Put on new wheels and swapped over the pressure sensors on my '13 Rubicon. They worked fine till I left the key on for a week after working on the CB and ran the battery to dead. All charged up fine but the TPS light is on and all four readouts for pressure just show a dash mark. Not zero, just a dash. I do have a Procal and had the pressure threshold lowered to 20ish. Don't really want to try and flash it again as it appears there is no reading from the sensors. Any ideas?
