The dashboards of most vehicles are littered with a wide array of light-up acronyms and symbols. Most of these are pretty self-explanatory. The blinking stick figure with a seatbelt across it tells you to buckle up, for example. Others, like the ABS and SRS lights, are a little more mysterious. What do they mean, exactly?
The SRS stands for Supplemental Restraint System. It includes a series of sensors and an airbag control unit to make sure that your vehicle's safety features (such as the seat belts) function properly in a crash. A lit-up SRS warning light means there is a problem with the system. It can also cause your MOT to fail if it is left on for too long.
There are a few different things that can cause your SRS light to turn on. For starters, it could be a sign that there has been a previous accident in which the airbags did not deploy. The SRS light may also turn on if there is a problem with the airbag clock spring. This coil maintains the connection between electrical equipment on the steering wheel such as the horn and airbag sensor. It may have simply worn out over time.
If your SRS warning light is turning on, it's important to get it checked out as soon as possible. Any problems with your SRS system could put the lives of you and your passengers at risk in an accident. A qualified mechanic will be able to diagnose the problem and fix it before it becomes worse. They will be able to use the SRS computer to produce a trouble code, which can aid in finding out what is wrong with the system. In some cases, the airbags and other SRS components may be covered by an existing recall or extended warranty, which can help to reduce the cost of repairs.
