3) Foxwell Nt301 Car Code reader

The Foxwell Nt301 Car Code Reader is a worthwhile tool for drivers, which is helping to keep them updated with their vehicle’s health. However, like every other device, it too has some pros and cons.

It continues to provide an on-screen DTC definition, and a DTC lookup library to allow users to determine the reason as to why the check engine light has illuminated.

The device enables you to immediately identify any problems and issues with your vehicle. Unlike other OBDII devices, this one allows you to confirm repairs during a drive cycle.

The device weighs only 10 ounces and its 2.8 inch TFT color screen provides a great and easy visual to the user. Alongside the code reader comes a disk and a USB cable, which is used to connect it to your computer.

The software of the disk can be downloaded easily, working with all Windows software.

People now don’t have to go through the hassle of driving into a repair shop, or a car shop, and pay thousands of dollars for a professional diagnosis and repair.

Another amazing feature in the device is its ability to pull the VIN from the vehicle and find out the fuel type, and other information about the vehicle.

The Nt301 is a recommended necessity for your vehicle as it is an updated version from the basic car OBDII diagnostic scanner with many upgraded distinctive features.

The device has been found to be too complicated by users. The device contains a lot of technical aspects which may confuse the users and make it challenging for them to operate it.

Many users had to take them out to watch tutorials on how to use the device, which proved to be quite time-consuming.

Another user found that the device failed to work on a Lexus model. The USB software and disk failed to be downloaded on a windows laptop, and the support website failed to solve the problem. Contact with the device manufacturers was futile too, as they did not provide any substantial assistance and help. After a few emails, they stopped responding, and the device was still not working

The user guide has failed to meet the expectations of the users. Poor instructions are provided within the guide, which fails to facilitate the drivers using the device to efficiently and effectively operate it.

The device fails to read SRS, ABS or transmission codes that are not stored in the PCM.
