Interior Lighting Module: Description and Operation

INTERIOR LIGHT
The ETACS-ECU controls the interior lights (dome light and rear personal lights) operation as follows:

NOTE: Interior lights and rear personal light are controlled, only when switch position is set to the position "door controlled operation"

- When a door is opened from outside or inside [with the ignition switch turned to "LOCK" (OFF)]:
- When a door is opened, the ETACS-ECU causes the interior lights to be illuminated at 100% intensity. When the door is closed, it dims the interior lights to 65% intensity and approximately 30 seconds later, turns out the light completely. During this period (timer controlled period), the interior lights goes out if the ignition switch is turned "ON" or the doors are locked.
- When a door is opened or closed with the ignition switch in the "ON" position: The interior lights illuminates at 100% intensity when a door is opened and turned out when it is closed.
- When no door is opened and the ignition key is removed: The interior lights is illuminated at 100% intensity and turned off approximately 30 seconds later. During that time (timer-controlled period), the interior lights goes out if the ignition key is inserted and turned to "ON" or the door locking system is activated.
- Interior lights's answerback operation in response to door lock control by keyless entry system: To allow the driver to confirm the doors have locked by the keyless entry system, the ETACS-ECU causes the interior lights to blink twice when the doors are locked by the RKE system and to illuminate for approximately 30 seconds when the doors are locked. The interior lights's answerback operation in response to a keyless entry system control action is accompanied by flashing of the hazard warning lights.
