How To Reset an Airbag Light in Simple Six Steps

The airbag system in a car is a critical component in preventing accidents. An airbag light serves as a safety alert system, indicating issues with the airbag system. It illuminates to signal that there is a problem with the airbag, which could prevent it from deploying in the event of a collision.

An airbag control unit is a module used to detect and evaluate the level of an accident. It uses the information to make the right decision whether to deploy the system or not.

So, the unit is responsible for controlling the airbag’s deployment, storing the crash data, and also exchanging the data with the car’s engine. If your airbag control unit is faulty, the airbags of the car may not react in a collision.

Resetting an airbag light is important as it ensures your car’s safety system is in good working condition. However, all issues causing the airbag light to illuminate should be addressed before resetting.

Now, let’s go deep to explain how to reset an airbag light in six simple steps!

How to Reset an Airbag Light

You can reset your airbag light by simply turning the ignition light on and off, taking a quick test drive, checking all the airbag switches, checking the seat belts to see if they are properly working, confirming if the passenger weight sensor is on, and finally using an OBD II scanner to reset the code.

1. Turn the ignition on and off.

First of all, turn on the ignition switch, then check if the airbag light illuminates. The light will come on after seven seconds and stays on until it automatically turns off. Then, you turn off the ignition switch right away and wait for three seconds.

2. Take a quick test drive.

Restart your ignition and take a quick test drive. Check the electrical system under the driver’s and passenger’s seats before restarting your car. Inspect the connector plug for any corrosion or loose wires. If none, spray an electronic cleaner onto the connector plugs. To see if the light shuts off automatically.

3. Locate and check the passenger airbag switch.

You should also check the passenger seat airbag on and off button if you are to turn off the airbag light. Although it is only available in some vehicles, check; someone might have accidentally turned it off.

4. Check the seat belts to ensure that they are working properly.

Your airbag light can come on because of a bad seat belt. Plug each seat belt in individually to ensure that it clicks before pressing the button to release it while your car is running.

5. Check if the passenger weight sensor is on.

Most cars have a passenger weight sensor that is highly sensitive. The issue with these particular vehicles is that placing a heavy box or container on the passenger seat will trigger the sensors.

6. Use an OBD-II scanner to reset the codes.

To reset your airbag light, you can buy a scanner with SRS capabilities if you know how to use it. Just be aware that not all OBD-II tools can automatically reset the airbag light.

It’s wise to do some research before buying an OBD-II scanner with the features you require. Learn a Quick Fix on How to Reset an Airbag Light with the Video Below:
