Torque Pro is a popular OBD2 scan tool app, often used with Bluetooth adapters costing under $200. A common question is whether these tools can read Anti-lock Braking System (ABS) codes. The answer is: it depends.
OBD2 primarily covers emissions systems and related sensors. Traditionally, ABS was not included in the protocol. Each manufacturer used its own method for communicating with ABS modules. This means some older vehicles require proprietary software or tools to access ABS data.
However, newer vehicles often incorporate ABS information into the OBD2 standard. In these cases, Torque Pro, along with a compatible adapter, can successfully read ABS Diagnostic Trouble Codes (DTCs). Specifically, Torque can read P, U, B, and C trouble codes, provided the manufacturer fully adheres to the OBD2 standard for retrieving DTCs. Modern vehicles are increasingly compliant, while older models often lack this capability.
It’s important to understand that the Bluetooth adapter itself does not determine ABS code readability. All adapters essentially perform the same function – transmitting and receiving data. The vehicle’s OBD2 implementation and the software’s ability to interpret that data are the deciding factors.
For older vehicles with proprietary ABS systems, reading codes might require specialized plugins within the Torque app. The app does offer an Application Programming Interface (AIDL) that allows developers to create such plugins. Additionally, Torque can sometimes access specific ABS data, like Ford ABS wheel speeds, through predefined Parameter IDs (PIDs) found in the app settings.
In conclusion, while not all OBD2 scan tools under $200 can read ABS codes on every vehicle, many can, particularly on newer models. The key is compatibility between the vehicle’s OBD2 system, the scan tool software (like Torque Pro), and potentially the use of specialized plugins for older vehicles. When choosing a scan tool, research its capabilities and compatibility with your specific vehicle’s make and model year.
