GENERAL
The window defogger wires are attached to the inside of the back window glass and defog the window surface quickly when the window defogger switch on the air conditioning control assembly is pressed. The indicator light illuminates while the system is operating. The system automatically turns off after approximately 15 minutes.
Note
If the battery voltage becomes low, window defogger operation is canceled to prioritize supplying power to the power steering system.
FUNCTION OF MAIN COMPONENT
| Component | Outline |
|---|---|
| Air Conditioning Control Assembly | Sends signals to the air conditioning amplifier assembly to operate the window defogger system. |
| Air Conditioning Amplifier Assembly | Sends the window defogger switch signal from the air conditioning control assembly to the main body ECU (multiplex network body ECU). |
| Main Body ECU (Multiplex Network Body ECU) | Sends the window defogger switch signal from the air conditioning amplifier assembly to the No. 3 semiconductor power integration ECU. |
| No. 3 Semiconductor Power Integration ECU | Heats the window defogger wire according to the window defogger switch signal sent from the main body ECU (multiplex network body ECU). |
| Back Window Glass (Window Defogger Wire) | The window defogger wire is heated according to air conditioning amplifier assembly control. |
