The Bluetooth phone module (BPM) has the task of functioning as a wireless link between the vehicle's infotainment system and the driver's or passenger's cellphone equipped with blue tooth technology.

The following telephone functions are available via the vehicle's buttons and display when a cellphone is connected to the bluetooth phone module (BPM) via bluetooth:

• Receive incoming calls with number presentation
• End telephone calls
• Initiate telephone calls via normal number dialing
• Searching and initiating calls from the cellphone address book
• Accessing last number dialed/received/missed calls on the cellphone
• Activating voice activated function in the cellphone
• Transfer of sound between the vehicle's audio system and the cellphone can occur without interrupting the call.

The Bluetooth phone module (BPM) is located above the glove compartment inside the dashboard.

The Bluetooth phone module (BPM) cannot be combined with the Volvo On Call function.

The Bluetooth phone module (BPM) has serial optical communication with components on the MOST network where the infotainment control module (ICM) is the main control module.

The control module checks activations and input and output signals via an integrated diagnostic system. A diagnostic trouble code (DTC) is stored if the control module detects an error. In certain cases the control module replaces the faulty signal with a substitute value.

Any diagnostic trouble codes (DTCs) are stored in the control module memory. This information can be read off using the diagnostic tool via the data link connector (DLC) in the vehicle.

If the Bluetooth phone module (BPM) is not supplied with voltage there will be no communication with the MOST network and the system will shut off.

For further information, also see Signal specifications.

SIGNALS 

The table below summarizes the input signals to and output signals from the Bluetooth phone module (BPM). The signal types are divided into directly connected signals (via bluetooth) and MOST communication. The illustration below displays the same information with the Volvo component designations.
