Information:
Which Generate This Code:This diagnostic code is associated with the power supply circuit for the sensors. The FMI 06 diagnostic code means that the Machine ECM has determined that the current is above normal.The possible causes of this failure are listed below:
The "sensor power supply" circuit is shorted to ground.
The sensor power supply has failed.
The Machine ECM has failed. A failure of the Machine ECM is unlikely.Note: The following test procedure may create other failures. Ignore these created failures and clear the failures when the original failure is corrected. Test Step 1. CHECK THE POWER SUPPLY.
Turn the disconnect switch and the key start switch to the ON position. Do NOT start the engine.
Ensure that the service code CID 0269 FMI 06 is active.
Disconnect the travel alarm from the machine harness.
Observe the status of the diagnostic code.Expected Result:The diagnostic code CID 0269 FMI 06 has changed to CID 0269 FMI 05. Results:
YES - The diagnostic code CID 0269 FMI 06 has changed to CID 0269 FMI 05. The circuit is correct. Repair: Replace the power supply.STOP
NO - The failure remains active. Proceed to Test Step 2.Test Step 2. CHECK THE SIGNAL CIRCUIT FOR A SHORT TO GROUND.
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness from the power supply.
Disconnect the machine harness connectors J1 and J2 from the Machine ECM.
At the machine harness connector, measure the resistance from contact J1-24 of the switch panel (wire H856-BR) to all possible source of ground. Expected Result:The resistance measurements should be greater than 5000 ohms.Results:
OK - The resistance measurements were greater than 5000 ohms. The harness is correct. Proceed to Test Step 3.
NOT OK - The resistance is less than 5000 ohms. The harness is incorrect. The short is between the signal circuit (wire H856-BR) and the circuit with the lowest resistance measurement.Repair: Repair the machine harness or replace the machine harness. STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the harness connectors and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn the disconnect switch and the key start switch to the ON position.
Clear all active codes.
Operate the machine.
Observe the status of the diagnostic codes. Expected Result:The diagnostic code CID 0269 FMI 06 is no longer active. Results:
YES - The diagnostic code CID 0269FMI 06 is no longer active. The failure does not exist at this time. Repair: The initial failure was probably caused by a poor electrical connection or a short at one of the harness connections that was disconnected and reconnected. Resume normal machine operation. STOP
NO - The diagnostic code CID 0269 FMI 06 is active. The failure has not been corrected. The ECM has failed. Repair: A failure of the ECM is unlikely. Exit this procedure and perform this CID 0269 FMI 06 procedure again. If the cause of the failure is not found, replace the ECM.STOP
