Clockspring Assembly / Spiral Cable: Service and Repair

Prior to performing replacement procedures, disarm air bag system. Refer to, Service and Repair/ Air Bag System Disarming & Air Bag System Arming. Refer to, / Specifications/ Mechanical for torque values when installing components.
All sensors and mounting bracket bolts must be carefully torqued to assure proper operation. Never power up the air bag system when any sensor is not rigidly attached to the vehicle, since the sensor could be activated when not attached, causing air bag deployment.

SIR coil assembly will become uncentered if steering column is separated from steering gear and is allowed to rotate or centering spring is pushed down, letting hub rotate while coil assembly is removed from steering column.


1. Disconnect battery ground cable, then remove steering wheel as follows:
a. Remove inflator module.
b. Remove steering wheel nut, then disconnect horn lead assembly.
c. Mark relationship of steering wheel to steering shaft, then remove steering wheel using steering wheel puller tool No. J-1859-03, or equivalent.

2. Remove coil assembly retaining ring, then the wave washer, Fig. 10.
3. Remove shaft lock retaining ring using lock plate compressor tool No. J-23653-SIR, or equivalent, to push down shaft lock. Discard ring.
4. Remove shaft lock, then the turn signal cancel cam.
5. Remove upper bearing spring, inner race seat and inner race.
6. Position turn signal lever in right turn (up) position, then remove multi-function switch as described under appropriate chassis chapter.

Fig. 12 Turn Signal Switch Arm Removal:

7. Remove round washer head screw and signal switch arm, then the oval head cross recess screw, Fig. 12.
8. Remove hazard warning button with hazard warning spring and hazard warning switch knob.
9. Remove binding head cross recess screws, then the turn signal switch assembly, noting the following:
a. Let switch hang freely if removal is not necessary.
b. Disconnect turn signal switch connector from connector body bracket and vehicle wire harness.
c. Disconnect socket and bracket assembly connector terminal from slot "D" of turn signal switch connector.
d. Remove connector body bracket, then the wiring protector.
e. Gently pull wire harness through column.
10. Remove SIR coil assembly with wire harness from column assembly.

Fig. 15 SIR Coil Assembly Alignment:

11. Reverse procedure to install, noting the following:
a. If coil assembly becomes uncentered, refer to Fig. 13.
b. If installing new coil assembly, install pre-centered coil assembly to steering column, then remove and discard centering tab, Fig. 13.
c. SIR coil assembly wire must be kept tight with no slack while installing SIR coil assembly, Fig. 14. Failure to do so may cause wire to be kinked near shaft lock area and cut when steering wheel is turned.
d. Align opening in coil with horn tower and locating bump between two tabs on bracket and cover assembly, Fig. 15, then seat coil assembly into steering column.
e. Turn signal control assembly must be in neutral position when assembling steering wheel.
f. Do not misalign steering wheel more than 1 inch from horizontal centerline.
