Schematic of the Cat Data Link Circuit
This diagnostic code is recorded when the Chassis ECM is not sending the necessary parameters to the Transmission ECM at the proper rate. The update rate for parameters that are generated by the Chassis ECM is not correct.The possible causes of this diagnostic code are listed:
The Chassis ECM software is incorrect software.
The Transmission ECM software is incorrect software.
Incompatible software may be installed.
The fuse for the Chassis ECM may have failed.System Response:The machine response is listed:
Some implement functions may not work properly.Note: Ensure that the diagnostic code indicator is active and that the diagnostic code is active.Test Step 1. CHECK THE CHASSIS ECM AND THE TRANSMISSION ECM FOR PROPER SOFTWARE VERSIONS.
Use Caterpillar Electronic Technician (ET) in order to verify that the versions of software are compatible. Expected Result:The proper versions of software are installed on the Chassis ECM and the Transmission ECM.Results:
YES - The versions of software are compatible. Proceed to Test Step 2.
NO - The proper software is not installed.Repair: Flash the proper software to the appropriate ECM. Cycle the Key switch in order to initialize the new software. Ensure that the diagnostic code is no longer active. STOPTest Step 2. RECHECK FOR DIAGNOSTIC CODES.
Ensure that the CID 1273 FMI 14 diagnostic code is active. Expected Result:The diagnostic code is inactive. The diagnostic code indicator is inactive. Results:
YES - The diagnostic code indicator and the diagnostic code are inactive.Repair: Clear the diagnostic code.STOP
NO - The diagnostic code is active.Repair: Ensure that the proper software is installed before replacing the ECM. If the software is correct, replace the Transmission ECM. See the Testing and Adjusting, "Electronic Control Module (ECM) - Replace" section in this manual. If the Brake ECM was just replaced , install a new Chassis ECM. See the Testing and Adjusting, "Electronic Control Module (ECM) - Replace" section of this manual.STOP
