NOTE:
Before installing the steering wheel, the front
wheels should be aligned straight ahead.
Be sure to install the harness wires so that they
are not pinched or interfering with other parts.
After reassembly, confirm that the wheels are
still turned straight ahead and that the steering
wheel spoke angle is correct (road test). If minor
spoke angle adjustment is necessary, do so only
by adjusting the tie-rods, not by removing and
repositioning the steering wheel.
Set the cancel sleeve so that the projections are

Installation
Airbag installation
CAUTION:
• Before installing the steering wheel, align the front
wheels straight ahead.
• Be sure to install the harness wires so that they are
not pinched or interfering with other vehicle parts.
• Do not replace the original steering wheel with any
other design, since it will make it impossible to prop-
erly install the airbag. (Only use 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, do so only by adjustment of the tie-rods, not by
removing and repositioning the steering wheel.
Confirm that the airbag assembly is
securely attached to the steering wheel; otherwise,
severe personal injury could result during airbag
deployment.
1. Before installing the steering wheel, center the cable
reel. Do this by first rotating the cable reel clockwise
until it stops. Then rotate it counterclockwise
approximately two turns.
The arrow mark on the cable reel label should point
straight up.

Description
The cruise control system uses mechanically and electri-
cally operated devices to maintain vehicle speed at a
setting selected by the driver.
The cruise control unit receives command signals from
the cruise control main switch and the cruise control
set/resume/cancel switch. It receives information about
operating conditions from the brake switch, ECM, vehi-
cle speed sensor (VSS), or the A/T gear position switch.
The cruise control unit sends operational signals to the
devices that regulate the throttle position. The throttle
position maintains the selected vehicle speed.
Essentially, the control unit compares the actual speed
of the vehicle to the selected speed. Then, the control
unit uses the result of that comparison to open or close
the throttle.
The brake switch releases the system's control of the
throttle at the instant the driver depresses the brake
pedal. The switch sends an electronic signal to the con-
trol unit when the brake pedal is depressed; the control
unit responds by allowing the throttle to close. The A/T
gear position switch sends a disengage signal input to
the control unit that also allows the throttle to close.
Operation:
The cruise control system will set and automatically
maintain any speed above 25 mph (40 km/h). To set a
speed, make sure that the main switch is in the "ON"
position. After reaching the desired speed, press the set
switch. The cruise control unit will receive a set signal
and, in turn, will actuate the cruise control actuator. If
you depress the set switch is when the cruise control
system is on, the "cruise light", an indicator in the
gauge assembly, will come on. You can cancel the
cruise control system by depressing the cancel switch or
by pushing the main switch to "OFF". This removes
power to the control unit and erases the set speed from
memory. If the system is disengaged temporarily by the
brake switch or the A/T gear position switch and vehicle
speed is still above 25 mph (40 km/h), press the resume
switch. With the resume switch depressed and the set
memory retained, the vehicle will automatically return
to the previous set speed.
For gradual acceleration without depressing the acceler-
ator pedal, push the resume switch down and hold it
there until the desired speed is reached. This will send
an acceleration signal to the control unit. When the
switch is released, the system will be reprogrammed for
the new speed. To slow the vehicle down, depress the
set switch. This will send a deceleration signal to the
control unit, causing the vehicle to coast. When you
reach the desired speed, release the set switch. This will
reprogram the system for the new speed.ProCarManuals.com

Cruise Control
Description (cont'd)
The electrically operated actuator controls the throttle position in the same way as a vacuum operated actuator. The mag-
netic clutch is part of the safety system and controls acceleration and deceleration.

DECELERATION
ACCELERATION
ACTUATOR CABLE
Acceleration
Due to the rotation of the motor output shaft, power is transmitted to the magnetic clutch by the transmission gear and
the worm wheel. The magnetic clutch is rotated and magnetized. It attracts the clutch plate and power is transmitted to the
output link by the gear directly connected to the clutch plate and the output gear. The output link rotates clockwise, then
the actuator cable opens the throttle, and the car accelerates.
Deceleration
The motor output shaft rotates in reverse direction of acceleration, then, in the same way, the power is transmitted to the
output link. The output link rotates counterclockwise, then the actuator cable closes the throttle, and the car decelerates.

Troubleshooting
NOTE:
The numbers in the table show the troubleshooting sequence.
Before troubleshooting,
— Check the No. 1 (10 A) and the No. 4 (15 A)*1 or (20 A)*2 fuses in the under-dash fuse/relay box, and the No. 30 (20 A)
fuses in the under-hood fuse/relay box.
— Check that the horns sound.
— Check the tachometer to see if it works properly.ProCarManuals.com
