What does a Kia airbag light mean?

what does it mean when kia airbag light stays on

If your Kia airbag light comes on, it means that the Supplemental Restraint System (SRS) has detected a problem with one of the airbags, there is a faulty airbag sensor, or the battery voltage is too low.

The airbags may not deploy if you get in an accident.

To diagnose Kia airbag light, you can't use a generic OBD-II scanner. You need an OBD-II scanner for the airbag system

Common Kia Airbag Problems

Your Kia airbag light may come on for several reasons. The most common problems that trigger Kia airbag lights are: 

  • Passenger occupancy sensor (front passenger seat)
  • The airbag module has stored codes.
  • Side crash sensor faulty
  • Previous accident
  • Impact sensors damaged
  • Faulty Clockspring
  • Low battery voltage

The airbag / SRS module consists of multiple components, and any of them could malfunction. Without reading the codes, it is hard to know the root of the problem.

1. Passenger Seat Mat

Kia cars are equipped with a passenger detection system. It includes a sensor in the passenger seat (known as Occupant Detection Sensor or OBS sensor) that can detect a passenger in the seat.

The reason for this system is that if a child or no one is sitting in the passenger seat and you get involved in an accident, the passenger airbag will not deploy.

The passenger seat mat is a common problem that triggers Kia airbag light. Typically it will trigger fault codes B1448, B1447, B1448, B1764, and B1767.

First, check the electrical connection under the passenger seat and make sure nothing is loose or disconnected.

If the occupant detection sensor is defective, it needs to be replaced. The first thing you need to do is call your Kia dealer and check if a recall is open for your vehicle. 

2. Low Battery Voltage

You may trigger the airbag / SRS warning :

  • after you replace the battery
  • if you have had a dead battery
  • jump-started a Kia with a dead battery

The vehicle detects low voltage in such cases, and the airbag control module triggers the airbag light.

To avoid such problems, you should always turn off the ignition and remove the key when replacing the battery. Always remove the key from the ignition if you check fuses, especially if you remove the airbag fuse.

3. Car Accident

If any airbags were deployed because your car was in an accident, crash data would have been stored in the Kia airbag module.

Crash data stored in the airbag module can not be cleared with most airbag scanners. They need to be cleared by the dealer or a specialized technician. Dealers will most likely recommend replacing the airbag module. 

If you have the dealer diagnose the vehicle in most cases, they will recommend replacing the module. It is possible, however, to get your existing airbag module reset. Instead of buying a new module, consider having a repair center reset your existing module. You can find such a service even online. For example, see Kia Airbag SRS RCM SDM ACM Module Reset on eBay Service.

These services will clear both hard and soft codes from the airbag module. Once you receive your unit back, you will not need to do any additional programming or go back to the dealer for programming.

How to Reset Kia Airbag Light

To find out why your Kia airbag light is on, you will need to read the airbag module's fault codes. Reading codes from the airbag module is very easy.

For this procedure, you will need an Airbag Scanner that works on Kia vehicles. 

  1. Locate the diagnostic port under the dashboard on the driver's side. kia airbag diagnostic port


  2. Plugin your airbag scanner and turn on the ignition. Do not start the engine.diagnose kia airbag light, turn on ignition
  3. Select your Kia, select your model, Sorento, Sedona, Rio, Optima, Telluride, Soul Forte, etc. 
  4. From the main menu, select the Airbag / SRS module.
  5. Select Read DTC or Read Fault codes from the menu. Ensure all the codes are in stored status. If any codes are present or current, you need to fix that to change the stored status. 
  6. Once the fault codes show as stored, go back and select Clear Fault codes. 

Airbag Recall

In February 2016, Kia issued a service bulletin, which is given to all Kia dealerships service departments, providing information on replacing a weight sensor mat located in the front passenger seat.

Kia extended the warranty coverage for this repair upon releasing this bulletin to 15 years / unlimited mileage, starting from the date of the first service. Coverage will be provided for its replacement, provided that the condition is not caused by external damage to the sensor mat.

Kia Rio, Optima, Sedona, Forte owners have complained about the airbag light coming on either intermittently, blinking, or illuminating and staying on while driving.


It is normal, for a passenger airbag to turn off if there is no passenger seated at the front passenger seat or if a child is placed on the seat. 

If the SRS system in your Kia is not working properly, the airbag warning light will illuminate your instrument cluster. When there is a problem with the passenger detection system, the PASSENGER AIR BAG "OFF" light will not turn on, and the passenger airbag may or may deploy regardless if there is a passenger in the front seat.
