Can bus pins on ECU

[Stuart W]

I have yet another electrical issue on my 2015 grand picasso blue hdi.It now intermittently throws up a fault which disables most functions and illuminates many fault lights. Even the rev counter goes to zero and the engine won't turn off.Diagbox shows communication issues with ECU/BSI/ABS.Clearing all faults on diagbox works for a few days..... does anyone know the ecu pins which carry the canbus signal? The fault is intermittent and canbus signals look normal when scoped
