ABS CONTROL MODULE AND HYDRAULIC CONTROL UNIT (ABSCM&H/U)
4) Using cable clip, secure ABSCM&H/U harness
to bracket.
5) Connect connector to ABSCM&H/U.
CAUTION:
• Be sure to remove all foreign matter from in-
side the connector before connecting.
• Ensure that the ABSCM&H/U connector is se-
curely locked.
6) Install air intake duct.
7) Connect ground cable to battery.
8) Bleed air from the brake system.
C: INSPECTION
1) Check connected and fixed condition of connec-
tor.
2) Check specifications of the mark with AB-
SCM&H/U.

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.
