Take a look : Best Sellers in Code Readers & Scan Tools
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.
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 the 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.
5 Best Nissan Scan Tools
The Autel ML529 is one of the best OBD2 scanners for Nissan owners. First, it offers full OBD2 functionality, with all 10 modes and protocols supported. It’s not just a code reader, though it supports that function beautifully, with an AutoVIN function that lets you view manufacturer-specific as well as generic codes.
The enhanced Mode 6 on the ML529 gives you access to more on-board monitor test results. This is in addition to viewing live data in real-time from the monitors and the freeze frame data when any trouble codes were set. All of these together make it a powerful tool for identifying the source of engine troubles.
We also appreciate the user-friendly operation of the Autel ML529. The built-in DTC library gives you code definitions quickly, a very helpful function for those who aren’t car experts. For emissions tests, it offers a one-button I/M readiness hotkey It’s easy to update the software, as well, from both Mac and Windows-based PCs.
