BCM (BODY CONTROL MODULE)
Revision: 2007 April2007 M35/M45
BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
With ignition switch ON, CAN communicates with other control units normally.
Control by BCM is being operated properly.
When ignition switch is OFF, switching to sleep mode is possible.
Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status
This status shuts down CAN communication when ignition switch is turned OFF.
It transmits sleep request signal to IPDM E/R and combination meter.
Two seconds after CAN communication of all control units stops, sleep transient status is switches to
CAN communication inactive status.
3. CAN communication inactive status
With ignition switch OFF, CAN communication is not active.
With ignition switch OFF, control performed only by BCM is active.
Three seconds after CAN communication of all control units stops, CAN communication inactive status
is switches to sleep status.
4. Sleep status
BCM is activated with low power mode.
CAN communication is not active.
When CAN communication operation is detected, it switches to CAN communication status.
When a state of the following switches changes, it switches to CAN communication status.
–Key switch (ACC, ON)
–Key slot
–Intelligent Key (lock/unlock signal)
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH)
–Trunk lid opener switch
–Combination switch (passing, lighting switch 1ST position, front fog lamp)
–Key cylinder switch
When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
Status of combination switch reading function is changed.

INSULATOR (Light foam block)
80845-71L00: 30 mm (1.18 in) thick, 30×50 mm (1.18×1.97 in)
FELT CLOTHTAPE
Used to insulate where movement does not occur. Ideal for instrument panel applications.
68370-4B000: 15×25 mm (0.59×0.98 in) pad/68239-13E00: 5 mm (0.20 in) wide tape roll
The following materials, not found in the kit, can also be used to repair squeaks and rattles.
UHMW (TEFLON) TAPE
Insulates where slight movement is present. Ideal for instrument panel applications.
SILICONE GREASE
Used in place of UHMW tape that will be visible or not fit. Will only last a few months.
SILICONE SPRAY
Use when grease cannot be applied.
DUCT TAPE
Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
Generic Squeak and Rattle TroubleshootingNIS001WH
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
These incidents can usually be located by tapping or moving the components to duplicate the noise or by
pressing on the components while driving to stop the noise. Most of these incidents can be repaired by apply-
ing felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har-
ness.
CAUTION:
Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will
not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS
Pay attention to the:
1. Finisher and inner panel making a slapping noise
2. Inside handle escutcheon to door finisher
3. Wiring harnesses tapping
4. Door striker out of alignment causing a popping noise on starts and stops
Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate
many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from
the Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

System DescriptionNIS001WQ
Power is supplied at all times
through 50A fusible link (letter F , located in the fuse and fusible link box).
to BCM terminal 55,
through 10A fuse [No. 21, located in the fuse block (J/B)]
to BCM terminal 42.
When ignition switch is in ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 11.
When ignition switch is in ON or START position, power is supplied
through 15A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38.
Ground is supplied
to BCM terminal 52
through body grounds M16 and M70.
When the door is locked or unlocked with power window main switch (door lock and unlock switch), ground is
supplied
to CPU of power window main switch
through power window main switch (door lock and unlock switch) terminal 17
through grounds M16 and M70.
Then power window main switch (door lock and unlock switch) operation signal is sent.
to BCM terminal 22
from power window main switch (door lock and unlock switch) terminal 14
When the door is locked or unlocked with power window sub-switch (front passenger side) (door lock and
unlock switch), ground is supplied
to CPU of power window sub-switch
through power window sub-switch (front passenger side) (door lock and unlock switch) terminal 11
through grounds M16 and M70.
Then power window sub-switch (front passenger side) (door lock and unlock switch) operation signal is sent
to BCM terminal 22
from power window sub-switch (front passenger side) (door lock and unlock switch) terminal 16.
When the door is locked with front door key cylinder switch (driver side), ground is supplied
to CPU of power window main switch
through power window main switch (door lock and unlock switch) terminal 4
through front door key cylinder switch (driver side) terminals 6 and 4
through grounds M16 and M70.
Then front door key cylinder switch (driver side) operation signal (lock) is sent
to BCM terminal 22
from power window main switch (door lock and unlock switch) terminal 14
When the door is unlocked with front door key cylinder switch (driver side), ground is supplied
to CPU of power window main switch
through power window main switch (door lock and unlock switch) terminal 6
through front door key cylinder switch (driver side) terminals 5 and 4
through grounds M16 and M70.
Then front door key cylinder switch (driver side) operation signal (unlock) is sent
to BCM terminal 22
from power window main switch (door lock and unlock switch) terminal 14
BCM is connected to power window main switch and power window sub-switch as serial link.
