Grand Cherokee 4WD Air Bag Systems: Clockspring/Spiral Cable Location
Fig.17 Clockspring Remove/Install
9. Remove the two screws that secure the clockspring case to the multi-function switch mounting housing.
10. Remove the clockspring from the multi-function switch mounting housing. The clockspring cannot be repaired. It must be replaced if faulty or
damaged, or if the driver airbag has been deployed.
11. 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.
(Refer to ELECTRICAL/RESTRAINTS/CLOCKSPRING - STANDARD PROCEDURE - CLOCKSPRING CENTERING).
INSTALLATION
The clockspring cannot be repaired. It must be replaced if faulty or damaged, or if the driver airbag has been deployed.
If the clockspring is not properly centered in relation to the steering wheel, steering shaft and steering gear, it may be damaged. (Refer to
ELECTRICAL/RESTRAINTS/CLOCKSPRING - STANDARD PROCEDURE - CLOCKSPRING CENTERING). Service replacement clocksprings
are shipped pre-centered and with a 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.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, DRIVER AIRBAG, PASSENGER AIRBAG, FRONT IMPACT
SENSOR, SIDE IMPACT SENSOR, SIDE CURTAIN AIRBAG, 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 AND POSSIBLE PERSONAL INJURY.
NOTE: Before starting this procedure, be certain that the front wheels are still in the straight-ahead position.
1. While holding the centered clockspring rotor and case stationary in relation to each other, carefully slide the clockspring down over the steering
column upper shaft.
2. Align and seat the three pins on the lower surface of the clockspring rotor hub with the three holes in the hub of the turn signal cancel cam. It
should be noted that when the clockspring is properly centered the uppermost pin on the clockspring rotor hub is the oblong pin, and it will only fit
in the oblong hole in the hub of the turn signal cancel cam.
3. Align and seat the one pin and the two mounting ears on the clockspring case to their respective holes in the multi-function switch mounting
housing.
4. Install and tighten the two clockspring mounting screws. Tighten the screws to 2.5 Nm (22 in. lbs.).
5. Reconnect the two instrument panel wire harness connectors for the clockspring to the two connector receptacles below the steering column on the
back of the clockspring case.
6. Position the lower tilting steering column shroud onto the steering column.
7. Install and tighten the screw that secures the lower tilting steering column shroud to the multi-function switch mounting housing. Tighten the screw
to 2 Nm (17 in. lbs.).
