Check your vehicle and the systems you need to scan
The FOXWELL NT604 is a four-system scanner, meaning it goes past basic check-engine codes to read and clear faults for the engine, ABS, SRS and transmission. We'd consider this the practical pick for a home mechanic who wants to see why an airbag or ABS light is on without paying a shop to plug in, because that coverage is what separates it from a cheap code reader that only handles engine faults.
Before buying, confirm your car or light-duty truck uses OBDII. FOXWELL lists coverage for more than 60 car brands and 10,000 vehicles from model years 1996 to 2025, spanning Asian, European and American makes.

What it will not do
A code reader clears a light, it does not fix the underlying problem. The NT604 can turn off an engine, ABS, SRS or transmission warning once the fault is repaired, but fault codes can only be erased after the problem is fixed.
This is a diagnostic tool, not a repair device. It will not replace a trained technician for mechanical work, and it does not promise that clearing a light means your car is safe to drive.
We'd consider this a fault-finding tool, not a fix.
Clearing a code does not repair the cause.
What it costs and how that compares

At $135.96, the NT604 is $27.99 below the typical price of $163.95 over the last 90 days, about 17 percent off. For a four-system scanner with live data and no subscription, that puts it in the range of budget bidirectional tools without the recurring fees some brands charge.
The current price also matches the lowest price recorded for this tool, so if you've been watching it, this is the number to beat.
Set up and connection checks before you buy
The NT604 connects through your car's OBDII port, and FOXWELL says it ships with the latest software loaded, so there's no download marathon before first use. It also uses AutoVIN to pull the vehicle identification number automatically, which saves entering it by hand.
Lifetime updates are included with no subscription fee, no micro SD card and no registration, according to FOXWELL. Check that your vehicle's OBDII port is accessible and that your model year falls within the 1996 to 2025 range before ordering.
Live data, DTC lookup, data playback and printing are supported, so if you want to capture a snapshot for a shop, confirm how you'll print or save it.
Who should pick this up and who should skip it
We recommend the NT604 for the DIY owner or home mechanic who wants engine, ABS, SRS and transmission codes in one tool without paying a subscription or a shop diagnostic fee. The four-system coverage and live data are the practical reasons to choose it over a basic reader.
We'd skip it if you already own a scanner that covers all four systems, or if you need manufacturer-level programming and calibration that this tool does not claim to provide. For routine fault checks on an OBDII vehicle in the covered year range, it fits the job.
Check your model year and OBDII compatibility before you buy.
