Heated Glass Element: Description and Operation

- If the defogger switch is turned to "ON" when the generator is generating electricity (L terminal exceeds 10 V.) with the ignition switch at the "ON" position, the timer circuit in the ETACS unit will be operated to keep the transistor "on" for 11 Minutes to close the contact point of the defogger relay. When the defogger relay is "on", the defogger and mirror heater will be activated. Moreover, the indicator light of the defogger switch is lit to inform that the defogger and mirror heater are activated.
- When 11 Minutes have passed, the defogger and mirror heater will stop activating even if the defogger switch is at "ON". When the defogger and mirror heater are activated (the timer is activated), they will also stop activating even if the defogger switch is set at "ON" again or if the generator stops generating electricity (the terminal is 3.5 V or less.)

NOTE: The light automatic shut-off system is valid for the illumination light of the defogger switch. Description and Operation
