HINT:
- *1: If the room temperature is approx. -18.6°C (-3.7 °F) or lower, DTC B1411/11 may be output even though the system is normal.
- *2: If the ambient temperature is approx. -52.9°C (-61.4°F) or lower, a malfunction code may be output even though the system is normal.
- *3: If the check is performed in a dark place, DTC B1421/ 21 or B1424/24 (solar sensor circuit abnormal) could be displayed.
- *4: The air conditioning amplifier memorizes the DTC of the respective malfunction that has occurred for a period of the time indicated in the brackets.
