Description
EBS013TC
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 Mode
EBS013TD
Specification data are reference values.
ECM Terminals and Reference Value
EBS013TE
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.
