Timer Operation Condition

When BCM detects driver door is unlocked, the key is not inserted in the ignition key cylinder (key switch
OFF), and ignition knob switch is OFF (with Intelligent Key system), it determines that conditions for inte-
rior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.

When BCM detects key is removed from ignition key cylinder (key switch OFF), it determines that condi-
tions for interior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.

When BCM detects driver door is closed, and the key is not inserted in the ignition key cylinder (key switch
OFF), and ignition knob switch is OFF (with Intelligent Key system), it determines that conditions for inte-
rior room lamp timer operation are met, and turns the room lamp ON for 30 seconds.

When ignition knob turns to OFF from ON, Intelligent Key unit sends ignition knob switch signal
(ON→OFF) through CAN communication. When BCM detect ignition knob switch is turned to OFF by igni-
tion knob switch signal (ON→OFF), and the key is not inserted in the ignition key cylinder (key switch
OFF), it determines that conditions for interior room lamp timer operation are met, and turns the room
lamp ON for 30 seconds.
BCM does not activate the timer even a door other than the driver door is opened.
*: Setting can be changed by CONSULT-II. Refer to LT- 2 3 3 , "
WORK SUPPORT (INT LAMP)" .

of the battery. (Timer setting can be changed by CONSULT-II. Refer to LT- 2 3 4 , "
WORK SUPPORT (BATTERY
SAVER)" .)

When the ignition key switch or ignition knob is turned from ON to OFF, the timer is activated.

When any of the following door switch signal condition is changed with the ignition key switch in OFF posi-
tion, the timer is activated when the change is occurred.
