What’s a bidirectional scanner?

Known as Coding Scanner, a Bidirectional scanner is an electronic tool used to connect with, diagnose & sometimes reprogram vehicle control modules.
Modern cars come with an onboard diagnostics chip (at least a basic model). Connecting the Bidirectional scanner with the onboard chip using the vehicle’s data link connector (DLC) will let you see its diagnostic information.
It will also tell what is & what isn’t functioning precisely & you can send commands to test various modules in your car’s ODC.
As a Bidirectional scanner’s primary purpose is to handle a vast array of problems that cars might have, it will give an additional way to find out & fix problems.

What does a bidirectional scan tool do?

A traditional tool can perform system tests only. In comparison, a Bidirectional scan tool can read the OBD’s input & diagnostic information more. Not only that, it can send outputs to test other modules of your car, including –

  • Anti-lock Braking System (ABS).
  • Temperature sensor.
  • Transmission function.
  • Engine function.
  • Battery health.
  • Door lock system.
  • Oxygen & Air pressure.

After testing all those modules, the scanner will indicate that no problems were found or presented with an error code. More recent scanners’ models might notify you in advance when a car’s module might fail in the future, giving you the option for taking precautions.

*Note – Bidirectional Scan tools can only identify any problems you face with your car right now or will be in the future. Those scan tools can’t fix any of those problems, only identification.

If you are interested in diagnosing your car at home rather than taking it to a service center, you should get an affordable bidirectional scanner. These tools tend to run around $600. But, before purchasing a Bidirectional scan tool, there are some factors you need to consider first.
