Introduction to OBD Scanners

Modern vehicles are equipped with sophisticated onboard computer systems that monitor various components and systems to ensure optimal performance. An On-Board Diagnostics (OBD) system is a standardized computer system that helps detect and report any malfunctions or issues in a vehicle. OBD scanners are diagnostic tools used to interface with the OBD system and retrieve valuable diagnostic information.

Understanding On-Board Diagnostics (OBD)

The OBD system in your car continuously monitors various parameters such as engine performance, fuel efficiency, emission levels, and other vital components. It generates fault codes, also known as Diagnostic Trouble Codes (DTCs), whenever it detects a problem. These fault codes provide valuable information about the specific issue affecting your vehicle.
