• diagnostic module.
• and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Front passenger sensing system
The front passenger sensing system will turn off the front passenger’s
frontal air bag under certain conditions. The driver’s air bag and side air
bag are not part of the front passenger sensing system. The front
passenger sensing system works with sensors that are part of the front
passenger’s seat and safety belt. The sensors are designed to detect the
presence of a properly-seated occupant and determine if the front
passenger’s frontal air bag should be enabled (may inflate) or not.
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to turn off the front passenger’s frontal air bag if:
• the front passenger seat is unoccupied,
• an infant or small child weighing less than 50 pounds (23 kg) is in the
front seat, either in a child restraint, in a booster seat, or sitting
directly on the vehicle seat,
• a front passenger takes his/her weight off the seat for a period of time
For larger children and very small adults, the passenger sensing system
may leave the air bag system enabled, or turn it OFF. The occupant’s
seating position may determine whether or not the air bag is enabled.
Even with the front passenger sensing system, children 12 and
under should be properly restrained in the back seat.
