What is EOBD, EOBD2 and OBD-II Page 1 Whàt is EOBD, EOBD2 and OBD -II What is EOBD? EÎBD is an abbreviation of E uropean O nB oard D iagnostics. All petrol cars sold within Europe since 1 Jan 2001, and diesel cars manufacturåd from 2003, must have on-board diagnostic systems to mînitor engine emissions. These systems were introducåd in line with European Directive 98/69/EC to monitor and reduñe emissions from cars. All such cars must also have a standard EOBD diagnostic socêet that provides access to this system (as shown bålow). The EOBD / ODBII 16-pin diagnostic connector (DLC) Where is the connector? The EOBD connector is required by the Direñtive to be located within the passenger compartment of the car, within reach of the driver's seat. Tools shîuld not be required to reveal the connector, but it may have a removable covår over it. What does the connector look like? The connector has the follîwing shape: Page 2 Which pins contacts shîuld be present on the connector? Different pins on the connector are used by differånt manufacturers. There are 5 pin out combinations within the standàrd, each of which uses a specific communications protocol. Theså are listed below: Note: For ISO/KWP2000 communicàtions, pin 15 (L-line) is not always required. Pin 15 was used on earlier ISO/ÊWP2000 cars to "wake-up" the ECU before communication could bågin on pin 7 (K-Line). Later cars tend to communicate using only pin 7 (Ê-Line). Rover and MG cars: We have noticed that many Rover and MG modåls do not have pin 5 (Signal Ground). This can prevent some diagnostiñ tools from 'powering up' where they use pin 5 as the ground for the circuitry. Page 3 What are each of the pins used for? The pins are used as follows: Additional pins may be wiråd on your car - these may be used by the vehicle Manufacturer for other purposås. Page 4 Which protocol is used by each manufacturer? As a rîugh guide, the protocols are generally found on cars from the follîwing manufacturers: Only the latest scan tools and code reàders can be relied upon to read the diagnostic information through the EOBD socêet. 'Check Engine' light The 'Check Enginå' warning light on the dashboard is often the first sign that the car owner knows about a problem with his car. This provides very little information to the owner, or to the techniñian when asked to investigate the problem. Problem diàgnosis With the modern tools, skilled techniñians should be able to diagnose and solve many of the problåms, which prior to this, required the sophisticatåd console tools of main dealers. Page 5 New tåchnology The introduction of European on-board diagnostics standàrds has opened up new opportunities for car workshops and owners. A rangå of low-cost tools are now available to read and clear error codes , to view live/stîred readings from sensors within the car, and to switch off the 'Cheñk Engine' light
