Clockspring Assembly / Spiral Cable: Service and Repair

CLOCKSPRING

WARNING: TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, AIRBAG, OCCUPANT CLASSIFICATION SYSTEM, SEAT BELT TENSIONER, IMPACT SENSOR, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT.

CAUTION: A service replacement clockspring is shipped with the clockspring pre-centered and with a molded plastic locking pin installed. This locking pin should not be removed until the clockspring has been installed on the steering column. If the locking pin is removed before the clockspring is installed on a steering column, the clockspring centering procedure must be performed.

NOTE: Before starting this procedure, be certain to turn the steering wheel until the front wheels are in the straight-ahead position.

REMOVAL




1. Place the front wheels in the straight ahead position.
2. Disconnect and isolate the battery negative cable.
3. Remove the driver airbag from the steering wheel.
4. Disconnect the steering wheel wire harness connectors from the upper clockspring connector receptacles.

CAUTION: Be certain that the screws that secure the steering wheel puller to the steering wheel are fully engaged in the steering wheel armature without passing through the steering wheel and damaging the clockspring.

5. Remove the steering wheel from the steering column
6. If the vehicle is equipped with the optional tilt steering column, move the column to the fully lowered position and leave the tilt release lever in the released (down) position.
7. From below the steering column, remove the two screws (4) that secure the lower shroud (5) to the upper shroud (2).
8. Using hand pressure, push gently inward on both sides of the upper shroud above the parting line between the upper and lower shrouds to release the snap features that secure the two shroud halves to each other.
9. Remove both the upper and lower shrouds from the steering column.
10. Disconnect the two instrument panel wire harness connectors for the clockspring from the two connector receptacles located below the steering column on the back of the clockspring (3) case.
11. If the vehicle is equipped with the optional Electronic Stability Program (ESP) there will be an applied pigtail wire connector located below the steering column on the back of the clockspring case for the Steering Angle Sensor (SAS) that is internal to the clockspring. Disconnect the instrument panel wire harness connector for the SAS from the pigtail connector.
12. Using a small thin-bladed screwdriver, release the two integral plastic latches that secure the back of the clockspring case to the steering column lock housing (1).
13. Remove the clockspring from the steering column lock housing. The clockspring cannot be repaired. It must be replaced if faulty or damaged, or if the driver airbag has been deployed.
14. If the removed clockspring is to be reused, be certain to secure the clockspring rotor to the clockspring case to maintain clockspring centering until it is reinstalled on the steering column. If clockspring centering is not maintained, the clockspring must be centered again before it is reinstalled.

INSTALLATION




1. Carefully slide the centered clockspring (3) down over the steering column upper shaft until the two integral plastic latches on the back of the clockspring case are fully engaged through their openings in the steering column lock housing (1).
2. If the vehicle is equipped with the optional Electronic Stability Program (ESP) there will be an applied pigtail wire connector located below the steering column on the back of the clockspring case for the Steering Angle Sensor (SAS) that is internal to the clockspring. Reconnect the instrument panel wire harness connector for the SAS to the pigtail connector.
3. Reconnect the two instrument panel wire harness connectors for the clockspring to the two connector receptacles located below the steering column on the back of the clockspring case.
4. Position the upper (2) and lower (5) shrouds onto the steering column.
5. Align the snap features on the lower shroud with the receptacles in the upper shroud and apply hand pressure to snap them together.
6. From below the steering column, install and tighten the two screws (4) that secure the lower shroud to the upper shroud. Tighten the screws to 2 N.m (18 in. lbs.).
7. If the vehicle is equipped with the optional tilt steering column, move the column back to the fully raised position and move the tilt release lever back to the locked (up) position.
8. If a new clockspring has been installed, remove the plastic locking pin that secures the clockspring rotor to the clockspring case to maintain clockspring centering.
9. Reinstall the steering wheel onto the steering column.

NOTE: Be certain that the steering wheel mounting screw is tightened to the proper torque specification to ensure proper clockspring operation.
10. Reconnect the steering wheel wire harness connector to the upper clockspring connector receptacle.
11. Reinstall the driver airbag onto the steering wheel.
12. Reconnect the battery negative cable.
