BODY CONTROL SYSTEM
System Description
INFOID:0000000001189860
OUTLINE
• BCM (Body Control Module) controls various electrical components. It receives the information required
from CAN communication and the signals received from each switch and sensor.
• BCM has a combination switch reading function for reading the status of combination switches (light, turn
signal, wiper and washer) in addition to functions for controlling the operation of various electrical components. It also has a signal transmission function, for other systems, and the power consumption control function that reduces the power consumption with the ignition switch OFF.
• BCM is equipped with the diagnosis function that operates with CONSULT-III and allows for various settings
to be changed.

COMBINATION SWITCH READING FUNCTION

Description
• BCM reads the status of the combination switch at 10 ms interval normally.
D
E
F
JPMIA0067GB
•
-
NOTE:
BCM reads the status of the combination switch at 20 ms interval when BCM is controlled at low power consumption control mode.
BCM operates as follows and judges the status of the combination switch.
INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
It operates the transistor on OUTPUT side in the following order: OUTPUT 5 → 4 → 3 → 2 → 1.
The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of
the transistor on OUTPUT side if any (1 or more) switches are ON.
It reads this change of the voltage as the status signal of the combination switch.

Operation Example
In the following operation example, the combination of the status signals of the combination switch is replaced
as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.
Example 1: When a switch (TURN RH switch) is turned ON
BCS-11
COMBINATION SWITCH READING SYSTEM
< FUNCTION DIAGNOSIS >
• The circuit between INPUT 1 and OUTPUT 5 is formed when the TURN RH switch is turned ON.
JPMIA0122GB
• BCM detects the combination switch status signal “1E” when the signal of OUTPUT 5 is input to INPUT 1.
• BCM judges that the TURN RH switch is ON when the signal “1E” is detected.
Example 2: When some switches (turn RH switch, front wiper LO switch) are turned ON
• The circuits between INPUT 1 and OUTPUT 5 and between INPUT 1 and OUTPUT 3 are formed when the
TURN RH switch and FR WIPER LOW switch are turned ON.
JPMIA0123GB
• BCM detects the combination switch status signal “1CE” when the signals of OUTPUT 3 and OUTPUT 5 are
input to INPUT 1.
• BCM judges that the TURN RH switch and FR WIPER LOW switch are ON when the signal “1CE” is
detected.
WIPER INTERMITTENT DIAL POSITION SETTING (FRONT WIPER INTERMITTENT OPERATION)
BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2 and 3 switches.

U1000 CAN COMM CIRCUIT
Description
INFOID:0000000001189889
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, 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 Signal Chart. Refer to LAN-28, "CAN Communication Signal Chart".

Details of time display
• CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning ignition switch OFF → ON again.
• PAST: Displays when there is a malfunction that is detected in the past and stored.
• 1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases like 1
→ 2 → 3...38 → 39 after returning to the normal condition whenever ignition switch OFF → ON. The counter
remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch
OFF → ON after returning to the normal condition if the malfunction is detected again.

PRECAUTIONS

PRECAUTION
A
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
B
INFOID:0000000001189907
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIRBAG” and “SEAT BELT” of this
Service Manual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.
