Cat Data Link connections
This CID 0588 FMI 14 diagnostic code is associated with the communication between the Transmission/Chassis ECM and the Monitoring System (Messenger) that is conducted on the circuit for the Cat Data Link.The FMI 14 means that the Transmission/Chassis ECM is not receiving the expected operating parameter information from the Messenger. The Messenger and the Transmission/Chassis ECM are still communicating over the CAT data link. The possible causes of the CID 0588 FMI 14 diagnostic code are listed below:
The software that is installed on the Messenger is incorrect.
The software that is installed on the Transmission/Chassis ECM is incorrect.
A new ECM has been installed but the ECM is not the correct part.Note: Ensure that the CID 0588 FMI 14 diagnostic code is active before performing this procedure.Test Step 1. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS
Verify that the following information is correct:
The part number of the installed software for the Transmission/Chassis ECM
The part number of the installed software for the Messenger
The part number of the Transmission/Chassis ECM
The part number of the Messenger Note: Contact your dealership's Technical Communicator for the correct part numbers of the hardware and the correct part numbers for the configuration software for your machine. Expected Result:All hardware and software part numbers are correct. Results:
OK - All hardware and software part numbers are correct. Proceed to Test Step 2.
NOT OK - All hardware and software part numbers are NOT correct. Repair: Replace the hardware or software that is incorrect with the correct version. For flashing software, refer to Testing and Adjusting, "Electronic Control Module (ECM) - Flash Program". For replacing ECM modules, refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace"STOPTest Step 2. CHECK THE STATUS OF THE DIAGNOSTIC CODE
Turn the disconnect switch and the key start switch to the ON position.
Operate the machine.
Check the status of the CID 0588 FMI 14 diagnostic code. Expected Result:The CID 0588 FMI 14 diagnostic code is not active. Results:
OK - The CID 0588 FMI 14 diagnostic code is not active. The diagnostic code does not exist at this time. The initial diagnostic code could have been caused by a problem at start-up with one of the controls of the ECM. Resume normal operation.STOP
NOT OK - The CID 0588 FMI 14 diagnostic code is active. The diagnostic code has not been corrected.Repair: Repeat this procedure again and verify that the information is correct.If the cause of the problem is not found, the ECM that has activated the diagnostic code may have failed. Prior to replacing an ECM, always contact your dealership's Technical Communicator for possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the cause of the diagnostic code is not found, replace the ECM that has activated the diagnostic code. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
