The electronic control suspension (ECS) is a system
that automatically switches the damping force char-
acteristics of the four shock absorbers, front and rear, in
three steps (SOFT, MEDIUM and HARD) in response to
driving conditions and the conditions of the road surface.
It is also possible to select two modes (TOUR and
SPORT) according to driver preference. The damping
force is changed by commands from the ECS control
unit; the actuator built into the shock absorbers is
activated and the flow of oil inside the absorbers is
varied.
This system also has a diagnostic function and a failsafe
function for improved serviceability and safety.
