AUDIO Inspection c Fuse ness. ml JHFDB If the antenna fails to raise or lower, make the following checks: 1. Check the antenna fuse (10A). 2. Replace fuse after checking and repairing wiring har- Power antenna 1. Check for continuity between the terminals of the power antenna relay. If there is no continuity, replace the relay. Terminal I M: Continuity 2. If the antenna does not function even though there is continuity, the problem may be either in the wiring har- ness or in the audio component assembly. 3. Apply battery positive voltage to the terminals and check the operation. I I A 1 B 1 DOWN I Function of antenna UP Battery Pos. D Neg. A Gartner Banana

T AUDIO / SNAP-RING OUN TlNG NUT BROKEN Antenna Mast Removal / Installation 1. Using snap-ring pliers, remove the mounting nut. 2. With the ignition switch at ACC or ON, turn the radio switch on, and pull out the antenna mast. Check the end of the plastic rack for damage. If the rack end is kinked or broken, replace the motor. 3. With the ignition switch at ACC or ON and the radio on, feed the rack of the new mast into the motor with toothed side facing toward the front of the vehicle. Turn the radio off. While the motor is retracting the rack, feed the mast into the motor. 4. Reinstall the mounting nut. 5. With the ignition switch at ACC or ON, turn the radio on and off a few times and check to see that the antenna op- erates smoothly. Gartner Banana

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. . . Flowchart I START Troubleshoot warning light circuit Does AIR BAG system warning light illuminate for 4-8 secs and I I Yes t Refer to service code table and troubleshoot system Press horn switch while turning steering wheel.

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. (2) Disconnect the orange and blue passenger-side air bag module connector. Gartner Banana
