Module, Entertainment Multimedia Control (EMCM): Operation
WARNING: This page is about a different car, the 2022 RAM ProMaster 3500, 2022 RAM ProMaster 2500, and 2022 RAM ProMaster 1500. However, it is still accessible from the selected car via links, so may be relevant.
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:
