Function

•  Fogging on the rear window glass is removed by heating the rear window glass using the rear window defogger filaments to vaporize moisture on the window.

Personalization features

•  The rear window defogger operation time setting can be changed (initial setting is 15 minutes). Refer to the [GLASS/WINDOWS/MIRRORS PERSONALIZATION] for details on personalization features. (See GLASS/WINDOWS/MIRRORS PERSONALIZATION.)


Construction

Rear window defogger
•  The rear window defogger filaments are positioned on the cabin side of the rear window glass.

Operation


With full-auto air conditioner system

Rear window defogger operation time is set to 15 minutes
1.  When the rear window defogger switch on the climate control unit is turned on, an ON/OFF control request signal is sent to the front body control module (FBCM) through the instrument cluster as a CAN signal.
2.  When the front body control module (FBCM) receives the ON/OFF control request signal, it supplies the battery voltage to the rear window defogger relay.
3.  When the battery voltage is supplied to the rear window defogger relay, a switch inside the rear window defogger relay is turned on.
4.  When the switch inside the rear window defogger relay is turned on, the battery voltage is supplied to the rear window defogger/heated outer mirrors to operate them.
Note
•  When approx. 15 min have elapsed after the rear window defogger timer started operation, the front body control module (FBCM) turns the rear window defogger relay off and stops the rear window defogger operation.

5.  When approx. 15 min have elapsed since the front body control module (FBCM) received the rear window defogger operation request signal, it receives an ambient temperature signal from the PCM, and if the PCM detects an ambient temperature of 0 °C or less, the front body control module (FBCM) continues supplying power to the rear window defogger relay. (Ambient temperature of 0 degrees C or less detected)
6.  When approx. 15 min have elapsed since the front body control module (FBCM) received the rear window defogger operation request signal, it receives an ambient temperature signal from the PCM, if the PCM detects an ambient temperature of 1 °C or more, the front body control module (FBCM) stops supplying power to the rear window defogger and the rear window defogger operation is stopped. (Ambient temperature of 1 degree C or more detected)
