The ASC-ECU judges whether the brake is applied
suddenly or not according to the stop lamp switch
"ON" signal sent from the stop lamp switch and the
frequency signal in proportion to the rotation speed
of each wheel sent from the wheel speed sensors. If
the ASC-ECU judges that the brake is applied sud-
denly, it sends the ESS activation request signal to
the ETACS-ECU. When the ETACS-ECU receives
the ESS activation request signal, it makes the
turn-signal lamps flash quickly.
