACM) through the passenger airbag squib 1
and squib 2 circuits to the two initiators in the air-
bag inflator. By using two initiators, the airbag can
be deployed at multiple levels of force. The force level
is controlled by the ACM to suit the monitored
impact conditions by providing one of four delay
intervals between the electrical signals provided to
the two initiators. The longer the delay between
these signals, the less forcefully the airbag will
deploy.
When the ACM sends the proper electrical signals to
each initiator, the electrical energy generates enough
heat to initiate a small pyrotechnic charge which, in
turn ignites chemical pellets within the inflator. Once
ignited, these chemical pellets burn rapidly and pro-
duce a large quantity of inert gas. The inflator is
sealed to the airbag cushion and a diffuser in the infla-
tor directs all of the inert gas into the airbag 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 an air-
bag deployment, the airbag cushion quickly deflates by
venting the inert gas through vent holes within the
fabric used to construct the back (instrument panel
side) of the airbag cushion.
Typically, both initiators are used during an airbag
deployment event. However, it is possible for only one
initiator to be used during a deployment due to an
airbag system fault; therefore, it is necessary to
always confirm that both initiators have been used in
order to avoid the improper disposal of potentially
live pyrotechnic materials. (Refer to 8 - ELECTRI-
CAL/RESTRAINTS - STANDARD PROCEDURE -
SERVICE AFTER A SUPPLEMENTAL RESTRAINT
DEPLOYMENT).
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 deployment
before removing the airbag from the vehicle. (Refer to

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. 39). 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 housing
connects 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
on/off switch or Off indicator circuits, and will illumi-
nate the airbag indicator in the instrument cluster if
a fault is detected. For proper diagnosis of the pas-
senger airbag on/off switch or the ACM, a DRBIIIt
scan tool is required. Refer to the appropriate diag-
nostic information.
