Description
The Engine Management Module (
EMM)
is a
water-cooled engine controller. It controls many
outboard systems including alternator output for
the 12 V and 55 V circuits. Operating voltage is
supplied to the
EMM
by the stator.
This section discusses the functions of the
EMM
and its various internal and external sensors. It
also describes using
Evinrude
Diagnostics
soft-
ware to retrieve and adjust service information
saved in the
EMM
EMM
Functions
The EMM
controls the following processes and
functions:
•
Alternator output; 55 V and 12 V
•
Start Assist Circuit (SAC) voltage boost
•
Fuel and ignition timing and duration
•
Fuel injector activation
•
Oil injector pump activation
•
Electric fuel pump control
•
Idle speed control
•
RPM limiter
•
Electrical circuit monitoring
•
Service code creation and storage
•
Warning system activation
•
ROM verification, self-test
•
Choke-less cold starting
•
Output of diagnostic data
•
Tachometer signal
•
RPM profile and engine hours
•
Oiling ratios
•
Shift interrupt function
•
Anti-knock compensation
EMM
Connections
IMPORTANT:
EMM
connections and wiring
must be clean and tight. Improper electrical con-
nections can damage the
EMM
. DO NOT run the
outboard with loose or disconnected wiring.
Make sure
EMM
connections are clean and tight.
•
Engine wire harness to
EMM
connectors; J1-A,
J1-B, J2
•
Stator to
EMM
connections; one 6-pin
AMP
and
J2 connector.
LED Indicators
The
EMM
has LED indicators located next to the
electrical connectors that provide information
related to various electrical circuits.
IMPORTANT:
LED 1 is toward the top of the out-
board (Closest to
EMM
J2 connector).
When the ignition key is turned ON, LEDs 1, 3 and
4 should light, indicating that the SAC circuit, sen-
sor circuits, and the stop circuit are working.
As the outboard is being started, all four LEDs
should light and then go off in sequence. If any of
the LEDs does NOT light during starting, refer to
When the outboard is running, all LEDs should be
off. If any LED is lighted while the outboard is run-
ning, refer to
