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