Finding a reliable and affordable diagnostic scan tool for your car can be challenging. This FAQ addresses common questions about OBD2 scanners, helping you find the best diagnostic scan tool for all cars in 2019 under $300.
Common Questions About OBD2 Scanners
Is the RepairSolutions2 App Required?
The RepairSolutions2 app is completely optional and free. While it’s not mandatory, it enhances the diagnostic process with features like ASE-certified repair recommendations, scan export capabilities, predicted repairs, access to technical service bulletins, and more. Using the app is highly recommended for a comprehensive diagnostic experience.
Are Software Updates Free?
Yes, all software updates are free, and there are no subscription fees. You’ll always have access to the latest features and bug fixes without any recurring costs.
Does the Scanner Work Internationally?
The device and app are designed for use within the United States and Canada. They adhere to North American OBD protocols and may not function correctly in other regions. It might work in Mexico with US-imported vehicles.
Will It Work on My Specific Vehicle?
While compatible with most OBD2-compliant vehicles (1996 and newer in the US), functionality can vary depending on the year, make, and model. Use a vehicle coverage checker to confirm compatibility before purchasing.
FCA Vehicle Compatibility (Jeep, Chrysler, etc.)?
For FCA vehicles manufactured in 2017 or earlier, the scanner can diagnose all systems. For 2018 and newer models requiring AutoAuth access, functionality is limited to features like TPMS relearn and live data. It won’t perform tasks like code erasure, oil resets, or battery initialization due to AutoAuth restrictions. Consider a dedicated FCA-compatible scan tool with AutoAuth access for full functionality on newer models.
Can It Reprogram Vehicle Computers or Program Key Fobs?
No, this scanner cannot reprogram vehicle computers or program key fobs. It’s primarily designed for diagnostic purposes, reading and clearing codes, and accessing live data.
Will It Work on a Car That Won’t Start or Crank?
No, OBD2 scanners require the vehicle’s engine to crank or start to establish communication with the Electronic Control Units (ECUs). If the engine doesn’t crank, the scanner can’t connect.
Conclusion
A quality diagnostic scan tool is essential for car owners. While there are limitations, an OBD2 scanner under $300 can provide valuable insights into your vehicle’s health. Be sure to verify vehicle compatibility and understand the scanner’s capabilities before making a purchase.
