C: CAUTION
Please clearly understand and adhere to the follow-
ing general precautions. They must be strictly fol-
lowed to avoid any injury to the person doing the
work or people in the area.
1. OPERATION
•Wear work clothing, including a cap, protective
goggles and protective shoes during operation.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust and dirt.
•Before disconnecting connectors of sensors or
units, be sure to disconnect the ground cable from
the battery.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
•Be careful not to burn yourself, because each
part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shop jacks or rigid racks at the specified
points.
2. OIL
When handling oil, follow the rules below to prevent
unexpected accidents.
•Prepare container and waste cloths when per-
forming work which oil could possibly spill. If oil
spills, wipe it off immediately to prevent from pene-
trating into floor or flowing outside, for environmen-
tal protection.
•Follow all government and local regulations con-
cerning waste disposal.
3. BRAKE FLUID
If brake fluid gets in your eyes or on your skin, do
the following:
•Wash eyes and seek immediate medical atten-
tion.
•Wash your skin with soap and then rinse thor-
oughly with water.
Follow all government and local regulations con-
cerning waste disposal.

draulic Control Unit (VDC-
CM&H/U)
A: REMOVAL
1) Disconnect the ground cable from the battery.
2) Use compressed air to remove moisture and
dust around the VDCCM&H/U.
NOTE:
If the terminals become dirty, it may cause improp-
er contact.
3) Lift the lock lever and Disconnect the VDC-
CM&H/U connector.
CAUTION:
Do not pull on the harness when disconnecting
the connector.
4) Disconnect the brake pipes from the VDC-
CM&H/U.
5) Wrap the brake pipe with a vinyl bag so as not to
spill the brake fluid on the vehicle body.
CAUTION:
If brake fluid is spilled on the vehicle body,
wash it off immediately with water and wipe
clean.
6) Remove the nuts and remove the VDCCM&H/U.
CAUTION:
•The VDCCM&H/U cannot be disassembled.
Do not attempt to loosen the bolts and nuts.
•Do not drop or bump the VDCCM&H/U.
•Do not turn the VDCCM&H/U upside down or
place it sideways during storage.
•Be careful not to let foreign matter enter the
VDCCM&H/U.
•Be careful that no water enters the connec-
tors.
7) Remove the VDCCM&H/U bracket.
B: INSTALLATION
1) Install the VDCCM&H/U bracket.
Tightening torque:
33 N·m (3.3 kgf-m, 24 ft-lb)
2) Install the VDCCM&H/U to the bracket.
Tightening torque:
7.5 N·m (0.76 kgf-m, 5.5 ft-lb)
CAUTION:
Attach so that the protrusion of the stud bolt is
at the position shown in the figure.
3) Connect the brake pipes to their correct VDC-
CM&H/U positions.

4) Connect the VDCCM&H/U connectors.
NOTE:
•Be sure to remove all foreign matter from inside
the connector before connecting.
•Make sure the VDCCM&H/U connector is se-
curely locked.
5) Bleed air from the brake system.
C: INSPECTION
1) Check the condition of connection and settle-
ment of connector.
2) Check the mark used for VDCCM&H/U identifi-
cation.
Refer to “SPECIFICATION” for the identification
mark. Description.>
1. CHECKING THE HYDRAULIC UNIT ABS
OPERATION BY PRESSURE GAUGE
1) Lift-up the vehicle and remove the wheel.
2) Remove the air bleeder screws from FL and FR
caliper bodies.
3) Connect two pressure gauges to FL and FR cal-
iper bodies.
CAUTION:
•Use a pressure gauge used exclusively for
brake fluid measurement.
•Do not use the pressure gauge used for the
measurement of transmission oil. Doing so will
cause the piston seal to expand and deform.
NOTE:
Wrap sealing tape around the pressure gauge.
4) Bleed air from the pressure gauges and the FL
and FR caliper bodies.
5) Perform ABS sequence control.

6) When the hydraulic unit begins to work, first the
FL side performs decompression, hold and com-
pression, and then the FR side performs decom-
pression, hold and compression.
7) Read values indicated on the pressure gauge
and check if the fluctuation of the values between
decompression and compression meets the stan-
dard values. Depress the brake pedal and check
that the kick-back is normal, and tightness is nor-
mal.
8) Disconnect the pressure gauges from FL and FR
caliper bodies.
9) Install the air bleeder screws of FL and FR cali-
per bodies.
10) Remove the air bleeder screws from RL and
RR caliper bodies.
11) Connect two pressure gauges to RL and RR
caliper bodies.
