GMW15862 Format (To be phased in per GMW15862) 
A description of each field follows:
Line Identification (Line Id)
The Line Identifier is a 1 byte field (starting at byte 1 of the DID) that is used to indicate the component
assembly line.
Shift Identification 1, 2 or 3 (Shift Id)
This is a one byte field (starting at byte 2 of the DID) that identifies the shift that assembled the
component.
Last Two Digits of Year (Year)
This is a two byte field (starting at byte 3 of the DID) that contains the last two digits of the year that the
component was assembled.
Day Of the Year (Day)
This is a three byte field (starting at byte 5 of the DID) that contains the Julian day of the Year that the
component was assembled.
Traceability Number
This value is a supplier assigned serial, lot or batch number. This field starts at byte 8 of the DID and is
up to 9 bytes in length. The content is assigned by the module manufacturer. If less than 9 characters
are required to uniquely identify an ECU, then the leading characters shall be filled with zeroes (0x30).
