Main Features 

Main Features 

  • User-Friendliness

FOXWELL NT604 is very easy to use. This product is designed for mechanics and car owners looking to identify their car’s fault before fixing it. 

NT604 comes with the latest software usable outside the box. With FOXWELL NT604, you don’t need to waste valuable time downloading the software – you can use it from the get-go!

  • Read And Clear Code

NT604 has made reading and clearing code pretty easy. This scanner helps scan your vehicle for possible errors and troubleshoot identified problems automatically. 

It’s a tool that helps save time, money, and most importantly, numerous unjustifiable visits to a mechanic’s shop whenever you suspect an issue with your car. 

  • Live Data

Another exciting feature of the FOXWELL NT604 is its ability to provide a live data stream. Real-time data shown by NT604 includes engine speed, fuel system status, engine coolant temperature, etc. 

With several displayable options, you only need to choose the parameter you want to show and select “Graph.” Your chosen factors will be displayed in both multi-graph and single graphs, with the option to merge both graphs. 

  • Compatibility

What’s the use of an excellent car scanner if it is strictly limited to just a few vehicles? Although most car scanners are plagued by this, otherwise is the case for the FOXWELL NT604 diagnostic scanner. 

All the features offered by NT604 are compatible with over 60 car models worldwide. This makes it a versatile tool in the hands of car owners and car repairers!

  • ABS

NT604 offers a reliable and accurate diagnosis of ABS faults. The device includes an indicator informing users whenever their vehicle’s ABS develops any fault. Nt604 will identify the causes; after fixing them, the warning sign will go. 

The importance of ABS in your vehicle shouldn’t be underestimated. Early identification and fixing of any fault in your ABS system is a brilliant way to extend the overall lifespan of your car. 

  • SRS

FOXWELL NT604 allows users to thoroughly analyze and detect their vehicles’ airbag systems for possible problems. This includes collision sensors, plug lessening, circuit errors, air springs, etc. With NT604, you can conduct deep analysis and timely detection for your car through fault codes. 

However, these fault codes sometimes stay permanent, causing the warning indicator to flash even after replacing the airbag. In this case, you need the SRS code reader to switch off the lights.

  • AutoVIN

With NT604, you can automatically identify your vehicle perform quick scans, helping your match your vehicle with the appropriate updated software to resolve possible compatibility issues and enhance the overall diagnostic capabilities of the device.

However, note that while the AutoVIN feature is available for most cars, it may take longer to automatically get the VIN code. In this case, simply insert the VIN manually to save you time and stress. 

  • Read Transmission Temperature

Another exciting feature of the FOXWELL NT604 car diagnostic scanner is its ability to read transmission temperature. Transmission temperature is the temperature of your car’s transmission oil. 

The individual live data stream menu included in this product’s design makes it possible to show users the graphical representation of transmission temperature. This way, you can easily and quickly know when it overheats and needs to cool off. 

Advance Features 

Advance Features 

  • ECU Tracking 

ECU is the vehicle’s unit that controls major passive safety features, including automatic emergency braking, airbags, air and fuel management, etc. This unit is famously known as the engine management system’s heart and central controller. 

With the NT604 scanning tool, you can be sure of accurately tracking your car’s fuel supply, fuel injection, air management, ignition, etc., to ensure timely diagnosis and fixes of possible problems. 

  • DPF

DPF are devices used for capturing diesel particulates so they aren’t released into the atmosphere. Under certain conditions, DPFs can get blocked, causing your engine to display a fault code while the car goes into limp-home mode. 

Timely cleaning blocked DPFs would save the entire situation. The DPF tracker feature included in the FOXWELL NT604 car scanner lets users know very quickly when their car’s Diesel Particulate Filters are blocked and need to be cleaned. 

Difference Between FOXWELL NT604 VS. LAUNCH CRP123 OBD2 Scanner

The LAUNCH CRP123 car scanner is yet another professional tool touted as an alternative to FOXWELL NT604. How true is that? Continue reading the comparison below to find out.

While LAUNCH CRP123 may feature professional diagnostic software for multiple car models, FOXWELL NT604 turns the notch up a bit, offering a 4-in-1, comprehensive diagnosis feature, ensuring their users accurately know the status of their car’s ABS, SRS, transmission system, and engine system

The device with the most intuitive user interface is arguable, although, with relatively larger screen size, we can safely say that NT604 offers a better data display. Inclusively, NT604 also provides its users with data in two forms, graph, and text, aiding better understanding.

The lifespan of FOXWELL NT604’s battery is disappointing. However, LAUNCH CRP123 doesn’t use batteries; the OBD2 cable included in its design powers the device. 

NT604’s most advanced features include ECU tracking, AutoVIN, Multilingual functions, SRS tracking, and compatibility with over 60+ car models. LAUNCH CRP123’s most advanced features include compatibility with OBD2 protocol test modes, oxygen sensors and carbon canisters troubleshooting, ergonomic product design, and portability.
