Not all trouble codes are included under the OBD2 diagnostics. For non-OBDII systems like the anti-lock brakes (ABS) and airbags (SRS), an ABS/SRS OBD2 scanner is what you’ll want to get the job done.
There’s more to these scan tools than reading and clearing trouble codes. Many can also perform repair functions like bleeding your brakes, while advanced models even allow you to diagnose other systems of the vehicle.
Choosing the right ABS/SRS reader comes down to finding a device that’s compatible with your vehicle and offers the functions you need. The good news is, it doesn’t need to cost a fortune and can save you money down the line by letting you make your own repairs at home.

Key Features
An ABS and airbag code reader is a piece of automotive diagnostic equipment that allows you to read data from the engine computer. Basic code readers are designed to work with the OBD2 (onboard diagnostic) system, which provides trouble codes and sensor readings from the engine but isn’t compatible with other vehicle systems. That’s where an ABS/SRS code reader comes in. These devices are designed to work with the anti-lock brake system (ABS) and airbag system (SRS) in the same way basic code readers communicate with the engine.
The most obvious advantage of this is the ability to turn off the associate warning lights for those systems without going to a garage. Most of these SRS and ABS scanners can do a lot more than that, though. Let’s take a look at the key features you can expect from these devices.
ABS and SRS scan tools’ functionality varies widely, from basic models that only read and clear trouble codes to professional SRS/ABS diagnostic tools with full programming and coding capabilities.
Generally speaking, beginning home mechanics and DIY-ers will only need a code reader that provides the basic features listed below. The Advanced Features will primarily be of use to professionals and experienced home mechanics.
Basic Key Features of ABS SRS code reader
Read and erase ABS/SRS trouble codes. Trouble codes are the warnings generated by these systems when something is amiss. Once triggered, they’ll activate the associated dash warning light to let you know there’s a problem. Reading the code enables you to identify the issue. You can then clear it once it’s fixed to turn off the light.
Read and erase engine DTCs. Most ABS/SRS scanners support at least some of the 10 OBD2 Modes. At the least, you can expect them to read and clear diagnostic trouble codes that trigger your check engine light.
Read live data. Live data reading enables you to see sensor readings, engine temperature, and other valuable information in real-time. Most SRS/ABS readers can show you information from the brakes, airbags, or engine, which can be a great help in identifying the cause of pesky trouble codes.
EVAP system tests. The main focus of the OBD2 system is vehicle emissions. Many of the modes are designed with this in mind, allowing you to test the oxygen (O2) sensors or other emission system areas. This lets you be prepared for the emission and smog checks that are often part of state vehicle inspections.
I/M readiness. This mode of OBD2 evaluates your system’s preparedness for emissions tests and is another helpful feature for preparing for smog and emission checks.
Read VIN data. Every car that’s made has a unique VIN code that gives you important information like the vehicle’s manufacturer and model, as well as where and in what year it was made. You can also retrieve information on the car’s features and specifications with this function, which can help replace parts or make other at-home repairs.

Advanced Features Of ABS Scan Tools
ABS Manual Control Tests. Also called active testing or bi-directional control, this feature enables you to activate mechanical and electronic components in your vehicle manually. Testing individual sensors, valves, and solenoids allows you to locate and repair malfunctions more quickly.
ABS Motor Test. The motor drives the pumping action that helps you stop without skidding in icy weather. An ABS motor test allows you to manually control the pump motor and ensure it’s working the way it should.
ABS Version Test. Similar to VIN data, this tells you useful information about the ABS, including the version number, software ID, and sequence value. You’ll need this information if you plan to repair or replace parts of the system.
Actuator Tests. A form of manual control, this lets you test the AYC valves, inlet valves, outlet valves, TRACS valves, and pump motors of the ABS.
ABS Bleeding. Air bubbles can get into the hydraulic brake lines during repairs or servicing, impeding their function. Bleeding the brakes removes this air to keep things running smoothly. ABS tools often include an automatic brake bleeding program that removes the air for you, saving you the hassle of bleeding out the air manually.
Advanced Features Of SRS Scan Tools
Check the airbag system. Diagnostic functions on SRS scanners go deeper than just reading trouble codes. You can check every aspect of your airbag system with these tools, identifying issues you’d otherwise need a mechanic to correct.
Reset SRS Control Module. The SRS system needs resetting after you install a replacement airbag. This function allows you to do so in your home garage.
Ensure the airbag system is functioning normally. Unlike other systems, you won’t always be able to tell if the airbags are working correctly during day-to-day driving. An SRS scan tool has systems that ensure all safety systems are functional when you need them.
Highly recommended: If you’re looking to buy an OBD2 scan tool with full SRS and ABS services and active tests, take Foxwell NT630 Plus.

How To bleed ABS brake with a scan tool
Some ABS systems can be bled manually, but this can be a tedious process and it won’t work for all vehicles. Scan tools allow you to activate the pumps and cycle the valves in the system, pushing air out.
As with the SRS reset above, you should check the tool manual to make sure of the exact steps before you start. Generally, though, it’s pretty straightforward:
- Locate the OBD2 port in your vehicle and plug in the ABS diagnostic tool.
- Turn the vehicle key on without starting the engine. The scan tool should turn on automatically when you do this.
- Locate the Automated bleed function on the scan tool. Some tools will automatically read your VIN data, while others will require you to enter the vehicle data manually.
- Verify the vehicle is in park, then start the process.
- The scan tool will instruct you to press down on the brake pedal. Follow the instructions on the screen until the process finishes. The whole process usually takes less than 5 minutes.
