Air Bag Systems: Service Precautions

WARNING:
- To avoid rendering the SRS inoperative,which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation,all maintenance must be performed by an authorized NISSAN dealer.
- Improper maintenance,including incorrect removal and installation of the SRS,can lead to personal injury caused by unintentional activation of the system.
- Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual SRS wiring harnesses are covered with yellow insulation either just before the harness connectors or for the complete harness,for easy identification.

Precautions for SRS "Air Bag" 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 deploy.
Therefore,do not work on any air bag system connectors or wires until at least ten minutes have passed.
- Diagnosis sensor unit must always be installed with arrow mark "~" pointing towards the front of the vehicle for proper operation.Also check diagnosis sensor unit 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 modules carefully.Always place them with the pad side facing upward.
- Do not use old bolts after removing any SRS parts; replace with new bolts.Conduct self-diagnosis to check entire SRS for proper function.
- After air bag inflates,the front instrument panel assembly should be replaced.
