    I have a 2019 Tundra and I was driving this morning when boom....a bunch of light came on all of a sudden.
    Trailer brake error
    Pre-collision malfunction
    check engine
    yellow triangle with exclamation mark
    slip indicator light
    and another light that keeps blinking on and off...right above the slip indicator light
    There was no heavy demand or towing involved...normal driving conditions. Im at a loss. Does anyone know what this is or could be??
    I had to upload a video in Youtube because its too much to type....here is the link

    Thank you in advanced...God bless you all!!

    Sounds like you may have had some rodents snacking on a wiring harness. You can check your battery, they’ve been known to cause weird issues when they go bad but not completely bad. Good luck!

    Welcome from NY.

    Try cleaning the emblem on the grille first. Is it raining?

    I had the same thing happen last week. After five start up cycles it disappeared and hasn’t come back. I have 2018 50k hopefully it doesn’t come back. Mine ran fine, never knew there was anything wrong. Try a bunch of start/stops hopefully it clears it up for you like it did me.

    Why? At 39,425 miles you're out of the comprehensive warranty.

    I would pull the codes if possible and if related to the powertrain, maybe take it to the dealership as you should be covered until 60k, but I don't think this is "powertrain" related per say.

    Definitely sounds like it may be rodents.

    Everytime I hear about this I immediately think low voltage.

    so update...
    Checked for damaged wires and no go
    pulled codes and I got 2
    P0172 System Rich
    P0175 System Rich
    I have a cold air intake that I installed about 1 month ago though?????
    someone I know said if I fix those codes (rich codes), meaning if I put original intake box back in all codes will dissapear...because somehow they are all connected...I found this questionable...can anyone confirm or have similar experience?....this is sooo frikin weird...I would have never thought engine codes can trigger trailer brake and pre collision codes????

    The codes stored by the other ECU's are typically engine control system DTC's. Your other ECU's are pretty much pointing the finger at your engine ECU saying, " He did it"!

    I would disconnect battery for a while, let everything reset and then test drive. If the codes take several drive cycles to come back then you can pretty much rule out rodent damage.
