Schematic of the Left Forward Pump SolenoidThis diagnostic code is associated with the implement pilot supply solenoid. The FMI 06 means that the ECM has detected that the current for the solenoid circuit s above normal. Conditions that could causes this diagnostic code to be activated are:
The energize circuit of the solenoid is shorted to a ground source.
The solenoid has failed.
The ECM has failed. This is unlikely. System Response:A Level 2 warning will be generated. Functionality is lost in forward direction. Motion in reverse direction is allowed with level 3 active event.Note: Before performing this procedure, inspect the harness connectors that are involved in the 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 this diagnostic code is active before performing this procedure. Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected.Note: The resistance of the solenoid coil should be 27 1.4 ohms at 20 °C (68.0 °F).Test Step 1. CHECK THE SOLENOID
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Observe the status of the diagnostic code.
Disconnect the solenoid with the active diagnostic code from the machine harness. Expected Result:The active CID 1703 FMI 06 diagnsotic code changes to a CID 0358 FMI 05 diagnostic code when the solenoid is disconnected.Results:
YES - The active CID 1703 FMI 06 diagnostic code changes to a CID 1703 FMI 06 diagnostic code when the solenoid is disconnected. The solenoid circuit in the machine harness is correct.Repair: The solenoid has failed. Repeat this test "CHECK THE SOLENOID" in order to verify the solenoid failure. Replace the solenoid.STOP
NO - The CID 1703 FMI 06 diagnostic code remains active. Disconnecting the solenoid did not change the status of the active diagnostic code. The solenoid is not causing the problem.
