TCS_75If the command is successful, the remaining CHV attempt counter is reinitialised. The initial value of the remaining CHV attempt counter is 5. If the command is successful the card shall set the internal security status ‘PIN_Verified’. The card shall reset this security status, if the card is reset or if the CHV code transmitted in the command does not match the stored reference CHV.
Note: Using the same reference CHV and a global security status prevents that a workshop employee must re-enter the PIN after a selection of another tachograph application DF.
