Understanding OBD2 Scanners: FAQs
What is an OBD2 scanner? An OBD2 (On-Board Diagnostics) scanner is a device that connects to your car’s OBD2 port, allowing you to access data from the onboard computer. This data includes diagnostic trouble codes (DTCs), which indicate specific problems, as well as live data streams that show real-time engine performance.
What is the OBD2 port? The OBD2 port is a standardized 16-pin connector located inside your car, typically under the dashboard on the driver’s side. Almost all cars manufactured after 1996 have an OBD2 port.
What is a DTC? A DTC is a code that represents a specific problem detected by your car’s computer. OBD2 scanners can read these codes and provide descriptions of the corresponding issues.
What do DTCs mean? DTCs are alphanumeric codes with a specific structure. The first letter indicates the system affected (P for powertrain, B for body, C for chassis, U for network). The following characters provide more specific information about the problem. Most OBD2 scanners will decode these for you.
