TOPDON TopScan Pro OBD2 Scanner at $110.99 for Phone Diagnostics

Which cars and phones this scanner covers

This is a Bluetooth OBD2 scanner, so it plugs into a standard OBD2 port and talks to the TopGuru Pro app on iOS or the TopScan app on Android. Coverage reaches more than 10,000 models from 1996 onward, and CAN-FD support joined by authorized FCA and Nissan Gateway access opens up many late-model vehicles that cheaper dongles cannot touch.

That coverage comes with an asterisk worth reading. Which functions work depends on the model and year, and TOPDON advises confirming compatibility before you buy. Gateway access for FCA and Nissan vehicles also carries its own yearly subscription fee that TOPDON does not collect, so budget for that separately if your car sits behind a restricted gateway.

Our advice is to treat the vehicle year as your first filter. If your car sits in the 1996 to earlier range with a plain OBD2 port, you are squarely in the supported zone, and the deeper features are a bonus rather than the reason to buy.

What it will not do

The scanner reads and clears codes across engine, transmission, ABS and airbag systems, runs live data, performs 13 or more service resets such as oil reset and EPB along with other maintenance functions, and sends active-test commands to parts including fuel injectors and cooling fans, plus windows, doors, wipers, headlights, A/C clutches and coolant pumps.

What it will not do is diagnose a fault for you or make a failing component safe to drive on. A discount on the tool does not verify that any particular part is healthy, and active tests can command components while the car is parked. Confirm a finding against the vehicle's own service information before you order parts.

What to confirm before checkout

You need a standard OBD2 port and a phone with the right app installed, plus a Bluetooth pairing you can keep live while you work. There is no separate screen and no cable tether, so the phone becomes the display.

The money question is the subscription. Advanced features such as bidirectional control and service functions, along with live data and code clearing, are included for one year, after which renewing all of them costs $99.00 per year. Decline, and the free-for-life core set keeps working, covering code reading, I/M readiness, engine inspection and performance tests. Decide which side of that line you need before the first year ends.

TopFix repair guidance, with DTC repair guides, technical service bulletins, DLC location and a warning light library, is unlimited during that free update period, so it is worth using heavily early if you do your own diagnosis. The tool supports 45 languages, which matters if you share the app with someone who works in another one.

Who should buy this scanner

This suits a DIY owner or working technician who wants full-system scans, live data and active tests without buying a dedicated handheld tablet, and who is comfortable running diagnostics from an iPhone or Android phone.

Skip it if your vehicle is outside the confirmed coverage, if you will not renew the advanced feature subscription after year one and those functions are what you came for, or if Gateway access fees on an FCA or Nissan model would push the real cost beyond what you want to spend. Check your car's model, year and port, then check the renewal price, before you commit.
