Replacement
WARNING: Airbag Equipped.Airbag system wiring harness is routed near the steering system.
a. All Airbag system wiring harness and connectors are colored yellow. Do not use electrical test equipment on this circuit.
b. Be careful not to damage system wiring harness when servicing.
c. Turn ignition switch "OFF" and wait 10 minutes before starting work.
d. After removal, store airbag module with pad side facing upward. Do not put any object on pad.
REMOVAL
1. Disconnect battery earth (-) terminal.
2. Remove airbag module assy. Refer to Air Bags and Seat Belts.
NOTE: Turn ignition switch "OFF" and wait 10 minutes before starting work. After removal, store airbag module with pad side facing upward. Do not put any object on pad.
a. Remove cap (LH).
b. Remove cap (RH).
c. Disconnect airbag system connector at harness spool.
d. Set front tires in straight ahead direction.
e. Remove both steering wheel covers and remove bolts securing airbag module assy using TORX bit T30.
f. Turn over airbag module assy and disconnect airbag system connector. Refer to Air Bags and Seat Belts.
g. Disconnect horn and cruise control connectors.
3. Lift vehicle and remove lower and upper bolts from universal joint assy, and then remove universal joint in the upward direction. Scribe alignment marks on universal joint assy so that it can be reassembled at the original serration.
4. Disconnect connectors for ignition switch, steering ECU, and combination switch wiring harness under instrument panel.
5. Remove two nuts and a bolt under instrument panel securing steering shaft.
6. Pull out steering shaft assy from hole on toe board. Be sure to remove universal joint before removing steering shaft assy installing bolts when removing steering shaft assy or when lowering it for servicing of other parts.
INSTALLATION
1. Insert end of steering column assy into toe-board dust seal.
2. Tighten column assy mounting bolt and nuts under instrument panel.
3. Connect ignition and combination switch connectors under instrument panel.
4. Connect airbag system connector at harness spool. Make sure-to apply double lock.
5. Set steering wheel to neutral and install it onto steering shaft. insert roll connector guide pin into guide hole on lower end of surface of steering wheel to prevent damage. Draw out airbag system connector, horn connector and cruise control connectors from guide hole of steering wheel lower end.
6. Tighten steering wheel securing nut.
7. Install universal joint.
a. While aligning marks scribed during disassembly, push long yoke of joint assy all the way into serrated portion of column assy, setting bolt hole in cutout.
b. Then pull the short yoke all the way out of the serrated portion of the gear box assy setting the bolt hole in the cutout.
c. Insert the bolt through the short yoke, pull the joint assy and confirm that the bolt is in cutout of the gearbox assy.
d. Fasten the short yoke side with a spring washer and bolt, then fasten the long yoke side. Tightening torque: 21-26 Nm (15-20 ft. lbs.).
NOTE: Make sure that universal joint bolts are tightened through notch in shaft serration. Excessively large tightening torque of universal joint bolts may lead to heavy steering wheel operation. Standard clearance between universal joint assy and Free ring Tripod Joint (FTJ): Over 15 mm (0.59 inch)
8. Installation of airbag module.
NOTE: Do not install deployed module. Do not allow harness and connector to interfere with other parts or get caught between them.
a. Make sure that ignition switch is turned "OFF". After ignition switch is turned off, wait 10 minutes before starting work.
b. Make sure that front tires are set in straight ahead direction.
c. Make sure that roll connector is in neutral position.
d. Connect airbag connector. Make sure to apply double lock.
e. Connect horn and cruise control connectors.
f. Fasten bolts securing module using TORX bit T30.
g. Install both steering wheel lower covers. Airbag warning lamp check: Make sure that when ignition switch is turned to "ON", airbag warning lamp goes off after being "lit" for 8 seconds.
