ABS SYSTEM
Pressure Decreases in the Circuit when ABS is Operating ▶
Pressure Increases 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.
As the wheel speed increases, the inlet valve opens and the wheel’s pressure increases
due to 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.

4. OVERVIEW
The power steering system consists of pump, oil reservoir, rack and pinion gear. The power
steering pump is a vane type and delivers hydraulic pressure to operate the power steering
system. The pressure relief valve in pump controls the discharging pressure.
The rotary valve in rack and pinion gear directs the oil from the power steering pump to one
side of rack piston.
The integrated rack piston converts the hydraulic pressure to linear movement.
The operating force of rack moves the wheels through tie rod, tie rod end and steering knuckle.
Even though the hydraulic pressure cannot be generated, a driver can steer the vehicle without
power assist but it needs very high steering force.
In this case, the operating force of steering wheel is conveyed to pinion, and the movement o
f
pinion moves the rack through pinion gear combined to rack gear.

2. POWER STEERING GEAR BOX ASSEMBLY
The power steering gear consists of power cylinder and control valve.
The power cylinder has cylinder, piston and piston rod. The control valve directs the oil to one
end face of the piston to enhance the steering force.
The control valve controls the directions and operations of power cylinder.
Additionally, the safety check valve is installed so that the system can be operated manually
when the system is defective.

3. POWER STEERING PUMP
The vane type pump that is connected to engine by belt is used for the power steering system.
This pump generates and controls a proper hydraulic pressure and flows by using the flow
control valve and pressure relief valve.
The flow control valve regulates the excessive amount of discharging oil. When the steering
wheel is stationary or the oil circuit is blocked, the pressure relief valve returns the ove
r
pressurized oil to the oil reservoir.
4. OIL RESERVOIR
The oil reservoir sends the oil to the power steering pump and receives the oil from the power
steering gear.
The oil level in the reservoir depends on the steering wheel positions. therefore, measure the oil
level when the steering wheel is positioned at straight ahead direction (neutral).

AIR BAG SYSTEM
6) Contact Coil
The contact coil is installed between the steering wheel and the steering column and contains a
coil that enables to contact electrically between the airbag wiring harness, the driver airbag
module and the horn switch.
Turning the steering wheel more than three and onequarter turns may damage the clock
spring. The contact coil should never be disassembled and must be replaced if the airbag
have been deployed. -
Turn the label of the clock spring clockwise to lock and turn the label of the clock spring
counterclockwise approximately 2.9 ± 0.2 turns to the neutral positions with the front
wheels ahead.
Align the pointed marks “43”. -
7) Accelometer Sensor
The accelerometer sensor electronically represents the acceleration or deceleration of the
vehicle during a frontal impact.
In this electronic representation, the electrical signal is proportional to the acceleration o
r
deceleration of the vehicle.
8) Safety Sensor
The safety sensor is safety device made up of a dualcontact, electro-mechanical switch that:
Acts independently of the electronic components.
Connects the acceleration sensor in series in order to make up for the weak points in the
current electronic sensor. 1.

11) Wiring Harness Connectors
If the sensing and diagnostic module (SDM) electrical connector is not attached properly, a built
in shorting bar will connect the wire from airbag warning lamp with the SDM ground wire. This
turns on the AIRBAG indicator.
To prevent deployment during servicing, additional shorting bars are located in following
locations:
Driver airbag module connector
Passenger airbag module connector
Driver and passenger side airbag module connector
SDM wiring harness connector
Contact coil connector to airbag wiring harness ·
·
·
·
·
The shorting bar is only a backup safety device. Always disable the supplemental restraints
system (SRS) before beginning any service procedure.
12) Belt Pretensioner
The belt pretensioner enables to retract the driver and the passenger seat belt webbing to
reduce any personal impact when accounted a frontal collision.
