In their evaluation level, the BMW cars were and also now exceed possibilities, intended by OBD-II. Why one more, independent system would be necessary? ItвЂ™s clear, why OBD-II system should be available вЂ“ itвЂ™s required by the standard. Second system: EDIABAS (Electronic Diagnosis and Information protocol) вЂ“ unique, developed and intended only for BMW vehicles: diagnostics, test and information system.First system: вЂњsubsistence minimumвЂќ, defined in OBD-II standard.The special part is following: while conceding with requirements of OBD-II requirements, BMW continued and continues to maintain TWO INDEPENDENT error and diagnostics systems in parallel! Note: I deliberately will not a mean many standards, which define plugs, data exchange and other technical things вЂ“ I will pay my attention to a thing by nature. So far everything sounds logical вЂ“ BMW, tried several types of their own diagnostic plugs, conceded with OBD-II standard requirements. With the introduction of this plug, BMW obeyed requirements of OBD-II standard, which was supposed to be used by all car manufacturers. I believe, almost all of you have seen large, round 20 pin diagnostic connectors of BMW, which were used in BMW E38, E39, and other cars.Д«efore this connector, also connector with 15 pins was in use вЂ“ it was with a smaller diameter, used in E30 generation cars вЂ“ I believe, not many of you have seen that and still remember.ДЄround the Year 2000 (with E39 LCI generation) BMW switched to 16 pin connector, mentioned in OBD-standard: Including standard, how does the connection to carвЂ™s diagnostic looks alike, and how the data exchange between car and diagnostics tool is organized.

Initially, the process was chaotic вЂ“ each car manufacturer introduced his own, completely different standard. It was a logical process вЂ“ equipment can get damaged, they have to be repaired. One of the things, regarding which I was very surprised вЂ“ most BMW users are reading the error messagesвЂ¦ Completely incorrect! How so?ДЄ long time ago, as soon as electronic devices appeared in cars, manufacturers started to introduce self-diagnostics and diagnostics possibilities. So IвЂ™m very surprised when it turns out вЂ“ not everything is as I have imagined. IвЂ™m interested in BMW cars for already 25 years, and quite many things are self-evident for me.
