6. Pop the wire harness assembly (4) out of the wire harness strap (5).
7. Remove the 3 wire harness straps (3) from the wire harness assembly.
8. Remove the wire harness strap (2) from the upper tilt head assembly (1).




9. Remove the coil assembly retaining clip (1).
10. Remove the coil assembly (2).

INSTALLATION PROCEDURE

NOTE: Verify that all fasteners are securely seated before applying needed torque. Failure to do so may result in component damage or malfunctioning of the steering column.




1. Install the wave washer (1).
2. To install the SIR coil assembly, align the block tooth on the race and upper shaft assembly to the 12 O'clock position.

IMPORTANT:
^ Verify that the coil assembly is centered.
^ The coil assembly becomes un-centered under the following conditions:
- The steering column is separated from the steering gear and allowed to rotate.
- The centering spring is pushed down, letting the hub rotate while the coil is removed from the steering column. In the event this occurs. Refer to In flatable Restraint Coil Centering - Off Vehicle (Column Shift And Floor Shift) in Steering Wheel and Column.




3. Install the pre-centered coil assembly to the steering column. Remove the centering tab (1) and discard.




4. Install the coil assembly (2) using the following components for alignment:
^ The horn tower (1) on the canceling cam assembly inner ring.
^ The projections on the outer ring.

IMPORTANT: Gently pull on the lower coil assembly wire in order to remove any wire kinks inside the column assembly. Verify that there are NO kinks or in the SIR coil assembly wire. If a kink or bend is present, interference may occur with the shaft lock mechanism. Turning the steering wheel may cut or damage the wire.




5. Install the coil assembly retaining ring. Verify that the ring (1) is firmly seated in the groove on the upper shaft assembly (2).




6. Pop the wire harness assembly (4) into the wire strap (5).
7. Install the wire harness strap (2) into the upper tilt head assembly (1).
8. Install 3 wire harness straps (3) to the wire harness assembly.
9. Install the multi-function switch lever.
10. Install the upper and lower steering column trim covers.
11. Install the tilt lever (if equipped).
12. Install the steering wheel assembly.
13. Enable the SIR system.
