Revision: June 20062007 Versa
BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionEKS00I81
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 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
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-4
BCM (BODY CONTROL MODULE)
Revision: June 20062007 Versa
NOTE:
Headlamp has a dual system switch.
4. Example operation: (When lighting switch 1st position is turned ON)

When lighting switch 1st position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.

When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges lighting
switch 1st position is ON. Then BCM sends tail lamp ON signal to IPDM E/R using CAN communica-
tion.

When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5 and rec-
ognizes that lighting switch 1st position is continuously ON.
SKIB7614E

BCS-6
BCM (BODY CONTROL MODULE)
Revision: June 20062007 Versa

When BCM is in sleep mode, transistors of OUTPUT 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 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, 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 control units stops, CAN communication switches to
inactive status.
4. Sleep status

Revision: June 20062007 Versa

BCM is activated with low current consumption 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 state:
–Ignition switch
–Key switch (without Intelligent Key)
–Key switch and ignition knob switch (with Intelligent Key)
–Hazard switch
–Door lock/unlock switch
–Front door switch (LH, RH)
–Rear door switch (LH, RH)
–Back door lock assembly
–Combination switch (passing, lighting switch 1st position, front fog lamp)
–Keyfob (lock/unlock signal)
–Front door key cylinder switch LH

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.
