- LED 1 – Light ON, charging output malfunction 12 V or 55 V circuit; or SAC overcurrent “CHARGING FAULT”
- LED 2 – Light ON, Injector or ignition circuit malfunction, “INJECTOR/IGNITION FAULT”
- LED 3 – Light ON, Sensor/5 V circuits, “SENSOR FAULT”
- LED 4 – Light ON, “NO OIL/OVERHEAT FAULT”
Refer to EMM DIAGNOSTICS on p. 104 for additional diagnostic information.
Software Programs
The Evinrude Diagnostics Software program can be used to communicate with the EMM Communication also requires a 12 V supply to power up the EMM.
Refer to EMM DIAGNOSTICS on p. 104 for additional diagnostic information. Identify and resolve all problems related to Stored Faults/Codes prior to clearing the codes.
