BRAKE SWITCH
BRAKE SWITCH
PFP:25230
DescriptionEBS01KML
STOP LAMP SWITCH
The stop lamp switch is installed to brake pedal bracket. The switch
senses brake pedal position and sends an ON-OFF signal to the
ECM. The ECM uses the signal to control the fuel injection control
system.
ASCD BRAKE SWITCH (MODELS WITH ASCD)
When depress on the brake pedal, 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 toEC-355, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)"for the ASCD function.
CONSULT-II Reference Value in Data Monitor ModeEBS01KMM
Specification data are reference values.
ECM Terminals and Reference ValueEBS01KMN
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.
