Causes / consequences flashing or illuminating airbag indicator light / SRS light

The most important information at a glance: There are many safety systems in modern vehicles that protect the occupants in the event of an accident. The so-called "Supplemental Restraint System", Also known as SRS for short, translates as"complementary restraint system". This system includes several airbags, seat belt tensioners and many sensors. If the airbag or SRS indicator light appears while driving or with the engine running yellow flashes or lights up, this is an indication of a problem with the restraint system of the vehicle. In the event of an accident, the restraint system with the airbags only functions to a limited extent or not at all, which represents a major safety risk. For this reason, you should get a Workshop be sought out. The vehicle's fault memory can be read out there, the cause can be determined and then rectified.

You will now find out what possible causes and what you need to be aware of.

Causes / consequences flashing or illuminating airbag indicator light / SRS lightThe Airbag indicator light / SRS indicator light shows a seated driver with an airbag (circle) and looks similar in all vehicles. When it is active, it usually glows amber. On some other vehicles, it can also light up red. Various sensors and components are continuously monitored in the airbag control unit.

For example Crash sensors, perhaps Pre-crash sensors, pretensioners respectively Seat belt buckles, Seat occupancy mats and the airbags. If a fault occurs in one of the components or sensors, the light for the airbag or the SRS is activated to warn the driver of the vehicle and have the problem rectified. The following causes can cause an activated light:

  • A defective seat belt buckle.
  • The wiring is defective or loosened.
  • The slip ring on the steering wheel is defective.
  • The seat occupancy mat is defective.
  • The crash sensor is defective.
  • The airbag control unit is defective.
  • The airbag is defective.
  • The belt tensioner is defective.

For safety reasons, work on the airbags is permitted only by trained professionals be made. You should therefore definitely go to a workshop to have the error memory read out there. Often the cause can be found in this way. When the ignition is switched on in a vehicle, the airbag indicator light must light up briefly and then light up go out again. This shows that the system is working properly. But if they do after starting the engine and while driving remains lit, you should go to a workshop as soon as possible.

If the airbag control unit detects a problem and the warning light is activated, the restraint system will only function to a limited extent. In the event of an accident, this represents a high safety risk for the occupants. You should always have a workshop determine the cause and have it rectified professionally. Do not get involved in false compromises or "YouTube handicraft solutions" in which something is bridged or tricked. This can be life-threatening for you and the other inmates. Repairs to the airbag may only be carried out by specialists. If the airbag indicator lamp lights up continuously after the engine has been started, the general inspection cannot be passed either.
