The Autel MX808 is a powerful diagnostic tool popular among car enthusiasts and professional mechanics. One common question is whether it can reset an airbag light. The answer is a resounding yes, the Autel MX808 can reset an airbag light. This article will explain how the MX808 handles airbag systems, guide you through the reset process, and discuss important considerations.
Understanding Airbag Systems and the Autel MX808
Modern vehicles rely on complex airbag systems for occupant safety. When a collision occurs, sensors trigger the deployment of airbags to cushion the impact. The system’s control module constantly monitors these sensors. If a fault is detected, such as a disconnected sensor or a low voltage issue, the airbag light illuminates on the dashboard. This indicates a potential problem that needs attention.
The Autel MX808 excels at diagnosing these issues. It can communicate with the airbag module (often referred to as SRS or Supplemental Restraint System), read fault codes, and provide crucial information about the nature of the problem. More importantly, after addressing the underlying issue, the MX808 allows you to clear the fault codes and reset the airbag light.
Resetting the Airbag Light with the Autel MX808: A Step-by-Step Guide
- Connect the MX808: Plug the device’s OBD-II connector into your vehicle’s OBD-II port, usually located under the dashboard on the driver’s side.
- Power On: Turn on the ignition key to power the vehicle’s electrical system, but do not start the engine. Then, power on the Autel MX808.
- Vehicle Selection: The MX808 will prompt you to select the vehicle’s make, model, and year. Ensure accurate information for proper communication. Automatic VIN detection can often streamline this process.
- System Selection: Navigate to the “Diagnostics” menu and select “SRS” or “Airbag.”
- Read Fault Codes: Initiate a scan to retrieve diagnostic trouble codes (DTCs) stored in the airbag module. These codes pinpoint the specific problem area.
- Diagnose and Repair: Based on the retrieved codes, diagnose the issue. This may involve inspecting wiring, connectors, sensors, or the airbag module itself. Repair the problem accordingly. Crucially, always disconnect the battery’s negative terminal before working on any airbag system component.
- Erase Codes: After the repair, return to the MX808 and select the option to erase or clear the fault codes. This action resets the airbag light.
- Verify the Fix: Perform another scan to confirm that no fault codes remain. If the light stays off, the repair was successful.

Important Considerations
- Safety First: Airbag systems deal with explosive components. Exercise extreme caution when working on them. If unsure, consult a qualified mechanic. Disconnecting the battery’s negative terminal is crucial before any airbag system repairs.
- Underlying Issues: Simply resetting the light without addressing the root cause is dangerous. The airbag system may not function correctly in a future collision. Thorough diagnosis and repair are essential.
- Professional Help: While the Autel MX808 is a user-friendly tool, complex airbag issues may require professional expertise. Don’t hesitate to seek help when needed.

Conclusion
The Autel MX808 is a valuable tool for diagnosing and resetting airbag lights. It empowers car owners and mechanics to address safety-critical issues. However, always prioritize safety, diagnose the root cause of the problem, and seek professional assistance when necessary. The MX808 provides the information you need, but proper repair ensures your airbag system functions as intended, protecting you and your passengers.
