The short path
A basic OBD2 scanner can read the stored trouble code, but the code rarely names the failed part with certainty. A better diagnostic path is code, freeze-frame data, live data, visual inspection, then a targeted test.
When to upgrade
Upgrade from a code reader when you need ABS/SRS coverage, live graphing, service resets, or bidirectional controls. If the problem is intermittent, live data and freeze-frame information matter more than a long list of generic features.
Common mistake
Do not clear the code just to see whether it comes back before recording the code, freeze-frame data, and readiness state.
