Heat freaking ???

I was doing a bit of casual traffic control work yesterday (04/12/2019) near the new satellite suburb of Harrington Park - at 2.30pm it was a uncool 41 degrees, at 3.15 when I got knocked off and told to go home my indicators were on double time - as if the trailer connection was on with no trailer - once it cooled down after around 30 k's of driving all went back to normal -- has anyone else had this phenomena happen to them ??
It's especially perplexing as I had every ECU checked for possible "cold solder joints" while the vehicle was being "built" by 4X4 Offroad and we thought that we had found and rectified all of them, - 51 were found to be suspect on the various PCB's - maybe a few have been missed or some of the internal resistors or capacitors (?) just don't like getting overheated. I know on the Freightliner cab over (B-Double) I used to occasionally drive a few years back the diesel fuel passed through a huge alloy heatsink in the main engine ECU just to cool it down.
