TERMINALS OF ECM

ECM

HINT:

The standard voltage and resistance of each ECM terminal is shown in the table below.

The appropriate conditions for checking each pair of terminals are also indicated. The result of checks should be compared with the standard voltage or resistance for that pair of terminals shown in the "Specified Condition" column

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