6) Thermo AMP
The thermo AMP outputs the compressor ON or OFF signal to ECU to prevent evaporator from
freezing. The sensing part of the thermistor is the evaporator fin contact type.
Remove the thermo AMP and measure the voltage between terminal No. 1 and 2 on the
connector.
Check whether the output voltages (ON: approx. 12 V, off: 0 V).
If the voltage value is out of the specified value, replace the thermo AMP. If the circuit is in
normal condition, check as below.
Turn the ignition switch to ON position and turn on the air conditioner by pressing the
A/C
button. And measure the voltage between terminal A12 and A11 on the FATC controlle
r
connector. (standard: approx. 12 V)
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.

3. AIRBAG FUNCTION DESCRIPTION
1) Bag (Cushion)
The airbag system performance is influenced on the cushion size, shape and position.
The cushion strength is a important parameter on the impact absorb effect.
Therefore, the control of the airbag performance depends on cushion size, shape, inflato
r
characteristic and vent hole size for the gas discharge.
The cushion’s material and folding function to control the cushion deployment
direction and the performance to protect passenger’s face. ·
·
·
·
2) Airbag Module
The driver airbag module is under the center pad of the steering wheel.
The passenger airbag module is installed in the instrument panel at passenger side.
The driver and passenger side airbag is inside each seat.
3) Module Cover/Housing
It is a type of a container that includes the cushion and the inflator.
The module housing functions to deliver the reaction force between the body structure and
the airbag (The airbag reaction is absorbed generally to the steering wheel or instrument
panel).
The module cover must be considered in a viewpoint of protection between exterior,
internal units and cushion. Also the module cover should be designed not to cause any
personal injury for deployment. ·
·
·
Do not disassemble the airbag module because unintentional deployment of the airbags
resulting from any damage or interference of the module can cause injury. -

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.

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.
