Bluetooth telephone system allows users who have a Bluetooth cellular telephone to make a wireless connec-
tion between their cellular telephone and the Bluetooth control unit. Hands-free cellular telephone calls can be
sent and received. Personal memos can be created using the Infinity Voice Recognition system. Some Blue-
tooth cellular telephones may not be recognized by the Bluetooth control unit. When a cellular telephone or
the Bluetooth control unit is replaced, the telephone must be paired with the Bluetooth control unit. Different
cellular telephones may have different pairing procedures. Refer to the cellular telephone operating manual.
Bluetooth Telephone System Diagram
Bluetooth Control Unit
When the ignition switch is turned to ACC or ON, the Bluetooth control 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. Infinity Voice Recognition
will then become active and the Bluetooth ON indicator will remain on. Bluetooth telephone functions can be
turned off using the voice recognition system.
BCM
The BCM supplies power for the Bluetooth ON indicator.
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 control module uses this
signal to perform various functions while navigating 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
• Record memos
AV Switch
Call volume can be adjusted using the AV switch.
Microphone
The microphone is located in the roof console assembly. The microphone sends a signal to the Bluetooth con-
trol unit.
Combination Meter
The combination meter supplies speed signals to the Bluetooth control unit. Vehicle speed signals are used to
determine which voice command functions will be disabled based on driving conditions.
Bluetooth ON Indicator
The Bluetooth ON indicator is located in the overhead console. The indicator will flash during power up while
the Bluetooth control unit is initializing. This process may take up to 10 seconds. After initialization, the indica-
tor will remain on to indicate that the system is ready for voice commands.

Bluetooth Control Unit Self-Diagnosis FunctionINFOID:0000000003533696
The Bluetooth control unit has two diagnostic checks. The first diagnostic check is performed automatically
every ignition cycle during control unit initialization. The second diagnostic check is performed by the techni-
cian using the steering wheel audio control switches prior to trouble diagnosis.
