Stepping motor, right-hand air-blending flap |
Calibration takes place by simultaneously pressing the AUTO and REC buttons. A sound and the message, ACC:CALIBR. STARTED are indicated in the main instrument unit, confirming the calibration. Calibration must take place if the battery is disconnected/discharged, if the ACC unit or stepping motor is replaced, or their positions are changed.
The climate system has three air-blending flaps, one for the driver's zone and one air-blending flap for the front seat passenger that is connected via a link with the air-blending flap for the rear seat passengers.
The stepping motor for the right-hand air-blending flap is supplied with current from the ACC unit's K1 pins 34 and 32 (winding 1), and K1 pins 33 and 31 (winding 2).
The flap is set by the control module using the air-blending temperature sensor for the right-hand side so that the requested air-blending temperature is obtained.
In the OFF position the flap stops in the last selected position.
When the ignition is switched off the air-blending flap will first stop in the latest selected position and after 8 minutes it moves to park position, max. cold (0%).
