this can be caused by having different sized wheels on the front vs the back.

Get an abs code reader and see what code it thru. That is true about having different size wheels on front and back will cause it too.

Usually when all of those lights come on at once it's due to a defective ABS block(EBCM)... one located under the hood.

I'm the original owner and I'm at 137,000 miles. I have had the above codes come on and off for a couple of months, and have since replaced the front wheel hub assembly's that included wheel sensors, replaced alternator, and "just" cleaned the rear sensors for the first time, one had a strand of wire stuck to it (wire not in photo below).

Cleared codes, I'll have to drive it for about a week and see if codes come back, hopefully it was just the dirty rear sensors.
