MANUAL TRANSAXLE SYSTEM TERMINALS OF ECM


  1. ECM

    A001WF9E15

    Tech Tips

    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.
