Foxwell NT634 Vs. NT624 Elite Vs. NT630 Plus: What They Share?
All these devices are handheld diagnostic tools that plug into your vehicle’s OBD2 port. They offer broad compatibilities for making basic OBD2 diagnostics like reading trouble codes. While each scanner’s compatibility varies (more on that later), they’re all designed to work with a wide range of manufacturers.
Along with that, all three of these tools have both diagnostic and service functions built-in. They’re all capable of reading codes from the engine, ABS, or SRS systems, as well as reading data from sensor modules related to these systems for a more in-depth diagnosis.
Foxwell NT634 Vs. NT624 Elite Vs. NT630 Plus: What are the Differences?
Design And Specifications
The Foxwell NT630 Plus is the most compact of these three tools, with a slim and lightweight design. It is portable and rugged. Navigation is easy, as well, with a straightforward button layout and an easy to read color LCD screen.
The Foxwell NT634 and the Foxwell NT624 Elite are more extensive in dimensions and screen size. While this makes them less portable, this can also make them easier to read and use and gives you more detailed viewing of sensor readings.
While the buttons’ layout is different on the Foxwell NT634 and NT624 Elite, navigating the menus is the same as with the NT630 Plus. Both include four navigational direction buttons and three function keys for accessing your most often used applications.
Overall Features And Functions
The Foxwell NT630 Plus is an excellent OBD2 scanner with SRS and ABS, and its overall functions all support this emphasis. Along with reading trouble codes and sensor data from the ABS and SRS systems, it can conduct OBD2 diagnostics like I/M readiness, oxygen sensor tests, and reading freeze frame data.
The core functions of the Foxwell NT634 start with a 4-system diagnosis. Not only can you read more information, but you can also do more with it. The data manager function supports downloading and printing data through the PC, and it can read more sensor PIDs from all systems.
For the most core functions, the Foxwell NT624 Elite is what you want. It has an all-system diagnosis, letting you troubleshoot problems with systems like the AC or headlights along with the engine, transmission, etc. It has the same data manager and broad PID support as the Foxwell NT634, too, making it the most comprehensive option for essential functions.
Extra Features/Functions
Foxwell NT630 Plus
As a specialized tool, the Foxwell NT630 Plus has limited extra functions. It offers various useful things you wouldn’t expect for the price, though, including automatic ABS bleeding and manual testing for ABS. You can also use it to calibrate the steering angle (SAS).
The Foxwell NT624 Elite has two reset services: oil light reset, and EPB reset. These are the most common for DIY mechanics and with its all-system diagnosis. You can turn off any dash warning light with this tool.
For service and reset functions, the Foxwell NT634 has the most to offer. It has 11 service functions, including oil light reset, TPMS reset, SAS calibration, and more. You can even use it to relearn gears and code injectors, making it an excellent choice for advanced home mechanics.
Supported Protocols
The Foxwell NT630 Plus and Foxwell NT624 support all standard OBD2 protocols, including CAN networks. With the Foxwell NT624 Elite, you’ll get support for both OBD2 and EOBD protocols used on automobiles made in Europe.
Supported Car Makes
These scan tools will read trouble codes and sensor data from any vehicle compatible with the OBD2 system and a 12-volt battery. When you get into the other systems and reset functions, you begin to see differences in their compatibility.
The ABS/SRS functions of the Foxwell NT630 Plus are for 60+ car makes, with support for SAS calibration for 30+ manufacturers.
For all-system diagnosis, the Foxwell NT624 Elite supports 56 vehicle brands, including common manufacturers like Ford, GM, Volkswagen, and Toyota. The two reset functions may not be supported by all these, though, so you’ll want to check their compatibility before buying it.
Foxwell NT624 Elite
The Foxwell NT634 has the broadest compatibility. Its 4-system diagnosis is available for most OBD2 compatible vehicles (and EOBD vehicles made after 2000). Again, the compatibility of the service functions may vary. For example, an oil reset is available for 50+ brands and EBP for 41 brands, so you’ll want to verify what it offers for your vehicle before buying.
Software And Updates
All three of these scan tools have free lifetime updates through a PC using the FoxAssist update manager. The Foxwell NT624 Elite has the advantage of built-in Wi-Fi that lets you update it straight through the scan tool. NT624 Elite is a perfect option for Mac users since you’ll need a Windows-based PC to update the other two devices.
Recommendation
We love the Foxwell NT630 Plus for beginning home mechanics. It does more than most OBD2 scan tools but is still very affordable and user-friendly, perfect for those just getting into automotive repair.
The Foxwell NT624 Elite is suitable for either advanced home mechanics or traveling repair professionals. Broad compatibility and all-system diagnosis make it a powerful tool for assessing the overall health of any vehicle.
Our top recommendation for advanced DIY mechanics is the Foxwell NT634. While it only has a 4-system diagnosis, this ABS airbag diagnostic tool includes a host of useful reset functions. It’s an appealing choice for anyone who wants to replace their tires, change their oil, or do other maintenance at home.
FAQs
Can the Foxwell NT634 bleed the ABS?
No, ABS bleeding isn’t one of the 11 service functions supported on this tool. The NT630 Plus is the only tool on this list that offers that function.
Will the Foxwell NT634 register a new battery?
Yes, on many vehicles. You can verify whether this is available for your car by contacting the company with your make and model.
Can the Foxwell NT624 Elite show previous history codes?
Yes, you can view all trouble codes for all systems using this tool, including previous codes, pending codes, and permanent codes.
Does the Foxwell NT624 Elite support module activation?
No, unfortunately. Bi-directional control of modules isn’t one of the supported test functions of this tool. Surprisingly, the Foxwell NT630 Plus is the only tool on this list to support “active test” (bi-directional test), albeit only for the ABS.
Does the Foxwell NT630 Plus need any special software before using?
Nope! All 3 of these Foxwell tools are ready to go right out of the box, and you don’t need to register them before you use them.
Can the Foxwell NT630 Plus read and clear all SRS codes or just airbag codes?
The NT630 Plus covers the entire SRS system, including seat belt codes. The only notable exception is that, while it will clear SRS trouble codes to turn off the dash light, it will not erase permanently stored crash data from the airbag system.
