I got a question, that I don't think anyone knows, if you clear the DTC's from your PCM or reset your PCM by disconnecting the battery, do you reset the oil change tracking?
There are things stored in non-volatile memory, that do NOT get dumped, even if you disconnect power, stuff like the VIN and mileage, and mileage is a figure constantly being updated.
When you clear DTC's, even keeping power on the PCM, you reset all the emissions monitoring and tests, they have no data stored for them and must be all redone.
