About OBD II

OBD II stands for On-Board Diagnostics version II. OBD II is a system that the Society of Automotive Engineers (SAE) developed to standardize automotive electronic diagnosis to minimize vehicle pollution and to allow you to use the same tool to test any make and model without special adapters. The SAE established guidelines that provide:

a universal diagnostic test connector, called the data link connector (DLC), with dedicated pin assignments.

a standardized location for the DLC, visible under the dash on the driver’s side.

a standardized list of Generic diagnostic trouble codes (DTCs) used by all manufacturers. Certain DTCs are reserved for the manufacturer.

SAE publishes recommendations, not laws, but the Environmental Protection Agency (EPA) and California Air Resources Board (CARB) made many of SAE’s recommendations legal requirements that car makers were required to phase in over a three-year period. Beginning in 1994, vehicles with a new engine management computer

about 10% of each manufacturers fleet – were supposed to comply with OBD II standards. For 1995, OBD II systems were to appear on about 40% of the new vehicles sold in the USA. Some of the 1994-1995 OBD II systems were not fully compliant, so the Government granted waivers to give manufacturers time to fine-tune their systems. Beginning in 1996, most of the new vehicles sold in the USA were fully OBD II compliant.
