Best Bidirectional Scanners Under $500

You do not need dealer-level pricing for bi-directional active tests. These TOPDON scanners deliver command-and-test capability for home mechanics shopping under $500 — check Amazon for current pricing on each model.

1 Best value full-system: ArtiDiag600 Pro

Service resets, ABS/SRS/transmission access, and bi-directional tests on many models — the ArtiDiag600 Pro is the most recommended sub-$500 all-rounder for multi-brand households.

2 Bluetooth bi-directional: TopScan Lite

All-system Bluetooth scanner with 8 resets, AI assistant, and FCA AutoAuth. Ideal if you prefer diagnosing from your phone.

3 ABS and service focused: AD500 / AD600S

Engine, ABS, SRS, and transmission coverage with oil, SAS, TPMS, and EPB resets. Strong choice when your primary need is maintenance services and module scans.

4 Price vs capability trade-off

Under $500 you get strong bi-directional coverage but not every ECU coding function dealers offer. Verify active test lists for your exact year/make before purchase.
