Location of theTilt Cylinder Retract SolenoidThis diagnostic code is associated with the Tilt Cylinder Retract Solenoid. The FMI 03 means that the ECM has determined that the voltage of the solenoid circuit is above normal.The possible causes of this diagnostic code are listed:
Solenoid failure.
Solenoid circuit shorted to a +power supply.
Machine ECM failure. ECM failure is unlikely. 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. Ensure that the diagnostic code of CID 2241 FMI 03 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.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 solenoid and the ECM.
At the machine harness connector for the ECM, measure the resistance from contact J1-59 (wire M929-WH) to all contacts that are used in the machine harness connectors for the ECM.Expected Result:Each resistance measurement should be greater than 5000 ohms.Results:
OK - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to test step 2.
NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between contact J1-59 (wire M929-WH) and the circuit with the low resistance measurement. Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK THE OPERATION OF THE ECM.The disconnect switch and the key start switch remain in the OFF position. The machine harness connectors for the solenoid and the ECM remain disconnected.
At the J1 connector for the ECM, use a wire removal tool to remove wire M929-WH from contact J1-59.
Reconnect the machine harness J1 connector to the ECM.
Turn the disconnect switch and the key start switch to the ON position.
Observe the status of the active diagnostic code.Expected Result:The FMI 03 changes to an FMI 05 after the wire is disconnected.Results:
YES - The FMI 03 changes into anFMI 05 after disconnecting the wire. The ECM has responded correctly to the condition of an open circuit. Reinstall the disconnected wire to the correct space in the ECM connector before proceeding to the next Test Step. Proceed to Test Step 3.
NO - The FMI 03 remains active. The status of the active diagnostic code did not change when the wire was disconnected from the ECM.Repair: The ECM has not responded correctly to the condition of an open circuit. The operation of the ECM is not correct. Prior to replacing an ECM, always contact your dealership for possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the ECM requires replacing, refer to Troubleshooting, "Electronic Control Module (ECM) - Replace".STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE IS STILL ACTIVE.
Inspect the harness connectors. Clean the contacts of the harness connectors and check the wires for damage to
