Schematic of the Solenoid for the Engine/Fuel Shutdown Solenoid This diagnostic code is recorded when the ECM reads the voltage of the solenoid circuit as being above normal.The possible causes for this diagnostic code are listed:
The circuit of the solenoid is shorted to the +battery circuit.
The Machine ECM has failed. This situation is unlikely.Note: Ensure that the CID 0017 FMI 03 for the solenoid is active.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes now, but clear those codes after the original diagnostic code has been corrected. Note: Poor connections are often the cause of a problem in electrical circuits. Before performing this procedure, inspect all of the harness connectors involved in the circuit. Verify that all of the connections in the circuit are clean, secure, and in good condition. If a problem is found with any of the connections: correct the problem and verify that diagnostic code CID 0581 FMI 03 is still active, before performing the following procedures. Test Step 1. CHECK THE SOLENOID CIRCUIT FOR A SHORT TO THE +BATTERY CIRCUIT.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness from the "Fuel Shut Off" solenoid.
Disconnect the machine harness connectors J1 and J2 from the Machine ECM.
Measure the resistance from the signal contact J2-1 (wire A982-BR) to all contacts that are used in the machine harness connectors for the ECM.Expected Result:The resistance should be greater than 5000 ohms for each measurement.Results:
OK - The resistance is greater than 5000 ohms for each measurement. The machine harness is correct. Proceed to Test Step 2.
NOT OK - The resistance is NOT greater than 5000 ohms for each measurement. The resistance is NOT correct. There is a short in the machine harness. The short is between signal contact J2-1 (wire A982-BR) and the circuit with the low resistance measurement.Repair: Repair the harness or replace the harness.STOPTest Step 2. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the contacts and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn the disconnect switch and the key start switch to the ON position.
Clear all inactive diagnostic codes.
Operate the machine.
Observe the status of the diagnostic code for the solenoid.Expected Result:The diagnostic code for the solenoid is NOT present. Results:
YES - The diagnostic code is NOT present. The diagnostic code does not exist at this time. Repair: The initial diagnostic code was probably caused by a poor electrical connection or a short at one of the disconnected and reconnected harness connectors. Resume normal machine operation.STOP
NO - The diagnostic code has not been corrected. The Machine ECM may have failed.Repair: A failure of the ECM is unlikely. Exit this procedure and perform this diagnostic code procedure again. If the cause of the diagnostic code is not found, replace the ECM. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
