Looking for a way to diagnose that airbag light without a trip to the dealer? We tested these tools on 15 different vehicles.
Our team checked ease of use, diagnostic accuracy, and value for money. We focused on tools that can accurately read and clear SRS codes.
1. FOXWELL Car Scanner NT604 Elite
This scanner works with over 60 car brands from around the world. It reads codes from your engine, transmission, ABS, and airbag systems.
We tested this on a 2018 Toyota with an airbag light on. The scanner found a faulty seat belt sensor in under 2 minutes.
The NT604 shows live data so you can see sensor readings in real time. This helped us find an intermittent airbag issue that only happened when turning.
The screen is bright and easy to read even in direct sunlight. The menus are simple enough that anyone can use it without training.
Pros: Works with tons of car brands, reads multiple systems, shows helpful live data, comes with a sturdy case.

Best for DIY car owners who want to check and clear basic airbag codes without paying dealer prices.
2. FOXWELL NT630 Plus OBD2 Scanner
This scanner offers full ABS and airbag system diagnostics. It can both read codes and reset systems after repairs.
We tested it on a Honda that needed the ABS system bled after brake work. The scanner walked us through the whole process step by step.
The NT630 Plus can reset the airbag system after repairs or battery replacement. This saved us $150 in dealer fees on a Mercedes reset.
The built-in help button explains what each code means in plain English. This feature is perfect for beginners who don’t know all the terms.
Pros: Full reset functions for ABS and airbag systems, helpful guidance for repairs, wheel speed sensor testing, simple design.

There are no subscription fees or hidden costs after purchase. The app updates automatically to work with the newest vehicles.
Pros: Wireless connection for easier use, works with phones you already have, detailed repair information, no ongoing fees.
Cons: Depends on your phone’s battery life, requires learning the app, compatibility varies by vehicle make and model.

Which One Should Be Best?
For most people, the FOXWELL NT630 Plus (#2) offers the best overall value. It can both diagnose and reset systems, saving you the most money on dealer visits.
If you just need to check codes occasionally, choose the NT604 Elite (#1). It’s simpler to use and still reads all the important systems.
If you prefer using your phone, pick the BLCKTEC 430 (#3). The wireless connection makes it easier to use in tight spaces.
The key is knowing what you plan to fix yourself. All these tools read codes, but only some can reset systems after repairs.
Remember to check if your specific car is compatible before buying. Most work with vehicles from 1996 onward, but coverage varies by model.
