Imagine this: you’re driving your Subaru down a winding country road, enjoying the scenery, when suddenly, the engine starts sputtering and the check engine light flashes. You pull over, your heart sinking, and wonder: “Why can’t I use my trusty OBD2 scan tool to figure out what’s wrong?”. This is a common frustration for many Subaru owners, and we’re here to unravel the mystery.
Understanding The Why
The “why” behind this issue lies in Subaru’s commitment to advanced technology and security. While many cars in the market readily accept OBD2 scan tools, Subaru utilizes a more complex system called the “Proprietary Diagnostic Network”. This network, designed for increased control and diagnostics, often makes it difficult for generic OBD2 tools to access and read data from your Subaru.
Why Does Subaru Do This?
Subaru has implemented its own network for various reasons, including:
- Increased Security: The proprietary network helps prevent unauthorized access to your vehicle’s systems, potentially mitigating the risk of hacking or manipulation. This is especially important as cars become increasingly connected and reliant on software.
- Enhanced Diagnostics: Subaru’s network is designed for advanced diagnostics that go beyond the basic information provided by a standard OBD2 tool. This allows Subaru technicians to have a deeper understanding of potential issues and perform more accurate diagnoses.
- Future-Proofing: The proprietary network enables Subaru to easily introduce new features and technologies without worrying about compatibility issues with generic OBD2 tools.
What Does This Mean For You?
So, while it might seem frustrating, Subaru’s decision is ultimately meant to protect you and your vehicle. But what can you do if your Subaru throws a code and you need a diagnostic?
Subaru’s Diagnostic Solution
The good news is that Subaru offers their own solutions for reading codes and performing diagnostics on their vehicles. They have developed their own Subaru Select Monitor (SSM) software that is available at dealerships and authorized repair shops. This software is specifically designed to work with Subaru’s proprietary network and provide comprehensive diagnostic information.
Alternatives and Hacks
While the SSM is the recommended route for accurate Subaru diagnostics, there are a few alternative methods that might offer a glimpse into your car’s issues:
- Generic OBD2 Scan Tools: While they might not access all the data, some OBD2 scan tools can read basic engine codes, which might offer a starting point for troubleshooting. Remember, the information you get might be limited.
- Third-Party Software: A few third-party software developers have attempted to create tools compatible with Subaru’s proprietary network, but their reliability and accuracy can vary.
Common Questions
Q: Will using a generic OBD2 scan tool damage my Subaru?
No, using a generic OBD2 tool won’t damage your Subaru. However, it might not be able to access all the necessary information to accurately diagnose a problem.
Q: Are there any specific OBD2 tools that work with Subarus?
There are a few OBD2 tools marketed as being “Subaru compatible”. However, their effectiveness can vary, and it’s always recommended to consult a Subaru specialist for accurate diagnosis and repair.
Q: Where can I find a Subaru dealer or authorized repair shop near me?
You can easily find a Subaru dealer or authorized repair shop near you using Subaru’s website or a simple online search.
Conclusion
While it might be frustrating to find your OBD2 scan tool isn’t compatible with your Subaru, remember that this decision is ultimately aimed at protecting you and your vehicle. Utilize the tools and resources provided by Subaru for accurate diagnostics, and remember that a professional mechanic is always your best bet for a comprehensive understanding and resolution of any issues.
