How to Check if Air bag Warning Light On

How to check if airbag warning light on always.
What may be the cause of airbag indicator light on always.
Model: Hyundai Azera
Year Model: 2009
Fuel: Gasoline
Displacement: 3300cc
1) Condition

1. Esp/Airbag warning light is “On” when driving.

2) Cause

1. Internal fault of steering angle sensor.

3) Diagnosis

1. Scan tool check.
   = Trouble code ( C1260 – Steering Angle Sensor Signal.
   =General Description.
   =The steering angle sensor (SAS) joined to the multifunction switch and using a CAN communication.The SAS is composed of main gear,serve gear 1 and serve gear 2 to determine the turning direction. If main gear is rotated according to the rotation of the steering wheel gear serve 1 serve gear 2, which is contact with main gear, will be rotated.
   =The HECU detects the absolute angle by using magnetic MR effects and the different gear ratio of each serve gear and then send to the  CAN communication line.
   =The HECU detects the steering wheel’s operating wheel speed and operating wheel angle by using absolute angle , and this signal is used as input signal of anti-roll control.
   = If the SAS signal is different from calculated value by Yaw-rate sensor and wheel speed sensor,mechanically impossible  SAS signal is detected , there is a different between SAS signal and driving condition of the vehicle calculated from the Yaw-rate sensor and later G-sensor , a failure is detected.
2. Possible cause.Short of steering angle sensor,Faulty steering angle sensor,Faulty HECU.
3. Current data monitoring
   Steering angle sensor ( 0 ) degrees always.
4. Replace Steering angle sensor. then calibrate with GDS or G-Scan.
   =the problem disappeared.

4) Repair Guides

• Replace with new Steering angle sensor.

“How to Test the Electronic Voltage Regulator”

This the continuation of Regulated Voltage Test Study 4.
TEST:

1. Turn On the Ignition switch and check to see the voltage indicates the following value.
   
   Voltage: Battery Voltage.
   
   If reads 0V, there is an open circuit in the wire between the alternator “B” terminal and the battery and the battery (-) terminal.
2. Start the engine. keeps all light and accessories off.
3. Run the engine at the speed of about 2,500 rpm and read the voltmeter when the alternator output current drops to 10A or less.

RESULT:

1. If the voltmeter reading agrees with the value listed  in the regulating voltage table below, the voltage regulator is functioning correctly. If the reading is other than the standard value, the voltage regulator or alternator is faulty.
   
   REGULATING VOLTAGE TABLE:
   
   Voltage regulator ambient                              Regulating Voltage
       temperature *c(*F)

Hyundai Grandeur (XG) 2004/Intermittent Engine Stalling

Troubleshooting your engine - that's a large arena. After all, most of your car is engine. Or at least the part that you need. Your car's engine is made up of many systems that all have to work together in order to make your car run the way it should. The best way to troubleshoot your engine is to observe the problem and the symptoms, then trace those symptoms to the most likely repairs. We can help you do just that.
Observation is the key to engine troubleshooting. You know your car better than anyone. This means that if it's making a sound or a smell that's not normal you will most likely notice something's awry. Many times a strange smell or sound is no big deal, but when you know that something is wrong these clues can be the key to prope3r troubleshooting.
The following areas will come up during troubleshooting analysis. Follow the trail and you will find troubleshooting salvation, or at least a shorter day of troubleshooting. these is a field case trouble shooting from Hyundai Grandeur.
