Best scanners for ABS and airbag (SRS) codes
Updated November 9, 2026
If your ABS or airbag light is on, a basic OBD2 code reader usually won't tell you why: those faults are stored in separate modules that cheap readers can't talk to. You need a scanner that reads the ABS (anti-lock brake) and SRS (supplemental restraint, or airbag) systems for your make. Here's what to look for, and in-stock scanners whose listings name ABS/SRS or all-system support.

Why your code reader shows nothing
Generic OBD2 code readers read the powertrain codes behind the check-engine light. The ABS and airbag systems have their own control modules, and reading them takes a scanner with manufacturer-level coverage for those systems. That's why a parts-store code read can come back empty while the ABS or airbag light stays on.
Scanners that read these systems usually say ABS and SRS in the product name, or are listed as "all systems" or full-system scanners.
What to check before you buy
Coverage varies by make, model and year, especially for ABS and airbag modules. Check the retailer's vehicle coverage list for your exact car and the systems you need.
If you plan to bleed brakes on a car with ABS, some vehicles need the scanner to cycle the ABS pump. That's a bidirectional function, which basic ABS/SRS code readers don't include. See our guide to bidirectional scan tools if you need it.
Airbag light safety
An airbag warning light can mean the airbags may not deploy in a crash, so get it diagnosed soon. Reading the code is safe, but clearing it doesn't fix the fault, and airbag parts and wiring should be serviced by a qualified technician following the manufacturer's procedure.
An ABS light usually means the anti-lock function is off while normal braking still works. If the red brake warning light is also on, or the pedal feels wrong, stop driving and have the car checked.
Before you buy
- Is your exact make, model and year covered for ABS and SRS?
- Do you also need engine codes and live data (most ABS/SRS scanners include them)?
- Will you bleed ABS brakes? Then you need a bidirectional tool.
- Are software updates free, and for how long?

Questions
Can a regular OBD2 scanner read ABS codes?
Usually not. Basic OBD2 code readers only read engine and emissions codes. You need a scanner that lists ABS (and SRS for airbags) support for your vehicle.
Can I clear an airbag light with a scanner?
A scanner that supports SRS can clear stored airbag codes, but the light comes back if the fault is still there. Because airbags are safety equipment, have the cause diagnosed and repaired properly.
Is it safe to drive with the ABS light on?
Normal brakes usually still work, but the anti-lock function may be off, so stopping on slippery roads can take longer. If the red brake light is also on, or the pedal feels soft, stop driving and have it checked.
