SFI SYSTEM
HINT:
The standard normal voltage between each pair of the
ECM terminals is shown in the table below. The
appropriate conditions for checking each pair of the
terminals are also indicated.
The check results should be compared with the standard
normal voltage for that pair of terminals, listed in the
"STD Voltages" column.
The illustration above can be used as a reference to
identify the ECM terminal locations.
