8.Connect the battery negative cable.
9. After installing the airbag, confirm proper system operation:
a. Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.
b. Make sure horn button works.
INSPECTION
Driver Airbag (DAB)
If any improper parts are found during the following inspection, replace the airbag module with a new one.
Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified
tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious
personal injury.
1. Check pad cover for dents, cracks or deformities.
2. Check the airbag module for denting, cracking or deformation.
3. Check hooks and connectors for damage, terminals for deformities, and harness for binds.

description of ESP
Optimum driving safety now has a name : ESP, the Electronic Stability Control.
ESP recognizes critical driving conditions, such as panic reactions in dangerous situations, and stabilizes the vehicle
by wheel- individual braking and engine control intervention with no needfor actuating the brake or the gas pedal.
ESP adds a further function known as Active Yaw Control (AYC) to the ABS, TCS, EBD and ESP functions. Whereas
the ABS/TCS function controls wheel slip during braking and acceleration and, thus, mainly intervenes in the
longitudinal dynamics of the vehicle, active yaw control stabilizes the vehicle about its vertical axis.
This is achieved by wheel individual brake intervention and adaptation of the momentary engine torque with no need
for any action to be taken by the driver.
ESC essentially consists of three assemblies : the sensors, the electronic control unit and the actuators.
Of course, the stability control feature works under all driving and operating conditions. Under certain driving
conditions, the ABS/TCS function can be activated simultaneously with the ESP function in response to a command
by the driver.
In the event of a failure of the stability control function, the basic safety function, ABS, is still maintained.
DESCRIPTION OF ESP CONTROL
ESP system includes ABS/EBD, TCS and AYC (Active yaw control) function.
ABS/EBD function : The ECU changes the active sensor signal (current shift) coming from the four wheel sensors to
the square waveform.By using the input of above signals, the ECU calculates the vehicle speed and the acceleration
& deceleration of the four wheels.And, the ECU judges whether the ABS/EBD should be actuated or not.
TCS function prevents the wheel slip of drive direction by adding the brake pressure and engine torque reduction via
CAN communication.TCS function uses the wheel speed sensor signal to determine the wheel slip as far as ABS
function.
AYC function prevents unstable maneuver of the vehicle. To determine the vehicle maneuver, AYC function uses the
maneuver sensor signals(Yaw Rate Sensor, Lateral Acceleration Sensor, Steering Wheel Angle Sensor).If vehicle
maneuver is unstable (Over Steer or Under Steer), AYC function applies the brake pressure on certain wheel, and
send engine torque reduction signal by CAN.
After the key - on, the ECU continually diagnoses the system failure. (self- diagnosis)If the system failure is detected,
the ECU informs driver of the system failure through the BRAKE/ABS/ESP warning lamp. (fail- safe warning)

2.STEP 2
It analyzes the movement of the ESP vehicle.
3. STEP 3
he HECU calculates the required strategy, then actuates the appropriate valves and sents torque control requests
via CAN to maintain vehicle stability.

DESCRIPTION
GENERAL DATA
The steering angle speed sensor detects the angle of the steering wheel in order to which direction a user chooses.
MEASUREING PRINCIPLE
A non contact, analog angle sensor carrying out absolute measuring by the use of the Anisotropic - Magneto- Resistive
effect (AMR).Measuring of the absolute angle by means of a toothed measuring gear with magnetic properties in
combination with different ratios. Corresponding AMR elements that change their electrical resistance according to the
magnetic field direction detect the angle position of the measuring gears.A micro- controller decodes the measured
voltage signals after A/D converting with the help of a mathematical function. Output of the digital angle value and
velocity via CAN- interface.
