< FUNCTION DIAGNOSIS >
INTERIOR ROOM LAMP CONTROL SYSTEM
 The interior room lamp turns ON and OFF (gradual brightening and dimming) by the interior room timer.
 BCM judges the vehicle condition with the following items. It activates the interior room timer.
- Ignition switch status
- Door switch signal (ALL)
- Door lock/unlock signal (Remote keyless entry receiver, each request switch, door lock/unlock switch)
NOTE:
Each function of interior room lamp timer can be set by CONSULT-III. Refer to INL-16, "
INT LAMP : CON-
SULT-III Function (BCM - INT LAMP)".
Interior Room Lamp ON Operation
 BCM always turns the interior room lamp ON when any door opens.
 BCM activates the interior room timer in any of the following conditions to turn the interior room lamp ON for
a period of time.
- Any door opens before all doors close.
- Ignition switch is turned ON → OFF.
- Any door unlock signal is detected when all doors close with ignition switch OFF.
NOTE:
Restart the timer if new condition is input during the timer operating time.
Interior Room Lamp OFF Operation
BCM stops the timer in any of the following conditions to turns the interior room lamp OFF.
 The timer operating time is expired.
 Ignition switch position is other than OFF with all doors close.
 Any door lock operation is detected with all doors close.
STEP LAMP CONTROL
BCM controls the step lamp (ground-side) to turn ON with any door switch ON.
TRUNK ROOM LAMP CONTROL
BCM controls the trunk room lamp (ground-side) to turn ON with trunk room lamp switch ON.
PUSH-BUTTON IGNITION SWITCH ILLUMINATION CONTROL
Push-button Ignition Switch Illumination Basic Operation
BCM provides the power supply to turn the push-button ignition switch illumination ON.
Push-button Ignition Switch Illumination ON Operation
BCM turns the push-button ignition switch illumination ON in the following conditions.
 Ignition switch ON
 Any of the following conditions with ignition switch OFF
- Engine start permission is entered.
- Intelligent Key inserted into the key slot.
- Driver door is LOCK → UNLOCK.
- Driver door is open.
Push-button Ignition Switch Illumination OFF Operation
BCM turns the push-button ignition switch illumination OFF in any of the following conditions.
 The push-button ignition switch illumination ON conditions do not satisfy.
 All of the following conditions with ignition switch OFF
- The push-button ignition switch illumination ON conditions do not change (15 seconds after the ignition
switch OFF) or the driver door is UNLOCK → LOCK.

System DescriptionINFOID:0000000003774544
OUTLINE
 Interior room lamp battery saver is controlled by BCM.
 BCM turns applicable lamps OFF depending on the vehicle condition. This function prevents the battery
from over-discharging if the driver neglect turning OFF the any lamps.

INTERIOR ROOM LAMP BATTERY SAVER FUNCTION
 When the ignition switch is turned OFF, BCM operates the timer for a period of time to cut the interior room
lamp power supply.
 BCM restart the timer when any of the following signals changes while operating the timer.
- Ignition switch status
- Door switch signal (ALL)
- Door lock/unlock signal (Remote keyless entry receiver, each request switch, door lock/unlock switch)
- Trunk room lamp switch signal
- Key switch signal (Key slot)
 BCM provides the interior room lamp power supply continuously when the ignition switch position is other
than OFF.
NOTE:
Each function of interior room lamp battery saver can be set by CONSULT-III. Refer to INL-17, "

 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
