5 Best OBD2 scanners for Subaru – 2025/2026
If you own a Subaru, you already know these cars are tough, but also packed with electronics that don’t always play nice with cheap code readers. Some scanners will only read engine codes, while others can access the AWD system, transmission, airbags, and even perform active tests through Subaru’s own SSM protocol.

My insights after testing 100+ OBD2 tools
I’ve tested literally hundreds of OBD2 scanners, so let me tell you why I find these the best value for money.
Understanding Subaru OBD2 System (Simple Explanation)
Before choosing your scanner, here’s what you need to know about Subaru’s diagnostic system:
Subaru uses the standard OBD2 protocol for engine and emissions — but for full-system access (ABS, AWD, airbags, transmission, etc.), you need tools that support Subaru Select Monitor (SSM) communication.
Quick Breakdown
| Level | What It Can Do | Example Tools |
|---|---|---|
| Basic OBD2 (Global) | Read engine codes, check engine light, live data | Any ELM327 adapter, Ancel JP700 |
| Full-System (SSM-Compatible) | Access AWD, ABS, airbags, transmission, EPB | Mucar 682 / BT200 Max / 892BT |
| Dealer-Level (SSM3 / SSM4) | Full coding, programming, module setup | VXDIAG VCX SE Pro 3-in-1 |
✅ Tip: If your scanner says it supports SSM or “Subaru full-system diagnostics,” that’s what you need for real troubleshooting — not just clearing a Check Engine Light.
