Dome Lamp: Description and Operation

- Battery voltage is always applied to the dome light. When the dome light switch is turned to "ON", the dome light will remain lit. After either door is opened if the dome light switch is at "DOOR" position, the dome light will come on.
- With the dome light turned on (with the ignition switch in the OFF position and with the dome light switch in the DOOR position), close all doors, and the timer circuit in the ETACS unit will be activated to gradually vary the voltage for Approx. 6 Seconds owing to the duty control, and the voltage will be output to transistor Tr. Since the voltage applied to the dome light gradually decreases, the dome light will be dimmed.
- If the ignition switch is turned to "ON" while the dome light is lit (while the timer is activated), the timer circuit will be opened to turn "OFF" transistor Tr. This will immediately turn off the dome light without dimming.
