HANDS-FREE PHONE SYSTEM

For Hands-free phone system operation information, refer to Owner's Manual.

TEL adapter unit has Bluetooth module. It can perform wireless hands-free telephone calls using a cellu-
lar phone in vehicle compartment.

5 or less cellular phones can be registered into the TEL adapter unit.

Hands-free phone mode starts by transmitting switch signal to TEL adapter unit when pressing but-
ton.

Hands-free phone mode ends by transmitting switch signal to TEL adapter unit when pressing button.

When uttering to the microphone, microphone signal (audio signal) is transmitted from the microphone to
the TEL adapter unit and transmitted to the cellular phone with the Bluetooth
® communication.

Audio sound is muted when turning audio ON while hands-free phone system works.

Sound signal transmits to receiver's telephone through microphone unit, TEL adapter unit, and TEL
antenna when sending voice.

Sound signal outputs to front RH speakers through TEL antenna, TEL adapter unit, audio unit, and BOSE
speaker amp. when receiving voice.

BCS
Revision: 2006 July 2007 FX35/FX45
BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionNKS0033Z
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 and 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
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.

BCM (BODY CONTROL MODULE)
Revision: 2006 July 2007 FX35/FX45
Operation Table Of BCM and Combination Switches
BCM reads operation status of combination switch using combinations shown in table below.
NOTE:
Headlamp system has a dual switch.
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 lighting
switch 1ST position is ON. Then BCM sends tail lamp and clearance lamp request signal to IPDM E/R
using CAN communication.

When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5, and recog-
nizes that lighting switch 1ST position is continuously ON.
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.

BCM (BODY CONTROL MODULE)
Revision: 2006 July 2007 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.

2 seconds after CAN communication of all control units stops, sleep transient status is switched to CAN
communication inactive 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.

3 seconds after CAN communication of all control units stops, CAN communication inactive status is
switched to sleep status.
4. Sleep status

BCM is activated with low power 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.

Operation mode of combination switch reading function is changed.
