What is a Bi-Directional scan tool?

A Bi-Directional scan tool allows you to send and receive information to and from a car’s onboard database. This scan tool usually has more advanced features than an ordinary scan tool. With a Bi-Directional scan tool, you can conduct tests and solve problems within your car’s diagnosis system.

How does a Bi-Directional control work?

The Bi-Directional control works by allowing the mechanic to use the tool to send and receive data from a car. For instance, instead of reading a DTC error code, the device allows you to test different systems or open and close valves within the car to tackle the problem.

What is the difference between a Bi-Directional scan tool and a regular scanner?

A Bi-Directional scan tool is more advanced than typical scan tools. A regular scanner reads and clears codes on your car. That’s the reason you see data parameters when you connect the OBD to its port below the dashboard(underneath the steering wheel). A Bi-Directional scan tool, it has a bi-directional control that commands specific operations in the car.

What is the main use of a Bi-Directional scanner?

The main use of a bidirectional scanner is to request the control module to conduct particular functions. Some of the functions include actuator tests, inspection tests, system tests, functional tests, re-initialization, and reprogramming. Unlike usual scan tools, bi-directional scanners reduce your diagnostic time.

Who is best suited for a Bi-Directional scan tool?

Bi-Directional scanners are best suited for professional technicians and mechanics who have a lot to diagnose and know about different vehicles. Bi-Directional scanners not only perform advanced functions but can be utilized to perform specific functions.
