System Schematic For Electronic Governor Relay (EGR)The GSC+ uses the electronic governor relay (EGR) in order to activate the close-for-rated speed contacts of the electronic governor. When this occurs, the electronic governor will increase the engine speed from the idle speed to the rated speed. The GSC+ activates the EGR when the engine oil pressure is greater than the setpoint for low oil pressure shutdown at idle speed ("P014"). Also, "K1" will be present on the lower display. This closes the relay contacts of the EGR. The output for the electronic governor relay is rated at 1 amp. The EGR is located within the relay module. Note: Whenever the GSC+ activates or the GSC+ attempts to activate the EGR, "K1" is shown on the lower display. When the EGR is not activated, "K1" is not shown.The possible causes of this diagnostic code are listed:
The EGR has an open coil or a shorted coil. The results to this diagnostic code are listed:
If CID 0441 FMI 12 occurs during the activation of the EGR, the ECM will stop the fuel injection and the engine will shut down immediately.
If CID 0441 FMI 12 occurs and the EGR is not activated, the engine will be unable to start. Clear the diagnostic code from the fault log after troubleshooting is complete. The GSC+ treats a CID 0441 FMI 12 as an alarm fault. The active alarm faults are shown on the display when the alarm code key is pressed. The active alarm faults will be displayed when the ECS is placed in any position except the OFF/RESET position. This troubleshooting procedure is for an active CID 0441 FMI 12 or the troubleshooting procedure is for an inactive CID 0441 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 0441 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 0441 FMI 12 is displayed as an active diagnostic code or CID 0441 FMI 12 is displayed as an inactive diagnostic code.Results:
OK - The CID 0441 FMI 12 is active or the CID 0441 FMI 12 is inactive. Proceed to test step 2.
NOT OK - The CID 0441 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 relay module is open for more than twenty minutes replace the desiccant bag which is located within the housing of the GSC+. See Testing And Adjusting, "Relay Module - Replace".
Turn the ECS to the OFF/RESET position.
Disconnect the negative battery cable.
Temporarily, remove the relay module from the GSC+. See Testing And Adjusting, "Relay
