The SRS (Supplemental Restraint System) is a critical safety feature in your Mercedes Benz, encompassing airbags, seatbelt tensioners, and sensors. After an accident or airbag deployment, the SRS system needs to be reset. This often requires a specialized tool known as an “SRS reset tool.”
Understanding the SRS System and Reset Tools
The SRS system is designed to activate during a collision, minimizing the impact on passengers. After deployment, even if there’s no visible damage, the system needs a reset to function correctly. This is where an SRS reset tool comes in.
What Does a Mercedes Benz SRS Reset Tool Do?
- Reads and Clears Fault Codes: The tool can diagnose the reason for the SRS light being on, identifying specific fault codes stored in the system.
- Resets the SRS Module: Once the issue is resolved, the tool can reset the SRS module, turning off the warning light and enabling the system.
Types of SRS Reset Tools
There are various types of SRS reset tools available, from basic code readers to advanced professional scanners.
- OBD-II Scanners with SRS Functionality: These are widely available and can read and clear basic SRS codes.
- Mercedes-Benz Specific Scanners: These offer more advanced functionality, including the ability to reset the SRS module on a wider range of Mercedes models.

FAQs about Mercedes Benz SRS Reset Tools

What happens if I don’t reset the SRS light after an accident?
The SRS system may not function correctly in a subsequent collision. Additionally, the warning light will remain illuminated, potentially leading to failed safety inspections.
