HINT:

The standard normal voltage 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 normal voltage for that pair of terminals, displayed in the STD Voltages column.

The illustration above can be used as a reference to identify the ECM terminal locations.
