Air Distribution Motor. Flap Jammed. Note: May set if not calibrated.
Fault symptoms
Perceived temperature in cabin too high or too low compared to the set temperature.
The air distribution does not correspond with the illuminated symbol in the ACC window.
Conditions
The following conditions apply:
• When the stepping motor operates in the range 10-90 % of its total range (which is 0-100 %), the control module senses if the power consumption is above a certain value, and if this is the case, sets the diagnostic trouble code for jammed flap.
• The diagnostic trouble code can be set if the control module has not been calibrated.
• Continuous monitoring and when calibrating.

Conditions
The following conditions apply:
• A short to B+ is indicated when the output for the air recirculation motor is not activated and the voltage on pin 21 exceeds 9 V.
• A short to ground and open circuit is indicated when the output for the air recirculation motor is not activated and the voltage on pin 21 is below 3 V.
• Measured every 440 ms and 5 consecutive measurements are required to set a diagnostic trouble code.
