System Schematic For Fuel Control RelayThe contacts for the fuel control relay (FCR) are available for use by the customer. The FCR is located within the relay module. The GSC+ activates the FCR according to the value of setpoint P01. If setpoint P01 is set to 0, the GSC+ activates the FCR. The FCR activates during the engine cranking. The FCR activates when the engine is running. If setpoint P01 is set to 1 (ETS), the GSC+ activates the FCR when the engine is stopped. Note: Whenever the GSC+ activates the FCR, "K7" is shown on the lower display. "K7" is also shown when the GSC+ attempts to activate the FCR. When the FCR is not activated, "K7" is not shown. Also, setpoint P01 selects the type of fuel control solenoid:0 - Energized To Run (ETR)1 - Energized To Stop (ETS)ProcedureThe possible cause of this diagnostic code is an open coil or a shorted coil of the FCR.The following response is the system response to this fault while the engine is running:
If a CID 447 occurs, then any equipment that is connected to RM-15 is deactivated.The following response is the system response to this fault while the engine is NOT running:
If a CID 447 occurs, then any equipment that is connected to RM-15 is not activated.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).
Turn the ECS to OFF/RESET and then turn the ECS to STOP.
Press the alarm codes key.
Observe the upper display. Check that a CID 447 FMI 12 is showing.
If the diagnostic code is not showing, enter the service mode. View the fault log (OP1). Check that the diagnostic code is showing. Expected Result: A CID 447 FMI 12 is showing as a active fault or an inactive fault. Results:
OK: A CID 447 FMI 12 is active or inactive. Proceed to 2.
NOT OK: A CID 447 FMI 12 has not occurred. The fault is NOT active and the fault is NOT inactive. STOP.
Check internal cable of relay module. Note: Only open the relay module in a dry environment. If the inspection takes more than twenty minutes replace the desiccant bag in the GSC+ housing. See Testing And Adjusting, "Relay Module - Replace".
Turn the ECS to OFF/RESET.
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: Reassemble the relay module to the GSC+. Proceed to 3.
NOT OK: Replace the connector clamp if the clamp is missing. If the cable is damaged, replace the GSC+. STOP.
Perform a functional check for the ASR.
Turn the ECS to OFF/RESET.
Disconnect all wires from RM-15 of the relay module.
At the relay module, measure the resistance from RM-15 to RM-4. Resistance should be greater than 5000 ohms.
For ETR systems, turn the ECS to the START position. For ETS systems, turn the ECS to START and then turn the ECS to the OFF/RESET position. Make sure that "K7" is showing in the lower display.
At the relay module, measure the resistance from RM-15 to RM-4. Resistance should be less than 5 ohms.Expected Result: For 3.c, the resistance should be greater than 5000 ohms. For 3.e, the resistance should be less than 5 ohms.Results:
OK: There was probably a poor connection and this troubleshooting procedure corrected the connection. Check the electrical connectors, terminals and wiring. See Testing And Adjusting, "Electrical Connector - Inspect". STOP.
NOT OK: Either one of the resistance measurements are NOT correct. The relay module is faulty. Replace the relay module. See Testing And Adjusting, "Relay Module - Replace". STOP.
