What is a Computer Scan Tool?
A computer scan tool, also known as an OBD2 scanner, is an electronic device that connects to your car’s onboard computer system through the OBD-II port. This port, usually located under the dashboard on the driver’s side, acts as a communication gateway allowing the scan tool to access data from various sensors and modules within the vehicle.
How Does a Computer Scan Tool Work?
Imagine your car’s computer system as a network of sensors constantly monitoring various functions like engine performance, emissions, transmission, and more. When an issue arises, the corresponding sensor sends a signal to the car’s computer, often triggering a warning light on your dashboard. A computer scan tool acts as a decoder, translating these signals into understandable diagnostic trouble codes (DTCs). These codes, along with live data streams from the sensors, provide valuable insights into the nature and severity of the problem.
