HSA (Hill Start Aid) System

General Description

The HSA (hill start aid) is the system to retain the brake
force with brake pedal not depressed when the vehicle
is parked, and to automatically release the brake force
when starting the vehicle.
The HSA control unit drives the HSA valve located in the
pipe route between the master cylinder and the wheel
cylinder, to hold/release the brake fluid pressure. Also,
alarm function (activates when the door opened with
HSA operating, when the HSA system has running long
time, when the HSA pressure goes down) and self-diag-
nosis function are equipped with the HSA control unit.
