▶DUMP (ESP is working) Mode
The pressure decreases just before the wheel speed drops and the wheels are locked.
The inlet valve closes and the outlet valve opens as in the ABS HECU and the oil is gathered at
the low pressure chamber while no additional oil is being supplied. Then the pump operates to
allow fast oil drainage. The shuttle valve and the separation valve do not operate while
decompression.

▶Pressure Decreases in the Circuit when ABS is Operating
Even when the hydraulic pressure on each circuit is stable, the wheel can be locked as the wheel speed
decreases. This is when the ABS ECU detects the wheel speed and the vehicle speed and gives the
optimized braking without locking the wheels. In order to prevent from hydraulic pressure increases, the
inlet valve is closed and the outlet valve is opened. Also, the oil is sent to the low pressure changer and
the wheel speed increases again. The ABS ECU operates the pump to circulate the oil in the low
pressure chamber to the master cylinder. This may make the driver to feel the brake pedal vibration and
some noises.

the master cylinder pressure. The oil in the low pressure chamber circulates to the wheel by the pump
and the wheel speed decreases as the hydraulic pressure at wheel increases. This operation continues
repetitively until there are no signs that the ECU is locking the wheels. When the ABS hydraulic pressure
control takes place, there may be some vibration and noises at the brake pedal.

Oil Level Check ▶
Check the fluid level on a level ground with the
engine turned off. The fluid level should be
between the MIN and MAX marks on the
reservoir cap gauge.
Place the vehicle on a level ground and start
the engine and let it run at idle speed.
Turn the steering wheel several times so that
the oil temperature reaches to normal
operating level (75~85˚C).
Place the steering wheel at straight ahead
direction.
Check the oil level in the power steering oil
reservoir. Adjust the oil level between MAX
and MIN. A.
B.

Oil Change ▶
If the difference between two measurements
is below 5 mm and the level is between MAX
and MIN level, it's normal. If it is over 5 mm,
bleed air from the system.
Open the power fluid reservoir cap and drain
the fluid completely with oil suction device.
To make it easy, turn the steering wheel to its
both ends several times.
Fill up the specified fluid into fluid reservoir
and bleed air from the steering system. A.

Air Bleeding ▶
The air bleeding should be done after servicing the
power steering system and when the difference
between two measurements (cooled and normal
temperature) is prominent.
Normal AbnormalLift up the vehicle very carefully.
Turn the steering wheel to its both ends
several times and add the oil up to MAX line
in the steering oil reservoir.
Periodically crank the starting motor and turn
the steering wheel to its both ends without
any interruption.
Check the oil level again. If the oil level is
fluctuated, repeat the procedures from step 3
to step 5.
Start the engine.
Turn the steering wheel to its both ends until
any bubble can be found in the steering oil
reservoir.
Perform the test drive and check the steering
wheel for normal operation and noise.
If the oil level abruptly goes up, bleed the air
from the system again. A.
