BCM (BODY CONTROL MODULE)
System Description INFOID:0000000004306833
BCM (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 c ontrolling the operation of various electrical components.
Also, it functions as an interface that receives signal s from the front air control, and sends signals to ECM
using CAN communication.
COMBINATION SWITCH READING FUNCTION 1. Description • BCM reads combination switch (light, wiper) status , and controls various electrical components accord-
ing to the results.
• BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five input terminals (INPUT 1-5).
2. Operation description • BCM activates transistors of output terminals (OUTPUT 1-5) periodically and allows current to flow in
turn.
• If any (1 or more) of the switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input ter-
minals (INPUT 1-5) becomes active.
• At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When
voltage of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects
voltage change and BCM determines that switch is ON.
3. BCM - Operation table of combination switch • BCM reads operation status of combination switch by the combination shown in the following table.

BCS
N
O P
Normal status
• When BCM is not in sleep status, OUTPUT te rminals (1-5) each turn ON-OFF every 10ms.
Sleep status
• When BCM is in sleep mode, transistors of OUTP UT 1 and 5 stop the output, and BCM enters low-cur-
rent-consumption mode. OUTPUTS (2, 3, and 4) turn ON-OFF at 60ms intervals, 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 stat us 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 co mmunication 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, CAN communication switches to inac-
tive 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 cont rol units stops, CAN communication switches to
inactive status.
4. Sleep status • BCM is activated with low current consumption mode.
• CAN communication is not active.

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Work Flow INFOID:0000000004304977
CUSTOMER INTERVIEW Interview the customer if possible, to determine the c onditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interv iew to document the facts and conditions when the noise occurs and any
customer's comments; refer to BL-11, " Diagnostic Worksheet " . This information is necessary to duplicate the
conditions that exist when the noise occurs.
• The customer may not be able to provide a detailed descr iption or the location of the noise. Attempt to obtain
all the facts and conditions that exist when the noise occurs (or does not occur).
• If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer is
concerned about. This can be accomplished by test driving the vehicle with the customer.
• After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
• Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces
= higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
• Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.
• Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.
• Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/someti mes repeating/often brought on by driver action.
• Tick—(Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loose components/can be caused by driver
action or road conditions.
• Thump—(Heavy, muffled knock noise) Thump characteristics include softer k nock/dead sound often brought on by activity.
• Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
• Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge as acceptable may be very irritating to the customer.
• Weather conditions, especially humidity and temperature, may have a great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.

Generic Squeak and Rattle Troubleshooting " .
REPAIR THE CAUSE
• If the cause is a loose component, tighten the component securely.
• If the cause is insufficient clearance between components:
- separate components by repositioning or loos ening and retightening the component, if possible.
- insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane
tape. A NISSAN Squeak and Rattle Kit (J-43980) is av ailable through your authorized NISSAN Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
