Hands-Free Phone System: System Description
Refer to the Owner's Manual for Bluetooth telephone system operating instructions.
Note. Cellular telephones must have their wireless connection set up (paired) before using the Bluetooth telephone system.
Bluetooth telephone system allows users who have a Bluetooth equipped cellular telephone to make a wireless connection between their cellular telephone and the Bluetooth control unit. Hands-free cellular telephone calls can be sent and received. Some Bluetooth 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.
Diagnosis Description
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 technician using the steering wheel audio control switches prior to trouble diagnosis.
The audio unit sends audio signals to the front door speakers using the audio signal circuits.
The audio unit sends audio signals to the tweeters using the audio signal circuits.
The audio unit sends audio signals to the rear door speakers using the audio signal circuits.
When one of the steering wheel audio control switches is pushed, the resistance in the steering wheel audio control switch circuit changes depending on which button is pushed.
Communication signals are exchanged between the audio unit and satellite radio tuner using the communication circuits.
Left and right channel audio signals are supplied from the satellite radio tuner to the audio unit through the sound signal circuits.
Voice signals are transmitted from the microphone to the Bluetooth control unit using the microphone signal circuits.
