SRS, commonly found in cars, stands for Supplemental Restraint System, including airbags. Exploring its significance in vehicle safety is our aim in this article. We’ll discuss about the history, components, and operation of SRS. We will also discuss why is it so important in today’s vehicles.
What does the SRS Light mean?
SRS, short for Supplemental Restraint System, is a crucial safety feature in modern cars, designed to safeguard passengers during collisions, often referred to as the airbag system.
Working of SSR Light in a Car?
When they are deployed, the airbags inflate with gas. This creates a shield between passengers and the car’s interior. This reduces the impact force in high-speed crashes. The SRS maximizes the protection in accidents by teaming up with seatbelts.
SRS was initially developed in the 1970s. But it became a standard in the late 1980s in vehicles. At the start it was limited to the steering wheel and dashboard. Now they are also included in side curtains and the front passenger area.
Besides airbags, the SRS incorporates crash sensors, control units, and deployment modules. These components collaborate to deploy airbags accurately, considering timing, speed, and force, ensuring effective occupant protection. Additionally, sensors detect passenger position and weight, enabling airbags to deploy in a manner that minimizes injury risk.
The SRS features different airbags:
- Frontal for front-end collisions
- Side for lateral impacts
Regular maintenance and timely replacement of SRS components are essential for its effectiveness. Inspect and repair the SRS promptly if the airbag warning light comes on or after a collision.
How to Fix SRS Light?
1. Determine the Issue
To fix the SRS light, you first need to pinpoint the problem. It may be due to issues like a fault in the airbag sensor, damage in the wiring, or a malfunctioning issue. Use an OBD scanner to check the error in the code.
2. Inspect the Seatbelt Tensioner
The work of a seatbelt tensioner is to tighten the seatbelt in case of a collision. If the SRS light is on, it might be a signal showing an issue in the tensioner. Make sure you check the seatbelt and the connections for damage. If the problem is still there, you must immedietly consult a professional mechanic.
3. Check the Airbag Sensors
Malfunctioning airbag sensors often trigger the SRS light. Damage from wear, corrosion, or accidents can impair these sensors. Check for physical damage and clean them if needed. If damaged, replace them to resolve the SRS light.
4. Inspect the Control Module
The SRS control module acts as the airbag system’s brain, receiving signals from sensors and deploying airbags during collisions. A malfunctioning control module triggers the SRS light. Due to its complexity, only a certified mechanic should repair or replace it.
5. Inspect the Wiring
Faulty wiring is another common trigger for the SRS light. Inspect the wiring harness for damage or looseness. Repair corroded or loose connections, but replace damaged wiring. Proper knowledge and tools are necessary for addressing wiring issues.
6. Clear the SRS Light
After addressing the root cause of the SRS light, it’s essential to reset the system. This action deactivates the SRS light, confirming proper system function. Consult the vehicle’s manual for specific steps on resetting the SRS light.
