From there, the OBD2 standard was rolled out step-by-step:

● 1996: OBD2 was made mandatory across USA for cars and light trucks
● 2001: Required in EU for gasoline cars
● 2003: Required in EU also for diesel cars (EOBD)
● 2005: OBD2 was required in US for medium duty vehicles
● 2008: US cars were required to use ISO 15765-4 (a variant of CAN) as basis for OBD2
● 2010: Finally, OBD2 was required in US heavy duty vehicles

Today, the OBD2 standard is vital in facilitating easy error resolution.
