This code appears when an issue is found with the date links when reading the tachograph card in drawer 2.
Code 67 points to a potential issue with the tachograph card’s data structure. It does not automatically mean tampering — but it does require attention and proper checks.
Drivers should:
– Remove and reinsert the card to rule out a temporary read error.
– Check the card for visible damage (chips, cracks, contamination).
– If available, try the card in another vehicle unit to confirm whether the issue follows the card.
If the error remains after basic checks:
– The card should be assessed.
– Further technical analysis should be carried out by an approved tachograph centre.

As always, ensure drivers are trained to report fault codes immediately and not ignore operational messages. Early reporting protects both the driver and the operator.
