What Is an Automotive Code Reader?

An automotive code reader is a diagnostic tool that connects to your car’s onboard computer system to retrieve error codes. These error codes correspond to specific issues, such as engine misfires, transmission glitches, or sensor failures.

How Does It Work?

  • Read Diagnostic Trouble Codes (DTCs): The reader retrieves codes stored in the vehicle’s system.
  • Interpret the Codes: With a quick Google search or the reader’s app, you can decode what the problem is.

Fun Fact: OBD stands for On-Board Diagnostics, a standard for vehicles manufactured since 1996.
