*1 If the room temp. is approx. -20°C (-4°F) or lower, code 11 may be output even though the system is normal.
*2 If the ambient temperature is approx. -50°C (-58°F) or lower, a malfunction code may be output even though the system is normal.
*3 If the check is being performed in a dark place, diagnostic trouble code 21 (solar sensor circuit abnormal) could be displayed. In this case, perform diagnostic trouble code check again while shining a light, such as an inspection light, on the solar sensor.
If code 21 is still displayed, there could be trouble in the solar sensor circuit.
