ABS Control Module and Hydraulic Control Unit (ABSCM&H/U): Replacement

CAUTION:
  • Because the seal of the ABSCM cannot be replaced, do not pull or peel it by lifting it up.
  • Because the screw of the H/U will become slightly worn in every replacement procedure, 5 times is the maximum number of times for replacement. If a problem is found such as not being able to torque the screw to specifications even before 5 replacement operations are performed, replace the H/U body.
  • When installing the ABSCM, always use new screws.
  • When the sealing surface of the ABSCM or H/U is dirty or damaged and it cannot be removed or repaired, replace with a new part.
  1. Remove the ABSCM&H/U bracket. < Ref. to REMOVAL , ABS Control Module and Hydraulic Control Unit (ABSCM&H/U). >
  2. To prevent entry of foreign objects and brake fluid leakage, plug the oil pressure port of the ABSCM&H/U using a screw plug, etc.
  3. Set the pump motor section of the removed ABSCM&H/U face down on a vise.
    NOTE: Before securing a part in a vise, place cushioning material such as wood blocks, aluminum plate or cloth between the part and the vise.

  5. Slowly pull out the ABSCM upward from the H/U.
    NOTE: To prevent damaging of coil section, remove the ABSCM straight up from H/U without twisting.
  6. Make sure there is no dirt or damage on the sealing surface of the H/U.
    CAUTION:
    • Do not clean the ABSCM & H/U by applying compressed air.
    • Even if damage is found on the H/U seal, do not attempt repair by filing or with a metal scraper. To remove the seal residue, always use a plastic scraper. Do not use chemical such as paint thinner, etc., to clean.
  7. Position the coil of the new ABSCM to align with the H/U valve.
  8. To prevent deformation of the ABSCM housing cover, hold the corner of ABSCM and install it to the H/U without tilting.
  9. Using a TORX® BIT E5, attach/tighten new screws in the order of (1) through (4).
    CAUTION: Always use new screws.
