Steering Wheel

Installation

NOTE: Before installing the steering wheel, make sure

the front wheels are straight ahead.

CAUTION:

Be sure to install the harness wires so that they are

not pinched or interfering with other car parts.

Do not replace the original steering wheel with any

other design, since it will make it impossible to proper-

ly install the airbag. (Use only genuine HONDA

replacement parts.)

After reassembly, confirm that the wheels are still

straight ahead and that steering wheel spoke angle

is correct. If minor spoke angle adjustment is neces-

sary, adjust the tie-rods only. Do not remove and

reposition the steering wheel.

Confirm that the airbag assembly is secure-

ly attached to the steering wheel; otherwise, severe per-

sonal injury could result during later airbag deployment.

1. Before installing the steering wheel, center the ca-

ble reel.

Do this by first rotating the cable reel clockwise un-

til it stops.

Then rotate it counterclockwise (approximately two

turns) until:

not align the nut by loosening.

NOTE: When connecting the steering joint, make
sure that the cable reel of SRS is centered.
15. Set the steering rack in the center of its strokes.
16. Center the cable reel as follows: Turn the steering wheel left approx. 150
degrees, to check the cable reel position with
indicator.

If the cable reel is centered, the yellow gear
tooth lines up with the alignment mark on the
cover.
Return the steering wheel right approx. 150
degrees to position the steering wheel in the
straight ahead position.
