BELT TIGHTENER GP 3488109 - Caterpillar

This CID 0296 FMI 14 diagnostic code is associated with the communication between the Implement ECM and the Transmission/Chassis ECM. The communication is conducted on the Cat Data Link circuit or the communication that is conducted over the SAE J1939 Data Link circuit.The FMI 14 means that the Implement ECM is communicating with the Transmission/Chassis ECM on the involved data link circuit. However, the Implement ECM is not receiving expected operating parameter information.A "companion" diagnostic code is activated when the CID 0296 FMI 14 diagnostic code is activated by the Implement ECM. The "companion" diagnostic code indicates the data link that is involved. The "companion" diagnostic code that has been activated will be either of the following diagnostic codes:CID 0247 FMI 14 - SAE J1939 Data LinkCID 0248 FMI 14 - Cat Data LinkDetermine the "companion" code that is activated simultaneously with the CID 0296 FMI 14 diagnostic code to determine which data link is involved.Note: The "companion" code of the data link is cleared when the CID 0296 FMI 14 diagnostic code is cleared. The possible causes of the CID 0296 FMI 14 diagnostic code are listed below:
The software that is installed on the Transmission/Chassis ECM is incorrect.
The software that is installed on the Implement ECM is incorrect.
A new ECM that is installed is not the correct part.Note: Ensure that the CID 0296 FMI 14 diagnostic code is active before performing this procedure.Test Step 1. DETERMINE THE COMPANION CODE OF THE DATA LINK THAT IS ACTIVENote: Both of the "companion" codes of the data link are active, if an incorrect software or an incorrect control module causes the problem.
Check the list of active diagnostic codes in order to determine the "companion" diagnostic codes that are active. CID 0247 FMI 14 - SAE J1939 Data LinkCID 0248 FMI 14 - Cat Data LinkResults:
OK - The CID 0248 FMI 14 diagnostic code is active indicating that the problem is in the Cat Data Link. In order to perform the troubleshooting procedure for the Cat Data Link, proceed to Test Step 2.
OK - The CID 0247 FMI 14 diagnostic code is active indicating that the problem is in the SAE J1939 Data Link. In order to perform the troubleshooting procedure for the SAE J1939 Data Link, proceed to Test Step 2.Test Step 2. VERIFY THE HARDWARE AND THE SOFTWARE PART NUMBERS
Verify that the following information is correct:
The part number of the installed software for the Implement ECM
The part number of the installed software for the Transmission/Chassis ECM
The part number of the Implement ECM
The part number of the Transmission/Chassis ECM Note: Contact the Technical Communicator at your dealership for the correct part numbers of the hardware and the software configuration 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 3.
NOT OK - All hardware and software part numbers are not correct. Repair: Replace the hardware or software that is incorrect with the correct version.
