Remote Control
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
Remote control on the steering wheel (standard/option) is directly connected to the Steering wheel module (SWM) via serial communication. Volume (reduce-increase) and selection of pre-programmed radio stations can be operated via remote control. During CD or USB/iPod playback, the buttons work as track selection.
The Steering wheel module (SWM) (3/254) communicates via LIN with the Central electronic module (CEM) (4/56) and on to the Infotainment control module (ICM) (16/94) via the CAN network.
The Infotainment control module (ICM) transmits the signals on to the Integrated Audio Module (IAM) (16/1) via the MOST network.
