DIAGNOSTIC
SOFTWARE 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, P/N 764642,
and a laptop computer to access program infor-
mation.
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 any outside device. Power is normally sup-
plied to the
EMM
when the key switch is ON.
Switched B+ (12 V) is supplied to the engine wire
harness. Current enters the
EMM
at pin 21 (pur-
ple) of the
EMM
J1-B connector.
The
EMM
is also turned ON when it begins to
receive AC voltage from the stator while the out-
board is being cranked.
Static Information
Refers to information viewed when the outboard is
NOT running. This includes manufacturing infor-
mation.
The outboard model and serial numbers displayed
on the
Identity
screen must match the identifica-
tion label on the outboard swivel bracket.
The serial number and cylinder location displayed
on the
Injector Coefficients
screen must match the
actual cylinder placement for each injector.
