Most cheap OBD2 scanners only read engine/emissions codes over the generic protocol — they cannot touch ABS or SRS/airbag, which live in separate modules. To read a lit ABS or airbag light you need a scanner with explicit four-system (or all-system) coverage. Below, five tools that genuinely read ABS and SRS codes, with per-model truth on what each can read, clear, and command. The single most common mistake: buying a Foxwell NT301 or similar engine-only reader and expecting it to clear an airbag light — it physically cannot.

How we picked

How to Choose the Best obd2 scanners

Confirm the module coverage, not just the marketing. 'OBD2 scanner' alone means engine/emissions only. Look for the explicit words 'ABS' and 'SRS' (or 'airbag') AND ideally 'transmission' — that combination is what the industry calls a four-system scanner. All-system tools (like the Autel MK808S) go further and read every module.
Separate 'read' from 'clear.' Every scanner here reads ABS and SRS codes, but clearing an airbag crash-data code is make-dependent — some vehicles latch a hard code that no aftermarket tool can erase until the underlying fault (or deployed airbag) is fixed. Reading the code to diagnose is the realistic expectation; clearing is a bonus that works on many but not all cars.
Decide whether you need bidirectional (active test) control. Bidirectional lets you command a component — cycle the ABS pump to bleed brakes, fire an actuator to isolate a fault. The Autel MK808S and Innova 5610 do this broadly; the Innova 3160RS does ABS bleeding specifically; the Foxwell NT604 Elite and ANCEL FX2000 read/clear only. If you only diagnose lights, skip paying for bidirectional.
Check your specific make and model year against the maker's compatibility lookup before buying. ABS/SRS coverage is deep on GM, Ford, Chrysler, Toyota and Honda but thinner on some European makes and pre-2000 vehicles. A tool that reads ABS on a Silverado may only read engine on an older Audi.
Match the tool to how often you'll use it. A one-time airbag-light diagnosis justifies a budget four-system reader (ANCEL FX2000, Foxwell NT604 Elite). A DIYer doing brake jobs and repairs wants bidirectional and live data (Innova 5610 or Autel MK808S). Buying up one tier usually costs less than a single shop scan fee.
Verify free lifetime updates and support region. Innova and Autel offer ongoing updates and US-based support; cheaper tablets can go stale. Updates matter because ABS/SRS module definitions expand with each model year.

Ranked, best first

Our Top Picks

Systems covered: All systems (engine, ABS, SRS, transmission, TPMS, and more)
Reads ABS codes: Yes (read + clear)
Reads SRS/airbag codes: Yes (read + clear)
Bidirectional / active test: Yes — 3000+ active tests
Live data: Yes, graphing and recording
Service functions: 28+ (Oil, EPB, ABS bleed, SAS, BMS, etc.)
Display: 7-inch touchscreen tablet, Android 11
Vehicle coverage: 200+ brands, 1996 and newer
Price tier: Premium

What we like

Genuine all-system coverage — reads every module, not just the four-system set
Broad bidirectional active tests including ABS bleeding and actuator commands
Tablet interface with AutoVIN/AutoScan identifies the car and scans all modules in one tap
28+ reset/relearn services cover most DIY and semi-pro repair jobs

Worth noting

Most expensive option here — overkill if you only need to read an airbag light
Some advanced services and newer coverage require in-app purchases or FCA SGW authorization
Larger tablet form factor is less pocketable than handheld readers

The most capable tool on this list: it reads and clears ABS and SRS on virtually any 1996+ vehicle and adds thousands of bidirectional tests. Buy it if you do real repairs and want one tool that never leaves you stranded at a module it can't open.

Innova 5610 CarScan Pro

Systems covered: All systems (engine, ABS, SRS, transmission)
Reads ABS codes: Yes (read + clear)
Reads SRS/airbag codes: Yes (read + clear)
Bidirectional / active test: Yes — send commands to ABS pump, injectors, etc.
Live data: Yes — ABS/SRS/engine/trans, graph, record, playback
Service functions: EPB/ABS brake bleed, BMS/battery reset, oil light reset
Display: Handheld with Bluetooth app option
Vehicle coverage: Most 1996-2023+ OBD2 vehicles
Price tier: Mid-to-premium

What we like

True bidirectional control at well below tablet-scanner prices

Small screen and no app; step up to the NT650 Elite for active tests

The best cheap way to read a lit ABS or airbag light. It reads and clears all four systems reliably; it just can't send commands. Buy it if you diagnose warning lights and don't need bidirectional — for that step up to the Foxwell NT650 Elite.

Frequently Asked Questions

Can a regular OBD2 scanner read ABS and airbag codes?

No. A standard OBD2 scanner reads only engine and emissions codes through the generic OBD2 protocol. ABS and SRS/airbag live in separate control modules that the generic protocol does not reach. You need a scanner that explicitly lists 'ABS' and 'SRS' coverage — a four-system tool like the Foxwell NT604 Elite or ANCEL FX2000, or an all-system tool like the Autel MK808S. An engine-only reader such as the Foxwell NT301 cannot see them at all.

Why can my scanner read the ABS code but not clear it?

Some ABS and most SRS/airbag modules latch a 'hard' code when they detect a serious fault or a deployed airbag. Aftermarket scanners can display that code for diagnosis, but the module will refuse to clear it until the underlying fault is physically repaired — the code returns instantly on the next key cycle. This is a safety design, not a scanner defect. Reading the code to pinpoint the fault is the realistic use; clearing works only once the cause is fixed.

What is the difference between a four-system and an all-system scanner?

A four-system scanner reads the four core modules: engine, ABS, SRS/airbag and transmission — that covers most warning lights a driver sees. An all-system scanner (like the Autel MK808S) reads every module on the vehicle, including body control, TPMS, HVAC and more, and typically adds bidirectional active tests. For diagnosing a lit ABS or airbag light, four-system is enough; all-system is for deeper repair work.

Do I need a bidirectional scanner to fix an ABS light?

Not to diagnose it. Any four-system scanner reads the ABS code that tells you what's wrong. You need bidirectional (active test) capability only if the repair itself requires commanding a component — for example, cycling the ABS pump to bleed the brakes after replacing a caliper. The Autel MK808S and Innova 5610 offer broad bidirectional control; the Innova 3160RS adds ABS bleeding specifically.

Which cheap scanner reads both ABS and SRS codes?

The ANCEL FX2000 and Foxwell NT604 Elite are the most affordable tools that reliably read and clear both ABS and SRS/airbag codes across all four core systems. Both are wired handhelds without bidirectional control. If you also want to bleed ABS brakes, step up to the Innova 3160RS; if you want full active tests, the Innova 5610 is the value bidirectional pick.
