Frequently Asked Questions About OBD2 Scanners
What is an OBD-II Scanner?
An OBD-II (On-Board Diagnostics II) scanner is a device that connects to your car’s onboard computer system, typically through the OBD-II port. It reads diagnostic trouble codes (DTCs) and other data related to your vehicle’s engine, emissions, and other systems, helping you understand and diagnose potential problems.
What is the OBD-II Port?
The OBD-II port is a standardized connector found in most cars manufactured after 1996. It’s usually located under the dashboard on the driver’s side. This port allows communication between diagnostic tools like OBD-II scanners and the car’s computer.
What is a DTC?
DTC stands for Diagnostic Trouble Code. These are codes generated by your car’s onboard computer when it detects a problem.
