🧠 How to choose an OBD2 scanner (what actually matters)
Most people buy an OBD2 tool because a check engine light appears — but scanners are useful far beyond that. The right choice depends on how deep you want to go:
1️⃣ Compatibility (your car + what you want to scan)
Almost all scanners read engine codes, but not all tools read ABS / SRS (airbag) codes. If you want to diagnose braking or airbag warnings, choose a scanner that clearly supports those modules.
2️⃣ Bluetooth vs handheld (phone app vs standalone)
- Bluetooth scanners are great if you want a modern UI, live graphs, and explanations inside the app.
- Handheld scanners are faster for quick checks because you don’t need a phone, pairing, or app setup.
3️⃣ Live data + freeze frame (the “real” diagnostics)
Codes tell you what happened, but live data helps you understand why. Freeze frame is especially helpful because it shows the exact conditions when the fault was detected (RPM, temp, load, etc.).
4️⃣ Clearing codes vs fixing problems
Clearing the light is easy — fixing the cause is what matters. Use the scanner for:
- confirming the issue is gone after repair
- checking readiness monitors before inspection
- spotting recurring patterns over time
