Master function for terminal 15 across the powertrain CAN-bus
As in the Audi A3 ´04, information transmitted across the powertrain CAN bus includes a run-on function.
This allows the various control units to transmit information relevant to safety even when the ignition is off.
With regard to terminal 15 run-on, there are three different groups of powertrain CAN bus control units:
Active and passive control units as well as control units without run-on.
Active control units are control units which are able to keep the powertrain CAN bus awake.
Passive control units remain awake until the gateway signals it is ready to enter Sleep mode, but cannot
independently keep the powertrain CAN bus awake.
Control units without run-on function shut off immediately after "ignition off".
