Notes for display field 2:
- Heated front windows are currently not installed, possible as an option at a later time.
- If vehicle is not equipped with heated front window and -J505-, "not installed" or "0" or "00" is shown.
- As long as the voltage on Heated Windshield Control Module -J505- is greater than 12 7 volt and the control module is not too hot, the Heated Windshield Control Module -J505- switches approximately battery voltage to the output for A/C Control Head -E87-
- In the event that the heated front window is switched on, the A/C Control Head -E87- activates a transistor, which cut's the voltage on connector -B- terminal 2 in half. The Heated Windshield Control Module -J505- switches the heated front window on
- If, during the heating operation of front window the voltage (vehicle voltage on -J505-) drops below 12.7 volt or -J505- is getting too hot, a switch opens in -J505- and the voltage at the output to A/C Control Head -E87- will be less than 5 volt, the -J505- switches the heated front window off simultaneously.
- The function and checking procedure is not described, since the Heated front window -Z2- application remains as an open option. Information on function and checking procedures can be identified under:
See Audi A8 1997 > Climate control system
See Audi A4 2002 > Climate control system
