DIAGNOSTIC
SOFTWARE FUNCTIONS
The EMM st ores valuable inf ormation a bout the
outboard and its running history. This info rmation
can be used for trou bleshooting, fo r checking
parts in formation, and for ma king adjustme nts to
the system.
Use Evinrude Diagnostics software, version 5.1 or
higher, and a laptop computer to access progra m
information.
IMPORTANT: For software help, refer to the
“Help” menu in the software.
Communication
Locate the diag nostic connector on th e engine.
Remove the cover and install the Diagnostic Inter-
face Cable (P/N 437955).
Connect the 9-pin connector of the interface cable
directly to the computer’s serial port.
The EMM must turn ON before it will communicate
with the computer.
ELECTRIC START MODELS
Power is normally supplied to the EMM when the
key switch is ON. Switched B+ (12 V) enters the
EMM at pin 28 (purple) of the EMM J1-B connec-
tor.
The EMM is also turn ed ON when it begins to
receive AC volt age from the stator while the out-
board is being cranked.
ROPE START MODELS
Diagnostic co mmunications on non-ru nning rope
start models requires a power supply to the EMM.
Use Diag nostic Power Supply T ool, P/N 587005,
to supply power to th e EMM. The power supply
uses internal 9-volt batteries.
Disconnect the tiller handle harn ess co nnector
from the e ngine harness. Con nect Power Supply
Tool to the engine harness connector. Turn toggle
switch to the ON position to power the EMM.
IMPORTANT: Static test s require more p ower
than the internal batte ries of the t ool can provide.
Static te sts perf ormed using only the interna l
power supply batteries will produce false results.
Use Accessory Power Cable Kit, P/N 5008092, to
connect a n externa l 12 volt bat tery to the Power
Supply Tool when performing these static tests:
• Fuel pump
• Fuel injector
• Ignition coil
• Oil injector
