Appearance and Characteristics of the Airbag Indicator Lights

Airbag Indicator Light

Depending on the car and model series, the airbag warning light may look different, and there may be other types for other airbag systems. 

Here are the most common of these types:

  • Standard airbag warning light: usually shows a pictogram of an airbag or a male with an airbag on his lap. If this is lit, there is a problem with the airbag system.
  • Passenger Airbag Warning Light: This light indicates a problem with the passenger airbag. Sometimes it can also indicate whether the passenger airbag is activated or deactivated.

Remember, if an airbag warning light is on continuously or flashing, it’s a sure sign that there’s trouble.

Common Reasons for the Airbag Indicator Light Coming on.

This section will look at the most common causes for the airbag warning light to come on. 

1. Defective airbag modules or sensors

A common cause of an illuminated Airbag Indicator Light is faulty airbag modules or sensors. 

The warning light may go off if a sensor goes haywire or an airbag module malfunctions. 

In such cases, you should have the airbag system checked by a garage!

2. The airbag control unit is acting up

Sometimes the problem lies with the airbag control unit. 

This small device is the brain of the airbag system and ensures that everything runs smoothly and that the airbags are triggered in an accident. 

If there is a problem with the control unit, the warning light may come on. 

A defective control unit can be easily and quickly replaced with a new one or sometimes reset. 

Here applies: Be sure to have it done by a professional.

3. Defective or loose connections

Defective or loose connections can also be blamed for the Airbag Indicator Light lighting up. 

To explain briefly: In your vehicle, many hundreds of meters of cables and associated connectors ensure the airbags function correctly. 

It happens from time to time that these connections become loose or corroded. 

The consequence: the warning light is activated. 

A thorough inspection of the wiring and plug connections is then called for!

4. Expired airbags? Yes, that’s a fact!

Did you know that airbags have an expiration date? 

The lifespan of airbags is usually in the range of about 10 to 15 years. After that, their function can no longer be guaranteed. 

If your airbags are expired, that can also cause the Airbag Indicator Light to light up. 

A look at the manual can help!

What you can do: Save time at a repair shop. 

This brings us to the next question: When should I visit a specialist for an airbag warning light? 

When Should I see a Specialist?

You can only avoid visiting a specialist workshop if it’s a short-term malfunction and the airbag warning light is activated longer. 

There are, therefore, two scenarios in particular:

Although there is little you can do on your own in the event of a problem, numerous preventive measures can keep your car’s airbag system running smoothly. 

In this way, you can protect yourself from the problems already described.

1. Regular maintenance of the vehicle

Regular vehicle maintenance is one of the most important preventive measures to avoid airbag problems. 

Inspecting the airbags, sensors, and connections can work wonders.

2. Keep an eye on airbag expiration dates

3. Be careful when installing accessories and electronic devices

It would help to be especially careful when installing accessories or electronic devices.
