BCM (BODY CONTROL MODULE)
Revision: 2006 November2007 350Z
Operation Mode
The combination switch reading function has the operation modes shown below.
1. Normal mode
–When BCM is not in sleep mode, OUTPUT terminals (1 - 5) each turn ON-OFF every 10 ms.
2. Sleep mode
–When BCM is in sleep mode BCM enters low power mode. OUTPUT (1 - 5) turn ON-OFF every 60 ms,
and only input from light switch system is accepted.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information transmission through the two communication lines (CAN
L line, CAN H line) connecting the various control units in the system. Each control unit transmits/receives
data but selectively reads required data only. For details of signals that are transmitted/received by BCM via
CAN communication, refer to LAN-48, "
CAN System Specification Chart" .

CAN Communication System DescriptionNKS0009O
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. Modern
vehicles are equipped with many electronic control units and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected 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.
