    stopped at a rest stop a few days ago.

    creepy car pulled up next to me before i took a nap.

    not sure if i put it into d and inched up away from the person and left it in d. i think the park brake may have been on.

    when i woke a while later, all of the brake lights and anti skid were on (photo in next post)

    i tried to cycle the power, pump the brakes, cycle the park brake etc.

    looked up code scanner - no codes. reset anyways.

    nothing has worked in terms of removing the lights.

    the brakes seem to work fine.

    There definitely must be codes somewhere, but probably not in the engine control module; you need to scan the other modules like ABS module or whatever you can access. Might need a better scan tool if it can't access all modules. But I'm pretty sure at least the yellow ABS light means theres an error code stored, if it stays on in READY mode.

    It's sometimes handy, when no suitable scan tool is nearby, to get the brake system trouble codes using a short piece of wire and counting light blinks, as many posts here detail.

    Funnily, there are also lots of posts that are almost the same, and explain where the diag port is, and where to touch the wires, and which pins, but only as a way to clear the trouble codes.

    ... which, of course, is like leading your horse all the way to water, and then saying don't drink! ....

    Did disconnecting the battery and reconnecting it helped?

    thank you all for your good advice...

    i was called out of town and lost track of this post

    finally got to tampa hybrids... tj used a toyota scanner and found code 1391, brake pump

    tj rightly convinced me the pump is still under warranty and i got it fixed under warranty at the local toyota.
