The 10 Best Air Bag Scan Tools
Updated by · How we research
Ten scanners that read and clear airbag codes, compared by vehicle coverage, systems and service jobs. The Foxwell NT604 Elite suits most drivers. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki.
A basic code reader can't see airbag faults. The airbag light is run by its own control module, and only scanners built to talk to it can read and clear its codes, and then only on the makes and years they support. This list is for drivers and home mechanics who want the cause before paying a shop.
Editor's Notes
October 26, 2026, by Ezvid Wiki Admin:
The Foxwell NT604 Elite is the new pick for most people. It reads engine, transmission, brake and airbag codes on a wide range of cars and needs no phone or app.
Seven of the nine earlier tools are gone or off target. The Ancel FX3000, Ancel FX6000, OTC Tools 3211, Innova 5100 Pro, Autel MaxiCom and Autel MD802 are no longer sold or have been replaced, and the Ancel VD500 only works on Volkswagen group cars. The Foxwell NT630 Plus stays for anyone doing brake work, and the Autel AL619 stays with a clear warning: its airbag coverage stops short of 2018 models.
New are the BlueDriver for phone users, the Topdon AD600S for late-model cars, and tools from Launch, Ancel, Innova and BLCKTEC that add service jobs or repair reports.
Coverage decided most of this. We compared the systems and model years each maker says its tool supports, looked for the gaps owners keep running into, and read i-CAR and Motor magazine guidance on working around airbags. None of these tools can clear crash data stored after a collision, and the buyer's guide explains why.
April 08, 2020:
While none of these are quite as affordable as a common OBD-II scanner, you don't have to spend an absolute fortune, especially if you aren't planning on doing the most in-depth repairs yourself. The Autel AL619 AutoLink isn't very expensive and for those specifically concerned with SRS system diagnosis, it should get the job done just fine. For a more powerful set of features, the relatively more high-end Autel MD802 is worth a look. The OTC Tools 3211 is noticeably more expensive than the AL619, but less so than the MD802, and like the Autel models it comes from a respected name in automotive tools. The Foxwell NT630 is another straightforward, diagnostic-oriented model, and it's built to hold up to use in the greasy and dirty conditions often found in workshops.
If you're looking for something considerably more versatile, there are still plenty to choose from. The Ancel FX3000 is one of the most reasonably priced touchscreen-enabled choices, while the Autel MaxiCom, which costs considerably more, is suitable for devoted gearheads. The Innova 5160 Pro is especially interesting because not only does it provide realtime data graphing, it allows for a Bluetooth connection with both Android and iOS devices. And if you're willing to deal with a potentially frustrating setup experience, the Ancel FX6000 is another high-powered option, which is also suitable for professional use and comes with a wide range of adapters that allow it to work with quite a few different makes and models.
On the other side of the spectrum, if you don't need such wide-ranging compatibility and want to save a bunch of cash on a tool for your Volkswagen, Audi, or similar vehicle, the Ancel VD500 is straightforward, reliable, and affordable, although it doesn't work with anything from outside the renowned German automotive family.
Special Honors
Autel MaxiSys Autel's MaxiSys tablets are shop-grade scanners with far wider vehicle coverage and two-way control of many modules. They cost several times as much as a handheld and suit professional mechanics or serious hobbyists who work on many different cars. autel.com
NHTSA Recall Lookup Airbag inflator recalls, including the long-running Takata recall, don't show up on any scanner. The National Highway Traffic Safety Administration's free lookup checks a VIN for open safety recalls, and dealers fix recalled parts at no charge. nhtsa.gov
What An Airbag Scanner Can And Can't Do
A scanner tells you where the fault is: a seat-belt buckle switch, an occupant sensor, the clockspring behind the steering wheel, or a loose connector under a seat.
Your car's airbags, seat-belt tensioners and crash sensors report to their own computer, often called the SRS (supplemental restraint system) module. When it finds a fault, it lights the airbag warning lamp, and that light can mean the airbags won't deploy in a crash (Capital One Auto Navigator). Treat it as a safety problem, not a nuisance.
A basic OBD2 reader talks only to the engine computer. Reading airbag codes is an extra feature each maker has to build for each make, model and year, and Innova notes that not every feature works on every car (Innova). Budget readers rarely reach the airbag module at all (OBD Planet).
A scanner tells you where the fault is: a seat-belt buckle switch, an occupant sensor, the clockspring behind the steering wheel, or a loose connector under a seat. Clearing the code only works once that fault is fixed; if it isn't, the light comes back. And if the module stored crash data after a collision, no handheld scanner can erase it, even if no bag went off. That module has to be replaced or sent to a specialist for a reset (YouCanic).
Check Coverage Before You Buy
Coverage matters more than screen size or features. Start with your exact make, model and year, and use the maker's coverage checker if there is one. Year limits are real: Autel says the AL619 reads brake and airbag codes mainly on cars from about 2004 to 2014, a few later ones, and nothing from 2018 on. Ancel FX2000 airbag coverage starts with 2005 models, according to OBD Planet.
Phone-based tools have gaps too. BlueDriver reads airbag codes only on supported makes, and OBD Advisor lists its enhanced coverage by brand group, with model and year exceptions. On a CK5 forum thread, one owner found it read airbag codes on only one of seven GM vehicles.
Newer cars bring two more hurdles. Many late models use a faster data protocol called CAN-FD, and Chrysler, Jeep, Dodge and Ram vehicles from about 2018 on have a security gateway that blocks code clearing unless the tool can log in through an AutoAuth account. If you drive one of those, check for both before you buy.
Finally, decide whether you want service jobs. Brake bleeding after an ABS repair, steering angle resets and parking brake release need a tool that lists them for your car.
Working Safely Around Airbag Parts
Plug a scanner into the OBD2 port under the dash with the ignition on and the engine off, read the codes, and write them down before you clear anything. Most airbag faults trace back to wiring and connectors, and many are under the front seats, where moving a seat can tug a harness loose.
Before you unplug or touch any airbag part, turn the ignition off, disconnect the negative battery cable and wait. The airbag system holds a reserve charge that can fire a bag after the battery is off. Service manuals call for waits from about 90 seconds to several minutes, so use the longest time in your car's manual (Motor magazine; I-CAR). Never probe an airbag connector with a test light or meter.
A scanner can't tell you about a recalled inflator. Defective airbag inflators, such as the Takata units, don't set a fault code, so check your VIN at NHTSA's recall lookup. Recall repairs are free at a dealer. If the light stays on after a crash, or the fault is inside the module itself, a dealer or an airbag specialist is the safer choice.
How we researched this
We looked at 22 scanners, including every tool on the previous version of this list, and read the makers' system lists, service functions and coverage limits for the 10 picks. We used independent coverage notes from OBD Advisor and OBD Planet, airbag safety guidance from I-CAR and Motor magazine, patterns in owner feedback, and recall checks with the U.S. Consumer Product Safety Commission. We found no independent lab tests of airbag scanners.

Frequently asked questions
Can an auto parts store reset my airbag light?
Free code checks at parts stores usually read engine codes only. Airbag codes need a scanner that supports your car's airbag module, so ask first, or use your own scanner and fix the fault before clearing it.
Can I reset the airbag light without a scan tool?
Not reliably. The light stays on while the fault is stored. On some cars it goes out by itself after the repair, but most need a scanner that can clear airbag codes once the cause is fixed.
Does it matter which OBD2 scanner I buy?
Yes. Every OBD2 scanner reads engine codes, but airbag, brake and transmission codes depend on the maker's support for your make, model and year. Check coverage before you buy.
Can a scan tool clear crash data from the airbag module?
No. Once the module stores a crash, ordinary scanners can't erase it, even if no airbag deployed. The module is replaced or sent to a specialist for a reset.
Is the Autel MaxiDiag Elite MD802 still worth buying?
We couldn't find the MD802 sold new. Autel's current handhelds, such as the AL619, cover similar ground for older cars, and newer four-system tools reach more recent models.
