ASCD BRAKE SWITCH
ASCD BRAKE SWITCH
Component DescriptionINFOID:0000000001703048
When depress on the brake pedal, 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-28
for the ASCD function.

Wiring DiagramINFOID:0000000001703050
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
