The Supplemental Restraint System (SRS) is designed to work in conjunction with the standard three-point safety belts to reduce injury in a head-on collision.
Depending on your vehicle, the SRS may be comprised of some or all of the following components:
The sensors in the car are designed to detect a severe frontal impact. When at least one of the primary crash sensors and the center cowl safing rear air bag sensor close at the same time, electric current flows to the inflator and ignites the chemicals.
The chemicals burn rapidly in the metal container. This burning produces nitrogen gas and small amounts of dust, both the gas and dust are cooled and filtered during the air bag(s) inflation.
The air bag(s) split the trim covers open while inflating. The air bag(s) then rapidly unfold and inflate in front of the driver or passenger.
After the air bag(s) have inflated, the gas escapes through holes in the bag(s) and the they will deflate.
Several precautions must be observed when handling the inflator module to avoid accidental deployment and possible personal injury:
DISARMING THE SYSTEMS
- Disconnect both battery cables, negative cable first.
- Wait at least 1 minute. This allows time for the backup power supply to deplete its stored energy.
- Remove the driver's side air bag module and then the passenger side if required.
- Use caution when carrying live air bags. Always place the air bag with the cover up.
- If the battery needs to be reconnected while one or both of the air bags are removed from the system, install Air Bag Simulator 105-00010 or equivalent, to the driver's side and/or passenger side air bag harness connectors as required. Before removing either air bag simulator, disconnect both battery cables and wait at least 1 minute before continuing.
ARMING THE SYSTEM
- Once service is completed and the air bag modules are back in place, connect the negative battery cable and prove out the air bag system by turning the ignition key to the RUN position and visually monitoring the air bag indicator lamp in the instrument cluster. The indicator lamp should illuminate for approximately 6 seconds and then turn OFF. if the indicator lamp does not illuminate, stays ON, or flashes at any time, a fault has been detected by the air bag diagnostic monitor requiring immediate attention.
