Wandering off-topic but to add clarification:
EOBD is to all intents and purposes OBD2. EOBD refers to compliancy with EU directive 98/69/EC. This directive states which functions must be tested and the thresholds at which faults must be flagged. These limits are tighter than those specified by OBD2, however 98/69/EC mandates that the protocols that can be used are those that are also used by OBD2.

6.5.3. The emission control diagnostic system must provide for standardised and unrestricted access and conform with the following ISO and/or SAE standards. Some of the ISO standards have been derived from Society of Automotive Engineers Standards and Recommended Practices. Where this is the case, the appropriate SAE reference appears in parentheses.
6.5.3.1. One of the following standards with the restrictions as described must be used as the on-board to off-board communications link:
ISO 9141-2 'Road Vehicles - Diagnostic Systems - CARB Requirements for the Interchange of Digital Information`;
ISO 11519-4 'Road Vehicles - Low Speed Serial Data Communication - Part 4: Class B Data Communication Interface (SAE J1850)`. Emission-related messages must use the cyclic redundancy check and the three-byte header and not use inter-byte separation or checksums.
ISO DIS 14230 - Part 4 'Road Vehicles - Diagnostic Systems - Keyword Protocol 2000`.
6.5.3.2. Test equipment and diagnostic tools needed to communicate with OBD systems must meet or exceed the functional specification given in ISO DIS 15031-4.
6.5.3.3. Basic diagnostic data, (as specified in 6.5.1) and bi-directional control information must be provided using the format and units described in ISO DIS 15031-5 and must be available using a diagnostic tool meeting the requirements of ISO DIS 15031-4.
6.5.3.4. When a fault is registered, the manufacturer must identify the fault using the most appropriate fault code consistent with those given in section 6.3 of ISO DIS 15031-6 (SAE J2012 - dated July 1996), relating to '. . . Powertrain system diagnostic trouble codes`. The fault codes must be fully accessible by standardized diagnostic equipment complying with the provisions of 6.5.3.2.
The note in section 6.3 of ISO DIS 15031-6 (SAE J2012 - dated July 1996) immediately preceding the list of fault codes in the same section does not apply.
6.5.3.5. The connection interface between the vehicle and the diagnostic tester must meet all the requirements of ISO DIS 15031-3. The installation position must be subject to agreement of the approval authority such that it is readily accessible by service personnel but protected from tampering by non-qualified personnel.

Unfortunately the directive also has quite specific requirements for anti-tampering measures to prevent the ECU being remapped by unauthorised persons.
Below is the link to the directive, note that there have been amendments:
