Hello, want to apologize for the long post but I am trying to include all of the information.

Initially this building took a power hit and we found issues with the CWIL. The P24A pico was blown and saw an obvious burn mark on the U13 chip. We replaced the CWIL.

Upon replacement, it was still showing offline with a DCN. We troubleshot the CAN back to the IOD and found only 15 ohms between CCL and CCH with con3 unplugged. I also had faults of 1920 and 1922. So both the IOD and CPUA were replaced.

With those replaced and software loaded on the CPUA, I now have 120 ohms on my CAN terminals. Unfortunately the problem remains. DCN shows maincop1 offline. On the CWIL, stat b is blinking erratically. On the IOD, both NPBAD and SPBAD LED’s are on. Tried an SPC and it says SP offline. Still have 1920 and 1922 faults.

Thanks in advance for any info!
