CHARGING SYSTEM TERMINALS OF ECU

  1. TERMINAL INSPECTION

    E263238E01

    1. Measure the voltage and resistance according to the value(s) in the table below.

      Tip:

      The standard normal voltage between each pair of generator control ECU assembly 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 normal voltage for that pair of terminals, displayed in the Specified Condition column. The illustration above can be used as a reference to identify the generator control ECU assembly terminal locations.
