This Foxwell NT726 review covers why this 2026 bidirectional scanner stands as the best overall OBD2 scanner for Toyota and Lexus owners who need genuine active test capability alongside full-system diagnostics. The NT726 is a touchscreen bidirectional scanner released in 2026 with a protocol library that addresses the updated Toyota communication architectures deployed since 2022, which is where older bidirectional scanners lose module access on newer Corollas, Camrys, Tacomas, and Tundras. At a competitive mid-range price, it delivers bidirectional active tests across all Toyota system modules, service resets including oil reset, EPB, SAS, and TPMS, and universal OBD2 coverage for all other major makes. I covered the Toyota-specific bidirectional depth, the 2026 protocol update, service function availability, and who benefits most from this scanner.

Foxwell NT726 Review: Quick Verdict
The Foxwell NT726 is the best OBD2 scanner for Toyota owners who want bidirectional active test capability and full system access on a 2026-current protocol base. It covers ECM, TCM, ABS/VSC, SRS, EPS, body, and HVAC modules across Toyota and Lexus, runs active component tests on those systems, and handles service resets. The 2026 release date matters specifically for Toyota: the brand updated its diagnostic protocols starting around 2022, and earlier bidirectional scanners that have not received corresponding database updates lose access to full module communication on those newer vehicles.
My verdict: the NT726 is the right scanner for a Toyota or Lexus owner who regularly works on their own vehicle and needs to do more than read codes. It earns the top recommendation for Toyota in this category. The one trade-off versus some competitors is fewer user reviews given it is a newer product, but its specification and protocol coverage make it the strongest current-market choice for this use case. My roundup of best OBD2 scanners for Toyota covers the full range from basic code readers to bidirectional platforms, with the NT726 in the context of what each tier actually delivers for a Toyota or Lexus owner.
Product Overview
The Foxwell NT726 is a handheld standalone scanner with a touchscreen display and a wired OBD2 connection. It is built to deliver bidirectional diagnostic capability at a mid-range price point, with specific attention to current Toyota and Lexus protocol support. Where the standard Foxwell NT604 Elite gives Toyota owners four-system code access, the NT726 steps that up to full bidirectional active tests across all modules plus a broader service function library. Toyota owners who also service other makes and want bidirectional capability across a broader vehicle range should read my review of the Autel MK808BT Pro, which covers the multi-brand alternative at a similar active test tier.
The scanner uses Wi-Fi for software updates, which means updates are delivered directly to the device rather than requiring a USB connection to a computer. For a current-year scanner like this, keeping the database current is particularly important given how recently the Toyota protocol library was updated.

Setup and First Use
Plug the OBD2 cable into the vehicle’s diagnostic port, power on the scanner, and select the vehicle profile. Auto-VIN reads the vehicle identification automatically on supported vehicles, which is the fastest way to set up a Toyota or Lexus. The touchscreen interface gives access to diagnostics, service functions, and settings through menu navigation that is cleaner than the button-only controls on older Foxwell scanners.
Wi-Fi updates connect the scanner to a network and pull available database updates directly. For a current-year scanner on a vehicle make that recently updated its protocols, staying current through Wi-Fi is more convenient than periodic USB update sessions.
Toyota-Specific Diagnostic Capabilities
Full-System Module Access
The NT726 communicates with all major Toyota and Lexus control modules: ECM (engine control), TCM (transmission), ABS/VSC (antilock brakes and vehicle stability), SRS (airbags), EPS (electric power steering), body control, HVAC, and others depending on the specific model and trim level. An all-system scan runs across all available modules in sequence and presents a complete fault map, which is useful when multiple warning lights are active simultaneously and the priority order of faults is not clear.
The protocol update for 2022 and newer Toyota models is the key specification for this scanner. Toyota revised its internal module communication standards starting with some 2022 model year vehicles, and diagnostic tools without corresponding database updates fail to fully communicate with those modules. The NT726’s 2026 database addresses this, giving it access to fault codes and live data from newer Corolla, Camry, RAV4, Tacoma, and Tundra platforms that some earlier bidirectional tools lose.
Bidirectional Active Tests
Bidirectional active test capability across Toyota and Lexus modules is the NT726’s primary differentiator from basic full-system scanners. Active tests let you command specific components to activate and verify their response without disassembling the system first. On Toyota platforms, active tests include the engine cooling fan relay, fuel injector cut-out tests, oxygen sensor heater activation, idle air control valve, EVAP solenoids, ABS pump motor, and others depending on the specific model year and engine variant. For comparison with a professional multi-brand bidirectional platform, my review of the Autel MaxiSys Elite II Pro covers what active test depth looks like at the next price tier across a full vehicle range.
The practical value of active testing is direct: instead of replacing a cooling fan relay because a code points to it, you can command the relay to cycle and confirm whether it responds before spending money on parts. On a Toyota with an intermittent issue, the ability to stress-test specific components through active commands often reveals faults that do not appear during a static code scan.
Service Functions
The service reset library covers the procedures Toyota and Lexus owners perform as part of regular maintenance. Oil life reset after an oil change, EPB retraction for rear electric parking brake service, SAS (steering angle sensor) calibration after wheel alignment or steering component replacement, and TPMS relearn after tire rotation or sensor replacement are among the core service functions. Toyota-specific procedures on supported models are also accessible through the service menu. Toyota owners who only need ABS and SRS diagnostics with EPB service across multiple brands — without the bidirectional tier — will find the Foxwell NT630 Plus covers those specific functions at a lower price.
Vehicle Compatibility
The NT726 covers all Toyota and Lexus models for enhanced full-system diagnostics and bidirectional capability. Universal OBD2 coverage extends across all other major makes: domestic (GM, Ford, Chrysler), Asian (Honda, Nissan, Mazda, Hyundai, Kia, Subaru), and European (VW, Audi, BMW, Mercedes, Volvo). Bidirectional active test availability for non-Toyota makes varies by model; the Toyota and Lexus platform is where the NT726 delivers the deepest bidirectional coverage for this review’s focus. Honda owners looking for dedicated Honda-specific coverage will find a full breakdown in my reliable Honda OBD2 scanner picks guide, covering Honda TPMS, service resets, and full-system access across Civic, CR-V, and Acura.
Nissan owners using the NT726 for universal OBD2 coverage on Sentra, Altima, Rogue, or Murano will find focused guidance on Xtronic CVT service, CAN-FD compatibility on 2020 and newer models, and ADAS module access in my best OBD2 scanner for Nissan.
Volvo owners using the NT726 across multiple makes will find dedicated coverage guidance for EPB service, SPA-platform diagnostics, and full-system access on XC90, XC60, and S90 in my reliable Volvo OBD2 scanner picks.
The 2026 protocol library is the current database, covering Toyota and Lexus vehicles through the most recent model years available. For owners of 2022 and newer Toyota models, the protocol update is a meaningful advantage over older scanners that have not received equivalent database refreshes.
Live Data and Diagnostic Workflow
Live data is available for all accessible modules with graphing and recording. On Toyota platforms, live data includes ECM parameters such as injection timing, fuel trim values, throttle position, MAF sensor readings, and coolant temperature alongside VSC and ABS sensor data. The touchscreen makes moving through live data streams and selecting individual PIDs for graphing more convenient than button navigation on older handheld scanners.
Freeze frame data captures the conditions at the moment any fault code was stored. For an intermittent Toyota issue that does not reproduce on command, freeze frame gives context about the vehicle state when the fault occurred, which helps narrow down whether the problem appears at operating temperature, under load, or at a specific RPM range.
Hardware and Build Quality
The NT726’s touchscreen form factor is a step up from the 2.8-inch button-navigation displays on Foxwell’s budget line. The larger touchscreen gives more workspace for viewing live data and moving through menus, and the touch input is faster for selecting specific modules during an all-system scan. Build quality reflects the mid-range price: solid construction suitable for regular use in a home garage or a small shop environment. The wired OBD2 connection is durable.
Updates and Total Cost of Ownership
Software updates are delivered via Wi-Fi at no additional cost. As a 2026 product, the NT726’s Toyota database is current, and future updates will add new model coverage as Toyota releases additional vehicles. The Wi-Fi update model keeps the scanner current without the friction of periodic USB sessions. There is no subscription or annual renewal fee.

Who Is This Scanner Best For?
The NT726 is the right scanner for Toyota or Lexus owners who want to do more than read and clear codes. If running an active component test to verify whether a fan relay, injector, or ABS pump motor responds to a command is part of the diagnostic approach, the NT726 covers that on Toyota and Lexus platforms at a price that is significantly below professional tablet-based systems. The 2026 protocol library is the specific reason to choose the NT726 over an older bidirectional scanner for a newer Toyota.
Subaru owners looking for equivalent bidirectional depth on Subaru-specific modules will find the right options in my Subaru-specific OBD2 scanner guide.
It is also a solid choice for a mechanic or advanced DIYer who works on a mix of makes but whose primary vehicle is a Toyota or Lexus, since the universal coverage handles the other makes while the Toyota depth is stronger than what older bidirectional tools in this price range deliver. BMW owners on that same mixed-make bench will want Foxwell’s dedicated BMW scanner, the NT530 Plus for BMW, which applies the same make-specific diagnostic depth to BMW and MINI platforms.
Who Should Skip It?
Skip the NT726 if you only need basic code reading and service resets on a Toyota. The Foxwell NT604 Elite handles those tasks at a lower price. Skip it if you need ECU coding, module programming, or DoIP access for advanced Toyota features. Skip it if the newer-product review count is a concern and you prefer a scanner with a longer track record of user feedback. For buyers who want a deeply established bidirectional scanner with years of Toyota user reviews, the Launch Creader Elite V3.0 is the alternative with a longer proven history at a comparable price.
