Front Defroster Control Operation
European (L.H.D. U.K.) specs.
-
• The operation is the same as that of the PREMACY. (See PREMACY Training Manual 3336-1*-99C)
Australian, General (L.H.D.) specs.
-
• When the airflow mode selector dial is turned to DEFROSTER position, a wire moves the airflow mode link, turning the airflow mode to DEFROSTER.
-
• The microswitch turns on at the same time, and the CPU sends a signal to turn the air intake mode to FRESH and A/C to ON.
-
• The air intake actuator operates and turns the air intake mode to FRESH.
-
• The thermosensor sends the A/C ON signal to the PCM based on the signal of the CPU, and turns A/C on.
