Trace the twisted pairs in the looms (CANBUS) particularly as the loom goes through the engine side wall to the nearside wing.
A chafed wire could be the trouble, also check that the plugs - ABS in particular - are clear of muck/corrosion. Remove plugs very carefully as the pins are tiny.
I had trouble with TC and it turned out to be the plug at the ABS unit!
