Every light on my dash is on. What could this be from?

    I own a 2015 Toyota tundra Limited. I got in my truck this morning and when I cranked my truck, every single light on my dash was on. My check engine light, brake, ABS, auto LSD, traction control, and the 4 LO and 4 HI lights are blinking. On top of that, my RPM and speed gauges are stuck at zero. It appears my whole dash has just gone haywire, does anyone know what could be causing this?

    For reference, that photo was taken while I was going about 30 mph.

    Your truck isn't even on so those will all be on since the ignition is turned to the on position I'm assuming. Start the truck and see what happens

    Wait i just saw the 30mph deal.

    Rodent damage maybe? Pop the hood pull the engine cover and look at all wiring.

    Check your battery state of charge and health. Seen that with a battery going bad or with a bad cell but not dead. If you don't have a way to check, most of the auto parts stores can do it for free and most will give you a little print out so you know they aren't just trying to sell you a battery.

    I have a similar issue on mine except it's not drive-able at all right now. A little investigating and I found the chewed up wiring. Tow truck comes to pick it up tomorrow...

    Guess we found another difference between the 2nd and 3rd Gen Tundra's. When everything on the 3rd gen is working perfectly the gas gauge doesn't. Even with a hailstorm of electrical issues, the 2nd gen gas gauge is spot on. IMG_9234.jpg

    I had that on my 2008 and it was the mass air sensor ... I don't know if that is the case for you but maybe worth a look.

    The indicator lights can be used to help figure out the cause of the issue.

    Having the exact same issues, was told it was a possible exam failure. Following for more advice.
