1. Understanding OBD1 and OBD2 Systems

The transition from OBD1 to OBD2 was a significant leap in automotive diagnostics. OBD1, or On-Board Diagnostics 1, was the early generation of vehicle diagnostic systems. OBD2, or On-Board Diagnostics 2, is a standardized system introduced in the mid-1990s, offering enhanced diagnostic capabilities.

1.1 Key Differences Between OBD1 and OBD2

OBD1 systems, prevalent in vehicles manufactured before 1996, lack the standardization of OBD2, creating challenges for mechanics and car owners. Conversely, OBD2 offers standardized diagnostic trouble codes (DTCs) and a universal connector.

Feature	OBD1	OBD2
Standardization	Non-standardized	Standardized
Connector	Multiple types	Standard 16-pin connector
Diagnostic Codes	Manufacturer-specific	Standardized DTCs
Data Access	Limited and manufacturer-dependent	Enhanced, with a wide range of parameters
