FMI 5 Troubleshooting
Troubleshooting Test Steps Values Results
1. Check The Solenoid.
A. Turn the key start switch and the disconnect switch OFF.
B. Disconnect the solenoid from the machine harness.
C. At the harness connector for the solenoid, install a jumper wire between contact 1 and contact 2.
D. Turn the key start switch and the disconnect switch ON. Do not start the engine.
The FMI 5 diagnostic code changes to an FMI 6 after the jumper wire is installed. OK - The harness is correct. The FMI 5 diagnostic code changes to an FMI 6 when the jumper wire is installed. The solenoid has failed.
Repair: Replace the solenoid.
Proceed to Test Step 3.
NOT OK - The diagnostic code remains active.
Proceed to Test Step 2.
2. Check The Harness For An Open.
A. Turn the key start switch and the disconnect switch OFF.
B. Disconnect the harness connectors from the ECM.
C. The jumper wire remains installed.
D. At the machine harness connector for the ECM, measure the resistance between the signal circuit and return circuit.
Note: For solenoids that return to ground, measure the resistance between the signal circuit at the ECM harness connector and frame ground.
Each reading is less than 5 Ω. OK - The reading is less than 5 Ω. The harness is correct.
Proceed to Test Step 3.
NOT OK - The reading is greater than 5K Ω. The open is in the signal circuit or the return circuit.
Repair: Repair or replace the machine harness.
Note: A resistance that is greater than 5 Ω but less than 5K Ω would indicate a loose connection or a corroded connection in the circuit. A resistance measurement that is greater than 5K Ω would indicate an open in the circuit.
Proceed to Test Step 3.
3. Check If The Diagnostic Code Remains
A. Reconnect all harness connectors. Return machine to normal operating condition.
B. Turn the key start switch and the disconnect switch ON.
C. Clear all diagnostic codes.
D. Operate the machine.
E. Stop the machine and engage the safety lock lever.
F. Check if the diagnostic code is active.
The diagnostic code is no longer present. OK - The diagnostic code does not exist at this time. The initial diagnostic code may have been caused by poor electrical connection or short at one of the harness connections. Resume machine operation.
STOP.
NOT OK - The diagnostic trouble code has not been corrected. If the diagnostic code has not been corrected after performing the procedure a second time, the ECM may require replacement.
Prior to replacing the ECM, always contact the Technical Communicator at your dealership for possible consultation with Caterpillar. This consultation may effect repair time.
Follow the steps in Troubleshooting, "ECM - Replace" if the ECM needs to be replaced.
STOP.
