Code Readers & Scan Tools
TOPDON AD500 OBD2 Scanner
A handheld scanner that reads four major systems and handles common maintenance resets with a touchscreen. It does not offer full system coverage or bidirectional tests in the listing.
A small Bluetooth adapter that turns a phone app into a basic engine code reader with low standby draw. It reads standard engine data only, and the app does most of the work.
A focused scanner for Volkswagen Group owners who want ABS, transmission codes and service resets at home. On other brands it is just a basic engine code reader, and no bidirectional tests are offered.
A phone-based adapter for owners who like tweaking vehicle settings as well as reading codes. The ongoing subscription is the downside, and the listing gives no specifics on vehicle coverage.
A tiny dongle-style adapter that works across phone and PC platforms. The listing is contradictory about power and screen size, so treat the hardware details with caution and rely on your app for features.
A good step up from an engine-only reader for DIY owners who also want ABS, airbag and transmission codes. Coverage of those systems varies by vehicle, and screen and warranty details are missing.

GEARWRENCH GWSMARTBT Bi-Directional Scan Tool
A compact bi-directional scanner that runs on a phone or tablet and never asks for a subscription. The listing is light on supported protocols and gives conflicting manufacturer counts.
A phone based bidirectional scanner that tests components, reads all systems and runs a long list of resets with no app subscription. FCA gateway access still needs your own AutoAuth subscription.
A pocket Bluetooth scanner that turns a phone into an all system code reader with repair guides and common service resets. Six special functions are excluded from free lifetime use, so check what stays free.
A tablet-based heavy duty scanner with bidirectional tests, ECU coding and DPF regeneration for truck shops and fleets. Function coverage varies by truck, so confirm before buying.
A capable shop-level scan tablet with active tests, coding support and a long reset list. Functions vary by vehicle and support comes from the seller, not LAUNCH Tech USA.
Operating System
Android 10.0

6300mAh battery

FOXWELL NT201 OBD2 Code Reader
A plug in engine code reader for drivers who want to see why the check engine light is on and whether the car will pass emissions. It does not read brakes, airbags or transmissions.
A pocket-size Bluetooth scanner that adds bidirectional tests and service resets to code reading, driven from a phone app. It has no screen of its own, and the listing says little about which resets suit which brands.
A tiny Bluetooth diagnostic adapter that works with iPhone, Android and Windows apps and reaches Ford and GM private networks for coding. You need a third-party app, as it has no screen or software of its own.
A tablet-style bidirectional scanner with thousands of active tests and dozens of service resets for serious home mechanics and small shops. FCA gateway access and update renewal are extra, and coverage varies by vehicle.
A capable bidirectional scanner for DIY mechanics and small shops who want coding and active tests without update subscriptions. Screen size and warranty are missing, and FCA access needs your own account.
A handheld check engine code reader with live data, freeze frame and code reset on OBDII vehicles. The listing mentions no ABS or airbag coverage and gives an odd power source entry.
A strong choice for BMW, MINI and Rolls-Royce owners who do their own servicing and want dealer-style resets without a subscription. Check your exact model first, since function support differs between cars.
A handheld scan tool that reads engine, ABS, airbag and transmission systems and shows live data on a large screen. Bidirectional tests and update details are not listed, so confirm what it can do on your car.
A capable engine code reader for home mechanics who want plain-text codes, readiness checks and a battery test. It does not read ABS, airbag or transmission faults and skips diesels.
A wired USB diagnostic port adapter built for stable FORScan sessions and module programming, with automatic Ford network switching. You supply the laptop and the diagnostic software.
A BMW and MINI focused handheld scanner that reads all supported systems and handles battery registration, brake and oil resets at home. On other brands it is only a basic engine code reader.
A capable all-system scan tool for owners who want to run actuator tests and service resets without a shop subscription. Wireless pairing and AutoVIN help, though AutoVIN will not read every car.
