Warning

<<High voltage>>

•  If the necessary measures are not taken before servicing an electric vehicle, it could cause electrical shock and result in serious injury or, in the worst case, death. Before servicing the electric vehicle, refer to [HIGH VOLTAGE SERVICE CAUTIONS] in the general information and implement the necessary measures. (See HIGH VOLTAGE SERVICE CAUTIONS.)

Malfunction symptom	Heating not functioning effectively
Details	•  Insufficient warmed-airflow even if airflow temperature setting is MAX HOT •  It takes time for airflow to be warmed to set temperature
Possible Cause	Note •  The electric compressor does not operate during heating operation when the ambient temperature is -20 °C {-4 °F} or less or 25 °C {77 °F} or more. When the temperature is -20 °C {-4 °F} or less, heating is performed using the PTC heater. •  Air mix actuator malfunction •  Blower unit or air filter clogging •  Blower system malfunction •  Cooling fan operation malfunction •  Active air shutter malfunction •  Malfunction of 2way valve for refrigerant •  Malfunction of 3way valve for refrigerant •  PTC heater malfunction •  Heat pump control unit malfunction Caution •  Because the heat pump system does not operate at an ambient temperature of -20 °C or less, remove any snow and frost from the front end of the vehicle before starting the diagnosis.
