Cen Tech OBD2 Scanner Features
What is a Cen Tech OBD2 & CAN Scan Tool?
A Cen Tech OBD2 & CAN scan tool is a handheld device that plugs into your car’s OBD2 port, typically located under the driver’s side dashboard. This port, mandatory on all cars manufactured after 1996, acts as a gateway to your car’s computer system. The scan tool communicates with this system, reads diagnostic trouble codes (DTCs), and displays them on its screen.
But it’s not just about reading codes. A good OBD2 scanner, like the Cen Tech model, can:
- Display live sensor data: See real-time information from your car’s sensors, such as engine RPM, coolant temperature, oxygen sensor readings, and more.
- Clear DTCs: After addressing a problem, you can use the scan tool to erase the error codes and turn off the check engine light.
- Perform special tests: Depending on the model and your car’s make and model, a Cen Tech scan tool might be able to perform component tests or initiate specific system functions.
