New Global Circuit Numbering System 2005-01-1734

The New Global Circuit Numbering System (NGCNS) changes the way we do business. It leverages the synergies between the powerful engineering design tools (CAD/CAE) and service diagnostic tools, improving vehicle service and customer satisfaction. NGCNS will provide a clear concise systematic way to identify circuits in vehicle schematics from the Engineer to the Service Technician. NGCNS was developed with input from the Service Technicians, Engineers, and Wire Harness Suppliers from around the world. It defines the circuit number based on the Potential, System, Sub-system and Function (PSF) of the respective portion of the circuit. The color of the wire helps the technician to quickly determine the correct diagnostic voltage by indicating constant voltages (i.e. power and ground) with a color and the function with a second color.

NGCNS is being implemented globally throughout the Ford enterprise and will begin to show up at dealers in 2005.
