    The car starts to brake when I press the accelerator pedal and is clatter, rattle from abs.
    It seems to be engaging regenerative braking unnecessarily. Sometimes additionally blinking VSC/TRC lamp.
    Was reset ABS and dependent systems (ttypical 3+1 lamps on desk, was after repair speed sensor rear wheel), no codes now in Techstream. But sometimes there was still an error C1541. ABS calibration was done, ABS hardware seems ok. Has anyone had similar experiences ?

    Seems to me I might be looking very closely at the skid control ECU it's huge has lots of plugs and is right up there above your gas pedal foot with a bunch of wires sticking out of it that I don't know a person with a size 13 shoe and having a good time listening to music could possibly inadvertently kick something seems highly unlikely but in this day and age I don't rule anything out. The skid control ECU seems to handle a lot more than it might should but that's just the way the design is and given what's going on It just seems like that might be possibly a thing and I'm sure in the manual the test procedures are extensive and will help you rule out any funny business you'll probably need to have a very capable scan tool so you can see sub codes and things like that so if that's not going to be a thing it will probably have to go to somebody that does.
