System Schematic For The Fuel Control RelayThe GSC+ uses the fuel control relay (FCR) in order to activate the fuel control solenoid (FCS). The GSC+ also uses the fuel control relay (FCR) in order to provide power to the optional electronic governor (EG). The FCR is located within the relay module. The fuel control solenoid is located in the fuel system of the engine. The electronic governor (EG) is located on the subpanel.Some generators use the ETR type of fuel system. In the ETR type of fuel system, the GSC+ activates the FCR. The FCR energizes the fuel control solenoid in order to RUN the engine.Note: There is another type of fuel system which is called energized to shutdown (ETS). In the ETS, the GSC+ activates the FCR. The FCR energizes the fuel control solenoid in order to SHUT DOWN the engine.Note: Whenever the GSC+ activates the FCR or attempts to activate the FCR, "K7" is shown on the lower display. When the FCR is not activated, "K7" is not shown. Also, setpoint P001 selects the type of the fuel control solenoid. 0 = ETR. 1 = ETS.The possible cause of a CID0447 FMI 12 is an open coil or a shorted coil of the FCR.The system responses to these diagnostic codes are listed below.
If a CID 0447 FMI 12 occurs and the engine is running, a CID 0566 FMI 07 will become active. A CID 0566 FMI 07 describes an unexpected shutdown. The shutdown mode is functioning. The engine stops.
If a CID 0447 FMI 12 occurs and the engine is NOT running, then the engine can not start or the engine can not run.The GSC+ treats a CID 0447 FMI 12 as an alarm fault. Active alarm faults are shown on the display when the "Alarm Codes" key is pressed. Also, the ECS must be in any position except the OFF/RESET position. Clear the diagnostic code from the fault log after troubleshooting is complete.This troubleshooting procedure is for an active CID 0447 FMI 12 or the troubleshooting procedure is for an inactive CID 0447 FMI 12.Test Step 1. CHECK THE STATUS OF THE DIAGNOSTIC CODE.
Turn the ECS to the OFF/RESET position and then turn the ECS to the STOP position.
Press the "Alarm Codes" key.
Observe the upper display. Check that the CID 0447 FMI 12 is active.
If the diagnostic code is not active, enter the Service Mode. View the fault log for a OP1. Check that the diagnostic code is inactive.Expected Result:A CID 0447 FMI 12 is displayed as an active diagnostic code or CID 0447 FMI 12 is displayed as an inactive diagnostic code.Results:
OK - The CID 0447 FMI 12 is active or the CID 0447 FMI 12 is inactive. Proceed to test step 2.
NOT OK - The CID 0447 FMI 12 has not occurred. The diagnostic code is not active and the diagnostic code is not inactive. Stop.Test Step 2. CHECK THE INTERNAL CABLE OF THE RELAY MODULE.Note: Only open the relay module in a dry environment. If the inspection and repair takes more than approximately twenty minutes replace the desiccant bag in the GSC+ housing. See Testing And Adjusting, "Relay Module - Replace".
Turn the ECS to the OFF/RESET position.
Disconnect the battery negative cable.
Temporarily, remove the relay module from the GSC+. See Testing And Adjusting, "Relay Module - Replace".
Check the cable that attaches the relay module to the GSC+.Expected Result:The cable should be firmly seated in the connector. The clamp should be in place. The cable should not be damaged.Results:
OK - The cable is firmly seated in the connector. The clamp is in place. The cable is not damaged. Reassemble the relay module to the GSC+. Proceed to test step 3.
NOT OK - One or more of the components are damaged or the components are missing.Repair: Replace the clamp if the clamp is missing. If the cable is damaged, replace the GSC+. See Testing and Adjusting, "EMCP Electronic Control (Generator Set) - Replace". Stop.Test Step 3. FUNCTIONAL CHECK OF THE FCR
Turn the ECS to the OFF/RESET position.
Reconnect the battery negative cable.
Disconnect all wires from RM-15 and RM-4 of the relay module.
Remove fuse "F3" from the relay module.
At the relay module, measure the resistance from RM-15 to RM-4. Make a note of the resistance measurement.
Turn the ECS to the START position and push in the emergency stop push button (ESPB). Measure the resistance from RM-15 to RM-4. Make a note of the resistance measurement.Expected Result:The initial resistance measurement after removing the wires and the fuse from the relay module should be greater than 5000 ohms. The resistance measurement should be less than 5 ohms when the ECS is placed in the START position.Results:
OK - The resistance measurements are correct. The problem does not exist at this time. The initial problem was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal operation and watch for a recurrence. Stop.
NOT OK - Either one of the resistance measurements are NOT correct. The relay module has failed. Repair: Replace the relay module. See Testing And Adjusting, "Relay Module - Replace". Stop.
