I agree with that, do a DCN, likely MAINCOP is offline. Have you checked the CWIL fuses like the faults suggest? If either CAN voltage is off, start disconnecting devices on the car CAN channel to find which device is the problem. Also, a PA4 board is the heavy duty version for the larger 1/2 hp AC motors. The new version is PA7, PA6 is undersized if you have that motor. Oh and the PA4 board had 2 actual resistors for the CAN termination but the PA6 has 2 jumpers. Make sure those are off or you’ll only have 40 ohms on the CAN channel.
