Parking Heater

NOTE: "OFF" cannot be selected while the parking heater is activated. This means that the selection can only be cancelled by cancelling the selection at the timer switch or by switching on the ignition.

Activation of the parking heater is selected with a time switch that supplies pin 3 on the ACC control module with 12 V. The ACC control module sends a 12 V wake-up signal from pin 4 to the EDU control module, which sends information about outside temperature in the form of a sequence of impulses back to pin 18 on the ACC control module. Provided the ignition is off, this results in the following selections:
- Air mixing damper function - Normal
- Air distributor function - Normal
- Air recirculation flap:
100% recirculation when outside temperature is bellow -10°C (14°F)
100% fresh air when outside temperature is over -10°C (14°F)
- Ventilation fan motor current - 5.5 A
- Electrically heated rear window and electrically heated door mirrors - OFF
- Rear door fans - OFF
- Display - Normal function
- LEDs - Normal function
- Push-buttons: all manual selections except "OFF"; control of the fan speed are possible.
