EMM DIAGNOSTICS

times the event occurred, operating hours of first
and last occurrence.
Hard Faults
A hard fault is a code that currently exists. Hard
faults become stored faults only if the outboard is
running.
Persistent Faults
The Persistent Faults screen provides a history of
all previously stored codes, including code num-
ber, the number of times the event occurred, and
operating hours of the last occurrence.
Persistent faults cannot be erased.
Static Tests
Static Tests perform diagnostic testing of speci-
fied components.
Ignition Test
Use the diagnostic software to test each ignition
circuit. Refer to Static Spark Test on p. 128.
Check each ignition circuit for continuity between
the EMM and individual coil. Check the resistance
of the ignition coil windings. Refer to IGNITION
COIL TESTS on p. 141.
Fuel Test
Use the diagnostic software to test each fuel injec-
tor. The injector should make an audible click.
Make sure the injector being monitored is wired
correctly. If the injector activates, the EMM and
injector circuits are not at fault. If the fuel injec-
tor(s) will not fire during the diagnostic tests,
check the continuity of the injector circuit. Refer to
Fuel Injector Resistance Test on p. 185.
