I'm having an issue with a My CAN bus D on an MC43. It had worked the other day then I had made a program change and now it continually gives me CAN Bus failure faults. I have disconnected the wires so there is no chance of a wiring issue. I have made a simple program that only sends one PGN out and that also fails. I have used known working code that i swapped from Can Bus E and the problem continues on D. This is happening on two different panels that I have. I have to think that it is some type of bug or the MC43 needs to be rebooted in some way but I have already sent a blank program to it.
