MODULE GP-MESSAGE CENTER 1791730 - Caterpillar

Which Generate This Code:The 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 during engine cranking and running. If setpoint P01 is set to 1, 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 for energized position
1 for stop positionProcedureThe 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 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.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 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 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
