System Schematic For The K6 RelayThe possible cause of a CID 0446 FMI 12 is an open coil or a shorted coil of the K6 relay.This troubleshooting procedure is for an active CID 0446 FMI 12 or the troubleshooting procedure is for an inactive CID 0446 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 0446 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 0446 FMI 12 is displayed as an active diagnostic code or CID 0446 FMI 12 is displayed as an inactive diagnostic code.Results:
OK - The CID 0446 FMI 12 is active or the CID 0446 FMI 12 is inactive. Proceed to test step 2.
NOT OK - The CID 0446 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 the repair is over twenty minutes, replace the desiccant bag in 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 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. PERFORM A FUNCTIONAL CHECK OF THE RELAY.
Turn the ECS to the OFF/RESET position.
Reconnect the battery negative cable.
Disconnect all wires from RM-19 and RM-5 of the relay module.
Remove fuse "F4" from the relay module.
At the relay module, measure the resistance from RM-19 to RM-5. Make a note of the resistance measurement.
Turn the ECS to the STOP position and push in the emergency stop push button (ESPB). Measure the resistance from RM-19 to RM-5. 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 STOP position.Results:
OK - The resistance measurements are correct. The problem does not exist at this time. The initial problem was probably caused by a
