TERMINALS OF ECM
1. CHECK ECM
(a) Measure the voltage of the ECM connector.
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
Specified Condition column. The illustration above
can be used as a reference to identify the ECM
terminal locations.
