GENERAL DESCRIPTION
C: CAUTION
•Wear working clothing, including a cap, protec-
tive goggles, and protective shoes during opera-
tion.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust or dirt.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly, and replacement.
•Be careful not to burn your hands, because each
part in the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shopjacks or safetystands at thespecified
points.
•Before disconnecting electrical connectors of
sensors or units, be sure to disconnect ground ca-
ble from battery.

1. CHECKING THE HYDRAULIC UNIT ABS
OPERATION BY PRESSURE GAUGE
1) Lift-up vehicle and remove wheels.
2) Disconnect the air bleeder screws from the FL
and FR caliper bodies.
3) Connect two pressure gauges to the FL and FR
caliper bodies.
CAUTION:
•Pressure gauges used exclusively for brake
fluid must be used.
•Do not employ pressure gauge previously
used for transmission since the piston seal is
expanded which may lead to malfunction of the
brake.
NOTE:
Wrap sealing tape around the pressure gauge.
4) Bleed air from the pressure gauges.
5) Perform ABS sequence control.
<Ref. to ABS-9, ABS Sequence Control.>
6) When the hydraulic unit begins to work, and first
the FL side performs decompression, holding, and
compression, and then the FR side performs de-
compression, holding, 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. Also check if any irregular brake pedal
tightness is felt.
8) Remove pressure gauges from FL and FR cali-
per bodies.
9) Remove air bleeder screws from the RL and RR
caliper bodies.
10) Connect the air bleeder screws to the FL and
FR caliper bodies.
11) Connect two pressure gauges to the RL and
RR caliper bodies.
12) Bleed air from the pressure gauges and the FL
and FR caliper bodies.
13) Perform ABS sequence control.
<Ref. to ABS-9, ABS Sequence Control.>
14) When the hydraulic unit begins to work, at first
the RR side performs decompression, holding, and
compression, and then the RL side performs de-
compression, holding, and compression.
15) Read values indicated on the pressure gauges
and check if they meet the standard value.
16) After checking, remove the pressure gauges
from caliper bodies.

fuse with the FWD connector in the main fuse box
to simulate FWD vehicles.
2) Prepare for operating ABS sequence control.
<Ref. to ABS-9, ABS Sequence Control.>
3) Set the front wheels or rear wheels on the brake
testerand set theselectlever'sposition at“neutral”.
4) Operate the brake tester.
5) Perform ABS sequence control.
<Ref. to ABS-9, ABS Sequence Control.>
6) Hydraulic unit begins to work; and check the fol-
lowing working sequence.
(1) The FL wheel performs decompression,
holding, and compression in sequence, and
subsequently the FR wheel repeats the cycle.
(2) The RR wheel performs decompression,
holding, and compression in sequence, and
subsequently the RL wheel repeats the cycle.
7) Read values indicated on the brake tester and
check if the fluctuation of values, when decom-
pressed and compressed, meet the standard val-
ues.

played as follows:
(1) When using the brake tester, depress brake
pedal with braking force of 981 N (100 kgf, 221
lb).
(2) When using the pressure gauge, depress
brake pedal so as to make the pressure gauge
indicate 3,432 kPa (35 kg/cm2, 498 psi).
