TERMINALS OF ECM
Each ECM terminal’s standard normal voltage is shown in the table below.
In the table, first follow the information under ”Condition”. Look under ”Symbols (Terminals No.)” for the termi-
nals to be inspected. The standard normal voltage between the terminals is shown under ”STD Voltage”.
Use the illustration above as a reference for the ECM terminals.
