There have been many questions regarding electrical issues posted in the forum and one of the most common replies goes back to the battery cables and the near universally accepted fact the OEM battery cables are garbage.
So, my question is this, because I'm not sure if I've seen it addressed:
If someone decides to replace their battery cables, how much information is lost when the battery is disconnected? Easier things like radio presets are one thing, but what about information changed via JScan, like tire/wheel sizes, TPM disabled, etc.? In other words, when the battery is disconnected, does the ECM reset to a default value across the board which would require reprogramming everything not stock with JScan?
