3) Set the pump motor section of the removed VD-
CCM&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
VDCCM.
NOTE:
These screws cannot be reused.
5) Slowly pull out the VDCCM upward from the H/U.
NOTE:
To prevent damaging of coil section, remove the
VDCCM 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 VDCCM&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 VDCCM to align with
the H/U valve.
8) To prevent deformation of the VDCCM housing
cover, hold the corner of VDCCM 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 VDCCM&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 VDCCM&H/U.
13) Install the VDCCM&H/U to the vehicle.
14) Bleed air from the brake system.
15) Perform the selection•registration operation of
parameter. <Ref. to VDC(diag)-18, PARAMETER
SELECTION, OPERATION, Subaru Select Moni-
tor.>
NOTE:
• After replacing the VDCCM, be sure to perform
the selection•registration operation of parameter.
• For the selection and registration of parameter,
the Subaru Select Monitor is required.
• When no data is registered, ABS/EBD/VDC
warning light illuminates and the DTC “Parameter
selection failure” is detected.
16) Check the parameter to confirm that the ap-
plied models and grades of the relevant vehicle are
included. <Ref. to VDC(diag)-18, PARAMETER
CHECK, OPERATION, Subaru Select Monitor.>
17) If the applied models and grades of the relevant
vehicle are not included, perform the selection•reg-
istration operation of parameter with the {Confirm
Parameter} screen again. <Ref. to VDC(diag)-18,
PARAMETER SELECTION, OPERATION, Subaru
Select Monitor.>
18) Execute Clear Memory after parameter selec-
tion and registration operations because the DTC
for “Parameter selection failure” is memorized.
