BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionEKS00PA1
lBCM (Body Control Module) controls the operation of various electrical units installed on the vehicle.
BCM FUNCTION
BCM has a combination switch reading function for reading the operation of combination switches (light, wiper
washer, turn signal) in addition to the function for controlling the operation of various electrical components.
Also, it functions as an interface that receives signals from the front air control, and sends signals to ECM
using CAN communication.
COMBINATION SWITCH READING FUNCTION
Description
lBCM reads combination switch (light, wiper) status, and controls various electrical components according
to the results.
lBCM reads information of a maximum of 20 switches by combining 5output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).
Operation Description
lBCM activates transistors of output terminals (OUTPUT 1-5) periodically and allows current to flow in turn.
lIf any (1 or more) of the switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input termi-
nals (INPUT 1-5) becomes active.
lAt this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change and BCM determines that switch is ON.
PKIC1724E

BCS-6
BCM (BODY CONTROL MODULE)
Operation Mode
lCombination switch reading function has operation modes as follows:
Normal status
lWhen BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.
Sleep status
lWhen BCM is in sleep mode, BCM enters low power mode. OUTPUTS 1-5 turn ON-OFF at 22 ms inter-
vals, and receives lighting switch input only.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information through the two communication lines (CAN-L, CAN-H)
connecting the various control units in the system. Each control unit transmits/receives data, but selectively
reads required data only.

BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
lWith ignition switch ON, CAN communicates with other control units normally.
lControl by BCM is being operated properly.
lWhen ignition switch is OFF, switching to sleep mode is possible.
lEven 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
lThis status shuts down CAN communication when ignition switch is turned OFF.
lIt transmits sleep request signal to IPDM E/R and combination meter.
lTwo seconds after CAN communication of all control units stops, CAN communication switches to inac-
tive status.
3. CAN communication inactive status
lWith ignition switch OFF, CAN communication is not active.
lWith ignition switch OFF, control performed only by BCM is active.
lThree seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status
lBCM is activated with low current consumption mode.
lCAN communication is not active.
lWhen CAN communication operation is detected, it switches to CAN communication status.
lWhen a state of the following switches changes, it switches to CAN communication state:
–Key switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH) (double cab)
–Rear door switch (driver side, passenger side) No.1 (king cab)
–Rear door switch (driver side, passenger side) No.2 (king cab)
–Combination switch (passing, lighting switch 1st position, front fog lamp)
–Keyfob (lock/unlock signal)
–Door lock assembly LH (key cylinder switch)
lWhen control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
lStatus of combination switch reading function is changed.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
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 available through NISSAN Parts Department, 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.
Note: 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 TroubleshootingEIS00DI3
Refer to Table of Contents for specific component removal and installation information.
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. 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 to
repair the noise.

Door lock indicator timer
Door lock indicator timer is designed to reacts and shut down the indicator. The default timer values are 1
minute and 30 minutes.
lWhen the lock operation is activated by keyfob or auto door lock (for further details, refer toBL-92, "Auto
Re-lock Function"), then the illuminate time is set to 1 minute.
lWhen the lock operation is activated by door lock/unlock switch, then the timer is set to 30 minutes.
NOTE:
When the 30 minutes timer is active and ignition switch is turned ON, the indicator illuminate for perma-
nently, unless ignition switch is turned OFF then timer will be reset back to 30 minutes.
CAN Communication System DescriptionEIS00D7T
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitEIS00D7U
Refer toLAN-23, "CAN COMMUNICATION".
