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

ABS/SRS code readers basic key features
Six basic key features of ABS/SRS code readers.

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.

If you’re looking to buy an OBD2 scan tool with full ABS services and active tests, take Foxwell NT630 Plus.

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.

Other Considerations

Software Updates

Updates don’t just improve the software’s performance, they’re also necessary to get the most up to date repair information. Some tools offer free updates for life, while others will require a paid subscription.

If the ABS or airbag scanner has Wi-Fi or Bluetooth you can update it straight through the device. Otherwise, you’ll need to connect it to a computer first. Many tools are only compatible with PCs for updates, so keep that in mind if you’re a Mac user.


The more advanced the processor in the scan tool, the faster it can deliver results. This doesn’t just save time, either. Scan tools that can read information more quickly are able to give more accurate real-time sensor data without lags or gaps.

Along with the processing speed, consider the speed of navigating the tool. Functions like health reports and one-touch diagnostic checks can take a lot of the tedious work out of diagnostics.

Customer Support

A strong support system is especially necessary when something goes wrong with your tool. Many scan tool companies also have active online communities or networks of certified mechanics who can provide a more advanced form of support, giving you experienced-backed repair suggestions you can’t get from any tool.

Final Thoughts

Choosing the right ABS SRS code reader starts by deciding which features and functions you need. As an everyday driver, basic code reading and PID data reading, like you’ll get with models such as BlueDriver or the Launch CRP123X, should be plenty.

On the other hand, professional mechanics will want a model that’s capable of more in-depth diagnostic and repair functions. Bi-directional testing is another helpful feature for professionals, allowing you to identify malfunctioning sensors, valves, and other components.

Whichever way you go, one of the scanners above should fit your needs! We hope this review has helped you figure out the right SRS/ABS code reader for you.

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:

  1. Locate the OBD2 port in your vehicle and plug in the ABS diagnostic tool.
  2. Turn the vehicle key on without starting the engine. The scan tool should turn on automatically when you do this.
  3. 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.
  4. Verify the vehicle is in park, then start the process.
  5. 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.

11. Does the Innova 3100J read all SRS and ABS codes?

This tool can read all trouble codes put out by the SRS, ABS, and engine systems. However, it cannot clear permanent codes, which are activated when there is an immediate safety issue with the system. For those, you’ll need to go to a mechanic or get a professional scan tool. 

12. Does the Innova 3100J work right out of the box?

Yes, it arrives ready to go without needing initial updating or set-up. You can also use the tool without registering it, though you’ll need to do so when it’s time to update or request service. 

13. What is the difference between the Launch CRP123 and the Launch CRP123X?

The CRP123X is the upgraded version of the Launch CRP123. It has expanded vehicle coverage, more language options, and extra functions like auto VIN and a one-click update through Wi-Fi. Between the two, the Launch CRP123X is the better option for most users. 

14. Does the Launch CRP123X read real-time transmission data?

Yes, you can read several parameters from the transmission in real-time, including temperature and other performance data. 

15. Can you bleed ABS using the Launch CRP123i?

The Launch CRP123i has a broad compatibility, with coverage for more than 10,0000 cars, trucks, and SUVs. It will read transmission codes for the majority of vehicles on the road today, but having said that, no scan tool is 100% comprehensive. If you want to verify that it will read transmission codes for your vehicle, your best bet is to contact Launch customer support before you buy it.

17. What makes the Launch 129i different from the Launch CRP123 line?

The main difference is the inclusion of service functions like oil reset and SAS calibration. The Launch CRP123 line of scan tools can perform 4-system diagnosis and battery monitoring similar to what the Launch 129i offers, but lack the 5 reset functions it includes.

18. Will the Launch 129i work on diesel trucks?

Yes, as long as they’re from one of the 57+ manufacturers included in its compatibility. This includes larger trucks like the Ford F250 Super Duty.

19. How do you add additional vehicles to the Autel Diaglink?

For each make and model of vehicle you want to diagnose with the Autel Diaglink, you’ll need to download the corresponding software. Start by purchasing the software from their website then log in to the PC suite for the scan tool. Once you do this, your download list should sync with the Autel database and you’ll be able to install the software on your device.

20. Does the Autel Diaglink work with Japanese vehicles?

If the vehicle uses the OBD2 diagnostic system, the Autel Diaglink will work with it. However, the Diaglink is not compatible with JOBD protocols. Check your user manual if you’re not sure which your vehicle uses.
