INTERIOR LAMP BATTERY SAVER CONTROL
If an interior lamp is left ON and does not turn OFF even when the doors are closed, the BCM turns off power
to the interior lamps automatically to save the battery 30 minutes after the ignition switch is turned OFF.
The BCM controls power and ground to all interior lamps.
After the battery saver system turns the lamps OFF, the lamps will illuminate again when
• a signal is received from an Intelligent Key or main power window and door lock/unlock switch, or when the
front door lock assembly LH (key cylinder switch) is locked or unlocked
• a door is opened or closed
• the Intelligent Key is removed from or inserted into the ignition switch.
The Interior lamp battery saver control time period can be changed with the function setting of CONSULT-III.
