Finding the right OBDII software to check ABS can be challenging with so many options available. This article discusses the differences between generic and manufacturer-specific scan tools, helping you choose the best one for your needs. Understanding the capabilities of each type is crucial for effective diagnostics.
Global OBDII vs. Manufacturer Data
All OBDII scanners can read Global OBDII data, a standardized set of information required for all vehicle manufacturers since 1996. This allows basic diagnostics across various car makes and models. However, more in-depth diagnostics require access to manufacturer-specific data, which is not always available through Global OBDII. This data provides detailed insights into systems like ABS, transmission, engine, and body control modules. While generic scanners can often read ABS codes for common manufacturers like GM, Ford, and Chrysler, accessing comprehensive ABS data usually requires a more advanced tool.
Choosing the Right Scanner for ABS Diagnostics
For DIY enthusiasts working primarily on a single vehicle make, the Foxwell NT510 is a powerful option. Priced around $170 on Amazon, it offers comprehensive manufacturer-specific data, including ABS, for a chosen vehicle make. It also provides bidirectional control, enabling users to activate components like cooling fans or the AC clutch for diagnostic testing. This functionality is a significant advantage, mirroring the capabilities of professional-grade scan tools used in repair shops. The NT510 allows for up to five manufacturer-specific software licenses, each costing around $60, but note that not all manufacturers are supported.
If you need a scanner capable of reading manufacturer-specific data across a wider range of vehicles, the Autel MD802 is a viable alternative in the same price range as the Foxwell NT510. While it lacks bidirectional control, it excels at retrieving both Global OBDII and manufacturer-specific data for most vehicles manufactured since 1996. Keep in mind that data availability and communication can vary for vehicles between 1996 and 2000 due to the evolving OBDII standard. For example, accessing manufacturer-specific engine data on a 1998 Nissan 200SX might require a specialized factory scan tool due to a unique diagnostic port. While the MD802 might only provide Global OBDII data in such cases, it remains a versatile tool capable of comprehensive diagnostics on a broader range of vehicles. A higher-end scanner, like the Autel DS708, could access this specialized data through the manufacturer’s specific port.
