How We Chose These Scanners

What we compared

10 scanners, checked against listed specs for clear-code function, systems covered, live data, freeze frame, I/M readiness, connection type, and display or app.

Our 3 scoring criteria

Code Clearing and Reset Ease, Diagnostic Coverage, and Ease of Use. Every product is scored on the same three criteria, out of 5.

How ratings work

Scores are editorial ratings based on listed specifications, not lab or hands-on test results. No test period is claimed, and no outside expert was consulted.

What we cut — and why

Generic ELM327 clones were cut for inconsistent pairing and clearing, and workshop tablets were cut because they are overkill for clearing codes.

What to Look for When Buying an OBD2 Scanner to Clear Codes

Clearing a code is easy. Clearing the right code, after reading it properly, is the part that matters. These four factors decide whether a scanner helps you or just turns a light off for a day.

1. What Codes It Can Actually Clear

Every scanner here clears engine codes, but only some clear ABS, airbag, transmission, or TPMS codes. Check the systems list before you buy, not the headline. If your ABS or airbag light is on, an engine-only reader will read the engine and leave that light untouched. Match the scanner to the warning light you actually have.

Common mistake: Buying an engine-only reader to clear an ABS light. Learn more about clear codes without fixing the problem before you clear anything.

2. Vehicle Compatibility and Coverage

Look for all five OBD2 protocols, CAN support, and 1996-and-newer coverage for US cars. Enhanced coverage varies by make, model, and year, so a scanner that clears ABS codes on one car may not do it on another. Check the maker’s compatibility list for your exact car before ordering, especially for European or diesel models.

Common mistake: Assuming “works on all cars” means every system on your car. It usually means generic engine codes only.

3. Live Data, Freeze Frame, and Readiness Checks

A code number alone rarely tells you what failed. Live data shows sensor readings while the engine runs, freeze frame captures conditions when the fault set, and I/M readiness shows whether monitors are ready for an emissions test. These three features turn clearing into diagnosing, and they are worth paying for if you fix your own car.

Pro tip: Record the code and freeze frame before you clear anything. Once cleared, that snapshot is gone, and so is your best clue.

4. Handheld vs Bluetooth App, and Updates

Handheld scanners work without a phone, charge, or app, and they are faster in a cold garage. Bluetooth adapters give you a bigger phone screen, saved reports, and plain-English repair hints, but they need a charged phone and a stable app. Either way, check whether updates and full features need a yearly subscription, because some scanners lock live data or clearing behind one after the first year.

Best Overall

FOXWELL NT301 OBD2 Scanner — Fast, Simple Engine-Code Clearing

★ 4.9/5
Best for: Drivers who want a handheld that reads and clears engine codes fast

If your check engine light just came on and you want it read and cleared without a phone, reach for this scanner first. It plugs into the OBD2 port, powers itself from the car, and puts read, clear, live data, freeze frame, and I/M readiness on a 2.8-inch colour screen. Its built-in DTC library explains codes in plain words, so you are not guessing from a bare number. It covers all 10 OBD2 modes on 1996 and newer cars. The trade-off is clear: it clears engine codes only, not ABS or airbag codes.

BlueDriver Bluetooth Pro OBD2 Scan Tool
#2
Best App-Based

BlueDriver Bluetooth Pro OBD2 Scan Tool — Phone Diagnostics, Deeper Coverage

★ 4.8/5
Best for: Drivers who prefer a phone screen and saved repair reports

If you would rather read codes on your phone than on a small handheld screen, BlueDriver is the clearest app-based choice here. The small adapter plugs into the OBD2 port, pairs by Bluetooth, and turns your phone into a scanner that reads and clears codes, shows freeze frame and live data, checks smog readiness, and shows Mode 6 results. On supported vehicles it also covers ABS, airbag, TPMS, and transmission codes, which most basic readers cannot touch. There is no subscription for the core app, but coverage still varies by vehicle, so check your car first.

What we loved
  • ABS, SRS, TPMS, transmission coverage
  • Large phone screen, saved reports
  • Mode 6 and freeze frame included
  • No subscription for core app

Best Budget

Autel AutoLink AL519 OBD2 Scanner — Solid Handheld, Sensible Value

★ 4.8/5
Best for: Everyday drivers who want a reliable handheld without extra systems

If you want a dependable handheld and do not need ABS or airbag coverage, the AL519 is the sensible pick in this list. It reads and clears engine codes, shows live data and freeze frame, checks I/M readiness, and looks up code definitions on a clear colour display. It is powered by the car, so there is no battery to charge and no app to open. The menus are simple enough for a first-time user, yet the live-data view still helps when a code keeps returning. Its limit is scope: engine and emissions only, so choose a four-system scanner for other warning lights.

What we loved
  • Simple menus, fast code clearing
  • Live data and freeze frame included
  • Car-powered, no charging needed
  • Built-in code lookup and readiness
What could be better
  • Engine and emissions codes only
  • No ABS, SRS, or transmission coverage
  • Smaller screen than tablet scanners

Innova 5610 Bidirectional OBD2 Scanner
#4
Best Advanced DIY

Innova 5610 Bidirectional OBD2 Scanner — Clear Codes Across More Systems

★ 4.7/5
Best for: DIYers who clear codes beyond the engine and want service functions

If you fix your own car and your warning lights are not limited to the engine, the Innova 5610 earns its place here. It reads and clears codes across engine, transmission, ABS, and airbag systems on supported vehicles, and it adds bidirectional tests and service functions that basic readers do not offer. The larger screen and guided menus help you move from a code to a likely cause, with live data and freeze frame alongside. It is bigger and more involved than a simple handheld, so it suits a confident DIYer rather than someone who only wants a quick clear.

What we loved
  • Engine, ABS, SRS, transmission coverage
  • Bidirectional tests and service functions
  • Guided menus and larger screen
  • Live data and freeze frame included
What could be better
  • Larger and heavier than basic readers
  • Coverage varies by make and year
  • More menus to learn at first

OBDLink MX+ OBD2 Scanner
#5
Best Bluetooth Adapter

OBDLink MX+ OBD2 Scanner — Fast Bluetooth for iOS, Android, and Windows

★ 4.7/5
Best for: Drivers who want one adapter for phone, tablet, and laptop apps

If you already use diagnostic apps and want an adapter that keeps up, the OBDLink MX+ is the most flexible Bluetooth pick here. It pairs by Bluetooth, works with iOS, Android, and Windows, and supports third-party apps as well as its own, so you are not locked to one screen. It reads and clears codes, shows live data and freeze frame, and supports enhanced manufacturer add-ons on supported vehicles. Its speed helps when you are watching live data while driving. The trade-off is that the app, not the adapter, decides how clear the repair guidance feels.

What we loved
  • Works with iOS, Android, Windows
  • Fast live-data response
  • Third-party apps supported
  • Enhanced add-ons on supported cars
What could be better
  • App quality varies by app
  • No built-in screen or buttons

Best Four-System

FOXWELL NT604 Elite OBD2 Scanner — Four Systems, One Handheld

★ 4.7/5
Best for: Drivers with engine, ABS, airbag, or transmission lights

If more than one warning light is on, a four-system handheld saves you from buying a second tool. The NT604 Elite reads and clears codes from the engine, transmission, ABS, and airbag systems, and it shows live data with graphing, plus AutoVIN to identify the vehicle quickly. Its 4.3-inch colour screen is easy to read in a garage, and lifetime free Wi-Fi updates keep its coverage current without a subscription. It does not offer bidirectional tests or service resets, so it is a clearing and reading tool, not a workshop tablet.

What we loved
  • Four systems in one handheld
  • Live-data graphing and AutoVIN
  • Lifetime free Wi-Fi updates
  • Clear 4.3-inch colour screen
What could be better
  • No bidirectional tests or resets
  • No battery test or key coding

#7
Best for ABS/SRS

Autel AutoLink AL619 OBD2 Scanner — ABS and Airbag Codes, Handheld Simple

★ 4.6/5
Best for: Drivers with ABS or airbag lights who want a simple handheld

If an ABS or airbag light is your problem, the AL619 is the most direct handheld answer in this list. It reads and clears ABS and SRS codes as well as engine codes, shows live data and freeze frame, and checks I/M readiness on a clear colour screen. It is car-powered and menu-driven, so you can move from reading a code to clearing it without a phone or app. It does not cover transmission codes or offer bidirectional tests, so it is best when ABS, airbag, and engine lights are the ones you need to clear.

What we loved
  • ABS, SRS, and engine coverage
  • Live data and freeze frame included
  • Simple menus, no app needed
  • Car-powered handheld design
What could be better

LAUNCH CR529 OBD2 Scanner
#8
Best Simple Clearer

LAUNCH CR529 OBD2 Scanner — One-Button Clearing for Beginners

★ 4.6/5
Best for: Beginners who want the simplest way to clear an engine code

If you have never used a scanner before, the CR529 keeps the job short. It plugs in, powers itself from the car, and shows codes, live data, and I/M readiness on a 2.8-inch colour screen, with a one-button shortcut to clear codes. The menus use plain language, and the built-in code lookup helps you understand what the code means before you erase it. It is an engine-only reader, so it will not clear ABS, airbag, or transmission codes. For a first scanner that only needs to handle a check engine light, that focus is a strength, not a flaw.

What we loved
  • One-button code clearing shortcut
  • Plain-language menus and code lookup
  • Clear 2.8-inch colour screen
  • No phone, app, or charging needed
What could be better
  • Engine codes only, no ABS/SRS
  • No live-data graphing

#9

★ 4.5/5
Best for: Budget buyers who want phone-based code clearing

If you want the cheapest way to clear codes from your phone, the Veepeak OBDCheck BLE+ is the budget Bluetooth pick here. The small adapter plugs into the OBD2 port, pairs by Bluetooth Low Energy with iOS and Android, and works with third-party apps to read and clear engine codes, show live data, and check readiness. It is easy to leave plugged in for occasional checks, and it costs far less than a full handheld. Its limits are clear: engine codes only, and the app you choose decides how helpful the results feel.

What we loved
  • Low-cost Bluetooth clearing
  • Works with iOS and Android
  • Third-party apps supported
  • Small, easy to leave plugged in

Best Basic Reader

ANCEL AD310 Classic Enhanced OBD2 Scanner — Basic Clearing, Lowest Fuss

★ 4.5/5
Best for: Drivers who only need to read and clear basic engine codes

If you only need to read a check engine code, clear it after a simple fix, and check emissions readiness, the ANCEL AD310 does that job with the least fuss. It plugs into the OBD2 port, powers itself from the car, and shows stored, pending, and historic codes plus freeze frame and I/M readiness on a small screen. It supports all five OBD2 protocols, so it works across most 1996 and newer cars. It has no live-data graphing and no ABS or airbag coverage, so it is the right pick only when basic engine clearing is enough.

What we loved
  • Very simple, fast to use
  • Reads stored, pending, historic codes
  • Freeze frame and readiness included
  • Supports all five OBD2 protocols
What could be better

Who These Scanners Are NOT For

These scanners are built to read and clear codes. They are not workshop tools, and they will not fix a fault by themselves.

If you need ECU programming, coding, or key programming: These scanners do not do that work. You need a professional tablet or a dealer-level tool, not a code reader.

They are also the wrong pick if you need to clear a permanent code without a repair. Permanent codes clear only after the car completes its own drive cycles and confirms the fault is gone. Clearing also resets readiness monitors, so learn how clearing codes resets readiness monitors before an emissions test.

Common Mistakes to Avoid

Most clearing problems come from rushing the first scan, not from the scanner itself.

Mistake 1: Clearing before recording the code — You lose the code and freeze frame, so diagnosis gets harder. Write down every code first, then clear.
Mistake 2: Clearing right before an emissions test — Clearing resets readiness monitors to not ready, which can fail the test. Learn about clearing codes before an emissions test, then drive until monitors complete.
Mistake 3: Clearing the same code again and again — A returning code means the fault is still there. Fix the cause, clear once, then scan again after a drive cycle.
Mistake 4: Assuming a cleared code is hidden — A scan can still show that monitors are incomplete or that a code was recently cleared. A scanner can detect a recently cleared code, so do not clear codes to hide a fault when buying or selling a car.

Frequently Asked Questions About OBD2 Scanners That Clear Codes

Can an OBD2 scanner clear codes?

Yes, an OBD2 scanner can clear stored and pending codes, and it turns the check engine light off when the clear succeeds. It cannot erase permanent codes by itself, because those clear only after the car runs its own tests and confirms the repair. Always read and record the code and freeze frame before clearing, so you keep the clues you need if the fault returns.

Will a code come back after clearing it?

Yes, a code usually comes back if the underlying fault is still present, because clearing only erases the stored warning. The car re-runs its diagnostic test on the next drive cycles, and if it finds the same fault, it sets the code again. A code that stays away after a repair and a full drive cycle is a good sign the fix worked.

Does clearing codes reset the check engine light?

Yes, clearing codes normally turns the check engine light off right away, because the stored code that triggered it is erased. The light returns if the fault is still present and the car detects it again. To understand the timing, read how clearing codes and the check engine light work together before you clear a code you have not diagnosed.

Does clearing codes reset readiness monitors?

Yes, clearing codes resets readiness monitors to incomplete, so the car must complete its self-tests again before they show ready. That is why you should not clear codes just before an emissions test, where incomplete monitors can mean a failure. Drive through normal city and highway cycles, then scan again to confirm the monitors are ready.

Can any OBD2 scanner clear ABS and airbag codes?

No, most basic scanners clear engine codes only and cannot clear ABS or airbag codes. You need a multi-system scanner that lists ABS and SRS coverage for your make, model, and year. Check that coverage before you buy, because a scanner that clears ABS codes on one car may not do it on another.

Do I need a phone app or a handheld scanner to clear codes?

No, either one can clear codes, so choose the form you will actually use. A handheld works without a phone, app, or charge, and it is faster in a garage. A Bluetooth adapter gives you a bigger phone screen, saved reports, and repair hints, but it needs a charged phone and a stable app to work well.

Our Final Verdict

Most drivers only need fast, honest engine-code clearing, and the NT301 does that best with no phone or subscription. If you need wider coverage, BlueDriver is the app-based step up, while the AL519 is the simple handheld for engine codes alone.

Best Overall

FOXWELL NT301 OBD2 Scanner

The NT301 is the right choice if you want engine codes read and cleared fast, with live data and readiness checks on a clear handheld screen. It needs no phone or subscription, though it clears engine codes only.
