Data exchange between Transmission Control Module (TCM) and CAN-capable control modules, checking: Notes

NOTE:
  • The exchange of data between the individual control modules is carried out by means of a bus system.
  • "CAN Bus" describes a system to carry and distribute data.
  • The wiring connections between the control modules, over which the data are transmitted, are described as data lines.
  • Data are transmitted serially, that means in sequence, over these data lines to the attached control modules (e.g. engine RPM, accelerator pedal position).
