FOXWELL NT604 Elite Review: ABS, SRS & Transmission Scanner

The FOXWELL NT604 Elite is a wired, handheld OBD2 scanner that reads engine, ABS, SRS airbag, and transmission codes in one tool.

Its primary use is diagnosing warning lights beyond the check-engine light, for a driver or DIY owner who wants a clear fault code before deciding on a repair.

Verified Specifications & Buyer Implications

Design & Build Quality

The NT604 Elite is a handheld unit with a 4.3-inch colour screen and large physical buttons. That layout suits gloved hands and a footwell scan better than a touchscreen alone.

According to the manufacturer documentation, the scanner ships with a solid protective case, which matters for a tool kept in a car boot or toolbox.

The wired design is a practical trade-off: a cable cannot run flat mid-scan, yet the buyer must reach the OBD-II port with the tool in hand.

Setup & Ease of Use

• Plug the 16-pin cable into the OBD-II port, usually under the driver’s dashboard.
• Turn the ignition on and let the scanner power up.
• Choose engine, ABS, SRS, or transmission from the menu.
• Use AutoVIN to identify the vehicle, or enter the VIN manually if it does not work.
• Read the code, note its definition from the DTC library, and check live data when needed.
• Clear a code only after the fault has been repaired.

No software download is needed before first use, according to the product documentation, as software ships preloaded.

How This Review Was Researched

Where sources conflicted, the more specific source for this exact variant was preferred, and the 7-inch NT6X4 Elite series was excluded as a different product.

Category-Specific Performance

Four-System Coverage

The main decision factor is system coverage: engine-only readers leave ABS, SRS, and transmission lights unreadable, while this scanner reads all four.

That matters most when the light is not the check-engine light, since ABS, SRS, and transmission warnings need module access.

Coverage still varies by vehicle, so confirm support for your exact make, model, and year before ordering.

Live Data & Graphing

Live data shows sensor values as they change, rather than only a stored code, and graphing makes a pattern easier to spot than a scrolling list.

This helps separate a steady fault from an intermittent one: a sensor that reads normally at idle but drops out under load tells a different story.

Emissions & I/M Readiness

I/M readiness shows whether the vehicle’s emissions monitors have completed their checks, which is the practical question before an emissions test.

It also supports freeze frame, on-board monitor tests, and O2 sensor tests; freeze frame captures engine conditions when a code was set.

Readiness does not guarantee a pass, and a cleared code can reset monitors that need a drive cycle to complete again.

AutoVIN & Code Lookup

AutoVIN reads the vehicle identification number automatically on supported vehicles, removing manual entry and the chance of selecting the wrong model.

The built-in DTC library shows code definitions on the scanner, so no web search is needed beside the car.

AutoVIN may not work on some older vehicles or certain brands; manual entry remains the fallback.

Key Features Explained

Four-System Diagnosis

This feature reads and clears fault codes for engine, ABS, SRS, and transmission modules, and turns off the related warning light once the fault is repaired.

The limit is scope: it covers four systems, not every module in the vehicle.

Live Data Graphing & Playback

Live data can be shown as text or as a graph, including engine speed, coolant temperature, and fuel-system status.

Playback lets a buyer record a stream and review it later, instead of reading a small screen while driving.

Wi-Fi Updates & DTC Library

One-click Wi-Fi updates keep the scanner’s software current without a PC cable, and lifetime free updates mean coverage does not depend on a paid plan.

The DTC library saves time at the car, although a definition is only a starting point, not a confirmed repair.

Real-World Usability & Maintenance

Daily use is simple: plug it in, pick a system, read the code, and check live data when the code alone is unclear.

Storage is straightforward thanks to the protective case; keep the cable coiled loosely and store the scanner away from extreme heat.

Maintenance is mainly software: run the Wi-Fi update occasionally so new coverage reaches the tool before it is needed.

Some documentation states Mac or iOS systems are not supported for updates, so Apple-only buyers should confirm the update route.

Pros & Cons

Common Issues & Fixes

What to Know Before You Buy

Check compatibility first, using your exact year, make, model, and VIN, since module access is specific to each vehicle.

Understand what it cannot do: no oil reset, battery registration, ABS bleeding, throttle relearn, or other service functions, according to the listing.

Crash and collision data in the SRS system cannot be cleared with this tool, although common SRS codes not caused by a crash can be read and cleared.

Do not expect a battery test: the Elite documentation lists diagnostic functions only, despite some listings confusing it with battery-testing FOXWELL models.

Finally, clearing a code is not a repair: a light that returns points to an unfinished repair, not a faulty scanner.

Who Should Consider It / Who Should Look Elsewhere

Alternatives to Consider

Is It Worth It?

The NT604 Elite is worth it for the buyer whose problem sits outside the engine. ABS, SRS, and transmission codes are the reason to pay more than an engine-only reader costs.

For that buyer, the value is avoiding a second tool or a shop visit just to read a warning light.

The trade-off is clear: no service resets and no bidirectional control mean it will not grow into a workshop tool.

Final Verdict

The FOXWELL NT604 Elite suits a DIY owner who wants engine, ABS, SRS, and transmission diagnosis in one wired handheld. Its main strength is four-system coverage without a phone app or subscription.

Its most important limitation is the absence of service resets and bidirectional control. Buyers who need those functions should choose a more advanced scanner instead.

Frequently Asked Questions

Does the FOXWELL NT604 Elite read ABS and SRS codes?

Yes, it reads and clears ABS and SRS codes on supported vehicles. It also covers engine and transmission, so it is not limited to check-engine codes.

Does the NT604 Elite support oil reset or ABS bleeding?

No, it does not support those service functions. The listing states that it does not support oil reset, battery registration, ABS bleeding, throttle relearn, or ABS relearn.

Can the NT604 Elite clear crash data from the airbag system?

No, crash and collision data cannot be cleared. It can read and clear common SRS fault codes not caused by a crash, but crash data is a separate limit.

Does the NT604 Elite need a phone app?

No, it is a wired handheld scanner and does not need a phone app for diagnosis. Wi-Fi is used for updates on this version, while diagnosis uses the OBD-II cable.

Will the NT604 Elite work on my car?

It supports 60+ car brands, but coverage varies by make, model, and year. Check compatibility with your exact vehicle and VIN before buying.

Is the NT604 Elite the same as the NT604?

No, the Elite is the four-system version reviewed here. Do not confuse it with the standard NT604, the NT301 engine-only reader, or the 7-inch NT6X4 Elite series.
