1995-97 STEERING Mazda Motors Corp. - Steering Columns
DESCRIPTION & OPERATION
Steering columns are designed to be collapsible upon impact. The steering column consists of solid steering
shaft with a lower joint assembly. Some models are equipped with tilt steering. Turn signal, headlight, ignition
and windshield washer/wiper switches are mounted on column. Switches can be serviced by removing steering
wheel and column covers. All models are equipped with air bag restraint system consisting of an driver air bag
module, passenger air bag module (except 1995 MPV and 1995 Protege) and clockspring connector assembly
located in the steering column.
SYSTEM OPERATION CHECK
1. Turn ignition switch to ON or START position. AIR BAG warning light in instrument cluster should
illuminate for about 4-8 seconds, and then turn off. This indicates air bag system is functioning properly.
2. If any of the following conditions exists, air bag system is malfunctioning and requires servicing.
AIR BAG warning light does not illuminate as specified.
AIR BAG warning light remains illuminated for more than 8 seconds.
AIR BAG warning light illuminates while driving.
3. If air bag system components are replaced for any reason, air bag system must be checked for proper
function after repair. Repeat step 1). If AIR BAG warning light does not illuminate as specified, air bag
system is malfunctioning and servicing is required. See AIR BAG RESTRAINT SYSTEM article.
SERVICE PRECAUTIONS
Observe the following precautions when servicing air bag system.
Disable air bag system before servicing any air bag system or steering column component. See AIR BAG
DISABLING & ACTIVATING .
After disabling air bag system, wait at least one minute before servicing. Air bag system voltage is
maintained for approximately one minute after system is disabled. Failure to wait one minute before
servicing system may cause accidental air bag deployment and possible personal injury.
Obtain radio code number from customer and deactivate radio anti-theft function (if equipped) before
disconnecting battery.
Because of the critical operation requirements of system, DO NOT service any air bag system
component. Repairs are made by replacement only.
DO NOT use an ohmmeter to check resistance of air bag module, as it may cause air bag deployment.
When carrying a live (undeployed) air bag module, ensure trim cover is pointed away from your body. WARNING:To avoid injury from accidental air bag deployment, read and carefully
follow all WARNINGS and SERVICE PRECAUTIONS
.

This minimizes chance of injury in the event of accidental air bag deployment.
When placing a live air bag module on any surface, always face trim cover upward to reduce motion of
module if it is accidentally deployed.
If an open circuit is present, replace entire wiring harness. DO NOT attempt to repair wire(s).
Air bag system clockspring MUST be aligned in neutral position, since its rotation ability is limited. DO
NOT turn steering wheel or column after removal of steering gear.
A double-lock mechanism is used on clockspring connectors. DO NOT use excessive force when
disconnecting connectors, as damage to connector may occur.
