ROOM LAMP TIMER OPERATION
When lamp switch is in DOOR position and all conditions below are met, BCM performs timer control (maxi-
mum 30 seconds) for interior room lamp and map lamp ON/OFF.
Power is supplied
• through 10A fuse [No. 19, located in the fuse block (J/B)]
• to key switch and key lock solenoid terminal 3.
Key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM terminal 37.
Serial data is supplied
• to BCM terminal 22
• through main power window and door lock/unlock switch terminal 14.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp and map lamp timer operation conditions are met, and turns the interior room lamps ON for 30 sec-
onds.
Key is in ignition key cylinder (key switch ON), power is supplied
• through key switch and key lock solenoid terminal 4
• to BCM terminal 37.
When key is removed from key switch and key lock solenoid (key switch OFF), power supply to BCM terminal
37 is terminated. BCM detects that key has been removed, determines that interior room lamp and map lamp
timer conditions are met, and turns the interior room lamps ON for 30 seconds.
When front door LH opens → closes, and the key is not inserted in the key switch and key lock solenoid (key
switch OFF), BCM terminal 47 changes between 0V (door open) → 12V (door closed). The BCM determines
that conditions for interior room lamp operation are met and turns the interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
• Front door LH is locked [when locked by keyfob, main power window and door lock/unlock switch, or front
door lock assembly LH (key cylinder switch)]
• Front door LH is opened (front door switch LH turns ON)
• Ignition switch ON.
