INTERIOR ROOM LAMP
 to power window main switch (door lock and unlock switch) terminal 14.
At the time that driver door are opened, BCM detects that driver door is unlocked. It determines that interior
room lamp and map lamp timer operation conditions are met, and turns interior room lamp and map lamp ON
for 30 seconds.
Key is in ignition key cylinder (key swit ch ON), or turned ignition knob switch,
Power is supplied
 through key switch and ignition knob switch terminal 4
 to BCM terminal 37,
 through key switch and ignition knob switch terminal 2
 to intelligent key unit terminal 27.
When the key is removed from key switch (key switch OFF), power supply to BCM terminal 37 is terminated.
And turned ignition knob switch, power supply to Intel ligent Key unit is terminated. BCM detects that key has
been removed, determines that interior room lamp and map lamp timer conditions are met, and turns interior
room lamp and map lamp ON for 30 seconds.
When driver door opens → closes, and key is not inserted in key s witch (or not turned ignition knob switch),
BCM terminal 62 changes between 0V (door open) → 12V (door closed). BCM determines that conditions for
interior room lamp and map lamp operation are met and turns interior room lamp ON for 30 seconds.
Timer control is canceled under the following conditions.
 Driver door is locked [when locked keyfob, power window main switch (door lock and unlock switch) or door
key cylinder switch].
 Driver door is opened (driver door switch terns ON).
 Ignition switch ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If lamps is left “ON”, it will not be turned out even when door is closed.
BCM turns off lamps automatically to save battery 30 minutes after ignition switch is turned off.
BCM controls lamps listed below:
 Ignition key hole illumination
 Front step lamp (driver side)
 Front step lamp (passenger side)
 Rear step lamp RH
 Rear step lamp LH
 Front door inside handle illumination (driver side)
 Front door inside handle illumination (passenger side)
 Rear door inside handle illumination RH
 Rear door inside handle illumination LH
 Personal lamp RH
 Personal lamp LH
 Interior room lamp (without DVD player)
 Map lamp
 Vanity mirror lamp
 Luggage room lamp
After lamps turn OFF by battery sa ver system, lamps illuminate again when
 signal from keyfob, or power window main switch (door lock and unlock switch) or key cylinder is locked or
unlocked,
 door is opened or closed,
 key is removed from ignition key cylinder or inserted in ignition key cylinder, or turned ignition knob switch.
Interior lamp battery saver control period can be changed by the function setting of CONSULT-III.

ILLUMINATION
System DescriptionINFOID:0000000001328422
Control of illumination lamps operation is dependent upon position of lighting switch (combination switch).
When lighting switch is placed in the 1ST or 2ND positi on (or if auto light system is activated), BCM (body con-
trol module) receives input signal requesting illuminati on lamps to illuminate. This input signal is communi-
cated to IPDM E/R (intelligent power distribution module engine room) through the CAN communication. The
CPU (central processing unit) located in the IPDM E/R co ntrols tail lamp relay coil. This relay, when energized,
directs power to illumination lamps, which then illuminate.
Power is supplied at all times
 through 10A fuse (No. 71, located in IPDM E/R)
 to tail lamp relay, located in IPDM E/R, and
 to CPU located in IPDM E/R.
Power is also supplied at all times
 through 50A fusible link (letter M, located in fuse, fusible link and relay box)
 to BCM terminal 55,
 through 15A fuse [No. 22 located in fuse block (J/B)]
 to BCM terminal 42,
 through 15A fuse (No. 78, located in IPDM E/R)
 to CPU located in IPDM E/R,
 through 10A fuse [No. 19 located in fuse block (J/B)]
 to unified meter and A/C amp. terminal 21 and
 to combination meter terminal 8.
With ignition switch in ON or START position, power is supplied
 to ignition relay, located in IPDM E/R, from battery direct,
 through 15A fuse [No. 1 located in fuse block (J/B)]
 to BCM terminal 38,
 through 10A fuse [No. 12, located in fuse block (J/B)]
 to unified meter and A/C amp. terminal 22 and
 to combination meter terminal 7.
With ignition switch in ACC or ON position, power is supplied
 through 10A fuse [No. 6, located in fuse block (J/B)]
 to combination meter terminal 4 and
 to BCM terminal 11.
Ground is supplied
 to BCM terminals 49 and 52
 to unified meter and A/C amp. terminals 29 and 30, and
 to combination meter terminals 5, 6, and 15
 through grounds M35, M45, and M85,
 to IPDM E/R terminals 38 and 60
 through grounds E21, E50, and E51.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With lighting switch in the 1ST or 2ND position (or if auto light system is activated), BCM receives input signal
requesting illumination lamps to illuminate. This input signal is communicated to IPDM E/R through the CAN
communication. The CPU located in the IPDM E/R controls tail lamp relay coil, which, when energized, directs
power
 through IPDM E/R terminal 22
 to glove box lamp terminal 1
 to A/T device (illumination) terminal 11
 to snow mode switch (illumination) terminal 5
 to VDC off switch (illumination) terminal 3
 to clock (illumination) terminal 3
 to hazard switch (illumination) terminal 3
 to heated seat switch (driver side) (illumination) terminal 5
 to heated seat switch (passenger side) (illumination) terminal 5
 to door mirror remote control switch (illumination) terminal 16
 to LDW switch (illumination) terminal 5
 to combination switch (spiral cable) terminal 26
 to microphone terminal 2 (with telephone system)
