INTERIOR ROOM LAMP TIMER OPERATION
Without Intelligent Key System
When room lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer
control (maximum 30 seconds) for room lamp ON/OFF.
In addition, when the interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 sec-
ond.
Power is supplied

through 10A fuse [No. 14, located in fuse block (J/B)]

to key switch and key lock solenoid terminal 2.
When the key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM termi-
nal 37.
When front door key cylinder switch LH is unlocked, ground is supplied

to BCM terminal 7

through front door key cylinder switch LH terminal 3

through front door key cylinder switch LH terminal 2

through grounds M57 and M61.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp timer operation condition is met, and turns the room lamp ON for 30 seconds.
When key is in ignition key cylinder (key switch ON),
Power is supplied

through key switch and key lock solenoid terminal 1

to BCM terminal 37.
When key is removed from key switch and key lock solenoid (key switch OFF), the power supply to BCM ter-
minal 37 is terminated. BCM detects that key has been removed, determines that interior room lamp timer
conditions are met, and turns the room lamp 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), voltage at BCM terminal 47 changes between 0V (door open) → 12V (door closed). The BCM
determines that conditions for room lamp operation are met and turns the room lamp ON for 30 seconds.
Interior room lamp timer control is canceled under the following conditions:

Front door LH is locked (locked front door key cylinder switch LH).

Front door LH is opened (front door switch LH).

Ignition switch ON.
With Intelligent Key System
When the room lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer
control (maximum 30 second) for room lamp ON/OFF.
In addition, when interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied

through 10A fuse (No. 31, located in fuse and fusible link box)

to key switch and ignition knob switch terminals 2 and 4.

ILLUMINATION
Revision: June 20062007 Versa
ILLUMINATIONPFP:27545
System DescriptionEKS00HZU
The control of the illumination lamps operation is dependent upon the position of the lighting switch. When the
lighting switch is placed in the 1ST or 2ND position, the BCM (body control module) receives input signal
requesting the illumination lamps to illuminate. This input signal is communicated to IPDM E/R (intelligent
power distribution module engine room) across CAN communication lines. CPU (central processing unit)
located in the IPDM E/R controls the tail lamp relay coil. This relay, when energized, directs power to the illu-
mination lamps, which then illuminate.
Power is supplied at all times

to ignition relay, located in IPDM E/R,

to tail lamp relay, located in IPDM E/R,

through 15A fuse (No. 52, located in IPDM E/R) and

through 20A fuse (No. 53, located in IPDM E/R)

to CPU located in IPDM E/R,

through 40A fusible link (letter g , located in fuse and fusible link box)

to BCM terminal 70, and

through 10A fuse [No. 8, located in fuse block (J/B)]

to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied

to ignition relay, located in IPDM E/R, and

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 20, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 67

through grounds M57 and M61, and

to IPDM E/R terminals 39 and 59

through grounds E15 and E24.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, BCM receives input signal requesting the illumination
lamps to illuminate. This input signal is communicated to IPDM E/R across CAN communication lines. CPU
located in the IPDM E/R controls the tail lamp relay coil, which, when energized, directs power

through 10A fuse (No. 37, located in IPDM E/R)

through IPDM E/R terminal 29

to microphone terminal 3 (with Bluetooth)

to illumination control switch terminal 1

CAUTION:
The new and former refrigerant connections use different O-ring configurations. Do not confuse O-
rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.
O-Ring Part Numbers and Specifications
WA RN ING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.

When the compressor is removed, store it in the same position as it is when mounted on the vehi-
cle. Doing so will cause oil to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.
