Navigating car troubles, especially with a classic like the 1999 Volvo V70, often begins with understanding those cryptic fault codes. If your check engine light is on, or you’re facing other dashboard warnings, an OBD2 code reader is your first step towards diagnosing the issue. This guide will walk you through selecting the best OBD2 reader for your 1999 Volvo V70, ensuring you can effectively read and understand those crucial OBD2 codes.
Understanding OBD2 and Your 1999 Volvo V70
The 1999 Volvo V70 is OBD2 compliant, meaning it utilizes the second generation of on-board diagnostics. This system is designed to monitor various aspects of your car’s performance and emissions. When something goes wrong, the system generates diagnostic trouble codes (DTCs), which can be accessed using an OBD2 scanner or code reader. These codes are invaluable for pinpointing problems, from minor sensor glitches to more significant mechanical issues.
Basic OBD2 Code Readers: Are They Enough for a ’99 V70?
For many 1999 Volvo V70 owners, a basic OBD2 code reader is an excellent starting point. These readers, often found at affordable prices online and in auto parts stores, are capable of:
- Reading Engine Fault Codes: They can retrieve generic OBD2 codes related to engine and emissions systems, helping you identify why your check engine light might be illuminated.
- Resetting the Check Engine Light (MIL): Once you’ve addressed the issue, these readers can usually clear the fault codes and turn off the check engine light.

As mentioned in forums, users have found success with inexpensive readers for basic engine code diagnostics on their 1999 V70s. These tools are user-friendly and require no software installation, making them a convenient option for quick diagnostics.
Beyond Engine Codes: Addressing the SRS Light on a 1999 Volvo V70
However, the limitations of basic OBD2 readers become apparent when dealing with systems beyond the engine and emissions. A common concern for Volvo V70 owners is the SRS (Supplemental Restraint System) light, related to airbags and safety systems.
Unfortunately, basic, budget-friendly OBD2 readers typically cannot reset the SRS light on a 1999 Volvo V70. These systems often require more specialized diagnostic tools that can communicate with Volvo-specific modules.
As forum discussions highlight, even some garages with professional-grade equipment struggle to access and reset the SRS system on these models. This is where more advanced options come into play.
Advanced Diagnostic Tools for Comprehensive Volvo V70 Diagnostics
For a more in-depth diagnosis and the ability to tackle issues like the SRS light, you might need to consider advanced diagnostic tools:
-
VOL-FCR Software: As mentioned by forum users, VOL-FCR is a software option designed for Volvo vehicles. It offers more in-depth diagnostics than basic readers and may be capable of accessing and resetting the SRS light, along with other Volvo-specific systems.
-
VIDA/DiCE (Diagnostic Communication Equipment): VIDA is Volvo’s official diagnostic software, and DiCE is the hardware interface that connects your car to a computer running VIDA. This is a powerful combination used by Volvo technicians and serious DIYers. VIDA/DiCE provides comprehensive access to all Volvo systems, including SRS, ABS, and more, offering code reading, resetting, and even programming capabilities.

- Professional Scan Tools: Certain professional-grade scan tools from brands like BSR PPC, VCT, and Auto Diagnosis (mentioned in the forum) may also offer enhanced capabilities for Volvo vehicles, potentially including SRS reset functions. These tools often come with a higher price tag but provide broader vehicle coverage and advanced features.
Choosing the Right OBD2 Reader for Your Needs
The best OBD2 reader for your 1999 Volvo V70 depends on your specific needs and budget:
- For basic engine code reading and check engine light resets: A basic OBD2 reader from eBay or Amazon (in the £20-£50 range) can be sufficient.
- For SRS light reset and more comprehensive diagnostics: You will likely need to invest in a more advanced tool. Options include VOL-FCR software (check compatibility and features carefully), a VIDA/DiCE unit (more expensive but most comprehensive), or a professional scan tool with Volvo-specific capabilities (price varies).
Locating the OBD2 Port:
Regardless of the reader you choose, the OBD2 port in your 1999 Volvo V70 is conveniently located under the front center armrest. Simply lift the cover marked “OBDII” to access the connector.
Conclusion: Empowering Your 1999 Volvo V70 Diagnostics
Understanding OBD2 codes is crucial for maintaining your 1999 Volvo V70. While basic OBD2 readers are valuable for engine-related issues, addressing systems like SRS might require a more significant investment in specialized diagnostic tools. By evaluating your needs and exploring the options, you can choose the right OBD2 reader to confidently diagnose and maintain your classic Volvo V70.
