Dealing with the persistent SRS (Supplemental Restraint System) light in your Volvo can be frustrating and concerning. This crucial safety system, which includes airbags and seatbelts, requires immediate attention when the warning light illuminates. While a trip to the mechanic is always an option, Volvo owners seeking a DIY approach to diagnostics and maintenance often turn to OBD2 scanners. But not all scanners are created equal, especially when it comes to resetting the Volvo SRS light. This guide will help you navigate the options and choose the best OBD2 scanner to confidently reset your Volvo’s SRS system and ensure your vehicle’s safety features are functioning correctly.
Understanding the Volvo SRS System and Resetting Needs
The SRS light, also known as the airbag light, signals a potential issue within your Volvo’s safety restraint system. This could range from minor sensor glitches to more serious problems with airbags, seatbelt pretensioners, or related components. When the SRS light is on, it indicates that the system may not deploy correctly in an accident, compromising your safety and that of your passengers.

Troubleshooting Common SRS Issues Before Resetting
Before you rush to reset the SRS light, it’s crucial to understand why it came on in the first place. Simply clearing the code without addressing the underlying issue might only lead to the light reappearing.
A common culprit for SRS light activation in Volvos, particularly older models, is related to the connectors under the seats. These connectors are part of the seatbelt pretensioner and side airbag circuits. Movement of the seats, or even just time and vibration, can cause these connectors to become loose or corroded, leading to intermittent SRS faults.
As one Volvo owner shared, “I’ve already wiggled the connectors under the seat but I guess it’s still an issue with those cables?” This “wiggling” is actually a common first step in troubleshooting SRS light issues related to seat connectors. Disconnecting and reconnecting these connectors, and even cleaning the pins, can sometimes resolve the problem. In one forum case, a user “bent the connector pins (significantly) and carefully put the connector back together, solved the problem,” highlighting the sensitivity of these connections.
Other potential causes for SRS light activation can include:
- Faulty SRS components: Airbags, seatbelt pretensioners, sensors.
- Clock spring issues: Located in the steering column, the clock spring can fail and affect airbag circuits.
- Low battery voltage: In some cases, a low battery can trigger SRS faults.
It’s always recommended to perform a diagnostic scan to retrieve the specific SRS fault codes before attempting a reset. This code will provide valuable information about the source of the problem, guiding your troubleshooting efforts. As emphasized in the forum, “You need to know why it came on in the first place. Turning it off may mean it comes straight back on….”
Step-by-Step Guide to Resetting Volvo SRS Light with OBD2 Scanner
Disclaimer: Resetting the SRS light should only be done after diagnosing and addressing the underlying issue. If you are unsure about the cause of the SRS light or are not comfortable working on safety systems, consult a qualified mechanic.
