Measure the voltage according to the value(s) in the table below.
HINT:
The standard 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 voltage for that pair of terminals, which is displayed in the "Specified Condition" column. The illustration above can be used as a reference to identify the ECM terminal locations.
