Legislation originating from the EU
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.

Changes to Legislation
Changes and effects yet to be applied by the editorial team are only applicable when viewing the latest version or prospective version of legislation. They are therefore not accessible when viewing legislation as at a specific point in time. To view the ‘Changes to Legislation’ information for this provision return to the latest version view using the options provided in the ‘What Version’ box above.
3.5.2.3 Command with odd instruction byte U.K.
This command variant enables the IFD to read data from an EF with 32 768 bytes or more.
TCS_51A tachograph card which supports EFs with 32 768 bytes or more shall support this command variant for these EFs. A tachograph card may or may not support this command variant for other EFs with the exception of the EF Sensor_Installation_Data see TCS_156 and TCS_160.U.K.
TCS_52 Command Message U.K.
| Byte | Length | Value | Description |
|---|---|---|---|
| CLA | 1 | ‘00h’ | |
| INS | 1 | ‘B1h’ | Read Binary |
| P1 | 1 | ‘00h’ | Current EF |
| P2 | 1 | ‘00h’ | |
| Lc | 1 | ‘NNh’ | Lc Length of offset data object. |
| #6-#(5+NN) | NN | ‘XX..XXh’ | Offset data object: Tag ‘54h’ Length ‘01h’ or ‘02h’ Value offset |
| [F1Le | 1 | 'XXh' | As specified in ISO/IEC 7816-4] |
The IFD shall encode the offset data object's length with a minimum possible number of octets, i.e. using the length byte ‘01h’ the IFD shall encode an offset from 0 to 255 and using the length byte ‘02h’ an offset from ‘256’ up to ‘65 535’ bytes.
[F2In case of T = 0 the card assumes the value Le = ‘ 00h ’ if no secure messaging is applied.
Textual Amendments
In case of T = 1 the processing state returned is ‘ 6700 ’ if Le= ‘ 01h ’ .]
TCS_53 Response Message U.K.
| Byte | Length | Value | Description |
|---|---|---|---|
| #1-#L | L | ‘XX..XXh’ | Data read encapsulated in a discretionary data object with tag ‘53h’. |
| SW | 2 | ‘XXXXh’ | Status Words (SW1,SW2) |
If the command is successful, the card returns ‘9000’.
If no EF is selected, the processing state returned is ‘6986’.
If the security conditions of the selected file are not satisfied, the command is interrupted with ‘6982’.
If the Offset is not compatible with the size of the EF (Offset > EF size), the processing state returned is ‘6B00’.
If the size of the data to be read is not compatible with the size of the EF (Offset + Le > EF size) the processing state returned is ‘6700’ or ‘6Cxx’ where ‘xx’ indicates the exact length.
[F1If an integrity error is detected within the file attributes, the card shall consider the file as corrupted and unrecoverable, the processing state returned is ‘ 6400 ’ or ‘ 6500 ’.]
If an integrity error is detected within the stored data, the card shall return the demanded data, and the processing state returned is ‘6281’.
3.5.2.3.1 Command with secure messaging (example) U.K.
The following example illustrates the usage of secure messaging if the security condition SM-MAC-G2 applies.
TCS_54Command messageU.K.

| P2 | 1 | ‘00h’ | |
| Lc | 1 | ‘XXh’ | Length of the secured data field |
| #6 | 1 | ‘B3h’ | Tag for plain value data encoded in BER-TLV |
| #7 | 1 | ‘NNh’ | LPV: length of transmitted data |
| #(8)-#(7+NN) | NN | ‘XX..XXh’ | Plain Data encoded in BER-TLV, i.e. the offset data object with tag ‘54’ |
| #(8+NN) | 1 | ‘97h’ | TLE: Tag for expected length specification. |
| #(9+NN) | 1 | ‘01h’ | LLE: Length of expected length |
| #(10+NN) | 1 | ‘XXh’ | Expected length specification (original Le): Number of bytes to be read |
| #(11+NN) | 1 | ‘8Eh’ | TCC: Tag for cryptographic checksum |
| #(12+NN) | 1 | ‘XXh’ | LCC: Length of following cryptographic checksum ‘08h’, ‘0Ch’ or ‘10h’ depending on AES key length for Generation 2 secure messaging (see Appendix 11 Part B) |
| #(13+NN)-#(12+M+NN) | M | ‘XX..XXh’ | Cryptographic checksum |
| Le | 1 | ‘00h’ | As specified in ISO/IEC 7816-4 |
TCS_55Response message if the command is successfulU.K.
| Byte | Length | Value | Description |
|---|---|---|---|
| #1 | 1 | ‘B3h’ | Plain Data encoded in BER-TLV |
| #2 | L | ‘NNh’ or ‘81 NNh’ | LPV: length of returned data (=original Le). L is 2 bytes if LPV>127 bytes. |
| #(2+L)-#(1+L+NN) | NN | ‘XX..XXh’ | Plain Data value encoded in BER-TLV, i.e. data read encapsulated in a discretionary data object with tag ‘53h’. |
