*2: If the ambient temperature is approximately -52.9°C (- 63.22°F) or lower, DTC B1412/12 may be output even though the system is normal.
*3: If the check is performed in a dark place, DTC B1421/21 (solar sensor circuit abnormal) may be output even though the system is normal.
*4: The A/C amplifier memorizes the DTC of the respective malfunction if it has occurred for the period of time indicated in the brackets.
*5: for 2ZR-FE
