I have never seen that before. Typically its always a NODE error on the hall boards. Never had a car board issue like that. Possible the board behind cop has shifted and the botton is not making connection with micro switch. Have had that. Does the button light up at all when you push it? But that does not explain why the rocker switch is messed up. Have you ever tried dumping the LON memory by removing and shorting the Cap on the IC board?
