Illustration 1 g00516860
Schematic For The Sensor Power SupplyThe EMCP II + has a sensor supply voltage of 8 DCV from the GSC+ that powers the engine sensors. The sensors that are displayed in illustration 1 may vary. The sensors may vary according to the engine. See table 1 in order to determine the sensors on your engine.
Table 1
Sensor     EIS Engines     Engines with an ECM    
Coolant Temperature     Yes     No    
Oil Pressure     Yes     No    
Coolant Loss     Yes     Yes    
Oil Temperature     No     Yes    The engine oil temperature sensor is optional. The engine coolant fluid level sensor is optional.The sensor power supply functions whenever power is applied to the GSC+.The GSC+ is usually programmed in the factory. The GSC+ handles a diagnostic code that is associated with the sensor power supply as an alarm fault. P004 = 0. If the GSC+ is programmed to shutdown, P004 is equal to 1 for a problem with the sensor power supply. It is not necessary to press the "Alarm Codes" key in order to view the CID 0269 FMI 04. The CID 0269 FMI 04 is automatically shown on the upper display.Diagnostic codes are created when the harness connector is disconnected from the GSC+ during these troubleshooting procedures. Clear these created diagnostic codes after the particular problem is corrected and the particular diagnostic code is cleared. The possible cause of a CID 0269 FMI 04 occurs when the voltage of the sensor supply is less than 7.5 DCV.Begin performing these procedures only when CID 0269 FMI 04 is active and the "DIAG" indicator is FLASHING on the upper display. The GSC+ treats a CID 0269 FMI 04 as an alarm fault. Active alarm faults are shown on the upper display when the "Alarm Codes" key is pressed and the engine control switch (ECS) is in any position except the OFF/RESET position. For an inactive diagnostic code, the problem may be intermittent. To troubleshoot an inactive diagnostic code, use the preceding system schematic and see Testing And Adjusting, "Electrical Connector - Inspect". Clear the diagnostic code from the fault log after the troubleshooting procedure is completed.Test Step 1. CHECK THE GSC+.
Turn the ECS to OFF/RESET.
Disconnect the harness from the GSC+.
Turn the ECS to STOP.
Press the "Alarm Codes" key.
Observe the upper display for the CID 0269 FMI 04. If the diagnostic code is displayed then the problem is active.Expected Result:The CID 0269 FMI 04 should NOT be showing on the upper display.Results:
OK - The GSC+ is functioning properly. Therefore, the engine harness or a sensor has failed. Proceed to test step 2.
NOT OK - The GSC+ has failed. Repair: Replace the GSC+. See Testing And Adjusting, "EMCP Electronic Control (Generator Set) - Replace". Stop.Test Step 2. VERIFY THE TYPE OF ENGINE
Select the appropriate engine in order to determine the proper test sequence.Expected Result:Select the appropriate engine.Results:
PEEC - Test the engine sensor circuit for PEEC engines. Proceed to test step 3.
MUI - Test the engine sensor circuit for MUI engines. Proceed to test step 4.
EUI - Test the engine sensor circuit for EUI engines. Proceed to test step 7.Test Step 3. CHECK THE OIL TEMPERATURE SENSOR
Turn the ECS to OFF/RESET.
Reconnect the harness connector to the GSC+.
Disconnect the engine harness from the oil temperature sensor.
Turn the ECS to STOP.
Press the "Alarm Codes" key.
Observe the upper display for the CID 0269 FMI 04.Expected Result:If the sensor is the cause of the CID 0269 FMI 04, then CID 0269 FMI 04 should NOT be showing when the sensor is disconnected.Results:
OK - The CID 0269 FMI 04 is NOT active. The oil temperature sensor has failed.Repair: Replace the oil temperature sensor and verify that the new sensor corrects the problem. Stop.
NOT OK - The CID 0269 FMI 04 is still active. The oil temperature sensor is not the cause of the CID 0269 FMI 04. Proceed to test step 4.Test Step 4. CHECK THE COOLANT LOSS SENSOR
Turn the ECS to OFF/RESET.
Reconnect the harness connector to the GSC+.
Disconnect the engine harness from the coolant loss sensor.
Turn the ECS to STOP.
Press the "Alarm Codes" key.
Observe the upper display for the CID 0269 FMI 04.Expected Result:If the sensor is the cause of the CID 0269 FMI 04, then CID 0269 FMI 04 should NOT be showing when the sensor is disconnected.Results:
OK - The CID 0269 FMI 04 is NOT active. The coolant loss sensor has failed.Repair: Replace the coolant loss sensor and verify that the new sensor corrects the problem. Stop.
NOT OK - The CID 0269 FMI 04 is still active. The coolant loss sensor is not the cause of the CID 0269 FMI 04. Proceed to test step 5.Test Step 5. CHECK THE OIL PRESSURE SENSOR
Turn the ECS to OFF/RESET.
Reconnect the harness connector to the GSC+.
Disconnect the engine harness from the oil pressure sensor.
Turn the ECS to STOP.
Press the "Alarm Codes" key.
Observe the upper display for the CID 0269 FMI 04.Expected Result:If the sensor is the cause of the CID 0269 FMI 04, then CID 0269 FMI 04 should NOT be showing when the sensor is disconnected.Results:
OK - The CID 0269 FMI 04 is NOT active. The oil pressure sensor has failed.Repair: Replace the oil pressure sensor and verify that the
