Air Bag Deactivation Switch: Description and Operation
The inflatable restraint IP module switch is a manual 2-position key switch located in the instrument panel, to the right of the steering wheel. This switch
gives the vehicle operator the ability to enable or disable inflatable restraint IP module (Passenger Front Air Bag) deployment should the vehicle be
involved in a severe frontal collision. The vehicle operator may choose to disable the inflatable restraint IP module if there is no occupant in the front
seat, or if there is a child in a rear-facing child seat in the front seat.
The manual key-switch operates in 2 positions. When the key is vertical, the switch is in the OFF position and the inflatable restraint IP module is in the
suppressed (disabled) state. In the suppressed state, the inflatable restraint IP module will not deploy in the event of a severe frontal collision. When the
key is horizontal, the switch is in the ON position and the inflatable restraint IP module is in the nonsuppressed (enabled) state. In the nonsuppressed
state, the inflatable restraint IP module will deploy in the event of a severe frontal collision. The key-switch assembly also includes a backlit switch cover
which illuminates when the headlights are on.
The IP module switch is directly interfaced to the inflatable restraint Sensing and Diagnostic Module (SDM). The SDM senses the state of the IP module
switch. When the switch is in the ON position, the SDM enables possible deployment of the inflatable restraint IP module. When the switch is in the OFF
position, the SDM disables or inhibits possible deployment of the inflatable restraint IP module.
