All Dash Lights On/Blinking & No Speedometer

There were no warning signs this was going to happen as far as I can tell. Got into my truck this morning and every light on the dash was on or blinking. Didn’t even notice it until I pulled out of driveway, so as I slowed down to check, I realized my speedometer isn’t working either. Any ideas to try before I take it in tomorrow?
Thanks!

 

How old is your battery? If original, its time to replace it. Low volts or a bad cell will cause crazy things in a Tundra. If the systems don't get the volts/power they are supposed to get, if it is low, it can set off all sorts of interesting lights and issues. I would check that first, no matter if the truck starts ok and runs, still could be battery about to dump, have the battery load tested.

 

and if the battery tests good, time to borrow a code reader and see what codes it is throwing.

 

Thanks for the replies guys… I appreciate it

my battery is barely 2 yrs old, but definitely could be the issue. They don’t make batteries to last long anymore it seems. I’ll check(probably tomorrow) and back to y’all here

 

When you are looking at the battery, check around for rodent damage to wires in the engine compartment....happens.

 

That’s one thing I was able to do, but I didn’t see anything “jumping out at me” that I was able to notice. I’ll look closer tomorrow when I have more time. Thanks for the reply!

 

Look over on the passenger side lower firewall area where the harness passes through into the cabin, this seems to be a favorite place for them to nest and chomp.
