2007 Tundra Dash Lights Flashing

I was towing a 12’ loaded box trailer and also had the bed loaded through the mountains in PA on I80. On a long uphill slog the rpm’s were held constant at around 4000 for awhile. During that a bunch of the lights on the dash started flashing (sorry, I don’t know which ones). The truck kept going.

Don’t know if it’s related but when I stopped for a nap, I had no sign of life when trying to restart- turned out the battery housing was loose and moving around, tightening did the trick.

Related? I haven’t had any codes read yet. Thanks.

 

Probably related. It would be nice to know which dash lights flashed. When the CEL flashes its trying to tell the driver to let off the throttle because far too much fuel is not being burned yet you did not indicate any engine missing, right?

 

No engine missing, it just powered through.
