    Was driving a couple weeks ago and VCS, ABS and Brake lights came on along with a non-stop beeping. No longer had brake pressure.
    ABS Actuator was replaced a couple years back with a used one. Before I bite the bullet and get a new one from Toyota wanted to see what you guys thought. I couldn't read the codes using a code reader nor tech stream but these are the blink codes I got:

    C1243
    C1245
    C0206
    C1236
    C1242
    C1311
    C1313
    C1210
    C1241
    C1242
    C1244
    C1252

    Any suggestions?

    a new one or if you're on a tight budget, gamble again on a used one. They're a common failure as they age.

    im on my 3rd ABS actuator pump. the original one lasted 10 years, the toyota factory replacement only lasted 5

    as they get to the point of failure, they start cycling alot. my toyota replacement pump was cycling (under hood rumbling every 5-10 seconds) about 450 times an hour per my counter info. now with new pump, its only cycling around 30-40 times an hour

    when you replaced it with a used one, did you just plug and bleed or did you have to use the techstream software to set it up?

    Can you explain the cycling numbers - 450 times; 30-40 times? What do you mean by this?
