  • Uses the 29 bit CAN identifier
  • Communication between the truck and trailer
  • Provides information about the towed vehicle electronic break system
  • Supports all the application layer standard messages
  • Collection of diagnostic data from the vehicle


  • Supports on various ARM processors
  • Robust APIs which are easy to integrate
  • Porting support for a newer version of the software
