A Scan Tool or Diagnostic Tool is used to connect to the vehicle's data link connector, obtaining Diagnostic Trouble Codes and other sensor data to diagnose and troubleshoot vehicle issues.

A Scan Tool or a Diagnostic Tool is what connects to the vehicle's data link connector (DLC) to obtain Diagnostic Trouble Codes (DTCs) and other engine sensor data. These tools are used by repair technicians to diagnose and fix problems that emerge with modern vehicles. These tools provide precise readings which indicate where the problem lies within the vehicle's intricate components.

For example, if a check engine light comes on in a vehicle, a scan tool can be plugged into the DLC. The tool will generate corresponding codes which will indicate the source of the problem. It could be an emissions control problem, an engine management issue or even a transmission problem. These codes are then used to perform specific repairs or component replacements.
