Let’s dive in!

Receiving information between one device and another is usually called a bidirectional control and it is a widely used generic term.

What is a Bidirectional Scan Tool?

Unlike the generic code readers which are specifically designed to only read and delete error codes, the bidirectional scan tools can access different modules and give commands to perform a specific function. These functions may vary depending on what you need to achieve but they are often referred to as test functions.

Benefits of Using a Bidirectional Scan Tool

Using a bidirectional scan tool offers a lot of advantages over traditional OBD-II scanners. They give you access to a lot of vehicle systems, like the engine, transmission, ABS, and airbag modules.

This on the other hand helps you to make more precise diagnostics of the vehicle and dive deeper into the problem. With bidirectional tools, you can also reset service lights and do other maintenance tasks which make them essential tools, especially in the digital world we live in today.
