Regulation (EU) No 165/2014 of the European Parliament and of the CouncilShow full title

Article 22 Installation and repair

1. Tachographs may be installed or repaired only by fitters, workshops or vehicle manufacturers approved by the competent authorities of the Member States for that purpose in accordance with Article 24.

2. Approved fitters, workshops or vehicle manufacturers shall, in accordance with the specifications included in the type-approval certificate referred to in Article 15, seal the tachograph after having verified that it is functioning properly, and, in particular, in such a way as to ensure that no manipulation device can tamper with or alter the data recorded.

3. The approved fitter, workshop or vehicle manufacturer shall place a special mark on the seals which it affixes and, in addition, for digital tachographs, shall enter the electronic security data for carrying out authentication checks. The competent authorities of each Member State shall send to the Commission the register of the marks and electronic security data used and the necessary information related to the electronic security data used. The Commission shall give Member States access to that information upon request.

4. For the purpose of certifying that the installation of the tachograph took place in accordance with the requirements of this Regulation, an installation plaque shall be affixed in such a way as to be clearly visible and easily accessible.

5. Tachograph components shall be sealed as specified in the type-approval certificate. Any connections to the tachograph which are potentially vulnerable to tampering, including the connection between the motion sensor and the gearbox, and the installation plaque where relevant, shall be sealed.

A seal shall be removed or broken only:

• by fitters or workshops approved by the competent authorities under Article 24 for repair, maintenance or recalibration purposes of the tachograph, or by control officers properly trained and, where required authorised, for control purposes;

• for the purpose of vehicle repair or modification which affects the seal. In such cases, a written statement stating the date and time at which the seal was broken and giving the reasons for the seal removal shall be kept on board the vehicle. The Commission shall develop a standard form for the written statement through implementing acts.

In all cases, the seals shall be replaced by an approved fitter or workshop without undue delay and at the latest within seven days of their removal.

Before replacing seals, a check and calibration of the tachograph shall be performed by an approved workshop.
