System Overview: Signals

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.

The following table summarizes the input signals to and output signals from the infotainment control module (ICM). The signal types are divided into infrared signals, MOST communication and CAN communication. The illustration below displays the same information with the Volvo component designations.
