Illustration 1 g01082074
Partial Schematic of the Cat Data LinkThis diagnostic code is recorded when the implement ECM is unable to communicate with the machine's power train ECM through the Cat data link. This diagnostic code is active when the implement control ECM does not receive the information that was expected. The possible causes of this diagnostic code are listed below. The causes are listed in order of probability:
The implement control ECM has failed. There are no serviceable parts within the implement control ECM.
The Cat data link has failed.
The implement control ECM is unable to communicate with the power train ECM.Note: Ensure that the diagnostic code for the implement control ECM is active.Test Step 1. VERIFY THAT THE DIAGNOSTIC CODE IS PRESENT.
Turn the key start switch and the disconnect switch to the OFF position.
Remove connectors J1 and J2 from the ECM and reconnect connectors J1 and J2to the ECM.
Turn the key start switch and the disconnect switch to the ON position.
Clear all inactive diagnostic codes.
Operate the machine.
Check whether CID 0248 FMI 09 is present.Expected Result:The CID 0248 FMI 09 is NOT present.Results:
OK - The diagnostic code is NOT present. Resume normal machine operation.STOP
NOT OK - The diagnostic code remains present.Repair: Exit this procedure and perform this procedure again. If the problem remains, perform CID 0248 FMI 02. See Troubleshooting, "MID 114 - CID 0248 - FMI 02 " .STOP
