  3. Calculate the clearance between the rear ABS wheel-speed sensor and the ABS sensor rotor using the following formula:

    Clearance (mm {in}) = A-13.9 {0.547}

  4. Verify that the clearance between the ABS sensor rotor and the rear ABS wheel-speed sensor is as indicated below.
    • If there is any malfunction, replace it.
