The passenger airbag on-off switch is standard
equipment on all versions of this model (Fig. 23).
This switch is a two-position, resistor multiplexed
switch with a single integral red Light-Emitting
Diode (LED), and a non-coded key cylinder-type
actuator. The switch is located on the forward end of
the floor console (both full and mini versions) to
make the Off indicator visible to all front seat occu-
pants. When the switch is in its installed position,
the only components visible through the dedicated
opening of the console switch bezel is the key cylin-
der actuator. A small, tethered, molded plastic cap
fits into the key cylinder actuator hole when the
switch is not being used. The switch nomenclature
and a lens are integral to the console switch bezel.
When the switch Off position is selected with the
ignition switch in the On position, the LED illumi-
nates the text "Off" in amber in the console switch
bezel. The "On" position of the switch is designated
by text imprinted upon the console switch bezel, but
is not illuminated. The remainder of the switch is
concealed behind the console switch 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
console switch bezel with three small screws. The
console switch bezel has four molded plastic snap fea-
tures that are used to secure the switch and bezel
unit to the floor console. A molded plastic connector
receptacle on the back of the switch housing connects
the switch to the vehicle electrical system through a
dedicated take out of the cross body wire harness.
The harness take out is equipped with a molded plas-
tic connector insulator that 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 partial 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 pas-
senger side airbag on/off switch, insert the ignition
key into the switch key actuator far enough to fully
depress the plunger, and rotate the actuator to the
desired switch position. When the switch key actua-
tor is rotated to its clockwise 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 counter-
clockwise stop (the key actuator slot will be in a ver-
tical position), the Off indicator will be extinguished
and the passenger airbag is enabled.
The passenger airbag on/off switch is connects one
of two internal resistors in series between the pas-
senger airbag mux switch sense and passenger air-
bag 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
