Component DescriptionEBS00N9Z
When the gear position is “P” (A/T models only) or “N”, park/neutral position (PNP) switch is “ON”.
ECM detects the position because the continuity of the line (the “ON” signal) exists.
CONSULT-II Reference Value in Data Monitor ModeEBS00NA0
Specification data are reference values.
ECM Terminals and Reference ValueEBS00NA1
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.
