D8T and D9T Track-Type Tractors Caterpillar

When an ECM is replaced, the ECM must be configured. The software is flashed either at the factory or at the time of installation on the machine.

The saved configuration data from the ECM that was replaced will restore the parameters that were configured. If an ECM was replaced and configuration data from the old ECM could not be saved, most factory default parameters load when the software is flashed to the new ECM. Refer to the Troubleshooting, ECM - Replace in this manual for more information.
