Component DescriptionNBS005QJ
When the brake pedal is depressed, ASCD brake switch (2) is
turned OFF and stop lamp switch (1) is turned ON. ECM detects the
state of the brake pedal by this input of two kinds (ON/OFF signal).
Refer to EC-738, "
AUTOMATIC SPEED CONTROL DEVICE
(ASCD)" for the ASCD function.
