T SRS AIR BAG SYSTEM GENERALPROCEDURES Before Servicing 1. Deactivate the audio antitheft system, if installed. (Refer to page T-120.) 2. Disconnect the negative battery cable. 3. Remove the lower panel. 4. Disconnect the orange and blue clock spring connec- tors. 5. Remove the glove compartment. 6. Disconnect the orange and blue passenger-side air bag module connectors. I , 46UOTXd21 TROUBLESHOOTING Troubleshootinn Procedure The air bag diagnostic module has a self-diagnosis function that flashes or illuminates the AIR BAG sys- tem warning light to indicate trouble in the air bag system. The trouble can be determined by the warning light illumination or flashing pattern. If the light does not illuminate but the system still has trouble, a warn- ing buzzer will sound 5 cycles of 5 times each. . .

SRS AIR BAG SYSTEM T AIR BAG MODULE DISPOSAL PROCEDURE Before scrapping a vehicle with an undeployed air bag module, deploy the air bag. Never dispose of a live air bag module. If the deployment tool SST is not available, consult the nearest Mazda representa- i/ tive for assistance. 46UOTX-908 Air Bag Deployment 1. Move the vehicle to an open space, away from strong winds, and open all of the vehicle's doors. 2. Deactivate the audio antitheft system, if installed. (Refer to page T-120.) 3. Disconnect the negative battery cable. 4. Follow the appropriate procedure for the driver-side or passenger-side air bag module. Driver-side air bag module (1 ) Make sure the air bag module is firmly mounted to the steering wheel. (2) Remove the lower panel. (3) Disconnect the orange and blue clock spring con- nectors. (4) Inspect the SST. (Refer to page T-217.) (5) Connect the SST to the clock spring connector as shown in the figure. Passenger-side air bag module (1) Remove the glove compartment.
