    ASC light on

    Good Evening and Marry Christmas anybody.
    I tryied search similar case with no succes.I am having a very strange problem with ASC.
    I get light on steady as soon as the engine exceeds 1000 RPM and it keeps staying on continuosly.
    I performed the Asc test and the lights blinks 8 times and based on defect description it should be left rear abs valve.Do you have any suggestion about?Why it illuminates with engine rpm increasing?
    Thank you for any help

    If it is 1000 RPM and NOT moving that's strange - if it's 1000 RPM in gear and moving it makes sense....

    Thank you did not realize the image was turned.....
    I am trying anything with no succes but before buying parts i want to be sure of what problem i have.
    I found asc module under driver foot and it seems to be ok(at least with interior visual inspection).
    I don t know where to find pin 81 or 83 now i am gonna give a look to the asc module schematic and see to find out something more about.
