Conditions Which Generate This Code:
Illustration 1 g01936514
Connections of the transmission solenoid 5This diagnostic code is associated with the transmission 5 solenoid valve. The FMI 03 means that the ECU has determined that the voltage of the solenoid circuit is above normal.The possible causes of the diagnostic code are listed:
The solenoid has failed.
The energize circuit of the solenoid is shorted to the +battery circuit.
The ECU has failed. This 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 1405 FMI 03 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.Test Step 1. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT TO THE +BATTERY CIRCUIT.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connectors from the solenoid and the ECU.
At the machine harness connector for the ECU, measure the resistance from contact J1-58 (wire 900-PU) to all contacts that are used in the machine harness connectors for the ECU.Expected Result:Each resistance measurement is 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 J1-58 (900-PU) and the circuit that has a low resistance measurement.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 2. 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 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 circuit.
Reconnect all of the harness connectors in order to make sure that the connectors are fully seated. Also, make sure that the clips for each connector are completely fastened.
Turn the disconnect switch and the key start switch to the ON position.
Operate the machine.
Determine if the CID 1405 FMI 03 is active.Expected Result:The CID 1405 FMI 03 is active.Results:
YES - The CID 1405 FMI 03 is active. The problem has not been corrected.Repair: It is unlikely that the ECU has failed. Exit this procedure and perform this procedure again. If the cause of the diagnostic code is not found, replace the ECU. Prior to replacing an ECU, always contact your dealership's Technical Communicator for possible consultation with Caterpillar. This consultation may greatly reduce repair time. See Testing and Adjusting, KENR8292, "Electronic Control Unit - Replace".STOP
NO - The CID 1405 FMI 03 is not active. The problem does not exist at this time.Repair: The initial diagnostic code was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation.STOP
