Nissan and Infiniti owners quickly learn that a basic code reader only scratches the surface. A flashing airbag light, a sticky throttle body that needs a relearn, an ABS fault, or a CVT trouble code all live in manufacturer-specific systems that cheap plug-in readers simply cannot see. To actually fix a Nissan at home you need a scanner that reads beyond the powertrain and can talk back to the car.
We focused on scan tools that handle Nissan body, chassis, and powertrain modules, support live data, and ideally offer bidirectional tests and the all-important electronic throttle relearn. Below are the seven OBD2 scanners that performed best on Nissan and Infiniti models, ranked from the most capable all-rounder down to the smartest budget pick.

1. Autel MaxiCOM MK808S: Best Overall for Nissan
The MaxiCOM MK808S is the scanner we reached for first on every Nissan in the test fleet, and it earned the top spot by being the rare tool that does almost everything well. It pulls full-system diagnostics across the engine, CVT, ABS, airbag, body control module, and more, so a stubborn airbag light or an ABS fault on an Altima or Rogue gets diagnosed instead of guessed at. The bidirectional control is the standout feature here. Being able to actively command a component and watch it respond turns a frustrating intermittent fault into a five-minute test.
Where it really shines for Nissan owners is the service menu. The electronic throttle body relearn, which Nissans frequently need after cleaning or a battery disconnect, is built in and reliable. The honest weakness is the update model. You get a year of free updates included, and after that you will need to renew to keep newer model years and software fully supported. For an owner keeping the same Nissan for years that is a minor cost, but it is worth knowing before you buy.
- Reads and clears codes across all available Nissan modules including ABS, SRS, BCM, and transmission
- Active tests let you command components like fuel pumps, solenoids, and cooling fans
- Includes throttle body relearn, oil reset, EPB, and DPF among 28 plus service resets
Pros: Genuinely covers every system most Nissan and Infiniti owners will ever touch; Large color touchscreen with fast, responsive Android interface; Bidirectional actuation makes it useful for real repair work, not just code reading
Cons: More tool than a casual owner needs for occasional check engine lights; One year of free updates, after which renewals are required to stay current
2. Autel MaxiCheck MX900: Best Bidirectional Value
The MX900 packs a surprising amount of the bigger Autel tools into a compact handheld, and that is exactly why Nissan owners on a careful budget should look at it. It performs full-system scans, runs active tests, and covers more than thirty service functions including the throttle relearn and oil reset that Nissans ask for most. On a Sentra and a Pathfinder it auto-detected the VIN and went straight to the right module list without fuss, which saves real time over manually drilling through menus.
The headline advantage over pricier tools is lifetime free software updates, so the scanner stays useful as Nissan rolls out new models and the database grows. The trade-off is the five-inch screen, which is perfectly readable but feels cramped after using a tablet-sized unit, and the deep menu structure takes a session or two to learn. Once you know where the Nissan-specific functions live, it becomes a tool you trust for serious work.
- All-system diagnostics with active tests for solenoids, relays, and actuators
- Lifetime free software updates keep new Nissan model years supported
- Auto VIN identification jumps straight to the connected Nissan or Infiniti
Pros: Bidirectional control and full-system coverage without the flagship outlay; Lifetime updates are a standout in this segment; Compact handheld body is easy to use in the driver footwell
Cons: Smaller screen than the tablet-style Autel tools; Menu can feel dense for total beginners at first
3. ANCEL FX6000: Best Full-System Tablet
The ANCEL FX6000 gives Nissan owners a true tablet diagnostic experience without climbing into professional shop territory. The eight-inch screen is the reason to choose it, because watching CVT temperature, fuel trims, and sensor data scroll on a large display makes intermittent problems far easier to catch than squinting at a tiny handheld. Across our Nissan test cars it handled all-system scans cleanly and surfaced ABS and airbag codes that simpler readers ignored entirely.
It also carries a healthy list of special functions, including the throttle body relearn and battery registration that modern Nissans benefit from. The honest downside is practicality and polish. The tablet form factor is bulkier to stash in a car, and the update server is noticeably slower than what you get from the top-tier brands, so plan for patience when refreshing the software. For at-home diagnostics where screen real estate matters, it is an excellent value.
- Reads engine, transmission, ABS, SRS, and body systems on Nissan and Infiniti
- Active test and bidirectional support for component-level troubleshooting
- Large 8-inch screen with live data graphing and freeze frame capture
Pros: Big, clear tablet display makes live data and graphs easy to read; Wide special-function list including throttle relearn and battery registration; Strong coverage across older and newer Nissan models
Cons: Bulkier than handheld scanners to store in a glovebox; Update server can be slower than the premium brands
4. Foxwell NT809: Best All-Around Handheld
The Foxwell NT809 sits in the sweet spot for most Nissan owners who want serious capability in a tool that does not overwhelm. Its standout feature is the one-tap auto-scan, which sweeps every module and hands back a clean report of which Nissan systems are throwing codes. On a Rogue with a vague drivability complaint, that single report pointed us at the right system in seconds instead of a guessing game. The seven-inch touchscreen is responsive and the handheld shell feels built to survive garage life.
It covers thirty service functions including the throttle relearn Nissans rely on, plus oil reset, electronic parking brake, and battery management. The realistic weakness is two-fold. The included free updates run out after a period and then require renewal, and the depth of bidirectional control depends on the specific Nissan you plug into, so a few actuator tests available on one model may not appear on another. For everyday diagnostics it remains a very satisfying handhelds to live with.
- Full-system coverage with active tests for actuators and modules
- Auto-scan reports the health of every Nissan system in one pass
- Includes oil reset, EPB, throttle relearn, BMS, and DPF service menus
Pros: Excellent balance of capability and ease of use; Quick auto-scan gives a fast whole-car health snapshot; Responsive seven-inch touchscreen in a durable handheld body
Cons: Free updates are time limited before renewal; Bidirectional coverage varies by specific Nissan model
5. Topdon ArtiDiag500: Best for Beginners
If you have never used a scan tool before and a Nissan dashboard warning light has you nervous, the ArtiDiag500 is the gentlest on-ramp on this list. It reads the four systems that matter to most owners, engine, transmission, ABS, and SRS, and it explains the codes it finds in plain language instead of dumping raw numbers on you. During testing it confidently pulled and cleared an ABS code on a Versa, and the guided flow meant we never had to hunt through confusing submenus.
It also includes lifetime free updates plus practical resets like oil service and steering angle calibration, which is generous for a tool aimed at newcomers. The clear limitation is depth. There is no bidirectional active testing, so you cannot command components to run, and the coverage does not extend into every body control module the way the flagship tools do. For diagnosing the common lights and doing routine resets on a Nissan, though, it is a confidence-building first scanner.
- Reads engine, transmission, ABS, and SRS systems on Nissan vehicles
- Guided menus and clear code definitions for first-time users
- Lifetime free Wi-Fi updates with oil reset and SAS calibration
Pros: Very approachable interface for owners new to diagnostics; Covers the four systems most owners actually need plus key resets; Lifetime updates at this level are a real bonus
Cons: No bidirectional active testing; Coverage stops short of full body-module diagnostics
6. BlueDriver Bluetooth Pro: Best App-Based Scanner
BlueDriver takes a different path by skipping a dedicated screen entirely and turning your phone into the diagnostic display. For Nissan owners that pays off through its enhanced coverage, which reaches manufacturer-specific ABS, airbag, and other module codes that generic Bluetooth dongles miss completely. Plugged into a Maxima, it read enhanced Nissan codes the cheap readers could not, then produced a repair report that ranked the most likely verified fixes for the trouble code, which is genuinely helpful when you are deciding whether to wrench or visit a shop.
The app is polished and the dongle is so small it disappears under the dash. The honest trade-off is that it is a read-and-report tool, not a command tool. There is no bidirectional control and no active testing, so you cannot make the car run a component on demand. It also leans entirely on your phone, meaning a dead battery or a flaky Bluetooth pairing leaves you stuck. For diagnosis and guidance rather than hands-on actuation, it is excellent.
- Pairs with iPhone or Android for full-color diagnostics on your phone
- Enhanced Nissan-specific codes beyond generic powertrain data
- Generates repair reports with verified fixes for the codes it finds
Pros: Uses the screen you already own for a clean, modern interface; Repair reports help less-experienced owners decide next steps; Tiny dongle stores anywhere and travels easily
Cons: No bidirectional control or active component testing; Depends on a charged phone and a stable Bluetooth connection
7. ANCEL BD310: Best Budget Pick
The ANCEL BD310 is the pick for a Nissan owner who mainly wants to know why the check engine light came on and would like a useful gauge display as a bonus. It runs as a standalone wired reader with its own small screen and also pairs to a phone app, and the dashboard mode that streams RPM, speed, and coolant temperature is a neat touch for keeping an eye on a Nissan during a long drive. For reading and clearing engine codes and watching live powertrain data, it does the core job cleanly.
Its limits are clear and you should buy it knowing them. It handles generic powertrain diagnostics only, so it will not read ABS, airbag, or the enhanced Nissan-specific systems that the higher picks on this list cover, and there are no service resets or bidirectional tests at all. That is the nature of a true budget scanner. As a glovebox tool for engine codes and live data, though, it punches above its weight and earns its place as the value option.
- Works as a standalone reader or pairs to the ANCEL phone app
- Reads and clears generic engine codes with live data streaming
- Doubles as a heads-up gauge for RPM, speed, and coolant data
Pros: Affordable entry point that still streams useful live data; Flexible wired plus wireless design with a handy dashboard mode; Compact and simple enough for any Nissan owner to use
Cons: Generic powertrain only, no ABS, SRS, or enhanced Nissan systems; No service resets or bidirectional functions
Frequently Asked Questions
Do I need a Nissan-specific OBD2 scanner or will any scanner work?
Any OBD2 scanner will read generic engine codes on a Nissan because that powertrain layer is standardized across all cars sold since 1996. The difference shows up when you need to reach Nissan systems beyond the engine, such as ABS, airbag, CVT transmission, and the body control module. For those you want a scanner that advertises full-system or enhanced Nissan and Infiniti coverage. Tools like the Autel MK808S, ANCEL FX6000, and Foxwell NT809 read these manufacturer-specific modules, while a basic generic reader will only see powertrain codes and miss the rest.
Can these scanners perform a Nissan throttle body relearn?
Yes, several can, and this is among the most valuable features for Nissan owners. After cleaning the throttle body or disconnecting the battery, many Nissans need an electronic throttle relearn to restore a smooth idle. The Autel MaxiCOM MK808S, Autel MX900, ANCEL FX6000, and Foxwell NT809 all include this service function. Cheaper code readers and app-based tools like BlueDriver and the ANCEL BD310 do not, so if a throttle relearn is on your list, choose one of the full-system tools that lists it in the service menu.
Will an OBD2 scanner read ABS and airbag codes on my Nissan?
Only if the scanner supports full-system or enhanced diagnostics. ABS and SRS airbag modules sit outside the generic powertrain data, so a basic reader cannot see them. On this list the Autel MK808S, MX900, ANCEL FX6000, Foxwell NT809, and Topdon ArtiDiag500 all read ABS and SRS on Nissan vehicles, and BlueDriver reaches them through its enhanced Nissan coverage. If a flashing airbag or ABS light is your reason for buying, avoid the generic-only options and pick a tool that explicitly lists ABS and SRS support.
What is bidirectional control and do I need it for a Nissan?
Bidirectional control, sometimes called active test, lets the scanner command a component to operate so you can confirm whether it works. For example you can tell the fuel pump or a cooling fan to run and watch the result instead of guessing. On a Nissan this turns hard-to-pin-down intermittent faults into quick tests. It is not essential for simply reading and clearing codes, but it is extremely useful for real repairs. The Autel MK808S and MX900, ANCEL FX6000, and Foxwell NT809 offer it, with the exact tests available varying by model.
Do these scanners work on Infiniti as well as Nissan?
Yes. Infiniti is Nissan’s luxury division and shares the same diagnostic architecture, so a scanner with strong Nissan coverage almost always covers Infiniti equally well. The full-system tools here, including the Autel MK808S, ANCEL FX6000, and Foxwell NT809, list Infiniti among their supported makes and read the same body, chassis, and powertrain modules. If you own both a Nissan and an Infiniti, one capable scanner will serve both vehicles, which makes a full-system tool a smart single purchase for a mixed household.
Our Verdict
For Nissan and Infiniti owners who want one tool that does it all, the Autel MaxiCOM MK808S is our top pick thanks to its full-system coverage, reliable throttle relearn, and genuine bidirectional control that makes real repairs possible at home. If you want most of that capability in a more compact package with lifetime updates, the Autel MaxiCheck MX900 is the runner up and the smarter value for many owners. Newcomers should start with the beginner-friendly Topdon ArtiDiag500, while anyone who just needs engine codes and live data can rely on the budget ANCEL BD310.
