Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Humidity Sensor (Only EEC)
The humidity sensor is directly connected to the climate control module (CCM). The sensor is included in the option system for air quality together with the air quality sensor (AQS)and a particle filter. The main task of the system is to ensure that the air in the passenger compartment is free from pollutants. The task of the humidity sensor is to supply the climate control module (CCM) with information about the current humidity in the passenger compartment.
The climate control module (CCM), via LIN-communication to the humidity sensor, also controls the anti-dazzle function of the interior rear view mirror when back-up (reverse) gear is engaged (applies to the V70).
