    Did you ever have the 12v tested?

    I test d the 12v was 12.2 v
    Regardless I changed the battery 2 days ago. It's a new 12v battery now.
    All eror and displays disappear after I'm turning the car on/ off several times. It is ok now.
    I will try to replace the pump motor relay (c1253).

    This post by Patrick might be worth a read . He has a njinja rep in this forum, even if he hasn't been around much lately.

    The post above was only a hint. Hinting that it could be in your best interest to get a 2 day sub to the repair manual, or try to get blink codes from the brake ECU.

    My problem here is intermittent. Right now I don't have any dtc .
    The fusible link is just an array of fuses. Not a relay.i might be wrong .
    They sell it at the dealership for 30$.
    I don't have any blown fuses now. And car functions 100%. But I do have a feeling this problem will come back because I only changed the battery which yet tested good (12.2v) but was 6 yrs old . when this abs failure happens it sudden and it takes 1 minutes for the car to be ok again after turning on/off several times . Yet very dangerous for me. I don't think problem is gone.
