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.
Interior Temperature Monitoring
The EATC control module monitors the interior temperature through a sensor system consisting of four sensors. Two sensors in the heater housing for monitoring the outlet temperature, one sensor in the EATC control panel to monitor the interior temperature and one sun load sensor in the crash padding to monitor the intensity of the sunlight entering the vehicle. In addition, the EATC control module is supplied with the current external temperature information by the trip computer. On vehicles with a Duratec-ST engine, the EATC control unit is supplied with the current exterior temperature information over the SCP-Bus.
