INTERIOR ROOM LAMP BATTERY SAVER SYSTEM : System Description
INFOID:0000000010122262
SYSTEM DIAGRAM
OUTLINE
• Interior room lamp battery saver is controlled by BCM.
• BCM turns applicable lamps OFF depending on the vehicle condition. This function prevents the 12V battery
from over-discharging if the driver neglects turning OFF the lamps.
Applicable lamps:
• Map lamp
• Room lamp
• Luggage room lamp
INTERIOR ROOM LAMP BATTERY SAVER FUNCTION
• When the power switch is turned to other position than ON, BCM operates the timer for a period of time to
cut the interior room lamp power supply.
• BCM restarts the timer when any of the following signals changes while operating the timer:
- Power switch status
- Door switch signal (ALL)
- Door lock/unlock signal (remote keyless entry receiver, each door request switch, door lock and unlock
switch, door key cylinder switch)
• BCM provides the interior room lamp power supply continuously when the power switch position is ON.
NOTE:
Each function of interior room lamp battery saver can be set by CONSULT. Refer to

ILLUMINATION CONTROL SYSTEM : System Description
INFOID:0000000010122263
SYSTEM DIAGRAM
OUTLINE
Each illumination lamp is controlled by each function of BCM and IPDM E/R.
Control by BCM
• Combination switch reading function
• Headlamp control function
Control by IPDM E/R
• Relay control function
Control by combination meter
• Meter illumination control function (Refer to
MWI-8, "METER SYSTEM : System Description"
ILLUMINATION CONTROL
• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits position light request signal to IPDM E/R and combination meter according to tail lamp ON
condition.
Tail lamp ON condition:
- Lighting switch 1ST
- Lighting switch 2ND
- Lighting switch AUTO, and the auto light function ON judgment
- Lighting switch AUTO, with the front fog lamp switch ON and the power switch ON
• IPDM E/R turns the integrated tail lamp relay ON according to position light request signal. It provides the
power supply to each illumination lamp.
• Combination meter enters in the nighttime mode according to position light request signal. Under the night-
time mode the combination meter controls the illuminance by controlling each illumination lamp (ground
side).

Auto light adjustment system is controlled by each function of BCM and combination meter.
Control by BCM
• Auto light system
• Auto light adjustment system
AUTO LIGHT ADJUSTMENT SYSTEM
Description
• BCM supplies voltage to the optical sensor when the power switch is turned ON or ACC.
• Optical sensor converts outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
• BCM judges dimming/brightening of combination meter and display according to brightness outside the vehi-
cle, when power switch is ON.
• BCM transmits dimmer signal to combination meter via CAN communication, according to auto light adjust-
ment conditions.
NOTE:
As to dimming/brightening timing, the sensitivity depends on settings. The settings can be changed with CON-
SULT. Refer to
BCS-17, "HEADLAMP : CONSULT Function (BCM - HEAD LAMP)"
