The affordable price and broad vehicle support off the Foxwell NT604 Elite make it an ideal choice for everyday drivers

The Foxwell NT604 Elite can read codes and data from 4 vehicle systems: engine, transmission, airbags (SRS), and anti-lock brakes (ABS). Live data can be viewed as text or in graph form. This gives users a complete picture of their vehicle’s health than what you’d get from a basic OBD2 code reader and also lets you turn off the associated dash warning lights. 

Another useful function of the Foxwell NT604 Elite is its AutoVIN feature, which quickly imports your vehicle’s data, saving you the hassle of typing it in manually. You’ll also get a 12V/24V battery tester free with your purchase of the NT604 Elite, further adding to its value.

We recommend the Foxwell NT614 Elite for beginning DIYers.

The Foxwell NT614 Elite has the same 4-system diagnostics as the NT604. All live data can be graphed, with the option to merge two PID graphs for more in-depth analysis. It also includes two reset functions, oil reset and electronic parking brake (EPB) service, both helpful repair features for DIY mechanics. 

FOXWELL NT664E
FOXWELL All System Scanner NT644E Diagnostic Scan Tool
4.1
The broad diagnostic power and repair functions of the Foxwell NT644E make it the best option for professionals and advanced DIYers.

Of the three tools, the Foxwell NT644E has the most functions and features. It can diagnose all electronic vehicle systems, including the 4 supported by the NT604 and NT614 and the headlights, HVAC system, chassis, TPMS, and other modules. 

There are more reset and maintenance functions on the Foxwell NT644E, as well. It supports 19 total reset functions, including ABS bleeding, DPF regeneration, and advanced features like Injector coding, gear learning, and clutch adaptation. 

Like with the other tools, all data read by the Foxwell NT644E can be graphed, with options to view multiple graphs side-by-side or merge graphs from multiple PIDs into one. You can also save data, played back, and printed through a connected PC. 

Supported Protocols

The Foxwell NT604 Elite supports all 5 OBD2 protocols, including J1850 PWM, J1850 VPW, ISO9141-2, KWP2000 (also known as ISO14230-4), and CAN networks. 

You’ll get this same complete OBD2 protocol support from the Foxwell NT614 Elite and Foxwell NT644E. For older vehicles, the Foxwell NT614 Elite also supports OBD1 diagnostic protocols used on cars and trucks made in 1995 and earlier. 

Conversely, international users will find the protocol support of the Foxwell NT644E more suited to their needs. It supports EOBD protocols, used in vehicles made and sold in Europe, in addition to its OBD2 coverage. 

Supported Vehicle Makes

You can use any of these Foxwell scanners as an OBD2 diagnostic tool with any vehicle that supports OBD2 protocols. You’ll see some limitations in the compatibility for non-OBD2 diagnostics and features, like reading ABS/SRS codes and data or using the oil reset and EPB reset features. 

The Foxwell NT604 Elite supports full 4-system diagnosis for more than 60 vehicle makes from around the world, including popular brands like Ford, GM, BMW, Mazda, Toyota, and many others. 

You’ll get similar 4-system diagnostic support from the Foxwell NT614 Elite. Its reset functions have relatively broad compatibility, as well, with support for more than 40 manufacturers. Keep in mind that it will only support these functions for vehicles made after 1996. It can diagnose older cars and trucks using OBD1 protocols but can’t perform reset functions on them. 

Similarly, the specific vehicle compatibility of the Foxwell NT644E’s 19 reset functions varies between manufacturers. If you want to double-check which of them will work on your vehicle, you can email AmazonSupport@FoxwellTech.com with your make, model, and year. They’ll be able to tell you exactly what the NT644E can do for your vehicle.

FAQs

Will the Foxwell NT604 Elite work with the newest 2020 and 2021 vehicle models?

Yes, as long as they use OBD2 protocols. If the tool doesn’t seem to support your new 2021 vehicle, check to see if there are any recent updates that need to be installed. Tool updates often expand the vehicle coverage, so you’ll likely be able to use this tool with your vehicle after the software is fully up to date. 

What kind of live data does the Foxwell NT604 Elite stream?

The NT604 can show live data from all modules in the supported systems. This includes engine, transmission, ABS, and SRS data, including transmission temperature, engine RPMs, ignition timing, misfire counts, and more. 

Do these tools come with the cables I need for diagnosis and updates?

Yes. All of these tools include both a diagnostic cable and a USB cable to connect them to a device for updates. 

Will the Foxwell NT604 Elite work with a vehicle made in 1995?

No. Vehicles made in that year still used the OBD1 diagnostic protocol, as opposed to the OBD2 protocol supported by the Foxwell NT604. If you need to diagnose a vehicle from 1995 or earlier, you can do so with the Foxwell NT614 Elite.

Can I print diagnostic data using the Foxwell NT614 Elite?

Yes, although you’ll need to do so through the FoxAssist app. Start by downloading the app onto your computer. You can then use the built-in data manager to organized and store your data, or print it through any connected devices. 

Will the Foxwell NT614 Elite calibrate a steering angle sensor?

Unfortunately, no. Steering angle adjustment (SAS) is not one of the repair functions included on this tool. You can do this using the Foxwell NT644E, however, so that’s the tool you’re looking for if you need this feature. 

Does the Foxwell NT644E work with diesel engines?

Yes, it supports diagnostics for many diesel engines and repair functions like DPF regeneration. The only caveat here is that it will only diagnose diesel engines that use OBD2 or EOBD diagnostic protocols. Some heavy trucks with diesel engines aren’t required to use these protocols and may require a different scanner to effectively diagnose and repair. You can find out what diagnostic protocol your vehicle uses in your repair manual if you’re not sure. 

Can the Foxwell NT644E program TPMS?

Unfortunately, no. You can read TPMS data or reset the TPMS system using the Foxwell NT644E, but it doesn’t support programming TPMS. This means you can use it to reset the system after replacing the tires, but won’t be able to adjust the parameters or customize the sensors in the TPMS system.
