ENGINE MANAGEMENT MODULE (EMM) EMM DIAGNOSTICS Oil Injector Use the diagnostic software to test the oil injection pump electrical circuitMonitor the voltage at pin (blue wire) of oil tank connectorVoltage should drop while the static test is active
Dynamic Tests
Dynamic tests are performed with the outboard running
IMPORTANT: Oil injection pump will not activate
on 12 VUse voltmeter to check circuit voltage
Fuel Pump
Use the diagnostic software to test the fuel pumpMake sure the pump is wired correctlyIf the pump activates, the EMM and fuel pump circuit are not at faultIf the pump does not run during the static test, check voltage and continuity of pump circuitRefer to Circulation Pump Resistance Test on p166Fuel pump resistance is approximately to 3
Oil Fault
This test is used to simulate an oil pressure switch circuit malfunction and is used to check the "NO OIL" circuit of the SystemCheck gauge
