TERMINALS OF ECM
1. ECM
HINT:
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
inspected. The standard voltage between the terminals
is shown under "Specific Condition".
Use the illustration above as a reference for the ECM
terminals.
