AUTOMATIC TRANSMISSION SYSTEM TERMINALS OF ECM

A01J61YE01

Tech Tips

Each ECM terminal's standard voltage is shown in the table below.

In the table, first follow the information under "Condition". Look under "Symbols (Terminal No.)" for the terminals to be inspected. The standard voltage between the terminals is shown under "Specified Condition".

Use the illustration above as a reference for the ECM terminals.
