Imagine driving down the road when suddenly your car’s airbag warning light illuminates. It’s a scary situation, and it could mean a serious problem with your car’s safety system. The first thing you might think about is, “How can I figure out what’s wrong?”. Thankfully, a scan tool can help you read the SRS code and diagnose the problem.
What is an SRS Code?
SRS stands for “Supplemental Restraint System,” which is another name for an airbag system. An SRS code is an error code stored in the airbag control module (ACM) that indicates a problem with the system. These codes can be read using a scan tool, which is a device that connects to your car’s diagnostic port and allows you to access and interpret the data stored in the vehicle’s electronic control units.
Why Do You Need a Scan Tool to Read SRS Code?
Importance for Mechanics and DIYers
The importance of using a scan tool to read SRS codes cannot be overstated. Whether you’re a professional mechanic or a DIY enthusiast, having this tool can save you time, money, and potential safety risks. Here’s why:
- Pinpointing the Problem: A scan tool provides a specific error code, which helps narrow down the potential causes of the airbag warning light. It’s much easier to diagnose a problem when you have the right information.
- Avoiding Costly Mistakes: Without a scan tool, you might end up replacing parts unnecessarily. This can be a costly mistake, especially with safety systems like the airbag.
- Ensuring Safety: A malfunctioning airbag system is a serious safety risk. A scan tool allows you to diagnose and repair the problem quickly, ensuring the safety of yourself and your passengers.

Finding the Right Scan Tool to Read SRS Code
There are many scan tools available on the market, but not all of them are created equal. Some are designed for specific car brands or models, while others offer broader compatibility.
What to Consider When Choosing a Scan Tool
- Car Compatibility: Ensure the scan tool is compatible with your car’s make and model. Some tools are designed for European vehicles, while others are made for American or Asian cars.
- Features: Consider the features offered by different scan tools. Some tools can only read basic codes, while others can perform more advanced diagnostics, like clearing codes, live data, and even reprogramming modules.
- Price: The cost of scan tools varies significantly. Decide your budget and choose a tool that fits your needs without breaking the bank.
Common Reasons for SRS Codes
SRS codes can be triggered by a variety of issues, including:
- Faulty sensors: These sensors detect a crash and trigger the airbag deployment. A faulty sensor can cause the airbag warning light to illuminate.
- Damaged wiring: Electrical problems like broken wires, corroded connections, or short circuits can affect the airbag system.
- Faulty airbag module: The airbag control module (ACM) is the brain of the airbag system. A faulty ACM can cause malfunctions and trigger error codes.
- Deployed airbag: If an airbag has been deployed, the system must be reset, which typically requires specialized tools and procedures.

How to Use a Scan Tool to Read SRS Code
Using a scan tool to read SRS codes is a straightforward process, but it’s important to follow the correct steps:
- Connect the scan tool: Connect the scan tool to your car’s diagnostic port, usually located under the dashboard near the steering wheel.
- Select the vehicle: Select your car’s make, model, and year from the scan tool’s menu.
- Read the codes: Once the scan tool has established communication with the car, select the SRS module to read the stored codes.
- Interpret the codes: The scan tool will display a list of SRS codes with descriptions. Use the tool’s help function or a code lookup resource to understand the meaning of the codes.
- Clear the codes: Once you have identified and addressed the problem, you can clear the codes using the scan tool.
Tips for Troubleshooting SRS Codes
- Use a reputable scan tool: Avoid cheap or unreliable scan tools, as they can provide inaccurate readings.
- Consult a service manual: Use the car’s service manual or online resources to understand the specific steps for troubleshooting and repairing SRS codes.
- Be cautious: Work on the airbag system only if you are comfortable with electrical repairs and are aware of the potential risks involved.
- Seek professional help: If you are unsure about any part of the process or are dealing with a complex issue, contact a qualified mechanic.
