The Diagnostic Trouble Codes (DTC's) can be interpreted through the blinking pattern of the "Check Engine" (MIL) light. The only available function for the owner is "Blinky Codes". Implemented on California vehicles for the 1980 model year, and the rest of the United States in 1981, the ALDL was not intended for use outside the factory. The 'assembly line diagnostic link' ( ALDL) protocol communicates at 160 baud with Pulse-width modulation (PWM) signaling and monitors very few vehicle systems.

Simple OBD implementations appear, though there is no standardization in what is monitored or how it is reported.

1975: Datsun 280Z On-board computers begin appearing on consumer vehicles, largely motivated by their need for real-time tuning of fuel injection systems.

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 automotive 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.
