System Schematic For Electronic Governor Relay (EGR)The GSC uses the electronic governor relay (EGR) to signal the engine ECM to begin injection. The GSC activates the EGR when the engine oil pressure is greater than the setpoint for low oil pressure shutdown at idle speed (P14). The GSC activates the EGR. (Also, "K1" is showing 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 the EGR, "K1" is shown on the lower display. "K1" is also shown on the lower display when the GSC attempts to activate the EGR. When the EGR is not activated, "K1" is not shown.ProcedureThe following condition is a possible cause of a CID "441" FMI "12".
A coil is open on the EGR.
A coil is shorted on the EGR.The following response is the system response to this fault while the EGR is activated:
If a CID 441 FMI 12 occurs, then the engine ECM stops the fuel injection. Also, the engine will shut down immediately.The following response is the system response to this fault while the EGR is not activated:
If a CID 441 FMI 12 occurs, then the engine is unable to start or the engine is unable to run.The GSC treats this diagnostic code as an alarm fault. Active alarm faults are shown on the display when the alarm codes key is pressed. Also, the active alarm faults are shown when the ECS is in any position except the OFF/RESET position. Clear the diagnostic code from the fault log after troubleshooting is complete.
Check the status of the diagnostic code (Active/Inactive).
