The Department of Public Security of the Italian Ministry of the Interior has issued a circular regarding anomalies in the Stoneridge SE5000 Smart 2 Gen2 V2 tachograph that was reported by the manufacturer.

The circular, dated 5th February 2024 and with protocol number 3626, describes the anomalies highlighted on the tachograph event printout, specifically identified by the codes „!1C” and „!0F”.

According to the circular, the „!1C” anomaly indicates an inconsistency between the movement data and the stored data of the driver’s activity, resulting in the display of a „hardware sabotage” message on the tachograph display. 

On the other hand, the „!0F” anomaly is caused by problems with the GNSS satellite navigation system, particularly when it detects a software attack or a navigation data authentication error.

These errors are due to anomalies in the software installed on the tachograph. The circular provides guidelines on how to deal with these anomalies during checks:

  • The „!1C” code should be ignored if it is active for less than thirty minutes. However, if it is active for a longer period, it should only be ignored if the average speed of the vehicle during the day is less than 80 km/h.
  • Similarly, the „!0F” code must be disregarded if it is active for a maximum of 10 minutes.

Importantly, the circular clarifies that events within the specified ranges will not affect the recording of the driver’s activities, as the tachograph will continue to meet the legal requirements set out in the legislation.
