Service Manual 5008732_15-30 HP Engine Managment Module [Internal Sensors]

Sensor inputs and internal EMM controllers are used to control outboard operation. Use Evinrude Diagnostics software to troubleshoot the sensors. Refer to the EMM Service Code Chart at the back of this manual for a complete list of all engine fault codes.

Internal sensors are NOT serviceable. Re programming or replacement ma y be required to resolve internal EMM issues.

Monitors the temperature of the fuel injector driver circuits.

If the EMM temperature exceeds 194°F (90°C) or the circuit fails, the EMM:

If EMM temperature exceeds 212°F (100 °C) or the circuit fails, the EMM:

IMPORTANT: The outboard will not restart until the engine cools below 2 12°F (100°C)and the EMM temperature returns to normal. Refer to SHUTDOWN MODE on p. 58.

If EMM temperature is less than -22°F (-30°C) or the circuit fails, the EMM:

If sensor read s less than -71°F (-57 .4°C) or greater than 313 °F (156°C), a sensor circuit fault is detected and the EMM:

Monitors the EMM’s 55 V alternator circuit.

If system voltage exceeds 57 volts, the EMM:

If system voltage is less than 45 V, the EMM:

Monitors the EMM’s 12 V alternator circuit.

If battery voltage exceeds 15.5 volts, the EMM:

If battery voltage is less than 12.5 V, the EMM:

Monitors the EMM’s 5 V sensor circuit.

If sensor voltage is less than 4.75 volts, the EMM:

Supplies the EMM with barometric pressure reading to compensate for changes in altitude and air density.

If the BP sensor reads less than 13 KPa or greater than 119.0 KPa, or the sensor or circuit fails, the EMM:

If the BP sensor reads less than 70 KPa, the EMM:

If the BP sensor reads greater than 105 KPa, the EMM:

Sensor inputs and internal EMM controllers are used to control outboard operation. Use Evinrude Diagnostics software to troubleshoot the sensors. Refer to the EMM Service Code Chart at the back o f this manual for a complete list of all engine fault codes.

The EMM provides a 5 V DC signal for sensor circuits. It monitors all sensor voltage inputs and compares them to predetermined accept able ranges. Inputs that fall outside of the acceptable range create service codes.

The air temperature sensor monitors the air temperature at the throttle body.

If the AT sensor voltage is out of the expected range, or the sensor or circuit fails, the EMM:
