Best OBD2 Scanners for Subaru Owners
October 31, 2026 · 13 min read
Your Subaru’s ABS, VDC or airbag light is on, and the code reader you borrowed says “no codes.” It isn’t broken. It only talks to the engine computer. This guide shows which OBD2 scanner for Subaru reaches the brake, airbag and CVT modules, and which stop at the engine.
Updated — first published
Quick answer
The right OBD2 scanner for Subaru owners reads four systems: engine, ABS, airbag (SRS) and the CVT transmission. A basic code reader sees only engine and emissions codes. For all four plus service resets, get a full-system scanner such as the Autel MaxiCOM MK808S, and check your VIN against the maker’s coverage list first.

LAUNCH CRP123E V2.0 Elite
Covers the four systems that matter, but gives up body modules and active tests.
FOXWELL NT510 Elite for Subaru
Loads Subaru software only, so every menu is about your car and nothing else.
Who this guide is for
This guide is for Subaru owners who want to read their own warning lights before paying a shop. No mechanical background needed.
This is for you if
- Your ABS, VDC, airbag or transmission light is on and a basic reader shows nothing
- You drive a 1996-or-newer Outback, Forester, Crosstrek, Impreza, Legacy, Ascent or WRX
- You want to know what a fault is before you book the dealer
Look elsewhere if
- You need to program keys or recode modules. That is dealer-tool work
- You have one code to read, once. Read about renting an OBD2 scanner vs buying one first
What Subaru-specific access means
Subaru-specific access means the scanner talks to Subaru’s own modules, not just the shared engine computer. Essentially every car sold in the US since the 1996 model year has OBD2 (also written OBD-II), a standard port and code set that California’s Air Resources Board required on essentially all 1996 and later passenger cars. That standard covers emissions, not brakes or airbags.
Everything else sits in Subaru’s own modules. The dealer reads them with the Subaru Select Monitor (SSM), the factory tool. An aftermarket scanner reaches them only if its maker wrote Subaru software for it.
Every make works this way; our guide to OBDeleven and VW-specific scanners covers the Volkswagen version. Look for “full system” or “enhanced” on the box.
ABS, SRS and CVT codes
ABS, SRS and CVT codes are the three Subaru faults a basic reader cannot see. Each lives in its own module.
ABS and VDC. The ABS module stores wheel-speed sensor and pump faults. It also runs VDC (Vehicle Dynamics Control, Subaru’s stability system), so one bad sensor often lights the ABS and VDC lights together.
SRS. SRS (supplemental restraint system) means the airbags, belt tensioners and crash sensors. Generic OBD2 never shows its codes.
CVT. Most current Subarus use a continuously variable transmission (CVT) Subaru calls Lineartronic. Faults that raise emissions set a generic code; many others sit only in the transmission control module (TCM).
Which generic scanners reach them
Four of the five picks reach the ABS, airbag and CVT modules on a Subaru. Watch the “Years covered” column: makers publish coverage by make, so your VIN decides the rest.

What the table does not show
No maker here publishes a year-by-year Subaru list. A “Yes” means the maker lists that system for Subaru, not that every model year works. Run your VIN through the maker’s coverage checker first.
Autel MaxiCOM MK808S — Best overall
The Autel MaxiCOM MK808S earns the top slot because it reads all available systems, not just four, and adds 28+ service functions.

See it on Amazon →How we chose
Every pick was chosen on one test: which Subaru modules its maker says it reads. Everything else came second.
Our selection method
- In October 2026, Cedar Buy compared each maker’s documentation: Autel’s MK808S manual and AL319 page, LAUNCH’s CRP123 series manual, Foxwell’s coverage list and Lemur’s BlueDriver app listing.
- Subaru ABS, SRS and CVT access was weighted most, because a basic reader misses those faults.
- Tools with no published Subaru coverage, or a subscription for enhanced codes, were left out.
- Specifications come from manufacturer documentation. Cedar Buy does not physically test products — see our editorial policy.
What to look for before you buy
The one thing that matters most is whether the scanner lists Subaru for ABS, SRS and transmission. Everything else is secondary.
Subaru listed for ABS, SRS and transmission
Find Subaru by name in the maker’s coverage list, against each system. “Works on all OBD2 cars” only promises engine codes.
Your VIN in the coverage checker
Makers list coverage by make, and a 2012 Outback is not a 2023 Outback. Enter your VIN before ordering.
Active tests, if you do your own repairs
Active tests let the scanner switch a part on to prove it works. Brake and steering jobs need them.
The “supports 10,000 models” number
Ignore it. It says nothing about your Subaru’s airbag module.
Key terms, explained
These terms decide what a scanner can read on a Subaru.
Plain-language definitions
- OBD2 (OBD-II)
- The standard diagnostic port and engine code set on US cars since the 1996 model year. It covers emissions, not brakes or airbags.
- Enhanced codes
- Codes a carmaker stores in its own modules, outside the OBD2 standard. Subaru’s ABS, airbag and many CVT faults are enhanced codes.
- Active test (bidirectional control)
- The scanner sends a command to a part, such as a fan or ABS pump, so you can check that it responds. Code readers cannot do this.
Mistakes that cost people money
The costliest mistake is using an engine-only reader on an ABS or airbag light, seeing “no codes” and assuming the car is fine.
- Trusting “no codes” from a basic readerIt only checked the engine. The ABS or SRS fault is still stored.
- Clearing an airbag code without fixing itAn SRS light means the airbags may not deploy. Read it, fix it, then clear it.
- Buying for “all makes” without checking SubaruCoverage lists vary by make and system. Check Subaru by name.
- Paying for features you will never useKey programming and coding are dealer jobs. Skip tools sold on them.
Frequently asked questions
Will a basic OBD2 code reader work on my Subaru?
Yes, but only for engine and emissions codes. Every US Subaru since the 1996 model year has a standard OBD2 port, so any reader connects. It will not see ABS, VDC or airbag faults, and it misses CVT faults that do not affect emissions. For those, you need a scanner that lists Subaru for enhanced codes.
Can an OBD2 scanner read Subaru CVT codes?
Only partly, unless it has Subaru transmission software. A CVT fault that affects emissions also sets a generic code any reader can see. Many CVT faults are stored only in the transmission control module. To read those, use a scanner whose maker lists Subaru transmission coverage, such as the LAUNCH CRP123E V2.0 Elite or Autel MaxiCOM MK808S.
Does BlueDriver read ABS and airbag codes on a Subaru?
On US-sold Subarus, yes. Lemur Vehicle Monitors lists Subaru enhanced diagnostics as available in the United States, which covers ABS, airbag and transmission codes. On a Subaru sold in another market, BlueDriver reads engine codes only. It does not run service resets or active tests on any car.
Do I need a Subaru-only scanner like the Foxwell NT510 Elite?
Not unless every car you own is a Subaru. A multi-make scanner such as the Autel MaxiCOM MK808S reads the same main Subaru systems and works on your other cars too. A Subaru-only tool keeps menus short, but a second make means loading different software.
So which OBD2 scanner for Subaru should you buy?
Get the Autel MaxiCOM MK808S if you do your own work, or the LAUNCH CRP123E V2.0 Elite to read the lights. Either way, Cedar Buy’s advice is the same: check your VIN first.
