If you’re looking for the best Nissan scan tool, it’s easy to get confused by all the options that are out there. It can be difficult to figure out which ones support your vehicle and offer the diagnostic functions you need.
The good news is, we’re here to answer those questions for you! We’ve rounded up our 5 favorite diagnostic tools for Nissan, with a side-by-side comparison so you can see how they differ.
A Nissan scan tool has advantages over more general diagnostic scanners designed for wide vehicle compatibility. You’ll save some money, first of all, since those tools are often made (and priced) for professionals.
In addition, Nissan scan tools support the OBD2 protocols used in the manufacturer’s vehicles. While not every Nissan uses the same protocol, all 5 scan tools below support CAN, KWP, ISO9141, and ISO14230. Many will also diagnose hybrid and electric vehicles, like the Nissan Leaf. Along with that, you’ll be able to view Nissan-specific trouble codes, not just the generic codes applicable to every OBD2-compliant vehicle.
There are two basic design options for diagnostic scanners. Hand-held scanners are compact and come with the diagnostic software built in. You can use them anywhere, without needing access to a Wi-Fi connection, and don’t have to worry about pairing them with your device.
A wireless OBD2 adapter, on the other hand, gives you more flexibility to choose your diagnostic software. Most are also more affordable than hand-held scanners with the same functionality. Their unobtrusive design is more convenient for scanning while you drive, and allows them to perform continuous monitoring.
You’ll see options of both styles reviewed below. Let’s start with a side-by-side comparison of all 5 models so you can see what each one is capable of.

3. OBDLink MX+ OBD2 Bluetooth Scanner
Similar to the Veepeak adapter above, the OBDLink MX+ OBD2 scanner uses Bluetooth to make any device into a Nissan diagnostic scan tool. While it costs more than most OBD2 adapters it’s worth the investment, in our opinion, providing professional-level diagnostics.
Unlike other OBD2 adapters, the OBDLink MX+ comes with OBDwiz and the OBDLink app. You can also use it with dozens of other software programs, like Torque or DashCommand, and it can communicate with Windows, Android, or Mac operating systems.
With the OBDLink MX+, you can quickly diagnose a range of engine issues. The data sampling rate is up to 4 times faster than most OBD2 adapters, and it’s capable of reading multiple parameters simultaneously. It’s reliable, too, so you don’t have to worry about data gaps or broken connections corrupting your readings.
The Enhanced Diagnostics available for Nissan include all 10 modes of OBD2, in addition to live parameters from the anti-lock brakes, airbags, and tire pressure. Using the right app, you’ll get the same diagnostic power you’d find at a dealership.
We appreciate the safety protocols built into the OBDLink MX+, too. The encryption protocols prevent hackers from getting into your vehicle’s data. You can use it for continuous monitoring, too, thanks to the battery drain protection.
