Finding the best budget OBD2 scanner in 2018 can be challenging with so many options available. This post shares real-world experiences with several popular models, including the Autel MD805, Foxwell NT630 Elite, Launch CRP123, and Autel AL539, highlighting their strengths and weaknesses. We’ll delve into their performance on various vehicles and specific diagnostic tasks to help you make an informed decision.
Budget OBD2 Scanner Showdown: Features and Performance
The Autel MD805 initially impressed with its auto-search functionality, correctly identifying vehicle models and engine types. However, it struggled with a 2005 Toyota Camry, failing to perform any scans despite recognizing the vehicle. While successful on other vehicles, including graphing wheel speed sensors on a 2013 Ford Ranger, the MD805’s graphing was limited to two sensors at a time.
Autel MD805 OBD2 Scanner
The Foxwell NT630 Elite proved to be a strong contender. It successfully diagnosed and resolved an ABS issue on a Lexus LS430, pinpointing a lost zero-point calibration and offering a test mode to reset it. This functionality contrasted sharply with the MD805, which could only perform basic OBD2 code scans on the same vehicle. The Launch CRP123 could read codes but lacked the special functions offered by the Foxwell NT630 Elite.
The Autel AL539, despite previous update issues, remained a favorite due to its impressive I/M readiness mode. This feature allowed for real-time monitoring of engine parameters and pending fault codes, demonstrating its diagnostic capabilities. While testing on a Lexus, it quickly identified an open circuit VSV solenoid and unresponsive VVT solenoids.
Update issues with the Autel AL539 and AL539B were a concern. Menu language changing to numbers and disappearing icons after updates indicated the need for improvement in Autel’s update system. In contrast, Foxwell and Launch provided flawless update experiences.
Conclusion: Choosing the Best Budget OBD2 Scanner
Each budget OBD2 scanner tested offered different strengths and weaknesses. The Foxwell NT630 Elite excelled in functionality, particularly with ABS diagnostics. The Autel AL539 provided valuable real-time engine monitoring. The Autel MD805, while affordable, had limitations in functionality and compatibility. The Launch CRP123 served as a basic code reader but lacked advanced features.
Ultimately, the best budget OBD2 scanner for 2018 depends on your specific needs and budget. Consider the types of vehicles you work on and the diagnostic tasks you need to perform. Researching and comparing different models, as demonstrated in this post, is crucial for finding the right tool for your automotive repair needs.
