Air Bag Systems: Service Precautions

^ Do not use electrical test equipment on any circuit related to the SRS unless instructed. SRS wiring harnesses are covered with yellow insulation either just before the harness connectors or for the complete harness, for easy identification.
^ Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes.
For approximately 3 minutes after the cables are removed it is still possible for the air bag to deploy. Therefore, do not work on any air bag system connectors or wires until at least 3 minutes have passed.
^ Diagnosis sensor unit and crash zone sensor (4WD models) must always be installed with arrow mark "<-" pointing toward the front of the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities and rust before installation and replace if necessary.
^ 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 special bolts after removing any SRS parts; replace with new special bolts. 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 (4WD models).
