SHUTDOWN MODE
Outboard “shutdown” will occur if specific faults are detected by the EMM:
| Code 29 | Excessive EMM temperature |
| Code 31 | Excessive engine temperature |
| Code 33 | Excessive NO OIL condition |
| Code 57 | High RPM with low TPS setting |
Code 57 occurs when the EMM detects abnormally high RPM relative to the TPS position. This condition could be caused by uncontrolled fuel entering the combustion cycle. Before removing the code and STARTING the outboard, find and repair the cause.
- Perform Fuel System Pressure Test on p. 153. Check for external fuel leakage that could allow fuel and/or vapor to enter the engine through the air intake.
- Check for internal fuel leakage from a leaking injector or vapor separator vent hose.
If the engine shuts OFF and the “CHECK ENGINE” light or EMM SENSOR FAULT LED is flashing, the engine cannot be restarted. A hazardous fuel condition may exist which could result in a fire or explosion.
Recovery
To recover from shutdown mode, the EMM must NOT detect the related fault at start-up. The out board will not restart until the cause of the stored service code is resolved (code 29 and 31) and the code is cleared using diagnostics software (code 33 and 57). Then, the EMM must be turned OFF and ON again.
IMPORTANT: Shutdown related to code 57 or 33 requires the removal of the stored service code. Use Evinrude Diagnostics software to clear a code 57 or 33.
DIAGNOSTIC SOFTWARE FUNCTIONS
The EMM stores valuable information about the outboard and its running history. This information can be used for troubleshooting, for checking parts information, and for making adjustments to the system.
Use Evinrude Diagnostics software, P/N 765011, and a laptop computer to access program information.
IMPORTANT: For software help, refer to the “Help” menu in the software.
Communication
Locate the diagnostic connector on the engine. Remove the cover and install the Diagnostic Inter face Cable, P/N 437955.
- Diagnostic connector
Connect the 9-pin connector of the interface cable directly to the computer’s serial port.
The EMM must turn ON before it will communicate with the computer.
ELECTRIC START MODELS
Power is normally supplied to the EMM when the key switch is ON. Switched B+ (12 V) enters the EMM at pin 3 (purple) of the EMM J1-A connector.
The EMM is also turned ON when it begins to receive AC voltage from the stator while the outboard is being cranked.
