Volvo On Call is a system developed by Volvo which gives the owner access to various safety and service features. The system has been developed to
give the driver and passengers rapid connection to the Volvo On Call Service Center using the carphone. The staff at the service center determine the
action required depending on the circumstances. Using the data provided by the Volvo On Call system, the Service Center is able to identify the exact
position of the car so that emergency and/or breakdown services can be directed quickly to the car. The different services provided by the Service Center
can be divided into two categories, safety and service.
A Volvo On Call service can be activated in any of the following ways:
-
by the customer using the switches for Volvo On Call (3/267)
-
by the Volvo On Call Service Center
-
by the vehicle system.
The strength of the lighting in the switches for Volvo On Call is controlled via the rheostat in the light switch module (LSM) (3/111).
The phone module (PHM) (16/60) receives the rheostat signal from the central electronic module (CEM) (4/56) via the infotainment control module
(ICM) 16/1.2) on the MOST network.
When activating a Volvo On Call service, the phone module (PHM) transmits information to the infotainment control module (ICM). The infotainment
control module (ICM) transmits this data onwards to the driver information module (DIM)(5/1) so that a text message is displayed indicating that a
Volvo On Call service has been activated and its status.
Each time a Volvo On Call service is started, the relevant vehicle data is transmitted to the Volvo On Call Service Center. The vehicle data contains
information about:
-
