Schematic of the "Boom Cylinder Extend Limit" Solenoid This diagnostic code is associated with the "Boom Cylinder Extend Limit" solenoid. An FMI 06 diagnostic code means the ECM has determined the current of the solenoid is above normal. For machines equipped with the E-Fence feature, reference Troubleshooting, "E-Ceiling and Cab Avoidance - Troubleshoot"Possible causes for this diagnostic code are:
The solenoid energize circuit is shorted to ground.
The ECM may have failed, but is unlikely.Note: The following test procedure may create other diagnostic codes. Ignore the created diagnostic codes and clear those diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 2420 FMI 06 diagnostic code is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.Note: Poor connections are often the cause of a problem in an electrical circuit. Before performing this procedure, inspect the harness connectors that are involved in the circuit. Verify that all the connections in the circuit are clean, secure, and in good condition. If a problem is found with any of the circuit connections: correct the problem and verify that this diagnostic code is still active, before performing this procedure. Test Step 1. CHECK THE SOLENOID ENERGIZE CIRCUIT FOR A SHORT TO GROUND.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnected the solenoid from the machine harness.
Disconnect the J2 machine harness connector from the ECM.
At the J2 ECM harness connector, measure the resistance from signal contact J2-12 (wire K950-YL) to all of the other contacts used in the harness connector. Expected Result:Each resistance measurement is over 5000 ohms.Results:
YES - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to Test Step 2.
NO - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between J2-12 (wire K950-YL) and the circuit with the low resistance measurement.Repair: Repair the machine harness or replace the machine harness. STOPTest Step 2. CHECK IF THE DIAGNOSTIC CODE REMAINS ACTIVE.
Inspect the harness connectors. Clean the contacts of the harness connectors. Check the wires for damage to the insulation that is caused by excessive heat, battery acid, or chafing.
Perform a 45 N (10 lb.) pull test on each of the wires that are associated with the solenoid circuit.
Reconnect all harness connectors. Make sure that the connectors are fully seated. Observe that the clips for each connector are fastened.
Turn the disconnect switch and the key start switch to the ON position.
Operate the machine.
Check the status of the CID 2420 FMI 06 diagnostic code. Expected Result:The CID 2420 FMI 06 diagnostic code is active. Results:
YES - The CID 2420 FMI 06 diagnostic code is active. The diagnostic code has not been corrected. The ECM may have failed.Repair: Perform this Test Step again. If the problem has not been corrected: use the Caterpillar Electronic Technician service tool, in order to perform a "wiggle test" on the solenoid circuit of
