-
The standard voltage and resistance between each pair of ECM terminals 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.
