    Now Yesterday went to my tlruck Volvo 780 2007 753000mi. Cummins and guess what:the truck was making the sound when ignition is on, checking the transmission differential s and trailer abs was blinking every few seconds, WITHOUT KEY IN IGNITION. I drove sevral hours no change, after 2 more hours only the abs lamp on the trailer was blinking and the check sound on the trailer.I disconet the batteries just in case.Forgot, I tried restarting the computer no change. No codes either.
