Adaptation Channel 08, Fresh Air Blower RPM Decrease
Adaptation Of Fresh Air Blower RPM Decrease, Performing (Adaptation Channel 08)
NOTE:
- The fresh air blower speed is lowered so that the speech recognition and speech input of the telephone can be understood better:
- The speed decrease comes in affect, as soon as "Telephone speech input" information is sent via the CAN-bus comfort system.
- The time of speed decrease is limited to a maximum of 2 minutes.
- The amount of fresh air blower speed that will be decreased, depends on the direction of air and of the fresh air blower RPM when the "Telephone speech input" signal occurs. As more air is directed to the instrument panel vents, the fresh air blower speed is decreased.
- The fresh air blower-RPM decrease comes in affect when approximately 40% of air is directed to the instrument panel vents, the maximum decrease occurs at 100% of air at the instrument panel vents.
- In "Basic setting" the fresh air blower speed of 100% air to the instrument panel vents is limited to 15% of maximum fresh air blower RPM. This limit can be lowered or increased via the "Adaptation" function in adaptation channel "8".
- To avoid repeat visits by the customer, after the adaptation has been changed it is reasonable to talk to the customer about the functioning of the speech input function and how it relates to the fresh air blower speed decrease (i.e. 100% air to instrument panel vents) and test if necessary.
Carry out adaptation
- Check DTC memory of A/C control head -E87- and eliminate all displayed malfunctions. Displaying & Reading Trouble Codes
- Check coding of A/C control head -E87- for vehicle equipment options and correct if necessary. Code Control Module (Function 07)
Indicated on display of VAS 5051:
- Select "Adaptation" function 10.
Indicated on display of VAS 5051:
- Display field -1- indicates the request to input channel number.
- Display field -2- shows input keyboard.
- Input via the keyboard -8- for channel "8" in display field -2- and accept by pressing the -Q-button.
NOTE:
- If "Function is unknown or cannot be carried out at the moment" is displayed in display field -1-, the following may be the cause:
- The control module adaptation has not been carried out according to specification and was not completed.
- The CAN-bus comfort system has a malfunction.
Indicated on display of VAS 5051:
- Display field -1- indicates "Channel 8 read and test".
- In area -2- appears e.g. "15%".
- In area -3- appears a scroll bar with a characteristic number for the currently valid maximum fresh air blower speed (e.g. "3840" for "15%").
- Using the scroll bar you can change the fresh air blower speed during telephone operation between 15% - 88%.
NOTE:
- If a characteristic number that corresponds to a maximum fresh air blower speed of smaller than 15% or greater than 88% has been entered via the scroll bar, the characteristic number will be displayed but it will not be implemented.
- If the scroll bar is moved above a characteristic number greater than approx. "32600", the display jumps automatically back to 15%.
- In area -2- appears the new adjusted value for maximum fresh air blower speed during telephone operation
Basic setting at manufacturer: 15% (current characteristic number "3840")
Adjustable maximum fresh air blower speed during speech recognition: 15% - 88% (current characteristic number "3840" - "22528")
The input can also be carried out using the keyboard
- Touch button -4- (input via keyboard)
Indicated on display of VAS 5051:
- In display field -1- appears the display "input adaptation value": 0....XXXXX".
- Display field -2- shows input keyboard.
- Input via the keyboard in the display field the value for the desired maximum fresh air blower speed in function "Speech input-telephone" for the new adaptation of the A/C control head -E87-.
Basic setting at manufacturer: 15% (current characteristic number "3840")
Adjustable maximum fresh air blower speed during telephone operation: 15% - 88% (current characteristic number "3840" - "22528")
NOTE:
- At 88% adjustment the fresh air blower speed will not be lowered anymore. With this adjustment the speech recognition and the understandability of the speech input of the phone at maximum fresh air blower speed and the air direction to the dash panel vents may have interferences.
- If a characteristic number that corresponds to a maximum fresh air blower speed of smaller than 15% or greater than 88% has been entered via the keyboard, the characteristic number will be displayed but it will not be implemented.
- If the characteristic number greater than approx. "32600" has been entered with keyboard, the display jumps automatically back to 15%.
- The fresh air blower-RPM decrease comes in affect when approximately 40% of air is directed to the instrument panel vents, the maximum decrease occurs at 100% of air at the instrument panel vents.
- The entered characteristic number is displayed in area -2-.
- Press -Q-button to confirm input.
Indicated on display of VAS 5051:
- In area -2- appears the newly adjusted value for the maximum fresh air blower speed during telephone operation.
- The entered characteristic number appears in area -3- above the scroll bar.
- Save input by touching button -5-.
Indicated on display of VAS 5051:
- Display field -1- indicates "Channel 8 save".
- In area -2- appears the newly adjusted value for the maximum fresh air blower speed during telephone operation.
- In area -3- appears the original and new adjusted value for maximum fresh air blower speed during telephone operation
- Accept and save input by touching button -5-.
- Display field -1- indicates "Channel 8 save, value 0 - XXXX saved".
NOTE:
- If a characteristic number has been entered that corresponds to a maximum fresh air blower speed of smaller than 15% or greater than 88%, the characteristic number will be displayed but will not be implemented.
- If a characteristic number of approx. "32600" is entered, the characteristic number is not considered by A/C control head -E87- and 15% will be saved.
- By clicking the <- button you will return to the selection menu.
- Check speech recognition with the newly entered decreased fresh air blower speed.
- End On Board Diagnostic (OBD) and switch ignition off. End Output (Function 06)
Check speech input and speech recognition of telephone as follows
- Start engine.
- Select on A/C control head -E87- the function "Maximum fresh air blower speed" and "Air distribution to dash panel vents" or "Defrost" function.
- Open all dash panel vents
- Check function of speech input and speech recognition of the telephone with this adjustment.
