Look up by industry group
Every ECU in a J1939 network shall have a unique 8 byte identification number, no two devices shall share the same identification number on a given vehicle network. This number includes a vendor-specific number, a function number, a vehicle system number and the industry group number. Because the definition of vehicle systems will vary from one industry to another, the vehicle system definition depends upon the industry group. Also dependent upon the industry group are the function numbers.
Therefore this Product Guide categorizes the products into industry groups based upon their vehicle system definition and their function numbers.
The industry groups are listed on the left side of the screen.
