Schematic for the solenoids associated with the Implement ECM J1 Connections for Implements
Note: The diagram above is a simplified schematic of the electrical circuit. The schematic is electrically correct. However, not all of the possible harness connectors are shown. Refer to the latest revision of the Electrical Schematic for the complete schematic.Diagnostic Trouble Code Procedure
Note: Prior to beginning this procedure, inspect the harness connectors that are involved in this circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure, and in good condition. If a problem with a connection is found, correct the problem and verify that the diagnostic code is active before performing a troubleshooting procedure. For sensors powered via the fuse panel, check the condition of the appropriate fuse before beginning the troubleshooting procedure.

Troubleshooting Test Steps Values Results
1. Identify Active FMI Code Associated With Solenoid Circuit Code present. FMI 3 diagnostic code, proceed to Test Step 2.
FMI 5 diagnostic code, proceed to Test Step 3.
FMI 6 diagnostic code, proceed to Test Step 5.
FMI 13 diagnostic code, proceed to Test Step 8.
Begin Process For FMI 3 Troubleshooting Here
2. Check The Machine Harness For A Short
A. Turn the key start switch and the disconnect switch OFF.
B. Disconnect the harness connection at solenoid.
C. Disconnect J1 and J2 connectors from ECM.
D. Measure the resistance of suspect solenoid contact signal wire to all J1 and J2 contacts.
Each reading is greater than 5K Ω. OK: All resistance readings are greater than 5K Ω.
