Which vehicles and OBDII setup you need

The NT301 Plus connects through the standard 16-pin OBDII port. It works with 1996 and newer U.S. vehicles, European models from 2001 on, and Asian cars from 2005 on.

It will not work with pre-1996 vehicles. It is also not for Fiat, Alfa, or Lancia, or some Peugeot, Citroen, Ssangyong, Lada, VAZ, UAZ, or GAZ models. If your car uses special protocols, you may need an extra connector cable.

We'd consider this scanner a practical pick for DIYers, home mechanics, and used car shoppers who mainly want engine codes read clearly. Before buying, confirm your car has a 16-pin OBDII port and falls inside the covered year ranges.

What the scanner will not do

The NT301 Plus reads and clears engine codes and tests 12V batteries. It does not read ABS, SRS, or transmission codes, and it cannot handle key programming, oil resets, or battery registration.

It also will not work with tire sensors or airbag codes, and it is limited to 12V batteries only. There is no load test, and the tool has no built-in battery of its own.

What it will not do

Engine and 12V battery diagnostics only, so it covers engine codes and battery health without ABS, SRS, or transmission work.

Difference
$11.53 (13 percent)

At $79.98, it is $11.53 off the typical price over the last 90 days of $91.51, a 13 percent drop. The listing shows 2,760 reviews, but that does not replace checking your car's OBDII port and year range.

What to check before you plug it in

The tool draws power from the OBDII port, so there is no separate power cable to run. Before using the battery check, make sure the battery cable is firmly connected to the OBDII diagnostic cable as noted. Updates are Windows-only, so avoid this if you use Mac or iOS.

When you get a code, fix the issue before clearing it, since clearing first can hide the conditions that set the code.

Who should choose this scanner

Choose the NT301 Plus if you drive a 1996 or newer U.S. vehicle, a 2001 or newer European model, or a 2005 or newer Asian car, and you want both engine code reading and a 12V battery health check from one OBDII device.

Skip it if you need ABS, SRS, transmission, or airbag diagnostics, or if you own a pre-1996 car or one of the excluded makes. Check your vehicle's OBDII port and year range before you buy.
