Ignition Switch: Service and Repair

IGNITION SWITCH

REMOVAL

1. Disconnect negative battery cable from battery.

2. Place shifter in PARK position.

3. Remove tilt-wheel lever (pulls out).

Lower Shroud Screws:

4. Remove 2 lower shroud screws (size T25).

Shroud Pivot Point:

5. Upper and lower shrouds are snapped together at sides. Pivot points for lower and upper shrouds is at rear of shrouds. Lower shroud is hooked to pins on upper shroud. Tilt lower shroud down for removal.

Upper Shroud Screws:

6. Remove 2 upper shroud screws (size T5) and remove upper shroud from steering column.

7. If removing key lock cylinder only, proceed to next step. If removing ignition switch, proceed to IGNITION SWITCH REMOVAL.

8. IGNITION SWITCH REMOVAL: Key lock cylinder removal is not necessary for ignition switch removal.

Installing Lock Cylinder to Column:

Removing/Installing Alarm Switch:

a. Remove alarm switch. Alarm switch is located at right/upper side of steering column. Press on retaining clip with a small screw-driver while rotating switch 1/4 turn for removal.

b. Remove knee blocker below steering column.

c. Note position of wiring harnesses and all tie wraps between ignition switch and 4-way connector at lower part of steering column. When installing ignition switch/wire harness assembly, the harnesses must be correctly routed with tie wraps in correct position to prevent damage to harness.

d. If equipped with overdrive (OD) transmission, unclip OD wire harness at ignition switch.

e. Cut necessary tie wraps.

Ignition Switch Mounting Screws:

f. Remove 2 ignition switch mounting screws (size T4) and separate switch at steering column.

Separating 48-Way Connectors at Lower Part of Column:

g. Separate steering column 48-way electrical connectors by removing one fastener (bolt). The 48-way connector is located near lower part of steering column. This 48-way connector contains 48 different pin-outs including 3 different connectors: a 17-way for the multi-function switch; a 13-way for the multi-function switch; and an 18-way for the ignition switch.

Steering Column 48-Way Connector (Male Connector to Column Shown):

h. Separate 17-way multi-function switch connector from 18-way ignition switch connector.

i. Separate 13-way multi-function switch connector from 18-way ignition switch connector.

j. Separate multi-function switch wire harnesses from ignition switch wiring harness.

k. Remove wiring harness and ignition switch as an assembly from steering column.

INSTALLATION

1.

a. Position switch and wire harness assembly to steering column.

b. Install switch screws and tighten to 1.4 N-m (12 in. lbs.) torque.

c. Carefully route ignition switch wire harness down to bottom of steering column.

d. If equipped with overdrive (OD) transmission, clip OD wire harness to ignition switch.

e. Route alarm switch wire harness around ignition switch.

f. Attach alarm switch to steering column by rotating and snapping into position).

g. Attach 13-way multi-function switch connector to ignition switch 18-way connector.

h. Attach 17-way multi-function switch connector to ignition switch 18-way connector.

i. Attach both 48-way electrical connectors together (1 bolt). Tighten bolt to 7 N-m (62 in. lbs.) torque.

j. Install new tie wraps in their previously noted positions.

k. If equipped with a tilt steering wheel, operate tilt mechanism while observing wiring harnesses for binding. Correct binding if necessary.

l. Operate shift lever while observing wiring harnesses for binding. Correct binding if necessary.

2. A 2-5/8" long plastic spacer is attached to inside of upper shroud. Before positioning shroud to column, verify spacer is tightened to upper shroud.

3. Position upper shroud to steering column.

4. Install 2 upper shroud screws.

5. Position rubber shields for shift lever and multi-function switch into upper shroud.

6. Position lower shroud hooks into pins on upper shroud.

7. Snap lower shroud to upper shroud.

8. Install 2 lower shroud screws.

9. Install tilt-wheel lever (snaps in).

10. Shifter should lock in PARK position when key is in LOCK position. Shifter should unlock when key rotated to ON position.

11 Check for proper operation of ignition switch in ACCESSORY, LOCK, OFF, ON, RUN, and START positions.

12. Steering wheel should lock when key is in LOCK position. Rotate steering wheel to verify.

Steering wheel should unlock when key is rotated to ON position.

13. Connect negative battery cable to battery.
