Inspection Procedure 4: Radiator Fan and Condenser Fan do not Operate < 3.0 L Engine >: Operation

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

Based on the signal from the engine coolant temperature sensor and the output shaft speed sensor signal (vehicle speed signal) from the TCM, and the A/C switch signal from the A/C-ECU, the ECM sends the radiator fan and condenser fan control signal to the ETACS-ECU via CAN bus line.
Based on the radiator fan and condenser fan control signal from the ECM, the ETACS-ECU turns ON/OFF the radiator fan relay, condenser fan relay, and the fan control relay to control the rotation of the radiator fan motor and condenser fan motor.
