SPACER 3422622 - Caterpillar

Illustration 1 g01196560
Schematic of the Cat Data Link CircuitThis diagnostic code is recorded when the power train ECM can not communicate properly with the Caterpillar Monitoring System ECM. A portion of the Data Link information requested by the ECM is not being received.The possible causes of this diagnostic code are listed:
The power train ECM has the incorrect software installed.
The Caterpillar Monitoring System ECM has the incorrect software installed.
Incompatible software may be installed.Test Step 1. CHECK THE POWER TRAIN ECM AND THE CATERPILLAR MONITORING SYSTEM 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 Caterpillar Monitoring System ECM and the power train 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 Ensure that the diagnostic code is no longer active. Stop.Test Step 2. RECHECK FOR DIAGNOSTIC CODES.
Ensure that CID 0562 FMI 14 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 power train ECM. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace". If the power train ECM was just replaced, install a new Caterpillar Monitoring System ECM. See Testing and Adjusting, RENR8846, "Electronic Control Module (ECM) - Replace" for the machine that is being serviced. Stop.
