calculates an air flow value based on the speed of the car, air and blending flap position.
With manual selection of defrost or HI, 6 fan steps are shown. With selection of LO, 8 fan steps are shown which is MAX fan speed. Required fan speed
can also be selected manually on the panel. If fan speed 0 is selected then the A/C will be disengaged, but otherwise the ACC system is fully active.
Fan speed is shown with a number of positions by the ACC unit knob.
Adjustment
With the diagnostics tool, the ACC unit can be adjusted to delay fan engagement if there is a risk of mist forming on the inside of the windscreen. This
occurs if the engine has been turned off for more than 1 minute and the outside temperature is between 0 degree C and 15 degrees C.
The delay period can be set to between 0 and 30 s.
Diagnostics
In the event of short circuit in the control circuit diagnostic trouble code B2425 is generated.
