    I'd think you'd be writing code to slip into some firmware somewhere. So not likely. You have to fool the body module or such . Just messing w immobilizer for keys is enough trouble . Disabling features would be something . The computer aren't that interested or tis alot of work not even heavy modders talk about it . So must not be a thing?

    Sure, every winter with our sensor-less snow tires.

    Appreciate you mean “make the light in the dash go out”, but for me at least, that’s surplus to requirements.

    Otherwise?
    If you're a talented auto tech you can take the dash apart and remove the LED.....
    You can also remove the sensors and use the PVC hack (ask the Googles....)

    Personally I would not disable a tpms system since it could save someone's life - perhaps an innocent traveling with you or in another car.

    If winter tires are the issue, installing Autel Mx sensors that are cloned with your summer tire's sensor ids makes sense.

    However various forums include these disable instructions which apparently work for gen3 and other Toyota models:

    It's done. Connected pins 5 and 6. upload_2025-11-15_16-34-57.jpeg

    It would be easy for you to do. On any Gen 3 Prius, it's the same jumper between pins 5 and 6.

    That's the two wires on the left bottom.

    It took me three days and about nine hours and many removals of the connector block to figure it out.

    I used a short piece of wire from a Cat5 cable, but any piece of 24 ir 22 gauge solid copper wire will do.

    Now that I know, anyone can do it in 20 to 30 minutes with no tools.

    All that's needs to be done is to squeeze the sides of the glove compartment and to hinge it down.

    That provides full access to the TPMS. computer..

    The connector's block doesn't even have to be removed.

    Just insert the ends of the jumper into the back of positions 5 and 6 on the two vertical positions on the lower right.

    If you replace the tires without TPMS sensors with those that have them, just remove the jumper.

    No wire cutting or splicing is necessary.

    With the jumper removed, there is no trace of this modification.

    This would be great for states that would fail a vehicle inspection for a TPMS fault.
