Anti-Squatting Control
CONTROL START
When the accelerator pedal is pressed (returned), it changes to a
higher damping force through map control of the vehicle speed and
speed change in throttle opening (closing).
There are 2 control maps - when the accelerator pedal is pressed
and when it is returned (throttle opened and closed). Furthermore,
when the throttle position sensor output voltage stays over 4.0V for
more than 1 second at vehicle speed of 3 - 100km/h (2 - 62 mph), it
is judged that there is full throttle acceleration and the damping force
is switched to MEDIUM.
CONTROL HOLD
After changing from a high damping force, there is first a 1 second
hold in that condition and then the suspension reverts to the normal
damping force (SOFT).
When full throttle acceleration is judged, the suspension reverts to
the normal damping force (SOFT) in one second after the control
conditions are not satisfied.
Pitching/Bouncing Control
CONTROL START
When the ECS control unit judges that there is serious
pitching and bouncing of the vehicle (washboard road
driving) via the output of the G-
CONTROL HOLD
When the ECS control unit judges that there is no more
pitching and bouncing of the vehicle via the output of the
Bad Road Response Control
When the ECS control unit judges that there is fine
pitching and bouncing of the vehicle (bad road such as
gravel road, etc.) via the output of the G-sensor, the
suspension is changed to MEDIUM for improved riding
Warning Display Function
When a breakdown is detected, the TOUR and SPORT
ECS indicator light in the meter blinks at 0.5 sec.
Fail-safe and Diagnosis Function
When the ECS control unit detects a breakdown, control

CONTROL HOLD
The damping force after changeover is held while
calculated deceleration is over 0.15G and when it falls
below 0.15G, the damping force returns to normal
(SOFT).
Anti-Diving Control
CONTROL START
When the stop light switch goes ON, the ECS control
unit calculates deceleration from the change in vehicle
speed. As a result, after the stop light goes ON, if
deceleration calculated within 0.4 sec. exceeds 0.15G,
the shock absorber damping force is changed to
MEDIUM.
If the stop light switch is ON and the computed degree
