Global OBD Vehicle Communication Software Manual | Global OBD and What it Means As a result of increasing emission levels around the world, many countries have enacted strict emission related regulations that will drive increased technology into the modern automobile in order to reduce the exhaust emissions. European and North American countries lead the way by adopting technology that will standardize the way these vehicles can be checked for compliance. The OBD-I (On-Board Diagnostics I) system was introduced in the early 1980’s and by 1988 all new cars and light trucks sold in California had to have OBD-I. The fundamental elements of the OBD-I are the electrical components (which influence exhaust emissions) that are monitored by the engine management system. An optical warning signal is given in the event of an OBD-I relevant failure. This fault can be read out by way of a flashing code.

(European On-Board Diagnostics) is Europe’s equivalent to OBD-II. It was introduced in 2000 and became effective in January 2001. There are a few differences between EOBD and OBDII but none that will affect the generic scan tool operation. All the communication protocols for both programs are identical. Vehicle emission strategies and certification procedures vary between countries, states and regions. Always use the vehicle factory service information specific to the country and emission certification. EURO-3 is a continuation of the emission regulations known as EURO-1 and EURO-2. In addition to introducing stricter emission limits, the directive now also covers the monitoring of emission related components and functions during operation, i.e. EOBD. The OBD-II and EOBD system must show the failure of an emission related component or system to the driver using a MIL (Malfunction Indicator).
