This interface was made in different varieties and changed with power train control modules (aka PCM, ECM, ECU).

GM's ALDL (Assembly Line Diagnostic Link) is sometimes referred as a predecessor to, or a manufacturer's proprietary version of, an OBD-I diagnostic.

2010: HDOBD (heavy duty) specification is made mandatory for selected commercial (non-passenger car) engines sold in the United States.

2008: Certain light vehicles in China are required by the Environmental Protection Administration Office to implement OBD (standard GB18352 ) by July 1, 2008.

2008: All cars sold in the United States are required to use the ISO 15765-4 signaling standard (a variant of the Controller Area Network (CAN) bus).2006: All vehicles manufactured in Australia and New Zealand are required to be OBD-II compliant after January 1, 2006.2004: The European Union makes EOBD mandatory for all diesel vehicles sold in the European Union.2001: The European Union makes EOBD mandatory for all gasoline (petrol) vehicles sold in the European Union, starting in MY2001 (see European emission standards Directive 98/69/EC ).1996: The OBD-II specification is made mandatory for all cars sold in the United States.The DTCs and connector suggested by the SAE are incorporated into this specification. ~1994: Motivated by a desire for a state-wide emissions testing program, the CARB issues the OBD-II specification and mandates that it be adopted for all cars sold in California starting in model year 1996 (see CCR Title 13 Section 1968.1 and 40 CFR Part 86 Section 86.094).The Society of Automotive Engineers (SAE) recommends a standardized diagnostic connector and set of diagnostic test signals. The data link connector and its position are not standardized, nor is the data protocol. These requirements are generally referred to as 'OBD-I', though this name is not applied until the introduction of OBD-II. 1988: The California Air Resources Board (CARB) requires that all new vehicles sold in California in 1988 and newer vehicles have some basic OBD capability.This protocol is defined in GM XDE-5024B. 1986: An upgraded version of the ALDL protocol appears which communicates at 8192 baud with half-duplex UART signaling.1982: RCA defines an analog STE/ICE vehicle diagnostic standard used in the CUCV, M60 tank and other military vehicles of the era for the US Army.Real-time sensor data, component overrides, and Diagnostic Trouble Codes (DTC's) are also displayed through the electronic climate control system's digital readout when in diagnostic mode. The protocol communicates at 160 baud with Pulse-width modulation (PWM) signaling and monitors all engine management functions.

A proprietary 5-pin ALDL interfaces with the Engine Control Module (ECM) to initiate a diagnostic request and provide a serial data stream. 1980: General Motors introduces the first digital OBD system on their 1980 Eldorado and Seville models.These systems are also analog in nature, though some provide rudimentary diagnostic capability through factory tools, such as the Kent Moore J-25400, compatible with the Datsun 280Z, and the Cadillac Seville. 1975: Bosch and Bendix EFI systems are adopted by major automotive manufacturers in an effort to improve tail pipe emissions.This system is entirely analog with no diagnostic capabilities. 1968: Volkswagen introduces the first on-board computer system, in their fuel-injected Type 3 models.You can help by converting this section, if appropriate.

Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow a person to rapidly identify and remedy malfunctions within the vehicle. Early versions of OBD would simply illuminate a malfunction indicator light or ' idiot light' if a problem was detected but would not provide any information as to the nature of the problem. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. On-board diagnostics ( OBD) is an term referring to a vehicle's self-diagnostic and reporting capability. Used to connect to the SAE J1962 Data Link Connector (DLC) found in many cars of the era. Various angles and details of a 'MaxScan OE509' - a fairly typical onboard diagnostics (OBD) handheld scanner from the first decade of the 21st century.
