MODEL 209.3 up to 1.6.03 with CODE (873) Electrically heated left and right front seats
Function prerequisites
- Circuit 15R ON or circuit 15 ON
Function
The switch-on heated seats function can be selected by the left front HS/seat ventilation switch (N72/1s10) or the right front HS/seat ventilation switch (N72/1s11) in the upper control panel control module (N72/1).
Moving the left front HS/seat ventilation switch (N72/1s10) or the right front HS/seat ventilation switch (N72/1s11) upwards activates or deactivates stage 1 of the heated seats (1 LED in the left front HS/seat ventilation switch (N72/1s10) or in the right front HS/seat ventilation switch (N72/1s11) lights red).
Moving the left front HS/seat ventilation switch (N72/1s10) or the right front HS/seat ventilation switch (N72/1s11) downwards activates or deactivates stage 2 of the heated seats (2 LEDs in left front HS/seat ventilation switch (N72/1s10) or in the right front HS/seat ventilation switch (N72/1s11) lights red).
The upper control panel control module (N72/1) actuates the left front seat heated cushion (R13/1) and left front backrest heated cushion (R13/2) or the right front seat heated cushion (R13/3) and right front backrest heated cushion (R13/4), which are heated depending on the selected heating stage.
The circuit status on the electronic ignition switch control module (N73) and the battery voltage are notified via the CAN Class B to the upper control panel control module (N72/1).
The logic for the heated seats is integrated in the in the upper control panel control module (N72/1). A pulsed output, depending on the selected output stage, is outputted to the corresponding heating elements.
See table shown below.
| Operating condition | Heating | duty cycle | Function indicator |
|---|---|---|---|
| Heating stage 1 | Heating stage 1 (Heating duration 30 min. after switch on or switchover, then heated seats OFF) | 33 % | 1 red LED |
| Heating stage 2 | Heating stage 2 (Heating duration 5 min. after switch on or switchover, then heating stage 1) | Output driver at continuous operation | 2 red LEDs |
| Automatic switchover | Switchover from heating stage 2 to heating stage 1 after 5 min., then after 30 min. heated seats OFF | Switchover output driver continuous operation after 33 % | switchover from 2 LEDs red to 1 LED red |
