Entertainment Multimedia Control Module
DESCRIPTION
| 1 - EMCM |
On vehicles equipped with the Entertainment Multimedia Control Module (EMCM) it is located on the instrument panel below the base Radio or premium Display Screen Module (DSM) if equipped, and above the Integrated Center Stack Module (ICSM).
The main menus are accessible using the EMCM for the following:
- Radio
- Media
- Phone
- Navigation
- Apps

There are various submenus dedicated to the required functions found in the main menus.
OPERATION
The EMCM control knob operates the radio functions, as well as selection between different features of the multimedia system. Both the volume and EMCM control knobs operate based on customer action; which can be twisted, shifted in all four directions, or pressed. The volume control knob connects to the EMCM through a LIN connection, where the module is the main, or master. There is also a separate circuit to control knob backlight, which is at the base of the knob. The EMCM connects to the CAN-IHS bus; and communicates separately, the customer volume input request signal to the ETM.
Below are the functions of the EMCM:
- Control knob for Entertainment Multimedia Control Module (EMCM) infotainment controls
