GME GMI 12554 R PART 1 PDF

This specification, referred to as the GM1 12554, Part 1, defines the general requirements for electrical signals and interfaces of the electrical system in cars developed by GMIO. In the past, such requirements have typically been taken care of by component wise specifications, unfortunately not very unified or standardised. This fact has caused compatibility problems, e.g. when creating new variants of the electrical components involved.
