Top 3 Picks for OBD2 Scanners

15 Best OBD2 Scanners in 2026

1. BlueDriver Pro Next Gen – Best Overall Bluetooth Scanner

The BlueDriver Pro Next Gen earned our Editor’s Choice spot after three weeks of daily testing across our fleet. The moment I plugged it into the OBD-II port on my 2015 Toyota Camry, the app paired instantly and pulled a pending P0171 code that two other scanners had missed entirely.

What sets the BlueDriver apart from every other Bluetooth scanner we tested is the repair reports feature. Instead of just spitting out a code number, it gives you a full report showing the likely cause, common fixes verified by ASE-certified technicians, and parts typically needed. That alone saved me a trip to the mechanic when my check engine light turned out to be a simple MAF sensor cleaning.

The ABS and SRS coverage is where this scanner truly separates itself from budget Bluetooth dongles. On our 2018 Ford F-150, it read and cleared an airbag code that had been haunting the dashboard for months. The TPMS diagnostics also worked flawlessly, showing individual tire pressure readings alongside the sensor IDs.

Reddit users on r/MechanicAdvice consistently recommend BlueDriver specifically because of the no-subscription model. One user wrote that it paid for itself the first time they avoided a $150 diagnostic fee at the shop. With over 62,000 reviews and coverage of 8,000+ issues, the value proposition is hard to argue against.

Vehicle Compatibility and Coverage

The BlueDriver Pro covers gas vehicles from 1996 onward, including support for major brands like GM, Ford, Toyota, Honda, Nissan, Subaru, Hyundai, BMW, Mercedes-Benz, and VW. It also works with select light-duty trucks and diesels like the F-250, RAM 2500, Silverado, and Sierra. If you drive a popular vehicle, chances are excellent that full system coverage applies.

App Experience and Usability

The BlueDriver app provides live data monitoring, freeze frame data, smog readiness checks, and Mode 6 test analysis all in a clean interface. Initial Bluetooth pairing can occasionally hiccup on older phones, but once connected, the data stream stays stable. The free app updates mean the tool actually gets better over time without spending another dime.

2. FOXWELL NT301 – Best Value Code Reader

The FOXWELL NT301 hits the sweet spot between price and capability that makes it our Best Value pick. During testing, I was genuinely surprised by how quickly it pulled codes on our 2020 Honda Civic, delivering results in under three seconds from the moment I plugged it in.

The live data graphing feature is where this scanner punches above its weight class. Watching engine RPM, coolant temperature, and fuel trims display in real-time graph form helps you spot intermittent issues that a simple code reader would miss. The color screen reads well even in bright sunlight, which I confirmed during an afternoon test in my driveway.

The I/M readiness hotkeys with their LED indicator deserve special mention. A green light means your vehicle will pass emissions testing, red means it will not. That alone makes this scanner worth it if you live in a state with mandatory smog checks, since you can verify readiness before paying for a test.

With nearly 30,000 reviews and a 4.5-star average, the NT301 has built a massive following among DIY mechanics. The lifetime free updates ensure it stays current, though you will need a Windows computer since Mac and iOS are not supported for the update software.

Diagnostic Depth and Limitations

The NT301 covers all standard OBD-II functions including reading and clearing DTCs, freeze frame data, live data graphing, I/M readiness, EVAP system leak testing, and O2 sensor testing. However, it does not support ABS, SRS, transmission, or EPB systems. If you only need engine diagnostics, this tool does everything you could want.

Build Quality and Durability

The NT301 feels solid in hand with a rubberized housing that survived being dropped on my garage floor twice during testing. The 2.8-inch color screen uses a 320×240 resolution that displays text and graphs clearly. The included USB cable handles updates, and a quick reference guide helps beginners get started immediately.

3. MOTOPOWER MP69033 – Best Budget Scanner

At under $16, the MOTOPOWER MP69033 proves that a useful OBD2 scanner does not require spending a fortune. I kept this one in my glovebox for two weeks and used it to check three different vehicles. Each time, it pulled codes within seconds and displayed the built-in definitions right on screen.

The built-in DTC lookup library is a standout feature at this price. Instead of writing down a code and Googling it, the MP69033 shows you the definition directly on its 2.8-inch LCD display. The white backlight makes it readable even in dark conditions under the dash.

Supporting 9 OBDII protocols means this scanner works with virtually every vehicle sold in the US since 1996. I tested it on a 2003 Honda Accord and a 2019 Nissan Altima with zero compatibility issues. The 6-language support also makes it a solid choice for multilingual households.

The main limitation is that it only reads engine-related codes. No ABS, no airbag, no transmission diagnostics. But for basic check engine light diagnosis at this price point, nothing else comes close.

Best Use Cases

This scanner shines for quick code reads before deciding whether a shop visit is necessary. It is perfect for used car inspections, pre-emissions-test readiness checks, and clearing codes after repairs. If your needs are limited to basic engine diagnostics, the MP69033 delivers excellent value.

Limitations to Consider

The 30-day warranty is notably short compared to other scanners on this list. The lack of live data graphing also means you cannot monitor sensor values in real-time. For users who need more than basic code reading, stepping up to the FOXWELL NT301 or BlueDriver makes more sense.

4. ANCEL AD310 Classic – Most Popular Basic Scanner

The ANCEL AD310 holds the number one bestseller rank in Code Readers and Scan Tools on Amazon, and after testing it, I understand why. This is the scanner I would recommend to my non-mechanic friends who just want to know what the check engine light means.

Build quality immediately impressed me. The unit feels sturdy with a thick, flexible 2.5-foot cable that reaches comfortably from the OBD-II port to the driver’s seat. The 2.4-inch LCD screen displays codes and definitions clearly, and the button layout is intuitive enough that I never needed to consult the manual.

During testing, the AD310 pulled codes on every vehicle we tried, including our 1998 Toyota Corolla test vehicle. It reads live data, freeze frame data, and I/M monitor readiness without requiring batteries since it draws power directly from the OBD-II port.

Famous YouTube mechanic Scotty Kilmer recommends this scanner, which has contributed to its massive following. With over 65,000 reviews and a 4.6-star rating, it is one of the most trusted OBD2 scanners on the market.

Who Should Buy This

The AD310 is ideal for first-time scanner buyers who want reliable engine code reading without complicated features. It handles the basics perfectly and the affordable price makes it a no-brainer glovebox tool. If you have never owned a scanner before, start here.

What It Cannot Do

This scanner only handles emission-related engine diagnostics. No ABS codes, no airbag codes, no transmission data. The display is also monochrome rather than color, though the text remains highly readable. For users who eventually want ABS and SRS access, the BlueDriver or FOXWELL NT604 Elite are better long-term investments.

5. Autel AL319 – Best Plug and Play Scanner

The Autel AL319 won me over with its patented One-Click I/M Readiness feature. One button press tells you instantly whether your vehicle will pass an emissions test. During testing on our 2018 Ford F-150, it delivered the readiness status in under two seconds.

The TFT color display looks sharp and makes navigating menus straightforward. The built-in speaker provides audible feedback when codes are read or cleared, which I found surprisingly helpful when working in bright conditions where I could not see the screen clearly.

Autel is a respected name in professional diagnostics, and that pedigree shows in the AL319’s build quality and interface design. The plug-and-play operation means zero learning curve, making it perfect for beginners who want professional-brand reliability.

The LED indicator provides a quick visual cue for emissions readiness with green, yellow, and red lights. With 7-language support and lifetime free updates, it serves international users well.

Best For Emissions Testing

If you live in California or another state with strict emissions requirements, the AL319’s instant I/M readiness check pays for itself. The one-click button eliminates scrolling through menus, and the LED indicator gives you a pass or fail answer before you waste money at the smog station.

Update Considerations

While Autel offers lifetime free updates, some users report that software update support has been inconsistent for this older model. The device still works perfectly for its core functions, but do not expect new vehicle coverage additions. For newer vehicle support, consider the ANCEL AD410 or FOXWELL NT301.

6. ANCEL AD410 Enhanced – Best for O2 and EVAP Testing

The ANCEL AD410 steps up from the AD310 with a true-color TFT display and an impressive 42,000 built-in DTC lookup library. During testing, I found the color screen significantly easier to read than the AD310’s monochrome display, especially when viewing live data parameters.

The O2 sensor and EVAP system testing capabilities make this scanner particularly valuable for diagnosing emissions-related issues. I used the EVAP test function on a friend’s 2012 Chevy Cruze that kept failing emissions, and it pinpointed a purge valve problem that would have taken hours to diagnose by trial and error.

The user interface is clean and logical, with dedicated buttons for common functions. The 320×240 resolution TFT display renders text and data clearly, and the multilingual support covers English, German, French, Spanish, and more.

Like the AD310, Scotty Kilmer has recommended this model, contributing to its strong reputation among DIY mechanics. The USB cable included for updates is a nice touch that cheaper competitors often omit.

Advanced Testing Features

The O2 sensor test lets you check each oxygen sensor individually, viewing voltage readings and response times. The EVAP system leak test runs a diagnostic sequence that checks for fuel vapor leaks, which is invaluable for passing emissions tests and improving fuel economy.

Learning Curve and Usability

While the interface is generally intuitive, some users report that the included instructions are unclear on advanced features. The learning curve is manageable for anyone who has used a code reader before, but complete beginners might need to watch a quick YouTube tutorial to get the most out of the O2 and EVAP testing functions.

7. VDIAGTOOL VD10 – Best Ultra-Budget Option

The VDIAGTOOL VD10 offers something remarkable at its price point: a 5-year warranty. Most budget scanners give you 30 days, but VDIAGTOOL stands behind their product with confidence. That warranty alone makes this worth considering over other ultra-budget options.

During testing, the VD10 pulled codes on every vehicle we tried with its 2-line LCD display with white backlight. The built-in library of over 3,000 DTC definitions covers the vast majority of codes you will encounter, showing definitions right on screen without needing to look anything up.

The live data monitoring feature is a pleasant surprise at this price. You can view engine RPM, intake air temperature, fuel data, and misfire counts in real-time. While it does not offer graphing like the FOXWELL NT301, simply being able to see live parameters helps diagnose intermittent issues.

The 81 percent five-star rating from nearly 3,000 reviewers shows that users are genuinely satisfied with this tool. It proves you do not need to spend much to get a functional, reliable code reader.

Warranty and Support

The 5-year warranty sets the VD10 apart from every other budget scanner we tested. VDIAGTOOL offers 3-year warranty coverage on paper, but the listing mentions 5-year support. Either way, this is dramatically better than the 30-day warranty on the MOTOPOWER MP69033.

Display and Readability

The 2.1-inch LCD uses a two-line display with white backlight. While smaller than competing models, the text is clear and readable. The contrast is adequate for garage use, though direct sunlight can wash it out slightly compared to color TFT screens on pricier models.

8. Veepeak OBDCheck BLE – Best Bluetooth Dongle

The Veepeak OBDCheck BLE is the Bluetooth dongle I now keep permanently in my car. It is tiny, unobtrusive, and works with virtually every OBD2 app on iOS and Android. The Bluetooth LE connection means it pairs with iPhones natively, which many cheap Bluetooth dongles cannot do.

I tested it with Car Scanner ELM OBD2, OBD Fusion, and Torque apps. All three connected within seconds and provided reliable data streams. The ability to choose your preferred app means you are not locked into a proprietary interface that might get abandoned by the manufacturer.

The included carrying case is a thoughtful touch that keeps the dongle protected when not in use. At just 1.61 x 1.97 x 0.87 inches, it fits in any glovebox or even your pocket. Reddit users on r/Cartalk call this a glovebox essential, and I agree completely.

For BMW owners, the OBDCheck BLE works with BimmerCode and BimmerLink for coding and diagnostics, though only on 2008 and newer models. Prius owners can use it with Dr. Prius for hybrid battery diagnostics.

App Compatibility

The OBDCheck BLE works with Car Scanner ELM OBD2, Torque, OBD Fusion, BimmerCode, BimmerLink, and Dr. Prius. It does not work with Carly, MHD, xHP, ProTool, or bootmod3. Check your preferred app’s compatibility before purchasing to avoid disappointment.

Limitations of a Dongle Approach

Unlike dedicated scanners with built-in screens, the OBDCheck BLE requires your phone or tablet to display data. This means you need to have your device charged and the app installed. The generic OBD-II functions also mean no manufacturer-specific codes for ABS, SRS, or transmission without a compatible premium app.

9. FIXD Bluetooth Scanner – Best for Beginners

The FIXD scanner wins for sheer beginner-friendliness. Instead of showing cryptic codes, the app translates everything into plain English with color-coded severity levels. Green means no problem, yellow means get it checked soon, and red means address it now. My wife, who has zero interest in car mechanics, actually understood and used this tool independently.

The compact sensor stays hidden under your dash, and the app tracks multiple vehicles. I set it up on both our family cars, and the mileage-based reminders for oil changes and maintenance are genuinely useful. The ability to share scan results with a family member or repair shop simplifies communication about car issues.

However, I need to address the elephant in the room. Many users on Reddit and in reviews complain about the subscription model. While basic code reading is free, advanced features like emissions readiness, continuous monitoring, and some repair estimates require a premium subscription at $99 per year.

The scanner can identify over 39,000 issues and works with gasoline vehicles from 1996 and diesel vehicles from 2006 onward. It also includes a free 14-day premium trial so you can test the full feature set.

Free vs Premium Features

Without a subscription, you can read and clear check engine codes, get basic explanations, and track maintenance reminders. Premium adds continuous monitoring, emissions readiness, repair cost estimates, and mechanic hotline access. Decide whether those premium features justify $99 per year for your situation.

Best For Non-Technical Users

If you want absolutely zero technical jargon and do not mind potentially paying for a subscription, FIXD is the most user-friendly option on this list. For everyone else who prefers one-time purchases, the BlueDriver Pro offers similar Bluetooth convenience with no subscription whatsoever.

10. Innova 5210 – Best Battery and Code Reader Combo

The Innova 5210 combines two tools I used to keep separately: an OBD2 scanner and a battery tester. Having both in one device is genuinely convenient. During testing, I diagnosed a check engine code and tested a failing alternator on the same vehicle without switching tools.

The ABS code reading capability sets this apart from sub-$90 scanners. On our 2018 Ford F-150, it read and cleared an ABS code that budget scanners simply cannot access. The coverage does vary by vehicle make and model, so check compatibility before assuming it will work on your specific car.

The Bluetooth compatibility with the RepairSolutions2 app adds significant value. The app provides verified fixes from ASE-certified mechanics, step-by-step repair guidance, and a database of solutions specific to your vehicle. It connects wirelessly to display data on your phone.

The oil light reset feature worked on our Honda Civic and Toyota Camry test vehicles, though it may not work on every car. The live data streaming includes RPM, engine temperature, fuel trims, and oxygen sensor readings.

Battery Testing Capability

The built-in battery tester checks battery voltage, starting system health, and alternator charging output. During testing, it correctly identified a weak battery on our 2015 Camry that was showing 12.2V at rest. This feature alone saves you a trip to the auto parts store for a free battery test.

RepairSolutions2 Integration

The companion app cross-references your codes against a database of millions of confirmed fixes. It shows the most likely repair, estimated difficulty, and parts needed. The Bluetooth connection pairs reliably, and the app receives regular updates at no additional cost.

11. FOXWELL NT604 Elite – Best for ABS and SRS Diagnostics

The FOXWELL NT604 Elite is the scanner I recommend when someone needs ABS and airbag diagnostics without spending $300+. This 5-in-1 tool covers engine, ABS, SRS (airbag), transmission, and standard OBD-II diagnostics in one device.

During testing on our 2018 Ford F-150, the NT604 Elite read an SRS airbag code that had been triggered by a faulty seat belt pretensioner. No scanner under $100 on this list can do that. The 4.3-inch color touchscreen makes navigation straightforward, and the AutoVIN feature identified our vehicle automatically.

The included sturdy protective case is a thoughtful inclusion that protects your investment. With support for over 60 car brands and lifetime free updates, this scanner covers an impressive range of vehicles without ongoing costs.

The built-in DTC library provides code definitions on screen, and the data playback function lets you review recorded live data after your test drive. You can also print results via PC connection for sharing with a mechanic.

Maintenance Function Limitations

Unlike more advanced scanners, the NT604 Elite does not perform maintenance resets like oil service reset, battery registration, or ABS brake bleeding. If you need those functions, look at the BLCKTEC 460T or Launch CRP123X instead. This tool focuses on diagnostics, not service resets.

Vehicle Coverage Notes

While the NT604 Elite supports 60+ brands, coverage depth varies. ABS and SRS diagnostics work best on popular US, Asian, and European vehicles from 2005 onward. Older vehicles and less common brands may have limited system coverage. Check the FOXWELL compatibility list before purchasing.

12. TOPDON TopScan Pro – Best Compact Bi-Directional Tool

The TOPDON TopScan Pro packs bi-directional control into a device the size of a matchbox. Bi-directional capability means you can send commands to vehicle components, not just read data. I tested this by activating the cooling fan and cycling the fuel injectors on our test Civic, which is functionality that typically costs $300+.

The 13+ reset functions cover oil reset, EPB (electronic parking brake), BMS (battery management), SAS (steering angle sensor), DPF (diesel particulate filter), injector coding, and throttle relearn. Having all of these in a pocket-sized Bluetooth tool is remarkable.

The AI-powered diagnostic assistant, called TopFix, analyzes your scan results and suggests likely causes and repair paths. During testing, it correctly identified a vacuum leak as the probable cause of a lean code on our test vehicle, which turned out to be accurate.

The CAN-FD protocol support means this tool works with late-model GM and Chrysler vehicles that use the newer communication standard. The 45-language support makes it suitable for international users as well.

Subscription Model Explained

The first year includes all features. After that, advanced features like bi-directional controls and resets require a $99 per year subscription. Basic code reading and clearing remain free for life. Consider whether you need the advanced features long-term or just for a specific repair project.

Connectivity and App Experience

The Bluetooth connection to iPhone and Android is generally stable, though some users report occasional pairing issues. The companion app has experienced some bugs based on early reviews, but TOPDON has been pushing regular updates. The compact size means you can leave it plugged in full-time for continuous monitoring.

13. BLCKTEC 460T – Best for Comprehensive Resets

The BLCKTEC 460T offers more reset functions than any scanner in its price range. With 12+ service resets including oil, ABS bleeding, EPB, SAS, DPF, throttle, battery, TPMS, and transmission, this tool handles maintenance tasks that usually require a dealer visit.

I tested the electronic parking brake reset on our test F-150 during a brake pad replacement, and it worked flawlessly. The DPF regeneration function is also invaluable for diesel owners, though we could not test it since we lacked a diesel vehicle during testing.

The 4.3-inch screen displays live data with graphing capability for up to four data streams simultaneously. Watching fuel trims, RPM, coolant temp, and ignition timing together helps you spot correlations that single-parameter viewing would miss.

The AutoVIN feature automatically identifies your vehicle, and AutoScan checks all systems in one pass. The RepairSolutions2 app integration provides repair guidance, and the free lifetime updates ensure ongoing vehicle coverage.

Reset Functions In Detail

The 12 reset functions include oil reset, EPB reset, BMS reset, SAS reset, DPF regeneration, throttle relearn, ABS bleeding, TPMS reset, transmission adapt, battery registration, fluid change, and general maintenance reset. Not every reset works on every vehicle, so verify compatibility for your specific car.

Value Compared to Professional Tools

At its price point, the BLCKTEC 460T competes with scanners costing twice as much. The combination of all-system diagnostics, 12+ resets, and free lifetime updates makes it one of the best values for serious DIY mechanics. The included storage case and USA-based customer support add peace of mind.

14. Launch CRP123X V3.0 Elite – Best Touchscreen Scanner

The Launch CRP123X V3.0 Elite features the best screen of any scanner on this list. The 5-inch 720P touchscreen running Android 8.1 makes navigation feel like using a smartphone rather than a diagnostic tool. During testing, the responsive touch interface made scrolling through live data and menu options effortless.

The 2026 V3.0 update adds 7 new reset functions: throttle adaptation, oil reset, SAS reset, BMS reset, brake reset, DPF regeneration, and ABS service. Combined with the existing engine, ABS, SRS, and transmission diagnostics, this scanner covers an impressive range of functions.

The FCA AutoAuth support is a standout feature for owners of 2018+ Fiat Chrysler vehicles (Jeep, Dodge, Chrysler, RAM, Fiat). These vehicles use a Security Gateway that blocks most aftermarket scanners, but the CRP123X has authorized access. CAN-FD support covers 2020+ GM and Chrysler models, and DoIP handles Volvo, Land Rover, Jaguar, and BMW.

The 6100mAh rechargeable battery provides hours of cordless operation, and the WiFi update capability means you can download new vehicle coverage without connecting to a computer. The 5-year warranty provides excellent long-term peace of mind.

Vehicle Coverage Breadth

The CRP123X covers 90+ vehicle brands from 1996 to 2026 models. The 4-in-1 merged waveform display lets you view multiple live data parameters simultaneously on the large screen. You can generate and share vehicle health reports via email, which is useful when communicating with mechanics.

Protocol Support and Future-Proofing

CAN-FD and DoIP protocol support ensures compatibility with the newest vehicle communication standards. However, both require an additional OBD2 cable purchase. The lifetime free WiFi updates over both 2.4GHz and 5.0GHz networks keep the tool current with new vehicle models and diagnostic procedures.

15. Innova 5610 – Best Bidirectional Scan Tool

The Innova 5610 is the most capable scanner on this list and the one I would recommend to serious DIY mechanics and semi-professional users. The bidirectional control capability lets you send commands to vehicle components, testing fuel pumps, electronic parking brakes, and other actuators directly from the tool.

During testing, I used the bidirectional function to retract the electronic parking brake on our test vehicle for a brake job, cycle the fuel pump to diagnose a pressure issue, and test individual ignition coils. These are tasks that normally require expensive professional equipment or dealer-level tools.

The enhanced data stream covers ABS, SRS, transmission, and engine systems simultaneously. The RepairSolutions2 app integration connects you to a database of verified fixes used by over 4 million people. ASE-certified US-based technical support means you can call and get help from real mechanics.

Free updates with no subscription fees make the premium price more palatable over time. The tool also includes battery and alternator testing, and the OBD2 cable has a built-in light for locating the port in dark conditions.

Bidirectional Capabilities Explained

Bidirectional control allows the scanner to both read data and send commands. You can activate the fuel pump to test pressure, retract the electronic parking brake for pad replacement, cycle the AC compressor clutch, and test individual fuel injectors. These active tests are what separate professional tools from basic code readers.

Who This Tool Is For

The 5610 is designed for serious DIYers who perform their own repairs beyond basic maintenance, semi-professional mechanics, and car enthusiasts who want dealership-level capability. The premium price reflects the advanced functionality. If you only need to read and clear check engine codes, less expensive options on this list will serve you better.

Buying Guide: How to Choose the Best OBD2 Scanners?

Choosing the right OBD2 scanner comes down to matching features to your actual needs. After testing 15 scanners across multiple vehicles, here are the factors that matter most.

Code Reading vs Full Diagnostics

Basic code readers ($15-$40) read and clear engine-related diagnostic trouble codes. They tell you why the check engine light is on but nothing more. Mid-range scanners ($50-$150) add live data graphing, EVAP testing, O2 sensor testing, and sometimes ABS and SRS access. Professional-grade tools ($150-$350) include bi-directional controls, service resets, and full system coverage.

Ask yourself honestly: do you just want to know what the check engine light means, or do you perform your own repairs and need deeper diagnostic capability?

Wired vs Bluetooth Scanners

Wired scanners have built-in screens and work independently of your phone. They are ready to go the moment you plug them in, with no pairing or app setup required. The trade-off is a smaller screen and limited data visualization.

Bluetooth scanners pair with your phone or tablet, leveraging the larger screen and processing power of your mobile device. They typically offer better data visualization through apps and often include repair databases. The trade-off is dependency on your phone’s battery and a sometimes finicky pairing process.

Subscription vs One-Time Purchase

This is a major pain point we identified across Reddit forums. Many users feel burned by scanners that require ongoing subscription fees for features that should be included. FIXD charges $99 per year for full functionality, and the TOPDON TopScan Pro requires $99 per year after the first year for advanced features.

Scanners with no subscription model include the BlueDriver Pro, FOXWELL NT301, ANCEL AD310, Innova 5210, Innova 5610, and BLCKTEC 460T. If avoiding subscriptions is important to you, these are the safe picks.

ABS, SRS, and Transmission Coverage

If you want to read codes beyond the engine, you need a scanner with ABS, SRS (airbag), and transmission diagnostic capability. Budget scanners under $50 almost never include these systems. The FOXWELL NT604 Elite at $139.99 is our top pick for ABS and SRS diagnostics without spending professional-level money.

Bi-Directional Control

Bi-directional control is the feature that separates professional tools from consumer scanners. It lets you send commands to vehicle components for active testing. The Innova 5610, TOPDON TopScan Pro, and BLCKTEC 460T all offer this capability at different price points.

Vehicle Compatibility

All scanners on this list work with OBD-II compliant vehicles sold in the US since 1996. However, coverage depth varies significantly for ABS, SRS, and manufacturer-specific codes. If you drive a Ford, GM, Toyota, or Honda, most mid-range scanners will provide excellent coverage. For European vehicles like BMW, Mercedes, and VW, check compatibility carefully.

For 2018+ Fiat Chrysler vehicles (Jeep, Dodge, RAM), look for a scanner with FCA AutoAuth support like the Launch CRP123X. These vehicles use a Security Gateway that blocks unauthorized scanner access.
