15. Three cross recess screws (12).
16. Turn signal switch assembly (15). Let switch hang freely, if removal is not needed. To remove, turn signal switch (15).
a). Turn signal switch connector from vehicle wire harness and connector body bracket assembly (56).
b). Hexagon nut (57).
c). Connector body bracket (56).
d). Wiring protector (43).
e). Turn signal switch (15) connector through column.
NOTICE: Coil assembly (3) will become uncentered if:
1). Steering column is separated from steering gear and is allowed to rotate, or
2). Centering spring is pushed down, letting hub rotate while coil (3) is removed from steering column.
17. Inflatable restraint coil assembly (3) with wire harness from column assembly.
a). Wiring protector (43).
b). Ensure that connector shroud (5) has been removed. Attach a length of mechanics wire to terminal connector to aid in reassembly.
c). Gently pull wire through column.
NOTICE: When removing buzzer switch assembly (18) buzzer switch retaining clip (42) may become disconnected. Ensure that retaining clip (42) does not drop into column assembly. Failure to do so may result in component damage or malfunctioning of steering column.
18. Buzzer switch assembly (18) with buzzer switch retaining clip (42). Clip (42) from buzzer switch (18).
19. Lock retaining screw (19).
20. Steering column lock cylinder set (22).
Install or Connect
NOTICE: Ensure all fasteners are securely seated before applying needed torque. Failure to do so may result in component damage or malfunctioning of steering column.
1. Steering column lock cylinder set (22).
2. Lock retaining screw (19). Tighten screw (19) to 4.5 N-m (40 lb.in.)
3. Buzzer switch retaining clip (42) to buzzer switch (18). Buzzer switch (18) with retaining clip (42) to steering column housing assembly (20). Ensure that clip (42) does not drop into column assembly.
4. Coil assembly (3) wire harness through column. Let coil hang freely.
5. Turn signal switch assembly (15) wire harness through steering column.
a). Wire protector (43).
b). Connector body bracket (56) with hexagon nut (57). Tighten nut (57) to 4.0 N-m (35 lb.in.).
c). Turn signal switch (15) connector to vehicle wire harness and connector body bracket (56).
6. Turn signal switch assembly (15) with screws (12). Tighten screws (12) to 3.4 N-m (30 lb.in.).
7. Switch actuator arm (14) and screw (13). Tighten screw (13) to 2.3 N-m (20 lb.in.).
8. Hazard knob assembly and multi-function lever.
9. Thrust washer (17).
10. Upper bearing spring (11).
11. Turn signal cancel cam assembly (10). Lubricate with grease, synthetic (service kit).
12. Shaft lock (9).
13. New shaft lock retaining ring (8) using J 23653-SIR to push down shaft lock (9). Ring (8) must be firmly seated in groove on shaft.
14. Shaft lock spacer (7).
NOTICE: Set steering shaft so that block tooth on upper steering shaft (46) is at the 12 o'clock position, wheels on vehicle should be straight ahead, then set ignition switch to "LOCK" position, to ensure no damage to coil assembly (3).
15. Wave washer (4).
NOTICE: Coil assembly (3) will become uncentered if:
1) Steering column is separated from steering gear and is allowed to rotate, or
2) Centering spring is pushed down, letting hub rotate while coil is removed from column.
NOTICE: If a new coil assembly (3) is being installed, assemble pre-centered coil assembly (3) to steering column. Remove centering tab and dispose.
NOTICE: SIR coil assembly wire must be kept tight with no slack while installing SIR coil assembly. Failure to do so may cause wire to be kinked near shaft lock area and cut when steering wheel is turned.
16. Ensure coil assembly (3) hub is centered.
17. Coil assembly (3).
a). Pull wires tight while positioning SIR coil to steering shaft.
b). Align opening in coil with horn tower and "locating bump" between two tabs on housing cover.
c). Seat coil assembly into steering column.
d). Connector shroud (5).
18. Coil assembly retaining ring (2). Ring (2) must be firmly seated in groove on shaft.
NOTICE: Gently pull lower coil assembly and turn signal harness to remove any wire kinks that may be inside steering column assembly. Failure to do so may cause damage to wire harness.
19. Wiring protector (43).
20. Negative (-) battery cable.
21. If all service operations are completed, enable the SIR system.
Inspect
a). Function check turn signal switch (15).
b). Position switch lever to right turn position. Turn steering wheel to left. Switch should cancel to center position.
c). Repeat above procedure for left turn position.
d). If turn signal switch does not return to center position check switch (15) forbroken or missing cancel spring, or a worn or damaged cancel cam (10).
