    Can you post a picture of what your dash is doing? Have you scanned all modules on the car for codes? How is the 12V battery doing?

    Seems like I've read this a couple times over the last couple years. Seems to get resolved when an unconnected connector gets found under or behind the inverter.

    Only code is the cat below threshold . And two ABS codes under ABS not the reg codes. That’s all of em theses codes I’ve been driving with for 9 months at approx 46 mpg daily. Why I’ve not been to worried. Just the other week the brake pedal went solid as in no power 1956 4 wheel drum brakes hard two feet on pedal to stop . No abs noises at all . Everything else spot on driving great.. took apart diving vehicle to replace abs pump and accumulator and now cannot generate the 0.. all gs look connected .
