3) The European Type Approval Exchange System (‘ETAES’) is a software application accessible via the internet and developed by the Member States in order to assisting the EU type-approval authorities with the practical implementation of information exchange requirements laid down in Union acts by providing a centralised communication mechanism to facilitate cross-border exchange of a copy of the EU type-approval certificate together with the attachments. A similar system, the Database for the Exchange of Type Approval documentation and information system, has been established under the auspices of the United Nations Economic Commission for Europe. It is therefore appropriate to designate ETAES as the common secure electronic exchange system referred to in Article 27(3) of Regulation (EU) 2018/858.

(4) To preserve confidential data, requirements on access to ETAES and the use of secure data exchange protocols should be laid down.

(5) In order to make ETAES a searchable online database, requirements regarding the upload of the EU type-approval documents referred to in Article 27(1) of Regulation (EU) 2018/858 should be laid down.

(6) In order to better establish the different access rights to ETAES, approval authorities should upload the documents referred to in Article 27(1) of Regulation (EU) 2018/858 in ETAES separately on the basis of their nature and, where relevant, their status.

(7) Considering that ETAES is, in its current version, a communication tool for administrative cooperation between Member States that is not open to the public, it is necessary to harmonise the format and content of the lists referred to Article 12(4) of Regulation (EU) 2018/858 to ensure that the relevant information is made accessible to the public.

(8) The empowerments laid down in the second subparagraph of Article 12(4) and in Article 27(3) of Regulation (EU) 2018/858 set out the requirements for the use of the common secure electronic exchange system of EU type-approval information for motor vehicles and their trailers, and for systems, components and separate technical units intended for such vehicles. As those empowerments are closely linked by their subject matter, they should be bundled for the purposes of this Regulation.

(9) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor Vehicles (TCMV)
