In a car, what does SRS stand for? Everything you need to know about the topic

Do you know why airbags in certain cars deploy to protect the driver and front-seat passenger in the event of a collision? Do you know why some cars crash or collide, yet the airbags in the front seat fail to deploy to protect the driver and passenger? Many car owners, particularly new car owners, have pondered these questions.

The SRS mechanism in the car is the basic cause for the two contrasting experiences described above. Now you might be wondering, "What does SRS imply in a car?"

This page contains enough information to help you understand the meaning of the term "SRS," its function in a car, and how to resolve the problem when the SRS light automatically goes on and refuses to turn off.

Were also aware that if the SRS/airbag light is on in your dashboard, this is also an MOT failure but most importantly a risk of you and your passenger’s safety. Check MOT history online to see that there is not a pattern for failure on previous MOT tests and make your car mechanic aware of this.

In a car, what does SRS stand for? 

SRS stands for Supplemental Restraint System. The Supplemental Restraint System (SRS) is a technological component in your automobile that controls the airbags and automated seatbelt restraints. The restraint system is passive since it does not require any activity on your part to operate. It is self-contained and serves to ensure the driver and passenger's safety. Go through the MOT certificate and check MOT expiry date to have the defective airbag issue resolved before the next MOT test.

The Supplemental Restraint System (SRS) is a computerised restraint system. The computer communicates with a specialised network of sensors, which aid in the detection of various actions while your car is in motion. The system monitors deceleration, braking, and collision position and has been programmed as an artificially intelligent component. It can also tell whether there is a passenger in the vehicle's front seat.

The SRS system sends a message to the car's Airbag Control Unit after automatically determining the activities described in the preceding paragraph. This allows the car's Airbag Control Unit to determine which airbag to trigger and which seatbelts to tighten. All of these functions are carried out automatically, so you don't have to do anything.

However, assuming that the SRS system would continue to work correctly throughout the vehicle's lifetime is not adequate. Every component in your car was created with a particular life expectancy in mind, which typically does not surpass the life expectancy of the vehicle. However, certain parts break down when you least expect it.

Meanwhile, a problem with your car's airbag may cause the SRS light to illuminate; it may also illuminate owing to a faulty seatbelt buckle, a loose wire, or a challenge presented by your car's Engine Control Unit (ECU). If your SRS light illuminates but does not turn off, it indicates a potential concern since the airbags will not deploy if a collision happens.

As a result, if your vehicle's SRS light suddenly illuminates and remains on, the next part of this article offers a solution. You can also complete a MOT history check to see if this was also an issue in the past.

How to Repair an SRS Light

If your car's SRS light goes on automatically and refuses to turn off, the steps below will teach you how to fix it.

Make use of an OBD2 scanner. The OBD2 scanner is a gadget that can read the condition of a car and determine the exact problems it is having in a matter of seconds. Code readers and scan tools are included with the OBD2 scanner. 

The scan tools are more costly since they give deeper insight into issues and improve troubleshooting. In the meanwhile, you should try to find a scanner that can read and reset your car's SRS system. Follow these easy instructions to use the OBD2 scanner:

Step 1: Turn off your car and attach the scanner to it using the data link connector found beneath the control panel. After you plug in the scanner, it will begin to work.

Step 2: After you turn on your car, wait for the OBD2 scanner to start up. If it doesn't start up on its own, hit the power button to start the process.

Step 3: Once the scanner is ready, it will prompt you to enter some information about your vehicle. Input information such as the brand, model, and engine of your car, if applicable. After that, the system will scan the vehicle's diagnostic system and evaluate it.

Step 4: When the scan is finished, the scanner will display an error message or a series of codes, take note of them.

Step 5: Look up the meaning of each code in the OBD2 scanner handbook to help you discover a solution. If you can't find the answers to the code in the manual due to the lack of information, you can look for the solution on the internet. Be careful to look for codes specific to your vehicle's make and model.

Finally, after you've found the answer in the handbook or on the internet, put it into practise right away. The reason the SRS light is on is usually traceable to one of your car's components. As a result, the scanner offers precise information on the exact component, allowing you to correct it with a simple reset. If you realise that on the MOT history the SRS/airbag light has been a culprit regularly, then a simple reset may not work.

Seek the advice of a qualified car technician.

Typically, there is a problem with a component that links to the SRS system that the scanner cannot fix right away. As a result, a mechanic would be required to fix that exact component before the SRS light would turn off.

It's also a good idea to consult an auto mechanic after utilising the OBD2 scanner to turn off the SRS light because the light may turn off momentarily while the real problem remains. So, even if you think the situation is solved, tragedy might still be lurking around the corner. As a result, you must ensure that the problem is entirely resolved, rather than concluding that the scanner assisted you in turning off the SRS light.

Frequently Asked Questions (FAQ’s)

Is a SRS/airbag warning light a MOT failure?

Yes, it is correct. When your vehicle's SRS warning light is illuminated, it almost always means a MOT failure. The Ministry of Transport is abbreviated as MOT. An MOT is a yearly vehicle inspection that determines the vehicle's legal roadworthiness. They inspect cars to verify that they are safe and that emissions and environmental requirements are met. The engine light on the car is likewise not excluded.

If the SRS light is on, will airbags go off?

No, the airbags aren't going to go off. In the event of an unexpected accident, the Supplemental Restraint System handles both the automated seatbelt restraint and the airbag activation for release. If the SRS warning light is illuminated, it means the car isn't completely safe to drive, since the airbag on the driver's side or the passenger's side may not be activated.

Is it possible to drive with the SRS light on?

Yes, you may drive with the SRS light on because it has no effect on the smooth operation of your vehicle. It is, however, dangerous to do so. The Supplemental Restraint System is responsible for controlling the car's airbag and automated seatbelt restraint.

As a result, if you drive with the SRS light on, there's a chance the car's airbag won't deploy in the event of an accident, putting your and your passengers' lives in danger.

Furthermore, if you are involved in an accident, you may be unable to file an insurance claim since the car's black box recorder, which is part of the SRS, is responsible for displaying the data that your car's airbags warning light has been on continuously. Nonetheless, you failed to see the sign and repair it before the collision.

As a result, driving with your car's SRS light on is irresponsible on your part. If you ever have this problem, see a skilled car mechanic to get it fixed.

Final Thoughts

You may no longer need to wonder, "What does SRS imply in a car?" after reading this article because pertinent information has been provided on the issue.

As a car owner, ensuring that your vehicle and all of its components are in good working order before hitting the road should be a top concern. Always Be Careful is an abbreviation that stands for Always Be Careful.

As a result, if your car's SRS light comes on and doesn't go out for a time, seek a skilled auto repair to evaluate the problem and suggest a remedy before doing anything else.
