My 2016 Volvo 780 has ECU on fault code, engine light on, cruise not working. Dealer found no code while in shop. Any ideas where to check for issue correction? Truck running fine so far.

 

Did you ever find out what the problem was?

 

I just got the code too....2012 Volvo VNL64T670.


Check engine light. And it says Check Engine ECU

Ughhh
