  1. GENERAL


    1. The air conditioning system has the following features:


      • Based on the signals from the ambient temperature sensor, this system calculates the outside temperature and indicates it in the multi-information display.

      • The Positive Temperature Coefficient (PTC) heater system contains a PTC heater that heats the air that has passed through the heater core to ensure the proper heater performance.

      • Turns the rear defogger and outside rear mirror heaters on for 15 minutes when the rear defogger switch is pressed. Turns them off if the switch is pressed while they are operating.

      • When a high load is applied to the EPS system, the EPS ECU will send a signal to the air conditioning amplifier. After receiving the signal, the air conditioning amplifier may turn off the rear defogger, front deicer, and seat heaters.

  4. A/C FLOW SENSOR

    The A/C flow sensor, which is mounted on the compressor with pulley, is used to detect the amount of refrigerant flow. The A/C flow sensor converts the amount of refrigerant flow that is detected to a voltage value to send it to the A/C amplifier. The voltage value sent from the A/C flow sensor changes depending on the amount of refrigerant flow. As the amount of refrigerant flow becomes larger, the voltage becomes lower. As the amount of refrigerant flow becomes smaller, the voltage becomes higher. The A/C amplifier supplies 5 V to the A/C flow sensor and monitors change in the voltage value sent from the A/C flow sensor. The A/C amplifier then sends a signal to the ECM via CAN communication to allow the ECM to control the engine speed while the air conditioning is on.
