When your car’s check engine light illuminates, it’s often the first sign that something is amiss. These warning lights are triggered by diagnostic trouble codes (DTCs) stored in your vehicle’s computer. To understand and address these issues, and importantly, to reset these codes after repair, you’ll need an OBD2 scanner. But with a vast market of options, finding the Best Obd2 Scanner For Reset Codes can feel overwhelming. This guide will help you navigate the choices and select the right tool for your automotive diagnostic needs.
Understanding OBD2 access is crucial when choosing a scanner. There are two primary types: generic and OEM-specific. Since the late 1990s, all cars have been mandated to support generic OBD2 access. This standardized system allows any basic OBD2 scanner to read a limited set of generic, engine-related fault codes. These scanners can perform fundamental functions like clearing these generic fault codes and turning off the check engine light. For straightforward issues, such as a simple engine misfire, a generic scanner might suffice to reset the code after you’ve completed the repair.
However, the capabilities of generic OBD2 scanners are quite limited. They primarily focus on engine-related problems and often fall short when diagnosing more complex issues, such as turbocharger faults or problems in other vehicle systems. Generic scanners cannot access the multitude of other electronic control units (ECUs) within your car, such as those governing the transmission, airbags, anti-lock braking system (ABS), and more.
For a more in-depth diagnosis and the ability to reset codes across various vehicle systems, you’ll need a scanner capable of OEM-specific access. Each car manufacturer has its own unique set of OEM-specific codes, which provide far more detailed and precise fault information than generic codes. “Cheap” generic code readers simply cannot read or reset these manufacturer-specific codes. Due to the proprietary nature of these systems, a scanner designed to access Ford’s OEM-specific data will generally not be compatible with the OEM systems of other manufacturers like Toyota or BMW.
Professional-grade, more expensive scanners, typically priced in the $2,000 to $5,000 range, offer access to OEM-specific information for a wide range of manufacturers. While these tools are incredibly powerful, their cost is prohibitive for the average car owner or DIY enthusiast. There are some exceptions, such as Peake Research, which offers relatively affordable BMW-specific diagnostic tools for around $150.
Among the low-cost options, the Foxwell NT510 and NT520 series scanners stand out as exceptional tools that support multiple OEM brands. Starting at around $150, the Foxwell NT510/520 allows users to purchase and load OEM-specific software packages for different manufacturers, typically costing about $60 per brand. For example, the BMW software package for the NT510 is highly regarded, granting access to virtually all electronic systems in the car – including the engine, transmission, brakes, ABS, traction control, airbags, audio, navigation, climate control, locks, alarm system, and more. This comprehensive access makes the Foxwell scanner a powerful tool for both diagnostics and resetting codes beyond just the basic engine functions.
In conclusion, for car owners seeking the best OBD2 scanner for reset codes that balances capability and affordability, the Foxwell NT510/520 is a compelling choice. The initial investment of $150 includes one OEM-specific software package, making it an excellent entry point. If you primarily work on a specific brand, like BMW, the Foxwell at this price point offers outstanding value and comprehensive diagnostic and code resetting capabilities that can quickly pay for itself through DIY repairs and maintenance.
