I’ve got 2 ecus, both with a fault code 3 and 7. I’m assuming there is an issue with a shared line. What is the typical error for this type of code? I’ve changed all caps in the ecu once received, but on the sim these codes still throw. Also does anyone have a source for a p28 schematic I remember bromac or something, but I’m sure that options long gone now.

Just figured it out. It was the trace connecting c19 and l2 closest to the plugs. Filled in that break and problems are both gone.
