    Conditions
   
  
  
   The following conditions apply:
   
   
  
  
  
   
    
     
      | • | Open circuit or short to B+ on pin 18 >4.9 V. 
 
 | 
    
   
  
  
   
    
     
      | • | Short to ground on pin 18<0.1 V. 
 
 | 
    
   
  
  
   
    
     
      | • | Measured every 440 ms and 5 consecutive measurements are required to set a diagnostic trouble code. 
 
 | 
    
   
  
  
   
    
     
      | • | The diagnostic trouble code is deleted after the ignition has been switched on 20 times if the malfunction conditions have not been fulfilled. 
 
 | 
    
   
  
  
   
    
     
      | • | When the diagnostic trouble code is set, the control module uses the default value, which is the relative opening of the air-mixing flap in question multiplied by the coolant temperature.
