A bidirectional scan tool, also known as a bidirectional scanner, is a device that may be plugged into a vehicle’s diagnostic port and used to both read and write information to the vehicle’s electronic control units (ECUs) and other modules.
The many modules in today’s automobiles work together to form a seamless whole. However, whether or not a module and the range of options available for interacting with it relies on the quality of the scan tool used.
The ability to test actuators and conduct output tests to activate and deactivate the systems of the cars to test and evaluate their functionality is another exciting aspect of bidirectional scan tools.
The newer generation of OBD2 scanners is affordable and versatile, eliminating the need to take your car to the parts store.
