System DescriptionEKS003BQ
POWER SUPPLY AND GROUND
Power is supplied at all times:
lthrough 10A fuse [No. 28, located in the fuse block (J/B)]
lto key switch terminal 1 and
lto time control unit terminal 1
lthrough 10A fuse [No. 26, located in the fuse block (J/B)]
lto interior room lamp terminal 1.
When the key is removed from ignition key cylinder, power is interrupted:
lthrough key switch terminal 2
lto time control unit terminal 18.
With the ignition key switch in the ON or START position, power is supplied:
lthrough 10A fuse [No. 5, located in the fuse block (J/B)]
lto time control unit terminal 17.
Ground is supplied:
lthrough body grounds terminals M27 and M70
lto time control unit terminal 16
When the driver side door is opened, ground is supplied:
lthrough body grounds B8 and B18
lto door switch driver side terminal 3
lfrom door switch driver side terminal 2
lto time control unit terminal 30.
When any door (except back door) is opened, ground is supplied:
lthroughcasegroundofeachdoorswitch
lto each door switch terminal 1
lto time control unit terminal 31.
When back door is opende, ground is supplied:
lthrough body ground D53
lto back door switch terminal 1
lto time control unit terminal 31.
When the driver side door is unlocked, the time control unit receives a ground signal:
lthrough body grounds terminals M27 and M70
lto door unlock sensor terminal 2
lfrom door unlock sensor terminal 5
lto time control unit terminal 28.
When a signal, or combination of signals is received by the time control unit, ground is supplied:
lthrough time control unit terminal 26
lto interior room lamp terminal 2.
With power and ground supplied, the interior room lamp illuminates.
SWITCH OPERATION
When interior room lamp switch is ON, ground is supplied:
lthrough case grounds of interior room lamp
lto interior room lamp.
INTERIOR ROOM LAMP TIMER OPERATION
When interior room lamp switch is in the “DOOR” position, the time control unit keeps the interior room lamp
illuminated for about 30 seconds when:

LT-56
INTERIOR ROOM LAMP
lunlock signal is supplied from driver's door unlock sensor while all doors are closed and key is out of igni-
tion key cylinder
lkey is removed from ignition key cylinder while all doors are closed
ldriver's door is opened and then closed while key is out of the iginition key cylinder. (However, if the
driver's door is closed with the key inserted in the ignition key cylinder after the driver's door is opened
with the key removed, the timer is operated.)
The timer is canceled when:
ldriver's door is locked,
ldriver's door is opened, or
lignition switch is turned ON.
ON-OFF CONTROL
When the driver side door, front passenger door, rear LH or RH door is opened, the interior room lamp turns
on while the interior room lamp switch is in the “DOOR” position.
