check ECU next stop?

mine did that. several times. kept a close eye on the gauges but never had any problems running it long enough to get it back to the terminal and get whatever it was fixed each time. 2012 vnl630.

it was a sign of things to come though. many different mental illnesses in the ecu after that. it ended up being replaced. then almost every sensor under the hood started failing one at a time. they had to be replaced, some multiple times. they ended up up keeping the truck local and giving me a new freightliner it was spending so much time in the shop just so it would be close when the next thing failed or had to be replaced.

all of this started happening around 200k on the clock seemed that was the design life for most of the electrical components.

as long as theg auges show good and there are no noticeable issues I'd run it till I got it to the shop to have it checked out.

welcome to the wonderful world of Volvo and it's electrical system lol
