The first edition of the standard ISO 7638 was issued in 1985. Its purpose was to create a standardized system for the transfer of signals regarding the anti-lock braking system (ABS) from towing vehicles to heavy trailers. In 1997, the standard was split into two parts with ISO 7638-1 covering 24V systems and ISO 7638-2 covering 12V systems. The next review was issued in 2003. It updated the previous edition concenring requirements for the connection of running gear. The latest version of the two-part standard is from 2018.
