DOME LIGHT, FOOT LIGHT AND IGNITION KEY CYLINDER ILLUMINATION LIGHT
CIRCUIT
OPERATION
<Dome light>
l 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.
l 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.
l 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.
<Foot lights and ignition key illumination light>
l Battery voltage is always applied to the foot lights and ignition key illumination light.
With the ignition switch in the OFF position, open any door, and all lights will come on.
l With all lights turned on (with the ignition switch in the OFF position), close all doors, and the timer circuit
inside the ETACS unit will operate in the same manner as the dome light to dim all lights. When the
ignition switch is placed in the ON position with all lights turned on (with the timer in operation), the same
operation as the dome light will take place.
