Service Manual 5008736_55 MFE Engine Managment Module [Diagnostic Software Functions]

The EMM stores valuable information a bout the outboard and its running history. This information can be used for troubleshooting, for checking parts information, and for ma king adjustments to the system.

Use Evinrude Diagnostics software, version 5.1 or higher, 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 Interface Cable (P/N 437955).

1. Diagnostic connector
2. Cover

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. The EMM is turned ON when it begins to receive AC voltage from the stator while the outboard is being cranked.

Diagnostic communications on non-running outboards requires a power supply to the EMM.

Use Diagnostic Power Supply Tool, P/N 587005, to supply power to the EMM. The power supply uses internal 9-volt batteries.

Disconnect the tiller handle harness connector from the engine harness. Connect Power Supply Tool to the engine harness connector. Turn toggle switch to the ON position to power the EMM.

IMPORTANT: Static test s require more power than the internal batteries of the tool can provide. Static tests performed using only the internal power supply batteries will produce false results.

Use Accessory Power Cable Kit, P/N 5008092, to connect an external 12 volt battery to the Power Supply Tool when performing these static tests:

• Fuel pump
• Fuel injector
• Ignition coil
• Oil injector.

If Diagnostic Power Supply Tool, P/N 587005, is not available, a Battery Cable, P/N 584348, can be connected to the engine mounted solenoid. Use accessory Key Switch Assembly, P/N 176408, to control power to the EMM.

Static information is viewed when the outboard is NOT running. Th is includes manufacturing information.

The outboard model and serial numbers displayed on the Identity screen must match the identification label on the outboard swivel bracket.

Identity Screen

The serial number and cylinder location displayed on the Injector Coefficients screen must match the actual cylinder placement for each injector.

008568

Dynamic information is viewed while the outboard is running. Changes in dat a, such as voltages or temperatures, are shown as they happen.

008661

Service codes are saved if an abnormal condition occurs while the outboard is running.

The Occurred Faults scree n of the diagnostics software shows the code number, the number of times the event occurred, and operating hours of first and last occurrences.

008584
Occurred Faults Review Screen

Active Faults

An active fault is a service code t hat currently exists. Active faults become occurred faults only if the outboard is running.

008585
Active Faults Review Screen

Historical Faults

The Historical Faults screen keeps a history of all previously occurred faults, including code number, the number of times the event occurred, and operating hours of the last occurrence. Historical faults cannot be erased.

Static Tests allow diagnostic testing of system components while the outboard is NOT running.

008569A
Static Tests Screen

Ignition Test

Use the diagnostics software to test each ignition circuit. Refer to Static Ignition Test on p. 103.

Fuel Test

Use the diagnostics software to test each fuel injector circuit. Refer to Fuel Injector Static Test on p. 106.

Oil Injector

Use the diagnostics software to test the oil injection pump circuit. Refer to OILING SYSTEM TESTS on p. 163.

Fuel Pump

Use the diagnostics software to test the fuel pump circuit. Refer to Fuel Pump Static Test on p. 106.

Water Injector

This test activates the exhaust water valve solenoid. Refer to Exhaust Water Valve Static Test on p. 108.

Overheat

This test is used to check the “ENG TEMP” or “HOT” circuit of the Engine Monitoring system.

Oil Fault

This test is used to check the “NO OIL” circuit of the Engine Monitoring system.

Check Engine

This test is used to check the “CHECK ENGINE” circuit of the Engine Monitoring system.

Tachometer

This test is used to check operation of the tachometer circuit.

Dynamic test s are performed with the outboard running.

008570B
Dynamic Tests Screen

Ignition Test

This test momentarily disables the ignition and fuel injection circuits to one cylinder. By dropping one cylinder, RPM and running quality change s can be observe d. Refer to DYNAMIC TESTS on

Fuel Test

This test momentarily disables one fuel injector circuit. By dropping on e cylinder, RPM and running quality change s can be observe d. Refer to DYNAMIC TESTS on p. 98.

Prime Oil

This test is used to cycle the oil injection pump for priming the oiling system. Perform this test with outboard running to activate oil injection pump.

Powerhead Break-In

Use the diagnostics software to start break-in oiling after a powerhead rebuild. The break-in oiling program runs for two hours of outboard operation, above 2000 RPM.

008662

1. Break-in oil setting

Use the Ignition Timing screen to check and adjust EMM timing. EMM timing must be synchronized to crankshaft position. Refer to TIMING ADJUSTMENTS on p. 124.

TPS Calibration synchronizes throttle plate opening with throttle position sensor voltage. Calibrate after replacing or adjusting any throttle body or throttle linkage parts. Refer to TPS Calibration on p. 126.

Use the Idle Adjust function to increase or decrease IN GEAR IDLE speed. This adjustment offsets the basic EMM programming and will not set an absolute fixed speed . After the offset is changed, the EMM continues to control engine operation normally. Engine idle speed is not fixed.

008662

1. Idle adjustment

All E-TEC fuel injector s use software programming to compensate for variations in fuel flow. Each injector and its location on the outboard is identified by the EMM. DO NOT install an injector without updating the compensation software.

To install a service injector, cl ick the “Re place” button on the Injector Coefficients screen and select the file for the replacement injector. Refer to Fuel Injector Service on p. 148.

Engine rep orts provide service records and can be used to document the running history of an outboard. Reviewing this information can help identify or resolve some service issues.

Click the print button in a window of the diagnostics software to print engine data, or to export the information to a computer file.
