Is the Mercedes SRS light flashing? SRS stands for Supplemental Restraint System, or the SRS or Airbag Warning Light. This could be because the AirBag Control Unit is not programmed correctly. SRS Control Unit is not parameterized or, as some may refer, taught-in. This can cause the blinking of the airbag / SRS light on the instrument cluster. You may have installed an airbag module from another car, or the existing module was programmed but not appropriately finalized. If the VIN doesn’t match or the control unit is not locked, the SRS light will keep flashing after you start the car. There is a high chance that the airbags will not deploy in case of an accident.
In some of the older Mercedes-Benz models, a blinking airbag light could be due to the airbag’s age or loss of connections to the airbag components.
If a technician, an auto mechanic, or yourself were working recently, you might have accessed the AirBag module and unlocked it to perform programming. Your scanner in most cases, your scanner will automatopen unlock the control module. When you are done programming the Air Bag control unit, you must CLOSE or Lock It by performing initial start-up or parameterization.
It’s important to understand that the correct vehicle identification number (VIN) needs to be coded to the Air Bag unit.
