ABS
D: REPLACEMENT
CAUTION:
• Because the seal of the ABSCM cannot be re-
placed, 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 re-
placement. If a problem is found such as not
being able to torque the screw to specifications
even before 5 replacement operations are per-
formed, 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
ABS-6, REMOVAL, ABS Control Module and Hy-
draulic Control Unit (ABSCM&H/U).>
2) To prevent entry of foreign objects and brake flu-
id leakage, plug the oil pressure port of the AB-
SCM&H/U using a screw plug, etc.
3) Set the pump motor section of the removed AB-
SCM&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.
4) Using TORX
®
BIT E5, remove the four screws of
ABSCM.
NOTE:
These screws cannot be reused.
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 seal-
ing 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.
Tightening torque:
1.5 N·m (0.15 kgf-m, 1.1 ft-lb)
10) Check that there is no foreign matter in mating
surface between the ABSCM & H/U.
11) Using a TORX
®
BIT E5, tighten the screws in
the order of (1) through (4) again.
Tightening torque:
3 N·m (0.3 kgf-m, 2.2 ft-lb)
12) Check that there is no gap in the mating sur-
face between ABSCM & H/U.
