VDC Control Module & Hydraulic Control Unit (VDCCM&H/U)
VEHICLE DYNAMICS CONTROL (VDC)
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.
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.

12) Bleed air from the brake system.
13) Bleed air from RL and RR caliper bodies, and
pressure gauge.
14) Perform ABS sequence control.
15) When the hydraulic unit begins to work, first the
RR side performs decompression, hold and com-
pression, and then the RL side performs decom-
pression, hold and compression.
16) Read values indicated on the pressure gauge
and check if the fluctuation of the values between
decompression and compression meets specifica-
tion. Depress the brake pedal and check that the
kick-back is normal, and tightness is normal.
17) Disconnect the pressure gauge from the RL
and RR caliper bodies.
18) Install the air bleeder screws of RL and RR cal-
iper bodies.
19) Bleed air from the brake system.
2. CHECKING THE HYDRAULIC UNIT ABS
OPERATION WITH THE BRAKE TESTER
1) Set wheels other than the one to measure free
rollers.
2) Prepare for the ABS sequence control operation.
3) Set the front wheels or rear wheels on the brake
tester and set the select lever position to the “N”
range.
4) Operate the brake tester.
5) Perform ABS sequence control.
6) When the hydraulic unit begins to work, check
the following work sequence.
(1) The FL wheel performs decompression,
hold and compression in sequence, and subse-
quently the FR wheel repeats the cycle.
(2) The RR wheel performs decompression,
hold and compression in sequence, and subse-
quently the RL wheel repeats the cycle.
7) Read values indicated on the brake tester and
check if the fluctuation of the values between de-
compression and compression meets specifica-
tion.
8) After the inspection, depress the brake pedal
and check that it is not abnormally hard, and tight-
ness is normal.
3. CHECKING THE HYDRAULIC UNIT VDC
OPERATION USING A 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 a pressure gauge used for the
measuring transmission oil pressure, as the
piston seal may expand and deform.
NOTE:
Wrap sealing tape around the pressure gauge.
4) Bleed air from the pressure gauge.
5) Perform VDC sequence control.
