If your Mercedes-Benz was involved in an accident, you wouldn’t be able to clear the fault codes even if you have Star diagnostics or a professional airbag scanner.

First, you need to replace all the deployed airbags, damaged sensors, and seat belts. Next, you will have to install a new airbag module or have a professional reset your airbag module on eBay. You can remove your airbag module, ship it to a professional to clear the hard codes, and reinstall it. No coding is needed.

Why can’t I reset the Mercedes-Benz airbag light?

Can't reset Mercedes airbag light

If your Mercedes-Benz was involved in an accident, two things need to happen for you to reset the SRS system and have a working airbag system.

  1. First, you need to replace all deployed airbags. Replace any damaged SRS crash sensors. When you read the codes with an SRS scanner, you will get fault codes for each damaged component. You may need to replace the seat belts, as well.
  2. Second, you need to either precise crash data from the airbag module or replace the airbag module. If you replace all the deployed airbags and damaged SRS components, the codes in the airbag module change from CURRENT to STORED, but you can’t clear them because they are from a crash event. You can’t install a used airbag module from another car even if it has the same part number. You need a new SRS module that can be programmed for your car. A less expensive solution is to remove your old SRS module and ship it to professionals who can clear the crash data.

Where is the Mercedes airbag module located?
