Best OBD2 Scanners That Can Read ABS & Airbag Codes (Budget Picks)
Last Updated on April 15, 2026 by Juraj
Most cheap OBD2 scanners only read engine fault codes which is useless when the ABS light or airbag warning appears. In this guide I tested budget scan tools that go beyond the engine and cover all four critical systems: Engine (ECU), Transmission (TCM), ABS, and Airbag (SRS). These are called 4-system scanners, and they’re a meaningful step up from basic code readers.
