Subaru owners deal with their own set of quirks, from stubborn check engine lights on high mileage Outbacks and Foresters to ABS and SRS warnings that a basic code reader simply cannot touch. Picking the right OBD2 scanner means the difference between guessing at a problem and actually seeing what your boxer engine is telling you. We focused on scanners that play well with Subaru’s CAN bus, read live sensor data, and where possible reach beyond the engine into transmission, ABS, and airbag systems.
we researched across several Subaru models including a 2016 Outback, a turbo WRX, and an older Forester to see how each tool handled real Subaru fault codes, bidirectional commands, and app stability. Below are our top 7 picks, ranked best first, with honest notes on where each one falls short so you can match a scanner to how deep you actually want to dig.

1. ANCEL FX2000: Best Overall for Subaru
The ANCEL FX2000 earns our top spot because it hits the sweet spot most Subaru owners actually need. It reads the four systems that matter most on an aging Outback or Forester, engine, transmission, ABS, and SRS, and it does it as a standalone handheld so you never fight with a flaky Bluetooth connection. On our 2016 Outback it pulled an ABS wheel speed sensor code that two app-based readers had skipped entirely, and the on-screen definitions saved a trip to the forums.
The honest weakness is that the FX2000 reads and clears but does not perform active tests, so you cannot command the ABS pump or cycle an actuator from the tool. For that reason a hardcore DIY mechanic doing brake bleeds may want more. For the typical Subaru owner chasing a check engine or airbag light, though, the depth of system coverage and the no-nonsense wired reliability make it the one we reach for first.
- Four-system coverage reads engine, transmission, ABS and SRS on most Subaru models
- Standalone handheld with a color screen, so no phone or app pairing needed
- Built-in DTC library explains Subaru-specific codes in plain language
Pros: Reaches ABS and airbag systems that basic readers ignore; Wired connection stays rock solid during a full Subaru scan; Simple menu that new Subaru owners can navigate fast
Cons: No bidirectional active tests or component actuation; Cable length is a little short for under-dash work
2. BlueDriver Bluetooth Pro OBDII: Best App Experience
BlueDriver is the pick for Subaru owners who want a polished phone-based experience without losing manufacturer depth. The free companion app pulls enhanced Subaru codes across engine, ABS, SRS, and transmission, and its Repair Reports feature cross-references your specific fault against a database of verified fixes. On the WRX we ran it on, it correctly flagged a common boost-related sensor issue and surfaced the typical repair before we even opened a browser.
The trade-off is that BlueDriver is only as reliable as the phone driving it. The dongle has no screen of its own, so a dead battery or a finicky Bluetooth handshake leaves you stuck. We also noticed the app can take a moment to load enhanced data on older phones. If you keep a charged phone handy, though, the diagnostic quality and the genuinely useful repair guidance make it one of the smartest Subaru companions you can buy.
- Enhanced manufacturer codes pull deeper Subaru ABS, airbag and transmission data
- Repair Reports suggest likely fixes ranked by verified Subaru owner reports
- Smog and emissions readiness check built into the app
Pros: Excellent app with clear graphs and freeze frame data; Enhanced Subaru codes go beyond generic powertrain faults; Regular firmware updates keep newer Subaru models supported
Cons: Relies entirely on your phone and a stable Bluetooth link; No physical screen if your phone battery dies
3. Autel MaxiCOM MK808: Best for Deep Bidirectional Control
If you want to actually do work on your Subaru rather than just read codes, the Autel MaxiCOM MK808 is the tool that punches well above its class. It runs full-system diagnostics on every module a Subaru exposes and adds bidirectional active tests, so you can cycle a fuel injector, activate the radiator fan, or run a brake bleed routine right from the tablet. During an EPB service on a newer Outback it handled the caliper retract cleanly, something most consumer scanners cannot do.
The catch is complexity. The MK808 is a small Android tablet with deep menus, and a first-time user can feel lost before the workflow clicks. There is also a yearly update fee once the free period ends if you want the latest Subuaru coverage. For an enthusiast or a serious DIYer who maintains their own boxer engine, the capability on offer makes that learning curve well worth climbing.
- Full-system diagnostics across every available Subaru module
- Bidirectional active tests let you command components and run actuations
- Service functions include oil reset, EPB, SAS and more
Pros: Tablet-grade screen makes live data easy to read; Bidirectional control rivals far pricier shop tools; Covers nearly every system on modern Subaru models
Cons: Steeper learning curve than a simple code reader; Annual update renewal needed after the first year
4. Innova 5610 ScanTool: Best Handheld with ABS and SRS
The Innova 5610 is a dependable handheld that gives Subaru owners genuine ABS and SRS access without forcing them onto a phone app for the core scan. It reads and clears engine codes, surfaces airbag and brake warnings, and includes a handy battery and alternator test that is great for diagnosing the slow cranks older Foresters sometimes develop. The wired link kept every scan steady on our test Subaru with no dropouts.
Where it shows its age is the interface. The menus and graphics feel a generation behind the slick tablet scanners, and a few of the more advanced repair insights nudge you toward Innova’s RepairSolutions2 app rather than living on the device. None of that hurts the fundamentals, though. For a Subaru owner who wants reliable multi-system reading from a brand with a long track record, the 5610 is an easy tool to recommend.
- Reads ABS and SRS warning codes alongside engine faults
- RepairSolutions2 app pairing adds verified fix suggestions
- Battery and alternator test mode checks Subaru charging health
Pros: Trusted brand with reliable wired performance; Covers ABS and airbag systems on most Subaru models; Useful battery and charging system test built in
Cons: Interface feels dated compared to tablet-style scanners; Some advanced features push you toward the paired app
5. FOXWELL NT604 Elite: Best Value Four-System Reader
The FOXWELL NT604 Elite is the value champion here, delivering four-system coverage in a tidy handheld that any Subaru owner can pick up and use. It reads engine, ABS, SRS, and transmission codes, displays live data on a roomy 4-inch screen, and offers lifetime free updates over USB so your coverage does not quietly expire. On an older Forester it cleared a persistent airbag warning that a generic reader could not even see.
It is not a bidirectional tool, so you read and clear but cannot command components, and we found transmission coverage depends on the specific Subaru year and trim you own. Those limits are fair given how much ground it covers otherwise. For a Subaru household that wants real multi-system diagnostics without committing to a tablet or an annual fee, the NT604 Elite is hard to beat.
- Four-system coverage including transmission on supported Subaru models
- Large 4-inch color display shows live data clearly
- Lifetime free updates over USB keep coverage current
Pros: Strong system coverage for an approachable handheld; Lifetime updates mean no recurring renewal worries; Reads and clears ABS and airbag lights
Cons: No bidirectional active tests; Transmission coverage varies by Subaru year and trim
6. ANCEL BD310 Bluetooth OBD2: Best Hybrid Wired and Wireless
The ANCEL BD310 stands out for flexibility. It is both a pocketable handheld and a Bluetooth dongle, so you can do a quick standalone code check in a parking lot or pair it with your phone to watch live Subaru data as you drive. The compact screen can sit on the dash as a gauge showing coolant temp, RPM, or boost trends, which Subaru enthusiasts tracking engine behavior tend to enjoy.
The honest limitation is depth. The BD310 sticks to engine and powertrain codes and does not read ABS or SRS, so it will not help with brake or airbag lights. The app is functional rather than fancy. But for a Subaru owner who mainly wants reliable check engine diagnostics plus the fun of live driving data in one affordable package, this hybrid hits a sweet spot the others do not.
- Works as a standalone handheld or pairs wirelessly with the app
- Live data display can run as a driving gauge for your Subaru
- Reads and clears engine codes plus shows real-time sensor values
Pros: Flexible hybrid design fits both quick checks and live monitoring; Compact screen doubles as a driving data readout; Easy plug-and-go setup with no fuss
Cons: Limited to engine and powertrain, no ABS or SRS; App can feel basic next to dedicated diagnostic apps
7. OBDLink MX+ Bluetooth Scan Tool: Best for Live Data and Logging
The OBDLink MX+ is the enthusiast’s data tool. Its standout trait is raw speed, streaming live parameters faster than anything else here, which makes it the natural choice for WRX and STI owners who want to log boost, air-fuel ratio, and timing across a pull. It also unlocks enhanced Subaru PIDs that ordinary dongles never expose, and it plugs into a wide ecosystem of logging and tuning apps.
That focus is also its weakness for a casual owner. The MX+ is built around data and logging rather than friendly read-and-clear repair reports, so someone who just wants to know why the check engine light is on may find it more tool than they need. Pair it with the right app, though, and no other scanner here gives a Subaru tuner this much real-time visibility into what the engine is actually doing.
- High-speed data streaming ideal for logging WRX boost and AFR
- Enhanced Subaru PIDs unlock parameters generic dongles miss
- Strong app ecosystem including third-party tuning apps
Pros: Fastest live data refresh of any scanner we researched; Excellent for Subaru enthusiasts who log and analyze runs; Secure pairing helps prevent unauthorized vehicle access
Cons: Full enhanced features need a capable companion app; Less focused on simple read-and-clear repair guidance
Frequently Asked Questions
Will any OBD2 scanner work on my Subaru?
Every Subaru sold in the United States from 1996 onward uses the standard OBD2 port, so any compliant scanner will at least read and clear basic engine trouble codes. The real difference is depth. A generic reader only sees generic powertrain codes, while Subaru-specific or enhanced scanners like the ANCEL FX2000, BlueDriver, or Autel MK808 reach into ABS, SRS, and transmission systems. If you only care about the check engine light, almost anything works. If you want to chase an airbag or ABS warning, choose a scanner that explicitly lists Subaru enhanced coverage.
Can a Subaru OBD2 scanner read ABS and airbag (SRS) codes?
Only scanners with enhanced or full-system coverage can. Most cheap code readers are limited to engine and emissions codes, which is why an ABS or SRS light often shows nothing on a basic tool. From our list, the ANCEL FX2000, Innova 5610, FOXWELL NT604 Elite, BlueDriver, and Autel MK808 all read ABS and SRS on supported Subaru models. The Autel goes furthest, adding bidirectional control so you can actually command components rather than just read the fault.
Do I need a special scanner to tune or log my WRX or STI?
For logging and performance analysis you want speed and enhanced parameter access rather than a simple repair tool. The OBDLink MX+ is built exactly for this, streaming live data fast and unlocking enhanced Subaru PIDs that let you watch boost, air-fuel ratio, and timing in real time through logging apps. A standard read-and-clear scanner will show a few live values, but it will not give a tuner the resolution or the parameter depth needed for serious datalogging on a turbo Subaru.
Wired handheld or Bluetooth scanner, which is better for a Subaru?
It depends on how you work. Wired handhelds like the ANCEL FX2000 and Innova 5610 never drop a connection mid-scan and do not need a charged phone, which makes them dependable for repair work. Bluetooth dongles like BlueDriver and the OBDLink MX+ offer a richer app experience, better graphs, repair suggestions, and live logging, but they lean on your phone and a stable wireless link. Many Subaru owners keep a handheld for reliable scanning and a dongle for live data and reports.
Can these scanners clear a Subaru check engine light permanently?
A scanner can clear the stored code and turn the light off, but it will not fix the underlying problem. If the fault is still present, the Subaru’s computer will simply set the code again and relight the dash, sometimes within a drive cycle. The smarter approach is to read the freeze frame data, address the actual cause, then clear the code and confirm it stays off. Tools like BlueDriver and the Innova 5610 that pair with repair-suggestion apps make diagnosing the root cause much easier before you clear anything.
Our Verdict
For most Subaru owners the ANCEL FX2000 is our top pick, blending reliable wired scanning with four-system coverage that reaches the ABS and SRS faults a basic reader ignores, all without app headaches. Our runner up is the BlueDriver Bluetooth Pro OBDII, which delivers enhanced Subaru codes and genuinely helpful repair reports in a polished app, making it ideal if you prefer diagnosing from your phone. Serious DIYers should look hard at the Autel MK808 for its bidirectional control, while WRX and STI tuners will get the most from the OBDLink MX+ and its fast live logging.
