Understanding your vehicle’s health is crucial, and OBD2 scanners are the key to unlocking your car’s diagnostic data. Since the late 1990s, all cars have been equipped with OBD2 ports, mandated to support generic access for engine-related issues. However, the depth of information you can access varies significantly between scanner types. Navigating the world of OBD2 scanners can be confusing, so let’s break down what you need to know to choose the right tool for your needs in 2018.
Generic OBD2 Scanners: The Basics
Generic OBD2 access is a standard feature, allowing any basic scanner to pull engine-related fault codes. These scanners are often inexpensive and can perform fundamental functions like clearing check engine lights and reading generic engine codes. For simple issues like a misfire, a generic scanner might suffice. However, their capabilities are limited.
Generic scanners provide very basic engine-only information. They offer no access to other crucial vehicle systems such as transmission, airbags, ABS, or climate control. For more complex problems, especially those outside the engine compartment, a generic scanner simply won’t provide the necessary insights. Troubleshooting issues like turbo faults or transmission problems requires a more advanced tool.
OEM-Specific OBD2 Scanners: Deeper Diagnostics
Car manufacturers also incorporate their own OEM-specific codes, which offer far more detailed and precise fault information than generic codes. These codes can pinpoint problems with greater accuracy and often cover systems beyond just the engine. However, generic, low-cost code readers cannot access or reset these OEM-specific codes.
Accessing OEM-specific data requires scanners capable of speaking the unique language of each manufacturer. A scanner designed for Ford OEM-specific data, for instance, will generally not be compatible with BMW or Toyota specific information. This is where professional-level scanners come into play.
Professional, high-end scanners are designed to access OEM-specific information across a wide range of manufacturers. These scanners offer comprehensive diagnostics, often reaching into all vehicle control modules. However, this advanced functionality comes at a significant cost, typically ranging from $2,000 to $5,000. For the average car owner, this price point is prohibitive.
The Rise of Affordable Multi-System Scanners
For those seeking more than generic capabilities without the hefty price tag of professional scanners, options like the Foxwell NT510/520 emerged as excellent alternatives in 2018. These scanners offer a unique balance of affordability and comprehensive access. The Foxwell NT510/520, for example, is a low-cost tool that supports multiple OEM-specific software packages.
Starting at around $150, the Foxwell NT510/520 includes one OEM-specific software package, with additional packages available for purchase at approximately $60 each. The BMW software for the NT510 is particularly noteworthy, providing access to virtually all electronic control units in the car, including engine, transmission, ABS, airbags, climate control, and more. This level of access was previously only found in scanners costing thousands of dollars.
Choosing the Right OBD2 Scanner in 2018
When selecting an OBD2 scanner in 2018, consider your needs and budget. For basic engine code reading and check engine light resets, a generic scanner might suffice. However, for deeper diagnostics, access to more vehicle systems, and OEM-specific codes, investing in a multi-system scanner like the Foxwell NT510/520 can be incredibly beneficial. While “10 best” is subjective and depends heavily on individual needs, the Foxwell NT510/520 stood out in 2018 as a top recommendation for its combination of affordability and comprehensive capabilities, especially for enthusiasts and DIY mechanics working with multiple vehicle brands or requiring in-depth diagnostics beyond basic engine codes. Tools like the Foxwell represent a significant leap in accessible automotive diagnostic technology, bringing near-professional level scanning within reach of a wider audience.
