Adaptation of fresh air blower RPM decrease, performing (adaptation channel 08): Notes

NOTE:

To improve voice recognition and the clarity of telephone voice input, the Fresh Air Blower speed is reduced on vehicles as of Model Year 2002 (with operating and display module, Climatronic Control Module J255 as of hardware/software version "0711").
The reduction takes effect as soon as the message "Telephone voice input" is transmitted via the CAN-Bus comfort system.
The reduction time is limited to max. 2 minutes.
The amount by which the Fresh Air Blower speed is reduced depends on the air outflow direction and the Fresh Air Blower speed when the "Telephone voice input" signal is received. The greater the proportion of air routed to the instrument panel vents, the more the speed is reduced.
Reduction of the Fresh Air Blower speed takes effect as of approx. 40% air distribution to the instrument panel vents. The maximum reduction takes place with 100% air to the instrument panel vents.
In the basic setting, the Fresh Air Blower speed with 100% air to the instrument panel vents is limited to 15 % (or 25 %) of the maximum Fresh Air Blower speed depending on the version of the operating and display module, Climatronic Control Module J255. This restriction can be reduced or cancelled via the "Adaptation" function in adaptation channel "8".
To obviate the need for several workshop visits, it is appropriate after changing the adaptation to discuss the "Voice input" function with customers on vehicle hand over with regard to the desired reduction of the Fresh Air Blower speed with 100% air from the instrument panel vents and to try this out if applicable.
