1. What Is an OBD2 Scanner?

An OBD2 (On-Board Diagnostics II) scanner is a device used to access and interpret data from a vehicle’s computer system. According to a 2023 report by IBISWorld, the automotive repair and maintenance industry in the US is worth $134 billion, highlighting the importance of efficient diagnostic tools. These scanners help diagnose issues by reading diagnostic trouble codes (DTCs) that the vehicle’s computer stores when it detects a problem. The OBD2 system, standardized in 1996, monitors various aspects of a vehicle’s performance, including emissions, engine, transmission, and more, as noted by the EPA (Environmental Protection Agency). Kragen, a well-known auto parts retailer (now part of O’Reilly Auto Parts), sold OBD2 scanners to both professional mechanics and DIY enthusiasts.

1.1 Understanding the OBD2 System

The OBD2 system is crucial for modern vehicle maintenance. As explained by the Society of Automotive Engineers (SAE), it standardizes diagnostic procedures across all vehicles manufactured for the US market since 1996. This system monitors nearly every part of the engine and emissions system, ensuring vehicles meet environmental standards.

1.2 What Does an OBD2 Scanner Do?

An OBD2 scanner performs several key functions:

• Reading Diagnostic Trouble Codes (DTCs): These codes indicate specific problems the vehicle has detected.
• Clearing Codes: After a repair, the scanner can reset the “Check Engine” light.
• Live Data Streaming: Displays real-time data from sensors, such as engine temperature, RPM, and O2 sensor readings.
• Vehicle Information: Retrieves the Vehicle Identification Number (VIN) and other identification data.
