For car owners and auto repair enthusiasts, understanding what’s going on under the hood is crucial. Basic OBD2 scanners are readily available at places like Walmart and auto parts stores such as O’Reilly’s, Pep Boys, Autozone, Advanced Auto Parts, and Napa. These tools are useful for reading and clearing basic diagnostic trouble codes (DTCs). However, for more in-depth diagnostics and access to advanced vehicle systems, professional-grade scanners like Cornwell Obd2 Scanners become essential.
These auto parts retailers also offer upgraded OBD2 scanners, including Bluetooth-enabled versions like the FixIt scanners, catering to users who need more features than the most basic models. Checking online or in-store availability beforehand can save time and ensure you find the right tool without dealing with subpar service.
Pawn shops can be a surprising source for used OBD2 scanners at bargain prices, offering a budget-friendly way to acquire diagnostic tools. Brands like Craftsman, Innova, Autel, Actron, Snap-on, Cornwell, and Matco are well-regarded in the market, offering a range of scanners from basic to high-end models costing over $1,000.
When it comes to top-tier OBD2 scanners, brands like Innova, Autel, Snap-on, Cornwell, and Matco stand out. Autel, in particular, is known for a wide selection of features and capabilities. Cornwell Tools also offers professional-grade scanners designed for automotive technicians and serious DIYers.

Personal experiences highlight the value of investing in a more advanced scanner. For example, purchasing a barely used Autel Maxicheck 808 from a pawnshop for a significantly reduced price ($350 compared to a $500+ website price) provided access to features beyond basic code reading. Depending on the vehicle, these advanced scanners can access and control systems that are typically sealed off to basic tools.
On a 2011 Jeep Grand Cherokee Limited, a higher-end scanner allows for programming remotes, accessing the push start module, and monitoring various systems like ignition, steering, fuel pressure, ABS, and TPIM recalibration. Users can observe real-time data on system activation for components like brakes, lights, stereo, HVAC, steering, ignition, windows, seatbelts, and various sensors and controls.
Even on vehicles with more restrictive software, like a Kia Koup, advanced scanners can still provide valuable access to system data, showing the on/off status of numerous vehicle components. Similarly, on an older salvaged title Toyota Scion TC, a comprehensive scanner grants access to nearly all modules, sensors, and systems, including engine, transmission, fuel, exhaust, brakes, and more, along with real-time monitoring capabilities.
While basic $50-$100 scanners fulfill their purpose of reading and pulling DTCs, MILs, and codes, their limitations become apparent when users need to clear codes or perform more complex diagnostics. Upgrading to a more capable OBD2 scanner, such as those from Cornwell or similar professional brands, can eliminate these hassles and provide deeper insights into vehicle health and performance.
For those seeking more than just basic code reading, exploring professional-grade OBD2 scanners from brands like Cornwell is a worthwhile investment. Whether purchased new or found used at pawn shops, these tools offer enhanced diagnostic capabilities and a more comprehensive understanding of your vehicle’s systems.
