BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionAKS00587

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 unified meter and A/C amp., and send signals
to ECM using CAN communication.
COMBINATION SWITCH READING FUNCTION
1. Description

BCM reads combination switch (light, wiper) status, and controls related systems such as head lamps
and wipers, according 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) 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
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 switches

BCS-4
BCM (BODY CONTROL MODULE)
Revision: 2004 November 2004 FX35/FX45

BCM reads operation status of combination switch using combinations shown in table below.
NOTE:
Headlamp has a dual system switch.
4. Sample operation: (When lighting switch 1st position 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 that light-
ing switch 1st position is ON. Then BCM sends tail lamp ON signal to IPDM E/R using CAN communi-
cation.

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.

Revision: 2004 November 2004 FX35/FX45
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON,
electrical loads are activated with time delay. But this time delay is so short that it cannot be detected by
human senses.
5. Operation mode

Combination switch reading function has operation modes shown below.
a. Normal status

When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.
b. Sleep status

When BCM is in sleep status, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low cur-
rent consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 10 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-6, "
CAN Communication Unit" .

BCS-6
BCM (BODY CONTROL MODULE)
Revision: 2004 November 2004 FX35/FX45
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

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.
–Key switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH)
–Back door opener switch
–Combination switch (passing, lighting switch 1st position, Front fog lamp)
–Key fob (lock/unlock signal)
–Key cylinder switch

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.
