ASCD BRAKE SWITCH

ASCD BRAKE SWITCH

Description

INFOID:0000000001089507

When the brake pedal is depressed, ASCD brake switch is turned OFF and stop lamp switch is turned ON.
ECM detects the state of the brake pedal by this input of two kinds (ON/OFF signal).
Refer to

EC-677, "System Description"

for the ASCD function.
