11.12.3.1 Working Principle

The defrost button located on the air-conditioning control panel
sends defrosting request signals to the air-conditioning control
module. air-conditioning control module receives the defrosting
signal and then send it to the BCM. BCM controls the rear
window defroster grille and the left and right rearview mirror
heaters.

BCM monitor the voltage signal. When the battery voltage is
greater than 10.7 V, and the ignition lock switch is at "ON", it
allows the rear defroster / heated mirrors to work. When the
battery voltage is less than 10.3 V, BCM does not allow the rear
defroster / heated mirrors to work.

The rear defroster / rearview mirror heating switch is a push
button switch. After pressing the defrost / mirror heating switch,
the rear defroster / heated mirrors work for 12 min; if the heating
switch is pressed again during heating, the heating stops.
Press the rear defrost / mirror heating switch again, the rear
defroster / heated rearview mirror work 12 min (accumulative
run 12 min) stops. The reset time parameter is 36 min. Before
the 36 min, the heating time is not accumulative.

In the low voltage status, the rear defroster / heated rearview
mirror do not work. but previous timer (12 min) will not be
interrupted and will still be included in the next cycle. The rear
defroster / heated mirror working signal is sent to the ECM
through a dedicated circuit. ECM increase the engine speed
according to the demand.
