    I have a 2008 Tundra SR5 4WD CrewMax. About a minute after shutting the truck off, the key buzzer, power door locks, keyless entry, and door lights shut off. I am trying to diagnose and fix this issue. It may be unrelated but my TPMS, traction control, and airbag lights are all on as well.

    Have you checked the battery?

    I don’t believe it’d be the battery, truck has never failed to start and been doing this since I bought it in November 2018.

    It sounds like those things are somehow tied to the auto timer for the interior lights, mine shut off after 30 seconds, but it is a configurable setting via Techstream. Unless the ECU is smart enough to shutdown non essential systems if it senses the battery voltage drop below acceptable parameters, someone else might know.
    It does sound like you need to have someone with Techstream, or similar system, take a look at the ECU since your TPMS, Trac, and ABS lights are on. It may be a simple Zero Point Calibration needed. Toyota service centers and some automotive repair places have access to Techstream, and devices that can perform the troubleshooting needed. There are a couple repair shops by me that can do Toyota ECU troubleshooting, but not sure if they use Techstream or something else. Or find someone on here that is close by that has a copy of Techstream.

    I have the same problem. It occurred when I disconnect the battery. To trouble shoot why my cab lights weren't working any more...I do have flashing lights on my instrument panel.
