Software Replacement
Software programs or “maps” are downloaded into the EMM prior to factory testing of the outboard. Periodically, a new map may be available to enhance the operation of an outboard. Refer to the installation instructions provided with the program.
IMPORTANT: Software replacement requires the use of “Bootstrap” Tool, P/N 586551.
EMM Transfer
EMM Transfer is a feature that allows EMM replacement. Use the diagnostic software program and follow the “help info” instructions provided in the program.
IMPORTANT: Whenever the EMM is replaced, timing verification must be performed. Refer to Timing Verification on p. 143.
SystemCheck ENGINE MONITOR
The SystemCheck engine monitor warns the operator of conditions that could damage the engine. The monitoring system consists of a dash mounted gauge with four light emitting diodes (LED), a warning horn, sensors on the engine and oil tank, and related wiring. The system is compatible with all Evinrude outboards with the Modular Wiring System (MWS).
Gauges are available in two sizes: a 2-in. gauge with four LEDs or a 3 1/2-in. tachometer with LEDs.
2-Inch Gauge
3 1/2-Inch Tachometer
The system logic is provided by a microprocessor in the gauge. The microprocessor connects to the EMM and the oil level sending unit of the oil tank.
Refer to the EMM Service Code Chart located at the back of this manual for a detailed list of service codes related to SystemCheck activation.
The EMM will activate the warning horn and the appropriate LED on the gauge as follows:
• NO OIL light indicates an oil delivery problem such as an empty oil tank or damaged oil system components.
• WATER TEMP or HOT light indicates an engine or EMM overheat condition.
• CHECK ENGINE light is used to indicate numerous fault conditions identified by EMM.
The oil tank sending unit will activate the warning horn and the LOW OIL LED of the gauge.
• LOW OIL light indicates the oil level in the oil tank is down to the reserve level (about 1/4 full).
System Self-Test
During engine start-up, pause with the key switch in the ON position. The horn self-tests by sounding a half-second beep. The gauge self-tests by turning the indicator lights on simultaneously, then off in sequence. This self-test routine might occur more than once during start up if battery voltage drops to 7 V. Self-test repeats if the key switch is turned OFF and ON.
Service Mode
SystemCheck goes into a service mode if the key is left ON after self-test (engine NOT running). All light circuits and sensors are active, but the horn is not. Grounding the appropriate light circuit wire will turn the light on, but the horn will not sound.
Engine Running
All warning light circuits are active when the engine is running. A microprocessor in the gauge monitors the tach circuit and activates the horn circuit when engine speed exceeds 500 RPM. The gauge will continue monitoring until the engine stops.
SystemCheck warnings activate the horn for 10 seconds and the appropriate gauge light for a minimum of 30 seconds. This allows adequate time for the operator to look at the gauge after hearing the horn. If the failure is momentary (e.g., oil moving in the tank), the light will remain ON for the full 30 seconds before going out. If the fault continues, the light remains ON until the key is turned OFF or the failure is corrected. The warning will reoccur at the next start-up if the problem is not corrected.
