There’s no escape from electronic body computers in contemporary vehicles. The majority of repairs require diagnosis of the electronic computer units regardless the source of the problem. OBD socket started the standardization. In the 90s when OBD sockets appeared in vehicles there was a breakthrough in the field of diagnostic equipment. OBD System (On Board Diagnostic System) is an electronic system that helps provide specific data related to which system or component failed (and can have influence on higher emission of harmful substances) and help perform repairs. OBD systems were implemented in vehicles in the 70s, however, it was later (in the US in 1996 and in Europe in 1998-2000) that critical regulations were established which stated that OBD system must inform the driver about problems inside a vehicle. Moreover, before the regulations car manufacturers had their own trouble codes which could only be read by means of sophisticated equipment available in authorized car workshops. The new law stated that every single vehicle has to be equipped with a standard 16-pin socket connector allowing for reading fault codes. Unfortunately it doesn’t work with trucks because in trucks OBD II connector is not required. If it happens that there is an OBD II connector in a truck, only power pins are compatible. (Scania, for instance, has CAN communication line on pins 6,14 and Renault on pins 2,13). That’s why knowledge and professional equipment are required.
