The ABS (Anti-lock Braking System) light illuminating on your dashboard can be concerning. It signals a potential issue within your vehicle’s braking system, a critical safety component. If you’re seeing this warning light and wondering how to diagnose the problem without immediately heading to a mechanic, you might be asking: Do Obd2 Scan Tools Read Abs Lights? The answer is yes, many modern OBD2 scan tools are capable of reading and diagnosing ABS light issues, offering a convenient way to understand what might be wrong.
This guide will explore how OBD2 scan tools can help you decipher the mystery behind your ABS light, providing insights into the diagnostic process and empowering you with the knowledge to take informed action.
Understanding Your ABS Light and the Need for Diagnosis
The Anti-lock Braking System is designed to prevent wheel lock-up during hard braking, allowing you to maintain steering control in emergency situations. When the ABS light comes on, it indicates that the system has detected a malfunction. This could range from a sensor issue to problems with the ABS module itself. Ignoring the ABS light is not recommended as it could compromise your vehicle’s safety.
Traditionally, diagnosing ABS issues required specialized equipment at a mechanic’s shop. However, with the advent of affordable and user-friendly OBD2 scan tools, preliminary diagnosis is now within reach for car owners and DIY enthusiasts.
Can OBD2 Scanners Really Read ABS Codes?
Yes, many OBD2 scan tools available on the market today are equipped to read ABS (Anti-lock Braking System) codes, in addition to the standard engine and emissions-related codes. While basic OBD2 scanners might only cover engine codes, more advanced or specialized tools often include ABS and other system diagnostics.
To confirm if an OBD2 scanner reads ABS codes, check the product specifications or description. Look for features like “ABS diagnostics,” “ABS code reader,” or “System Scan” which usually indicates enhanced diagnostic capabilities beyond just the engine control unit (ECU). Tools like the Innova 5210 and higher models are specifically designed to access ABS and SRS (Supplemental Restraint System) data, making them excellent choices for diagnosing brake system issues.
Benefits of Using an OBD2 Scanner for ABS Light Diagnosis
Using an OBD2 scanner to investigate your ABS light offers several advantages:
- Convenience: Diagnose your vehicle’s ABS system from the comfort of your garage or driveway. No need to immediately schedule a mechanic appointment for a preliminary check.
- Cost-Effective Initial Diagnosis: Save on initial diagnostic fees at a repair shop. An OBD2 scanner allows you to get a trouble code and understand the potential issue before seeking professional help.
- Faster Problem Identification: Quickly pinpoint the potential area of the problem. OBD2 scanners provide specific trouble codes that narrow down the source of the ABS light.
- Empowerment and Informed Decisions: Understanding the ABS code empowers you to have a more informed conversation with your mechanic, potentially saving time and money on unnecessary repairs.
- DIY Repair Potential: For some simpler ABS issues, knowing the code might enable you to perform the repair yourself, especially if it’s a sensor-related problem.
Step-by-Step Guide: Using an OBD2 Scanner to Check Your ABS Light
Here’s how to use an OBD2 scan tool to check your ABS light:
-
Purchase a Compatible OBD2 Scanner: Select an OBD2 scanner that explicitly states it reads ABS codes. Tools like the Innova 5210 are excellent entry-level options that support ABS diagnostics. For more advanced features, consider higher-end models like the Innova 5410.

Connect the Scanner: Plug the OBD2 scanner into the port securely.
-
Turn Ignition to “ON” Position: Turn your vehicle’s ignition to the “ON” position without starting the engine. This powers up the car’s electronics and allows the scanner to communicate with the vehicle’s computer.
-
Navigate to the ABS Section: Power on your OBD2 scanner and navigate to the “ABS” or “Anti-lock Brake System” section in the tool’s menu. The exact menu names may vary slightly depending on the scanner model.

Interpreting ABS Codes and Deciding Your Next Steps
Once you have the ABS trouble codes, you can research their meaning online or within the RepairSolutions2 app. These codes provide clues to the potential problem areas, such as wheel speed sensors, ABS pump motor, or hydraulic control unit issues.
Based on the code and your comfort level, you have options:
- DIY Repair: For simpler issues like a faulty wheel speed sensor, you might be able to perform the repair yourself after researching the code and repair procedures.
- Professional Mechanic: For more complex issues or if you are not comfortable with DIY car repairs, take your vehicle to a trusted mechanic. Having the ABS codes will help them diagnose the problem more efficiently.
Important Note: Never ignore an ABS light. Even if your brakes seem to be functioning normally, a problem within the ABS system can compromise your vehicle’s safety in emergency braking situations.
Choosing the Right OBD2 Scanner for ABS Diagnostics
When selecting an OBD2 scanner for ABS light diagnosis, consider these factors:
- ABS Diagnostic Capability: Ensure the scanner specifically lists ABS diagnostics as a feature.
- Ease of Use: Look for a scanner with an intuitive interface and clear instructions.
- Compatibility: Verify the scanner is compatible with your vehicle’s make and model.
- Companion App Support: Scanners that work with mobile apps like RepairSolutions2 offer significant added value in terms of code explanations, repair guidance, and cost estimations.
- Budget: OBD2 scanners range in price. Determine your needs and budget accordingly. Entry-level tools like Innova 5210 are a great starting point, while more advanced tools offer broader capabilities for professional use or serious DIYers.
