That’s indeed a very pertinent question when dealing with modern vehicle diagnostics. Understanding what type of code reader you need for your car, especially when considering CAN OBDII systems, can be crucial. Let’s break down the options to ensure you’re equipped with the right tool for the job.
For basic diagnostics, almost any standard OBD2 reader will access and display the “P” codes, which relate to powertrain issues, on most vehicles equipped with OBDII. However, this is where the simplicity ends. If you need to delve deeper into your vehicle’s systems, particularly for modules like the Transmission Control System (TCM) or Anti-lock Braking System (ABS), a generic OBD2 reader might fall short. These readers often lack the capability to access codes beyond the basic powertrain diagnostics, leaving you in the dark regarding critical system malfunctions.
Moving beyond basic readers, specialized tools come into play. In the realm of professional-grade equipment, historically, there were options like the Programmable Diagnostic Unit (PDU), a powerful but rare and expensive tool capable of comprehensive diagnostics. Another option was the Worldwide Diagnostic System (WDS), which offered extensive capabilities, although it had limitations in certain areas like resetting base idle adaptations. These systems were designed for in-depth analysis and control, but are often overkill and cost-prohibitive for the average user or smaller repair shops.
For a more accessible yet still robust option, the Genrad 500 or 510 handheld code readers were notable. These devices could not only read codes across various modules but also monitor live data points within the vehicle’s systems. While they provided a significant step up from basic readers, their functionality was primarily limited to code reading and data monitoring. They couldn’t perform actuation or reset procedures like Throttle Position Sensor (TPS) resets or oxygen sensor re-orientation, functions that the more advanced WDS and PDU systems could handle. The Genrad readers, though capable, are also becoming increasingly rare to find on the market.
As technology advanced and became more accessible, brands like AUTEL and FOXWELL emerged, offering diagnostic tools that bridge the gap between basic readers and high-end professional systems. The question then becomes: do AUTEL or FOXWELL units read ABS and Transmission codes on older vehicles, especially those utilizing CAN OBDII? The answer often depends on the specific model of the reader and the vehicle in question. It’s advisable to consult online forums and communities dedicated to your specific vehicle make and model to find real-world user experiences and confirmations of compatibility. Searching forums for owners of vehicles with engines similar to the AJ16, for example, might yield valuable insights into reader compatibility for your specific needs.

Exploring options from brands like AUTEL and FOXWELL, and considering the tested models listed above, can guide you to the right code reader for comprehensive vehicle diagnostics. Remember to always verify compatibility with your specific vehicle year and model before purchasing a reader to ensure it meets your diagnostic needs.
