Air conditioning
The rear window heating is activated from
Climatronic control unit J255. A message is sent
to convenience system control unit J393 via
CAN-Convenience. This actuates heated rear
window Z1 and sends a CAN bus message to
Climatronic control unit J255 that it has been
switched on. The control unit then activates the
respective LED in the button.
The air conditioning system (both variants) in the
new Audi A6´05 uses the MMI display to display
relevant information. The current MMI display
switches over to the air conditioning menu on
pressing the function switch on Climatronic control
unit J255.
