Data exchange between control modules, checking: Notes

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2003 Audi S8, 2003 Audi A8, 2002 Audi S8, 2002 Audi A8, and 2001 Audi S8. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Data exchange between individual control modules occurs via a bus system.
  • The term "CAN-bus" refers to a system that transports and distributes data.
  • The wire connections between the control modules, via which data is transferred, are referred to as data wires.
  • Data is transferred to the connected control modules serially (one after the other) across the data wires.
