EC-1234
[YD (WITH EURO-OBD)]
BRAKE SWITCH
BRAKE SWITCH
PFP:25230
Description
EBS013HU
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.
CONSULT-II Reference Value in Data Monitor Mode
EBS013HV
Specification data are reference values.
ECM Terminals and Reference Value
EBS013HW
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.
