Navigating car troubles can be frustrating, especially when your trusty OBD2 scanner fails to communicate with your Volvo V70. Many Volvo V70 owners have encountered this issue, discovering that not all OBD2 scanners are created equal when it comes to reading Volvo’s proprietary systems. This article delves into the world of OBD2 scanners for Volvo V70s, ensuring you find the perfect tool to diagnose and maintain your vehicle without breaking the bank.
Understanding the necessity of a reliable OBD2 scanner is the first step. For Volvo V70 owners, a generic scanner might only scratch the surface, reading basic OBD-II codes but missing crucial Volvo-specific fault codes. This limitation can leave you in the dark regarding issues within systems like ABS, SRS, or Volvo’s unique engine and transmission controls. The original forum discussion highlights this exact problem: owners struggling to find a “simple low cost scanner” that truly reads their Volvo XC70 (essentially a V70 XC).
Why Generic OBD2 Scanners Might Fall Short for Volvo V70
While OBD2 is a standardized system, manufacturers like Volvo often incorporate proprietary diagnostic protocols beyond the basic OBD-II requirements. These enhanced systems allow for deeper diagnostics and access to a wider range of vehicle data, including Volvo-specific Diagnostic Trouble Codes (DTCs). Generic OBD2 scanners are designed to read the standard codes mandated across all OBD2 compliant vehicles, which are primarily emissions-related. Therefore, when you plug a generic scanner into your Volvo V70, it might only retrieve a limited set of codes, potentially missing critical information about your car’s health.
Exploring Effective OBD2 Scanner Options for Volvo V70
Fortunately, there are several OBD2 scanner options that cater specifically to Volvo vehicles, including the V70. These options range from professional-grade systems to more affordable aftermarket tools.
1. Volvo VIDA/DiCE: The Dealership-Level Diagnostic Solution
For the most comprehensive diagnostic capabilities, Volvo VIDA (Vehicle Information and Diagnostics for Aftersales) combined with the DiCE (Diagnostic Communication Equipment) interface is the gold standard. VIDA/DiCE is the same system used by Volvo dealerships and professional independent repair shops.

Pros of VIDA/DiCE:
- Unmatched Diagnostic Depth: VIDA/DiCE provides access to virtually all Volvo systems, reading and clearing both generic OBD-II codes and Volvo-specific DTCs.
- Comprehensive Functionality: Beyond code reading, VIDA allows for advanced functions like module programming, software updates, service resets, and access to repair information and wiring diagrams.
- Dealer-Level Capability: This is the tool Volvo technicians use, ensuring you have the most thorough diagnostic information available.
Cons of VIDA/DiCE:
- Cost and Complexity: Genuine VIDA/DiCE systems are expensive, requiring software subscriptions and specialized hardware. “Clone” versions are available at significantly lower prices (as mentioned in the forum thread for around $125-$150), but can come with installation challenges and potential reliability issues.
- Software Requirements: VIDA software typically requires older Windows operating systems like Windows XP Pro and specific hardware configurations, although workarounds exist.
- Learning Curve: VIDA is a professional tool with a steep learning curve for non-professionals.
Despite these drawbacks, for Volvo enthusiasts and owners who demand the most in-depth diagnostics, a VIDA/DiCE system (even a cloned version) can be a worthwhile investment, as highlighted by several users in the forum thread.
2. Aftermarket Volvo-Specific OBD2 Scanners: A Balanced Approach
For users seeking a more user-friendly and cost-effective alternative to VIDA/DiCE, several aftermarket OBD2 scanners are designed with enhanced Volvo compatibility. Brands like iCarsoft (specifically models like the i906 mentioned in the forum) and others offer scanners that can read Volvo-specific codes and perform some advanced functions beyond generic OBD2 scanners.

Pros of Aftermarket Volvo-Specific Scanners:
- Volvo Enhanced Diagnostics: These scanners go beyond basic OBD-II, reading Volvo-specific fault codes for systems like ABS, SRS, engine, and transmission.
- User-Friendly Interface: Typically designed for ease of use with intuitive menus and clear displays.
- More Affordable than VIDA/DiCE: Significantly less expensive, making them accessible to a wider range of Volvo owners.
- Portability: Often handheld and compact, making them easy to use in your garage or on the go.
Cons of Aftermarket Volvo-Specific Scanners:
- Less Comprehensive than VIDA/DiCE: While they offer enhanced Volvo diagnostics, they may not have the full depth of functionality of VIDA/DiCE, especially for advanced programming or module updates.
- Varying Levels of Capability: The features and Volvo system coverage can vary between different brands and models of aftermarket scanners. Researching specific models and reviews is crucial.
3. Generic OBD2 Scanners: Basic Diagnostics for Standard Codes
Generic OBD2 scanners, readily available at auto parts stores and online, can still be useful for Volvo V70 owners, particularly for reading basic OBD-II codes related to engine emissions.

Pros of Generic OBD2 Scanners:
- Low Cost and Accessibility: Very affordable and widely available.
- Easy to Use: Simple plug-and-play operation for basic code reading.
- Suitable for Basic Emissions-Related Issues: Can diagnose common problems that trigger the check engine light related to emissions.
Cons of Generic OBD2 Scanners:
- Limited Volvo-Specific Diagnostics: Will likely miss Volvo-specific fault codes and provide limited system coverage beyond basic OBD-II.
- May Not Read All Systems: May not communicate with all modules in your Volvo V70.
- Limited Functionality: Typically restricted to reading and clearing codes, with minimal or no advanced functions.
Choosing the Right OBD2 Scanner for Your Volvo V70
The best OBD2 scanner for your Volvo V70 depends on your needs, budget, and technical expertise.
- For Comprehensive Diagnostics and Professional-Level Capability: VIDA/DiCE (or a reputable clone) is the ultimate choice, despite the cost and complexity.
- For Enhanced Volvo Diagnostics with User-Friendliness and Affordability: An aftermarket Volvo-specific scanner from a reputable brand like iCarsoft provides a strong balance.
- For Basic Code Reading and Emissions-Related Issues on a Budget: A generic OBD2 scanner can be a starting point, but understand its limitations for Volvo-specific problems.
Conclusion: Empowering Your Volvo V70 Ownership with the Right OBD2 Scanner
Investing in the right OBD2 scanner is a crucial step in proactively maintaining your Volvo V70. While generic scanners have their place for basic checks, Volvo V70 owners will benefit significantly from scanners with enhanced Volvo-specific diagnostic capabilities. Whether you choose the in-depth power of VIDA/DiCE or the balanced approach of an aftermarket Volvo-specific tool, having the ability to accurately diagnose your vehicle empowers you to address issues promptly, saving you time and money in the long run. Explore the options discussed, consider your needs, and equip yourself with the best OBD2 scanner to keep your Volvo V70 running smoothly for years to come.
