Ipdm circuit board was burnt (no start). I ohmed out the burnt spot on the board to 2 connectors (a cm and a cn outlet on the Ipdm). I ordered and installed a new Ipdm, and it starts, but I am getting 30 dtc codes, and the ABS and a/c compressor are not working. Im trying to figure out where the branch circuits from connector cm and cn go. I am beginning to think it’s ecm that burnt up.

A/C stopped working and most of the dash trouble lights left side lite up. Corrected a (P0300 code 8 - random/multiple cylinder) all 8 sparkplug coil packs changed, engine running better than normal.
Need additional troubleshooting before I take it to a repair shop.
