HELP me SUPER SLUETHS: ABS/Brake/Traction Lights!

[SumpChump]

Several dummy lighys lighting my dash like a christmas tree...

Brake / ABS / VSC traction control Light

2008 Scion xB 140k . Been working fine, no recent brake work. All brakes working, even parking brake (and it releases fine, no detectable hang)
Drives good, no curb impacts not animal hits no puddle ramming, no hi-pressure car wash, no offroading, no road debris strikes. Just maybe a world famous Milwaukee pothhole or two. No violent pothole hits though. Stock rims and tires been in place since rotated 2-3k miles ago.
Driven today on cold dry wisconsin roads 200 highway miles. All went fine, not a hit of a problem.
Car sat at my destination for 2 hours. Later, I Get in to go for a famous Kopp's burger... lights pop on. Car still drives and brakes fine. But I'd sure like to have VSC not disabled because it really does help in winter.

My Actron scanner shown no faults or codes. I have done two more short drives and shutdowns to see if the computer can shake this off, nope, lights still on dash. All rims feel cool, all diasks and calipers feel fine, no weird smells, no "hot" smells.

Any thoughts?

You probably lost a front wheel sensor. Probably its wiring flexing and breaking internally. Does your scanner do ABS? I think probably not.

You should also check your brake fluid, as the red brake light isn't cool at all.

No ABS on scanner features. Brake fluid almost prefect full and clear and clean. Just checked after your post right now.

Does the ABS work ? Lock it up in grass or gravel to check. Cheap scanners don't do ABS.

You might have just thrown a generic OBD code-on my '05 xB, it causes all those lights to light up. Weird that your scanner doesn't show anything?

ABS worked as of 9am as I left my icy neaighborhood street. Here in Milwaukee...street clear of any snow or ice. How about that LOL! Never thought I have a hard time finding ice or snow. Will ha e to test ABS back home up north.

Scanner shows nothing at all.

To clarify my previous post, a red brake light is a "don't drive the car" light. I've seen "brake" lights if the ABS light burns out but yours is still on. Dig deeply...

Brake fluid level sensor faulty?

Just shut the car down. Undid and retightened gas cap. Started up again and....Lights still on so far.

Disconnect battery 10 minutes and try again.

Get under the four corners of the car and check wires carefully. My olds silhouette somehow worked the ABS wire off the lower control arm to a point where it snagged on the ball joint stud and pulled halfway out of the wheel bearing/ hub.

Disconnect neg battery for a few minutes, then, reconnect and start engine.

Drive slow, and turn steering all the way to right and left.

There might be other ways to reset on your particular car.

Some have 20 brake stomps or turn the ign key several times without starting until code shows up where odometer is.

the gas cap trick only works for evap check engine lights

Make sure your brake light switch isn't sticking. On some GM models, the brake switch module will stick and cause those dash light to come on. The car will drive great with no codes. Your rear brake lights may stay on when it sticks, or it may not and just be out of adjustment or need a new module, depending what is used on your car.

Not true on Toyotas. There are a couple including VVT that set these off

Will check it out. I suppose a finger could test it. No brake lights in currently as it sits unoccupied in the driveway right now.
