so that gap between throttle cam and lever is 10
1mm
(0.040
0.04in).
(Must be attached while throttle cam is being pulled by wire
cable.)

B: REMOVAL AND INSTALLATION
1. CRUISE CONTROL MAIN SWITCH
1) Remove screws which secure meter visor.
2) Remove meter visor from instrument panel while dis-
connecting connectors.
3) Remove cruise control main switch from meter visor.
B6M0357A
2. CRUISE CONTROL COMMAND SWITCH
1) Remove screw which secures horn pad to the base of
steering wheel.
2) Remove horn pad from steering wheel while discon-
necting connector.
3) Disconnect connector of cruise control command
switch.
4) Remove screws which secure cruise control command
switch to steering wheel, and then remove command
switch.
WARNING:
Refer to 5-5 when removing or installing the module
from the airbag equipped model.
B6M0156
3. ACTUATOR
1) Loosen nut which secures cruise control cable end to
throttle cam, and then remove cable from engine throttle
cam.
2) Remove clip bands from cruise control cable.
CAUTION:

Be careful not to apply excessive load to the wire
cable when adjusting and/or installing; otherwise, the
actuator may be deformed or damaged.

Do not bend cable sharply with a radius less than
100 mm (3.94 in); otherwise, cable may bend
permanently, resulting in poor performance.

When installing cable, be careful not to sharply bend
or pinch the inner cable; otherwise, the cable may
break.

C: DRIVING TESTS
Conduct road tests by selecting a smooth, flat road or use
free rollers as road test simulation.
1. MAIN SWITCH
1) Turn ignition switch ON.
2) Check that indicator light comes on when main switch
is pressed (ON).
3) Check that indicator light goes out when main switch is
pressed again (OFF).
4) Turn ignition switch OFF with main switch ON (which is
indicated by illumination.).
5) Turn ignition switch ON again to ensure that indicator
light remains OFF.
2. COMMAND SWITCH
1) Check that command switch is properly set in“SET/
COAST”,“RESUME/ACCEL”or“CANCEL”mode.
2) Also check that command switch returns to the original
position when released.
3. CONSTANT SPEED TEST
1) Turn main switch ON.
2) Drive vehicle at speed greater than 40 km/h (25 MPH).
3) Press command switch to set in“SET/COAST”mode.
4) Ensure that vehicle is maintained at the speed set when
command switch was pressed.
4. ACCELERATION TEST
1) Set vehicle speed at speed greater than 40 km/h (25
MPH).

2) Ensure that vehicle continues to accelerate while hold-
ing command switch in RESUME/ACCEL mode, and that
vehicle maintains that optional speed when command
switch is released.
5. DECELERATION TEST
1) Set vehicle speed at optional speed greater than 40
km/h (25 MPH).
2) Ensure that vehicle continues to decelerate while hold-
ing command switch in SET/COAST mode, and that it
maintains that optional speed when command switch is
released.
NOTE:
When vehicle speed reaches the lower speed limit of 30
km/h (19 MPH) during deceleration, cruise control will be
released.
