Bluetooth Telephone System Diagram
Bluetooth Control Unit
When the ignition switch is turned to ACC or ON, the Bluetooth con-
trol unit will power up. During power up, the Bluetooth control unit is
initialized and performs various self checks. Initialization may take
up to 10 seconds. During this time the Bluetooth ON indicator will
flash until initialization is complete. If a phone is present in the vehi-
cle and paired with the Bluetooth control unit, NISSAN Voice Recog-
nition will then become active and the Bluetooth ON indicator will
remain on. Bluetooth telephone functions can be turned off using the
NISSAN Voice Recognition system.
BCM
The BCM supplies power for the Bluetooth ON indicator (view with
glove box removed).
Steering Wheel Audio Control Switches
When buttons on the steering wheel audio control switch are
pushed, the resistance in steering wheel audio control switch circuit
changes depending on which button is pushed. The Bluetooth con-
trol module uses this signal to perform various functions while navi-
gating through the voice recognition system.
The following functions can be performed using the steering wheel
audio control switch:

Initiate Self Diagnosis of the Bluetooth telephone system

Start a voice recognition session

Answer and end telephone calls

Adjust the volume of calls

BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionEKS00I81
BCM (body control module) controls the operation of various electrical units installed on the vehicle.
BCM FUNCTION
BCM has a combination switch reading function for reading the operation of combination switches (light, wiper,
washer, turn signal) in addition to the function for controlling the operation of various electrical components.
Also, it functions as an interface that receives signals from the front air control, and sends signals to ECM
using CAN communication.
COMBINATION SWITCH READING FUNCTION
1. Description

BCM reads combination switch (light, wiper) status, and controls various electrical components accord-
ing 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) of the switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input ter-
minals (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 switch

BCM reads operation status of combination switch by the combination shown in the following table.
