Numerous can faults reported on this car
c1012 vehicle speed from can
c1013 alternator status from can
d601 undocumented code
u1601 can line

The can pattern on the scope is corrupt, I have tried unplugging just about everything and nothing changes it ?

Cannot find any wires twisted together, do Fiat use this system ?

Car cuts out periodically and won't restart until cooled down, triggering signals are absent when in non start condition, crank sensor is working fine.

Any thoughts welcome.
