Interior Light

GENERAL DESCRIPTION CONCERNING THE INTERIOR LIGHT

The following ECUs affect the functions and control of the interior lights.






INTERIOR LIGHT

INTERIOR LIGHT CONTROL





The ETACS-ECU controls the interior lights by turning them on and off in the following way:

- When a door is opened with the ignition switch off, the interior lights up to a luminance of 100 percent. When a door is closed, the interior lights dim to a luminance of 65 percent, and go off 30 seconds later. However if the ignition switch is turned ON or if a door is locked while the interior lights are dimming, the dome light will go off at that point.
- When a door is opened with the ignition switch ON, the interior lights up at a luminance of 100 percent. When a door is closed, the interior lights go off.
- When the ignition key is removed with all doors closed, the interior lights up at a luminance of 100 percent, and goes off 30 seconds later. However if the ignition key is inserted again or if a door is locked while the interior lights is lighting, the interior lights will go off at that point.
- To check keyless entry operations more easily, the interior lights flash once when the doors are locked. When the doors are unlocked, the interior lights at a luminance of 100 percent, and go off 15 seconds later.

NOTE:
The dotted lines indicate that lighting mode when the ignition switch is turned ON, door is locked, or any door is opened during the timer illumination time.

Interior light automatic-shutoff function





Illuminated interior lights such as the front dome light, etc. (all lights using the dome light fuse as the power supply) will automatically go off in the following conditions to prevent the battery from discharging as a result of forgetting to turn off the lights or incomplete closing of the door.

- When the ignition switch is turned off and more than 30 minutes pass by with the interior light illuminated, the interior lights will go off automatically.
- When the ignition switch is turned off and one of the door switches remains open for 30 minutes continuously, the interior lights will go off automatically.

Seat belt indicator









If any of the following conditions are met with the ignition switch at "ON" or "ST", the ETACS-ECU illuminates or extinguishes the seat belt indicator by using the driver's seat belt switch signal and the vehicle speed signal from the combination meter.

- The seat belt indicator illuminates when the seat belt switch is turned on (driver's seat belt is not fastened) with the ignition switch "ON.
- Flashes and illuminates the indicator 12 cycles (after 0.5 second) if any of the following conditions are met when 60 seconds or more have elapsed since the ignition switch is turned "ON". One cycle consists of five-second "flash" and then three-second "illuminate".
1. The vehicle speed has reached 8 km/h (5 mph) while the seat belt switch is turned on (driver's seat belt is not fastened) with the ignition switch "ON.
2. The seat belt switch has been turned on (driver's seat belt has not been fastened) for at least 10 seconds while the ignition switch has been turned "ON" and the vehicle speed has been 8 km/h (5 mph) or more.
NOTE:
Once this timer operation has been activated, it will not be activated again until the vehicle speed reduces to 3 km/h (2 mph) or less even if any of the following conditions are met.

- The indicator turns off if the ignition switch or the seat belt switch is turned off (the driver's seat belt is fastened) while the timer operation is active.


DOOR AJAR INDICATOR

The combination meter receives the signal sent from the ETACS-ECU about whether each door is open or closed and turns the door ajar indicator on and off. While the door ajar indicator is illuminated, the door ajar tone alarm function is activated and the door ajar indicator flashes 4 times. If the door remains open even after the 4 warning flashes, the door ajar indicator will be illuminated again. And when the interior light automatic-shutoff function is activated, the door ajar indicator is extinguished.

IGNITION KEY CYLINDER ILLUMINATION FUNCTION

The ignition key cylinder illumination light illuminates when the driver's door is opened with the ignition switch off, and for 30 seconds after the driver's door is closed. It also illuminates for 30 seconds after the ignition key is pulled out. In any case, it goes out when the ignition switch is turned on.

NOTE:
When the ignition key cylinder illumination is extinguished by the interior light automatic-shutoff function, it does not illuminate.
