    Hi Folks, have 2011 Prius. Was working fine and suddenly got ABS light. Brakes are jammed and even after pushing on brake pedal, it’s very hard to apply brakes. Did scan the codes, got c1203, c1252,c1253, c1256 and c1345.
    ABS is NOT making frequent rattling noise and this is fairly new ABS system which I replaced last year. So, not sure what’s the problem. I tried to clear the codes, however, the codes are not going away. 12v battery was read and it came at 11.7v. Did recharge this 12v battery and also tried connecting this 12v battery to other car battery by jump start cable. Still nothing improved and got same codes. Also tried bleeding all 4 brakes, but still no improvement. Please provide suggestions.

    So let's be clear last year or whenever it was not too long ago you replaced what The actuator and the other part both pieces is recommended by Toyota? Or you just replace the piece that folks told you to replace one or the other that may be your problem Toyota recommends both pieces be replaced obviously with new so if you're buying used and only replacing the one piece well that may be part of the issue I've been waiting to find out it this can happen again especially in this model that's why I'm asking about what you bought and what you replaced and with and how thanks.
