BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionNKS003XH
BCM (Body Control Module) controls the operation of various electrical units installed on the vehicle.
BCM FUNCTION
BCM has combination switch reading function for reading the operation of combination switches (light, wiper,
washer, turn signal) in addition to a function for controlling the operation of various electrical components. Also
it has an interface function allowing it to receive signals from the combination meter, and send signals to ECM
using CAN communication.
COMBINATION SWITCH READING FUNCTION
Description

BCM reads combination switch (lighting switch, wiper switch) status, and controls various electrical com-
ponent according to the result.

BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five input terminals (INPUT 1-5).
Operation Description

BCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
turn.

If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.

At 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.

Revision: 2007 April2007 M35/M45
Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status

When BCM is not in sleep status, OUTPUT terminals (1-5) send out ON signal every 10 ms.
2. Sleep status

When BCM is in sleep status, transistors of OUTPUT 1 stop the output, and BCM enters low power
mode. Mean while OUTPUT 2-5 send out ON signal every 60 ms, and accept only input from lighting
switch (except turn signal switch) system.
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-50, "
CAN System Specification Chart" .
