Quite a mess of errors on the powertrain bus there, but nothing strikes me as an obvious source.

Exactly. When cleared only glow plugs would remain and then at random all would appear. I'm guessing one of the modules would interrupt can com and throw a chain of errors, but which module?

I will say like that :

ABS show error because ECU errors , then ACC show merror

then PDC show error because of that


when look closer- seems like ECU could be "defective"
glow Plug modules is not "open circuit" it show "short to ground" so if all wires are ok and glow plug, perhaps module itself is defective , or ecu can not control it in proper way

start from glow plug module , wires , glow plug first

Glow plug module is not on can network so I doubt it will be causing the issues.
From what I gathered owner already tried to disconnect radar but same effect. He also tried run on a different engine ecu with same effect.
So if its not airbag module, engine ecu or the radar... would that be abs module? Any way to pinpoint it?
