Yes. They will also be lost if the battery drops below 12v.

The engine computer (next to the battery) is also the regulator.

disconnect your battery and touch the cables together then let the car sit with the battery disconnected for 30min

Follow the positive battery cable from the battery. It will lead you to the starter.

I believe you can unhook the pos and neg battery terminals for 10 mins to achieve this. Might also be able to pull the ecm/pcm fuse.
