INTERNAL EMM
FUNCTIONS
ROM Verification
The EMM performs a self-test of programming
every time it is turned ON. Service code 15 indi-
cates a programming (software) issue. Repro-
gram the EMM with the correct software program
to correct the problem.
Idle Controller
The idle controller reacts to engine operating con-
ditions. Fuel and ignition timings are altered to
maintain a specific RPM when engine is cold or
warm. The controller is inactive when TPS is
advanced from idle position.
RPM Limiter
This feature of EMM programming prevents
engine damage due to excessive RPM. At 6250
RPM, fuel and ignition to the cylinders is shut off.
Normal operation resumes when engine RPM
returns to the specified range.
Neutral RPM Limiter
This feature prevents engine damage due to
excessive RPM if accelerated in NEUTRAL. Neu-
tral engine speed is limited to 1100 RPM.

ENGINE MONITOR
SYSTEM
An optional engine monitoring system warns the
operator of conditions that could damage the out-
board. The system includes a LOW OIL switch on
the oil tank, a warning horn, a dash-mounted dis-
play, and related wiring.
The outboard's EMM sends information about
monitored functions to:
•
A SystemCheck gauge
•
EMM LED indicators
IMPORTANT:
Evinrude E-TEC 15–30 HP mod-
els provide LOW OIL warning ONLY.
Typical SystemCheck gauges
The EMM activates the warning horn and gauge
displays as follows:
•
LOW OIL means that oil in the tank is at reserve
level (about 1/4 full).
For all other warnings, refer to EMM LED INDICA-
TORS on p. 71.
Refer to the EMM Service Code Chart at the
back of this manual for a complete list of all fault
codes.
