Air Bag Systems: Service Precautions

Precautions for SRS "Air Bag" and "Seat Belt Pre-tensioner" Service

^ Do not use a circuit tester to check SRS circuits.

^ Before servicing the SRS, turn ignition switch "OFF", disconnect both battery cables and wait at least 10 minutes.For approximately 10 minutes after the cables are removed, it is still possible for the air bag to inflate. Therefore, do not work on any air bag system connectors or wires until at least 10 minutes have passed.

^ SRS sensors must always be installed with their arrow marks facing the front of the vehicle for proper operation. Also check sensors for cracks, deformities or rust before installation and replace as required.

^ The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to turn steering wheel or column after removal of steering gear.

^ Handle air bag module carefully. Always place it with the pad side facing upward.

^ Do not use old bolts after removing any SRS parts; replace with new ones. Conduct self-diagnosis to check entire SRS for proper function.

^ If front of vehicle is damaged in a collision, always check the crash zone sensor and the wiring harness.

^ After air bag inflates, the front instrument panel assembly should be replaced.

^ When laying aside a single pre-tensioner (belt assembly), make sure cylinder tip does not point towards a person. Always place pre-tensioner in a box if possible. (If pre-tensioner should go off accidentally, rubber cap will jump out of cylinder tip, blowing out high temperature gas.)
