When the cam pushes the left plunger
during motor operation, the system pressure
is generated in the left cylinder. At this time,
the right plunger is expanded by spring force
and the expanded volume of the right
cylinder draws the brake fluid.
HECU controls the hydraulic valves by
supplying or cutting off the voltage to
solenoid valves depending on the wheel
speed and other information from wheel
speed sensors.
The figure shown in left side is for ESP
ECU. There are two channels for front
wheels and one channel for rear wheels.
Each channel has one inlet and one outlet
valve, therefore,
there are six solenoid valves.
The electrical components are weak to
moisture. To protect ECU, GoreTex-based
plate is used at ECU lower cover. The vent
hall (arrow) allows air to ventilate but does
not allow moisture to penetrate.

AIR CONDITIONING SYSTEM
3. FFF GENERAL INFORMATION
The system is to increase the coolant temperature quickly by firing diesel fuel in the burner that
is installed in engine cooling system when in winter time the ambient temperature and engine
coolant temperature is low. (Option)
FFH System consists of independent fuel lines, fuel pump, coolant circuit, coolant ciculation
pump, electrical glow plug and exhaust system by driver’s intention because FFH system
is automatically.
Operated according to the coolant temperature and the ambient temperature.
FFH system operates up to more than 2 minutes to burn the residual fuel inside the system
when driver stop the engine during its operation. Therefore, a certain period of FFH operation
after stopping the engine is not a malfunction.

4. SENSORS AND ACTUATORS
1) Sun Sensor
It is installed on the upper left end of instrument panel. It is using characteristics that the
amount of current changes according to amount of light on the photosensitive surface. Photo
diode, converts the changes in light intensity into electrical changes, detects the amount of light
coming through windshield and changes it into current and then sends the signal to FATC
controller.
(1) Inspection
Remove the sun sensor and measure the current between terminals under sunlight.
Measure the current again under shade. It is in normal conditions if the measured value is
less than the measured value under sunlight.
Turn the ignition switch to “ON” position.
Measure the voltage to the sun sensor from FATC connector. (approx. 2.5 V under sunlight
and 4.8 V under shade.)
If the voltage value cannot be measured, check the circuit for open. If the measured value is
within the specified range, replace the FATC controller. 1.

4) Inflator
The inflator is a type of the direct gas generated device.
The inflator with initial low pressure provides negative restraint effect regarding passengers
moving and time.
On the contrary, the inflator with initial high pressure allows other components of the airbag
to make a excessive impact resulting in any personal injury.
Thus, the inflator output must be optimized according to the characteristic of the vehicle and
passenger moving.
The discharge gas has no toxicity or inflammability and also it is the important parameter to
control the high temperature for gas firing. ·

5) SDM (Sensing and Diagnostic Module)
The airbag system consists of the module section (driver, passenger and side), seat belt
section and SDM.
The SDM has no user-serviceable parts and monitors the system components continuously.
The SDM also records any faults which are discovered.
The SDM allows the fault codes to be retrieved with a scan tool and illuminates a warning
lamp that alerts the driver to any faults. 1.
2.
3.
The SDM located on floor beneath the floor console assembly. The SDM performs the
following functions:
Impact decision processor function.
Determine the airbag deployment through the impact signal of the accelerometer sensor and
the safety sensor. ·
·
Malfunction detection and recording any faults that are detected.
Monitor the supplemental restrain system electrical components and set a diagnostic trouble
code when malfunction is detected.
Display airbag fault codes Display airbag fault codes and system status information when
connected to a scan tool.
Self-diagnosis function Illuminate the AIRBAG indicator to alert the driver to any fault.
Power supply function Provide a reserve power source to deploy the airbags and
pretensioners if an accident has disabled the normal power source. ·

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.

3) Seat electrical equipment check
Disconnect the seat wiring connector and check if the power is supplied (Refer to the wiring
diagram)
·
1) If the power supply has no problem, remove the seat.
2) Check the motor and wiring if damaged.
3) Connect the battery to the seat connector.
4) Control the seat switch and check the opration.
- Electrical parts are not supplied by a part separately.
