How To Fix Mercedes-Benz Airbag Warning Light

Airbags are one of the most essential components of any modern automobile, with the National Highway Traffic Safety Administration (NHTSA) estimating that frontal airbags had saved 50,457 precious lives between 2017 and 2020. In extension to this, the importance of the airbag warning light becomes very apparent, due to its role of indicating when something’s wrong with your car’s SRS system. In this article, we give you a step-by-step guide on fixing your Mercedes-Benz Airbag warning light.

Is It Time to Fix Your Airbag Warning Light?

If your Mercedes-Benz vehicle’s airbag warning light stays on, there’s most likely a problem with the airbags or another component of your car’s Supplemental Restraint System (SRS) system, such as your airbag inflator or impact sensors. Some of the most common issues that can lead to your Mercedes-Benz airbag warning light coming on are:

  • Drained airbag backup battery
  • Defective impact sensors
  • Damaged airbag clock spring
  • Water-damaged airbag module

Though it’s unlikely that these problems will cause your airbags to randomly deploy, the main concern with your airbag warning light remaining on is the possibility of your airbags failing to deploy during a crucial moment such as an accident. Hence, while your call will still run even with the airbag warning light on, all drivers should endeavor to diagnose and resolve the issue as soon as possible before getting back on the road safely.

Fixing Your Mercedes-Benz Airbag Warning Light

Unfortunately, even after you diagnose and address the issue, your airbag warning light won’t reset on its own. Hence, you’ll need to reset your Mercedes-Benz airbag warning light manually using an ECU programmer. Below is a step-by-step guide on how to reset your Mercedes-Benz airbag warning light.

  • Locate the OBD port in your vehicle, which is usually placed on the driver’s side, beneath the steering wheel.
  • Connect your ECU programmer to the OBD port.
  • Turn the ECU programmer on and on the menu, select the SRS system, which should be listed as an option on your ECU programmer’s main menu.
  • Clear the error codes in your SRS system, using the “clear codes” option. This option will erase all the error codes from your SRS system, and thus, turn off your SRS light.

While there are many “read and reset” scanners available on the market, most experts recommend visiting your local certified Mercedes-Benz technicians instead, which will save you more time and money when addressing your airbag-related problems as a whole.

Airbag Maintenance Tips

Below are some best practices to follow to ensure that your airbags are kept in good condition for longer, allowing you to stay on the road for longer as well:

  • Get your airbags checked at least once every four years to ensure that they’re functioning perfectly.
  • After an accident, rather than having your airbag fixed or repacked, it’s safer to replace it entirely.
