-Standard cruise control actually involves the CAN bus less than you would expect - Wheel speed data comes from the ABS module via the bus, and the button states come from the bus, but that's about it. The engine does everything else on it's own, except possibly sending gear requests to a separate transmission (sometimes the PCM handles engine and trans, sometimes there's a separate TCM for the trans).

-Due to the fault-intolerant nature of airbags, they rarely use the CAN bus. To my knowledge, the safety ECU communicates directly with everything it requires (although some satellite sensors use a dedicated sensor bus).[/QUOTE]

I suppose Wikipedia was not the best source for information.
