Phone Module (PHM)

Downloading software and replacing control module

General
New software can be downloaded to the phone module (PHM). When ordering software the vehicle software and hardware are compared to Volvo's central database. If the comparison corresponds the new software is downloaded to the control module.
If the comparison between the vehicle and the Volvo central database does not correspond, the database is updated with the vehicle configuration, and then the software and any security codes (Security access code) is downloaded.
For further information regarding downloading, see Design and Function, Downloading Software.
The phone module (PHM) is located above the glove compartment inside the dashboard.

Replacing phone module (PHM) with Volvo On Call
In addition to the software for the phone module (PHM) with Volvo On Call functionality, a unique security code is also downloaded with the software. When replacing the phone module (PHM) the security code is retrieved from the Volvo central database. A new phone module (PHM) has a generally known security code. The code is used to unlock the control module, and to program functions and to read off parameters. Unlocking is carried out automatically in the ordering version accessible in VIDA.
After software download the read off parameters are transmitted to the Volvo central database. Information about modification to the customer data for Volvo On Call are then transmitted further from the Volvo central database to the web portal that handles customer data for Volvo On Call. The information is also transmitted to the Volvo On Call Service Center via FTP (File Transfer Protocol).
The unique security code is programmed into the phone module (PHM) during software download.

The following parameters are read off and transmitted to the Volvo central database:
- GSM number for the subscription
- The security code for the unit (Security access code)
- The PUK code for the internal SIM card for Volvo On Call
- IMEI (International Mobile Equipment Identity), GSM unit serial number
- Version number on the GSM unit software
- Unit type.

Note! After replacing the phone module (PHM) with Volvo On Call functionality, the service must be activated again if the customer has an active subscription. This does not happen automatically during the order process.Phone Module (PHM) with Volvo On Call-functionality must also have the correct internal Telematic service status for it to be possible to activate the service. For more information, see Vehicle communication information, Phone Module (PHM) under Specifications, other.

Instructions and activation code for activating and deactivating Volvo On Call are available on Volvo On Call �s web site.
After activation of Volvo On Call-functionality, the phone module (PHM) will wait for information about the vehicle's position for 0.5-20 minutes.
The position is either received from multimedia module (MMM) via the MOST-net or from the GPS-antenna which is directly connected to phone module (PHM).
During this time the vehicle must be parked outside, without shielding objects, for either multimedia module (MMM) or phone module (PHM) to establish contact with GPS-satellites.
If phone module (PHM) cannot receive a position within this time frame the activation sequence will be interrupted. Volvo On Call-functionality transfers to being deactivated. After phone module (PHM) has obtained the vehicle's position the ON CALL-button shall be pressed and held in for at least two seconds to connect a voice call to Volvo On Call Service Center. This call is placed to confirm changed vehicle data and to check that Volvo On Call functions correctly.
Because of the unique security code and the internal SIM card a phone module (PHM) with Volvo On Call functionality cannot be swapped from one vehicle to another.
