Repairs

An inspection and eventually a calibration must follow repairs.

Some events or faults, such as power supply disconnection, sensor disconnection, opening of the vehicle unit, and similar can legitimately happen during a repair. Therefore, the vehicle unit does not record those events or faults if a workshop card is inserted in the equipment.

The list of admissible minor maintenance operations not classified as repairs is set by tachograph manufacturers and approved during tachograph type approval.
