DescriptionEBS01KMR
When the gear position is in P or N (A/T), Neutral (M/T), park/neutral position is ON. ECM detects the position
because the continuity of the line (the ON signal) exists.
CONSULT-II Reference Value in Data Monitor ModeEBS01KMS
Specification data are reference values.
ECM Terminals and Reference ValueEBS01KMT
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.
