There is even the chance that if we had tried to manually remate the original ecm, the original problem might have gone away, but since the new one was mated to my vehicle, I owned it--no returns. The calculates the amount of ash and the pressure increase the ash generates in the diesel particulate filter. The original multi-displacement system turned off opposite pairs of cylinders, allowing the engine to have three different configurations and displacements.
