NOTE:
-
When the VDCCM&H/U is replaced with a new part, be sure to perform the selection-registration operation.

REPLACEMENT
CAUTION:
-
Because the pressure sensor built into the H/U is easily damaged by static electricity, start the operation after performing static electricity
measures.
-
Be careful not to touch the sensors in the H/U to prevent damage.
-
Because the seal of the VDCCM 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 VDCCM, always use new screws.
-
When the sealing surface of the VDCCM or H/U is dirty or damaged and it cannot be cleaned or repaired, replace with a new part.
1) Remove the VDCCM&H/U.
2) To prevent entry of foreign objects and brake fluid leakage, plug the oil pressure port of the VDCCM&H/U using a screw plug, etc.
3) Set the pump motor section of the removed VDCCM&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.
