Infotainment Control Module (ICM) [2012-2016]: Function
CONTROLLING FUNCTIONS
Infotainment control module (ICM) (3/281) is controlled with the keypad on Climate control module (CCM) (4/6), remote control infotainment or via Steering wheel switch right (SWSR). The signals from the keypad on Climate control module (CCM) are sent via the CAN. The signals from Steering wheel switch right are sent via LIN. The signals from remote control infotainment are sent via IR.
The functions controlled with the buttons are:
- AM
- FM
- CD
- AUX
- Eject
- Digital radio
- USB (option/accessory)
- iPod (option/accessory)
- Navigation (option)
- Phone
- DVD video
- Television (option)
- Rear seat entertainment (only XC60) (option)
For more information about the keypad on the climate control module (CCM), see Design and Function - Climate Control Module (CCM).
CONTROLLING THE FUNCTIONS USING THE STEERING WHEEL BUTTONS
(S60 (11-), V60, XC60, V70 (08-), XC70 (08-), S80 (07-))
(V40 (13-))
The steering wheel buttons connected to the steering wheel module (SWM) (3/130) can be used to control:
- Volume control and CD track / radio selection
- Menu selection for traffic information
- volume control during hands free carphone calls and menu selection for the phone module (PHM) (16/60)
- volume control for Television Module (TVM) (16/36) (option)
- volume control for Rear seat entertainment module (RSE) (16/109) (only XC60) (option)
The signals from the steering wheel buttons are transmitted to the steering wheel module (SWM) (3/130) with LIN communication. The steering wheel module (SWM) transmits the signals on to the Infotainment Control Module (ICM) (3/281) using LIN communication. The infotainment control module (ICM) in turn transmits the signals on to the affected control module on the MOST network.
For more information, see Design and Function - Steering wheel module (SWM).
FUNCTIONS CONTROLLED BY THE INFOTAINMENT CONTROL MODULE (ICM)
For information about the functions controlled by the infotainment control module (ICM) but carried out by other control modules on the MOST network, see Design and Function for the relevant control module and for the MOST network.
INFOTAINMENT THEFT PROTECTION (ITP)
(S60 (11-), V60, XC60, V70 (08-), XC70 (08-), S80 (07-))
(V40 (13-))
The Infotainment Theft Protection (ITP) function is designed to prevent non-approved control modules from being installed in the infotainment system. This is to prevent the theft of units.
The function is controlled by the infotainment control module (ICM). The infotainment control module (ICM) (3/281) checks the serial number on all control modules in the MOST network and compares these with a list stored in the central electronic module (CEM). The list is transmitted to the infotainment control module (ICM) via CAN. The infotainment control module (ICM) retrieves data about the serial number of the control modules via the MOST network. The infotainment control module (ICM) compares the information with the stored serial numbers.
If a control module is not in the stored list, it is disconnected from the MOST network and the functionality of this control module is blocked. This means that control modules in the MOST network cannot be moved from one vehicle to another.
If a control module is not included in the stored list or if a control module in the stored list responds incorrectly, then a diagnostic trouble code (DTC) is stored in the infotainment control module (ICM).
