Fig. 7 Right Impact Sensor

(3) Remove three screws holding sensor to radiator closure panel. Remove right sensor.

INSTALLATION

(1)Mount right sensor (arrow pointed forward) to engine side of closure panel using three screws provided with the new sensor. Tighten 10 to 13 Nzm (90-120 in. lbs.) torque.

(2)Connect sensor wiring lead from harness to connector on body of sensor.

AIR BAG SYSTEM DIAGNOSTIC MODULE (ASDM)

WARNING: THE ASDM CONTAINS ONE OF THE IMPACT SENSORS WHICH ENABLE THE SYSTEM TO DEPLOY THE AIR BAG. TO AVOID ACCIDENTAL DEPLOYMENT, NEVER CONNECT ASDM ELECTRICALLY TO THE SYSTEM UNLESS IT IS BOLTED TO VEHICLE. BEFORE BEGINNING ANY AIR BAG SYSTEM REMOVAL OR INSTALLATION PROCEDURES, REMOVE AND ISOLATE THE BATTERY NEGATIVE (-) CABLE (GROUND) FROM THE VEHICLE BATTERY. THIS IS THE ONLY SURE WAY TO DISABLE THE AIR BAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIR BAG DEPLOYMENT, AND POSSIBLE PERSONAL INJURY.

WARNING: BEFORE BEGINNING ANY AIR BAG SYSTEM REMOVAL OR INSTALLATION PROCEDURES, REMOVE AND ISOLATE THE BATTERY NEGATIVE (-)

discharge before removing undeployed module.

(4)Remove the air bag module.

(5)Remove Speed Control switch and connector if so equipped or cover.

(6)Disconnect horn terminals.

(7)Remove the steering wheel.

(8)Remove upper and lower steering column shrouds to gain access to clockspring wiring.

(9)Disconnect the 2-way connector between the clockspring and the instrument panel wiring harness on top of the fuse block.

(10)To remove, pull clockspring assembly from the steering column by lifting locating fingers as necessary. The clockspring cannot be repaired, and must be replaced if faulty.

INSTALLATION

(1)Snap clockspring onto the steering column. If the clockspring is not properly positioned, follow the clockspring centering procedure before installing steering wheel.

(2)Connect the clockspring to the instrument panel harness, ensure wiring locator clips are properly seated on wiring trough. Ensure harness locking tabs are properly engaged.

(3)Install steering column shrouds. Be sure air bag wire is inside of shrouds.

(4)Front wheels should still be in the straightahead position. Install steering wheel, ensure the flats on hub align with clockspring. Pull the horn lead through the smaller upper hole. Pull the air bag and speed control leads through the larger bottom hole. Ensure leads are not pinched under the steering wheel.

(5)Connect the horn lead wire, then the air bag lead wire to the air bag module.

(6)Install the air bag module and tighten nuts to 9 to 11 Nzm (80 to 100 in. lb.) torque.

(7)Install speed control switch and connector or

cover.

(8)Do not connect battery negative cable. Refer to Air Bag Systems Check for proper procedure.

CLOCKSPRING CENTERING PROCEDURE

If the rotating tape within the clockspring is not positioned properly with the steering wheel and the front wheels, the clockspring may fail during use. The following procedure MUST BE USED to center the clockspring if it is not known to be properly positioned, or if the front wheels were moved from the straight ahead position.

BAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIR BAG DEPLOYMENT AND POSSIBLE INJURY.

WHEN AN UNDEPLOYED AIR BAG ASSEMBLY IS TO BE REMOVED FROM THE STEERING WHEEL, DISCONNECT BATTERY GROUND CABLE AND ISOLATE. ALLOW SYSTEM CAPACITOR TO DISCHARGE FOR TWO MINUTES, THEN BEGIN AIR BAG REMOVAL.

(1)Place front wheels in the straight ahead posi-

tion.

(2)Wait two minutes for the reserve capacitor to discharge before removing undeployed module.

(3)Refer to Steering Wheel procedures for removal of air bag module and steering wheel.

(4)Depress the two plastic locking pins to disengage locking mechanism (Fig. 10).

Fig. 10 Clockspring (Auto-Locking)

(5)Keeping locking mechanism disengaged, rotate the clockspring rotor in the CLOCKWISE DIRECTION to the end of travel. Do not apply excessive torque.

(6)From the end of travel, rotate the rotor two full turns and a half in the counterclockwise direction. The horn wire should end up at the top and the squib wire at the bottom. Engage clockspring locking mechanism.

(7)Refer to Steering Wheel procedures for installation of steering wheel and air bag module.

(8) Do not connect battery negative cable. Refer to Air Bag System Check for proper procedure.

STEERING WHEEL

WARNING: BEFORE BEGINNING ANY AIR BAG SYSTEM REMOVAL OR INSTALLATION PROCEDURES, REMOVE AND ISOLATE THE BATTERY NEGATIVE (-) CABLE (GROUND) FROM THE VEHICLE BATTERY. THIS IS THE ONLY SURE WAY TO DISABLE THE AIR BAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIR BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

WHEN AN UNDEPLOYED AIR BAG ASSEMBLY IS TO BE REMOVED FROM THE STEERING WHEEL, DISCONNECT BATTERY GROUND CABLE AND ISOLATE. ALLOW SYSTEM CAPACITOR TO DISCHARGE FOR TWO MINUTES. BEGIN AIR BAG REMOVAL.

REMOVAL

(1)Make sure front wheels are straight, and steering column is locked in place.

(2)Disconnect battery negative cable and isolate.

(3)Wait two minutes for the reserve capacitor to discharge before removing undeployed module.

(4)Remove four nuts attaching air bag module from the back side of steering wheel.

(5)Lift module, and disconnect connector from rear of module.

(8)Remove steering wheel with steering wheel puller Tool C-3428B.

INSTALLATION

(1)If the clockspring is not properly positioned or if front wheels were moved, follow the clockspring centering procedure before installing steering wheel. With the front wheels in the straight ahead position. Position the steering wheel on the steering column. Making sure to fit the flats on the hub of the steering wheel with the formations on the inside of the clockspring. Pull the air bag and speed control wires through the lower, larger hole in the steering wheel and the horn wire through smaller hole at the top. Make sure not to pinch wires (Fig. 11).
