ENGINE MANAGEMENT MODULE (EMM)
S.A.F.E. WARNING SYSTEM
S.A.F.E. WARNING
SYSTEM
The
S.A.F.E.
(
Speed Adjusting Failsafe Electron-
ics
) warning system alerts the operator and pro-
tects against engine damage from the following
abnormal conditions:
Activation
When one of these conditions occurs, the
EMM
interrupts fuel injector and ignition operation,
reducing engine speed to
1200 RPM. The warning
horn sounds and an Engine Monitor message dis-
plays. When
S.A.F.E.
is active, the engine will run
normally below 1200 RPM. Above 1200 RPM, the
engine will shake excessively.
Recovery
The engine will operate in
S.A.F.E.
as long as the
fault condition exists. To recover normal operation,
two conditions must be met:
•
Sensor or switch readings must be back within
limits
•
The
EMM
must be reset—stop and restart
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. 174.
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 stored
service code is resolved (code 29 and 31) and the
code is cleared using diagnostics software (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 stored service
code. Use
Evinrude Diagnostics
software to clear
a code 57 or 33.

ture above expected range

Code 57 High RPM with low TPS setting
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 explo-
sion.
