1.1. History and Evolution of OBD2

How did OBD2 evolve to its current form? The evolution of On-Board Diagnostics (OBD) began in the late 1960s in California, driven by stricter emissions regulations. According to the California Air Resources Board (CARB), the initial OBD systems were rudimentary, offering limited diagnostic capabilities.

The Timeline of OBD Evolution:

• OBD-I (1980s): Early systems, manufacturer-specific, limited diagnostic capabilities.
• OBD-1.5 (Early 1990s): Transitional phase with some standardization, but still manufacturer-dependent.
• OBD-II (1996): Standardized system mandated in the US, enhanced diagnostic capabilities, universal diagnostic connector.
• EOBD (European OBD): Introduced in the early 2000s, aligned with OBD-II standards.
• JOBD (Japanese OBD): Introduced in the early 2000s, similar to OBD-II.

The shift to OBD-II in 1996 marked a significant turning point. According to the Society of Automotive Engineers (SAE), OBD-II standardized the diagnostic connector, fault codes, and communication protocols, making it easier for technicians to diagnose and repair vehicles, and is still used today.

1.2. Key Components of the OBD2 System in a Jeep Wrangler

What are the essential components that make up the OBD2 system in a Jeep Wrangler? The OBD2 system in a Jeep Wrangler comprises several key components working together to monitor and report on the vehicle’s performance.
