Electronic system service precautions

Take care to avoid electronic brake control module (HECU)
circuit overloading. In testing for opens or shorts, do not
ground or apply voltage to any circuit unless instructed to
do so by the diagnostic procedure.

Test circuits only with a high-impedance multi-meter. Never
remove or apply power to any control module with the igni-
tion switch in the ON position. Always turn the ignition to
the OFF position before removing or connecting battery
cables, fuses or connectors.

General service precautions

Disconnect the HECU connector before performing any
vehicle welding work using an electric arc welder.

Do not attempt to disassemble any component designated
as nonserviceable. The hydraulic modulator and the HECU
can be seperated. (There is however no access to repair
the each components.)

Bleeding system

Replacement modulators are shipped already filled and
bled. In normal procedures requiring removal of the
modulator, such as to replace the HECU, air will not enter
the modulator, and normal bleeding will be all that is
needed.

If air enters the hydraulic modulator, or if an unfilled modu-
lator is installed, use the brake bleeding program in the
scan tool to bleed the modulator. Manual bleeding of the
hydraulic modulator is not possible.

ON-VEHICLE SERVICE

Service Precautions

 [Notice]

Brake Fluid may irritate eyes and skin. In case of contact,
take the following actions:

Eye contact - rinse thoroughly with water.

Skin contact - wash with soap and water.

Ingestion - consult a physician immediately.

 [Notice]

Avoid spilling brake fluid on any the vehicle’s painted
surfaces, wiring, cables or electrical connectors. Brake
fluid will damage paint and electrical connections. If
any fluid is spilled on the vehicle, flush the area with
water to lessen the damage.

 [Notice]

Use only DOT-3 equivalent hydraulic brake fluid. The use
of DOT-5 (silicone) brake fluid is not recommended.
Reduced brake performance or durability may result.

 [Notice]

To help avoid personal injury due to poor braking. DO
NOT Tap into the vehicle’s brake system to operate a
trailer brake system.

 [Notice]

When fasteners are removed, always reinstall them at the
same location from which they were removed. If a fastener
needs to be replaced, use the correct part number fastener
for is not available, a fastener of equal size and strength
(or stronger) may be used. Fasteners that are not reused,
and those requiring thread-locking compound will be
called out. The correct torque values must be used when
installing fasteners that require them. If the above
procedures are not followed, parts or system damage
could result.

2. COMPONENTS AND LOCATION

Newly introduced ABS has a different shape of integrated hydraulic modulator and HECU (Hydraulic and Electronic
Control Unit) compared to existing ABS. And, the wheel speed sensor uses different method to detect wheel speed. The
basic function of the ABS that maintains the vehicle stability by controlling the steerability of the vehicle when braking
has not been changed.
