Diagnostic Soft-
ware Functions
The EMM stores valuable information about the
outboard and its running history. This information
can be used for troubleshooting, for checking
parts information, and for making adjustments to
the system.
Use Evinrude Diagnostics software, version 5.1 or
higher, and a laptop computer to access program
information.
IMPORTANT:
For software help, refer to the
“Help” menu in the software.
Communication
Locate the diagnostic connector on the 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 turned ON when it begins to
receive AC voltage from the stator while the out-
board is being cranked.
Rope Start Models
Diagnostic communications on non-running rope
start models requires a power supply to the
EMM .
Use Diagnostic Power Supply Tool, P/N 587005,
to supply power to the
EMM . The power supply
uses internal 9-volt batteries.
Disconnect the tiller handle harness connector
from the engine harness. Connect Power Supply
Tool to the engine harness connector. Turn toggle
switch to the ON position to power the
EMM .
IMPORTANT:
Static tests require more power
than the internal batteries of the tool can provide.
Static tests performed using only the internal pow-
er supply batteries will produce false results.
Use Accessory Power Cable Kit, P/N 5008092, to
connect an external 12 volt battery to the Power
Supply Tool
when performing these static tests:
•
Fuel pump
•
Fuel injector
•
Ignition coil
