Understanding OBD2 Scanners

OBD2, which stands for On-Board Diagnostics 2, is a standardized system implemented in vehicles manufactured since 1996. This system monitors various components and systems within your car, detecting malfunctions and storing relevant data in the onboard computer. An OBD2 scanner acts as the bridge between you and this treasure trove of information.

How Vehicle Code Readers Work

The process is relatively simple:

1. Locate the OBD2 port: Usually found under the dashboard on the driver’s side.
2. Connect the scanner: Plug the scanner into the OBD2 port.
3. Turn on the ignition: This powers up the scanner and allows it to communicate with the car’s computer.
4. Read the codes: Select the “Read Codes” function on the scanner. It will retrieve and display any stored DTCs.
5. Interpret the codes: Refer to the scanner’s manual or an online database to understand what each code signifies.
