Documentation Packages
Formal Documentation Package:
The manufacturer may use one formal documentation package for multiple emission type approvals. The formal documentation package shall include the following information:

Point                                                   Explanation

Emission Type Approval Number(s)                        List of emission type approval number(s) covered by this BES-AES declaration:

                                                        including TA reference, software reference, calibration number, checksums of each version and of each relevant Control Unit (CU) such as engine and aftertreatment ones

Method of reading of software and calibration version   E.g. scan-tool explanation

                                                              * Measured and/or modelled parameters for AES activation

  Extended Documentation Package
       The extended documentation package shall include the following information on all AES:

           (a) a declaration of the manufacturer that the vehicle does not contain any defeat device not covered by one of the exceptions in paragraph 5.1.3. of this Regulation;

           (b) a description of the engine and the emission control strategies and devices employed, whether software or hardware, and any condition(s) under which the strategies and devices will not operate as they do during testing for TA;

           (c) a declaration of the software versions used to control these AES/BES, including the appropriate checksums or reference values of these software versions and instructions to the authority on how to read the checksums or reference values; the declaration shall be updated and sent to the type approval authority that holds this extended documentation package each time there is a new software version that has an impact to the AES/BES. Manufacturers may request to use an alternative to a checksum as long as it provides an equivalent level of traceability for software version changes;

           (d) detailed technical reasoning of any AES estimating the impact with the AES and without it, and information on the following:

           (i) why any of the exception clauses from the defeat device prohibition in paragraph 5.1.3. of this Regulation apply;

           (ii) hardware element(s) that need to be protected by the AES, where applicable;

           (iii) proof of sudden and irreparable engine damage that cannot be prevented by regular maintenance and would occur in the absence of the
