BRAKE SWITCHPFP:25230
DescriptionEBS0125Z
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 ModeEBS01260
Specification data are reference values.
ECM Terminals and Reference ValueEBS01261
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.

PNP SWITCHPFP:32006
DescriptionEBS01265
When the gear position is in Neutral, park/neutral position is ON. ECM detects the position because the conti-
nuity of the line (the “ON” signal) exists.
CONSULT-II Reference Value in Data Monitor ModeEBS01266
Specification data are reference values.
ECM Terminals and Reference ValueEBS01267
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.
