Commission Implementing Regulation (EU) 2016/799 of 18 March 2016 implementing Regulation (EU) No 165/2014 of the European Parliament and of the Council laying down the requirements for the construction, testing, installation, operation and repair of tachographs and their components (Text with EEA relevance) (c. 799)

ANNEX I C Requirements for construction, testing, installation, and inspection

6.CHECKS, INSPECTIONS AND REPAIRS

6.4 Periodic inspections

(409)Periodic inspections of the equipment fitted to the vehicles shall take place after any repair of the equipment, or after any alteration of the characteristic coefficient of the vehicle or of the effective circumference of the tyres, or after equipment UTC time is wrong by more than 20 minutes, or when the VRN has changed, and at least once within two years (24 months) of the last inspection.

(410)These inspections shall include the following checks:

that the recording equipment is working properly, including the data storage in tachograph cards function and the communication with remote communication readers,
that compliance with the provisions of chapter 3.2.1 and 3.2.2 on the maximum tolerances on installation is ensured,
that compliance with the provisions of chapter 3.2.3 and 3.3 is ensured,
that the recording equipment carries the type approval mark,
that the installation plaque, as defined by Requirement 396, and the descriptive plaque, as defined by Requirement 225, are affixed,
the tyre size and the actual circumference of the tyres,
that there are no manipulation devices attached to the equipment,
that seals are correctly placed, in good state, that their identification numbers are valid (referenced seal manufacturer in the EC database) and that their identification numbers correspond to the installation plaque markings (see requirement 401).

(411)If one of the events listed in Chapter 3.9 (Detection of Events and/or Faults) is found to have occurred since the last inspection and is considered by tachograph manufacturers and/or national authorities as potentially putting the security of the equipment at risk, the workshop shall:

make a comparison between the motion sensor identification data of the motion sensor plugged into the gearbox with that of the paired motion sensor registered in the vehicle unit;

check if the information recorded on the installation plaque matches with the information contained within the vehicle unit record;

check if the motion sensor serial number and approval number, if printed on the body of the motion sensor, matches the information stored in the recording equipment data memory;

compare identification data marked on the descriptive plaque of the external GNSS facility, if any, to the ones stored in the vehicle unit data memory;
