Shutdown Mode
Outboard “shutdown” will occur if specific faults
are detected by the
EMM .
Conditions that initiate shutdown
Code 57 occurs when the EMM detects abnor-
mally high RPM relative to the TPS position. This
condition could be caused by uncontrolled fuel
entering the combustion cycle. Before removing
the code and STARTING the outboard, find and
repair the cause.
•
Perform Fuel System Pressure Test on p. 143.
Check for external fuel leakage that could allow
fuel and/or vapor to enter the engine through
the air intake.
•
Check for internal fuel leakage from a leaking
injector or vapor separator vent hose.
Recovery
To recover from shutdown mode, the EMM must
NOT detect the related fault at start-up. The out-
board will not restart until the cause of the
occurred service code is resolved (code 29 and
31) and the code is cleared using diagnostics soft-
ware (code 33 and 57). Then, the
EMM must be
turned OFF and ON again.
IMPORTANT:
Shutdown related to code 57 or 33
requires the removal of the Occurred service code.
Use Evinrude Diagnostics software to clear a code
57 or 33.
Diagnostic Soft-
ware Functions
The EMM saves 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.
Power is normally supplied to the EMM when the
key switch is ON. Switched B+ (12 V) enters the
EMM at pin 21 (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.

WARNING
If the engine shuts OFF and the “CHECK
ENGINE” light or EMM SENSOR FAULT LED
is flashing, the engine cannot be restarted. A
hazardous fuel condition may exist which
could result in a fire or explosion.
Code 29 Excessive EMM temperature
Code 31 Excessive engine temperature
Code 33 Excessive NO OIL condition
Code 57 High RPM with low TPS setting
