Module Network Input Messages - ACM — 2016 workshop reference 4298

those modules. Confirmation of missing messages common to multiple modules can indicate that the originating module is the source of the concern, or that the communication network may be at fault.

It is very important to understand the following:

Where the input originates All of the information necessary for a feature to operate Which module(s) receive(s) the input or command message Which module controls the output of the feature If the module that receives the input controls the output of the feature, or whether it outputs a message over the CAN to another module.

Module Network Input Messages - ACM

Broadcast Message	Originating Module	Message Purpose
Audio settings	IPC	Used to set the radio listening source (AM/ FM, Satellite, HD Radio®) from the steering wheel switch.
Audio source select	IPC	Used to set the audio system listening source (AM/ FM, CD, etc.) from the steering wheel switch through the IPC RH infotainment display.
Belt-Minder® audio mute	IPC	Used to mute speaker output so the Belt-Minder® tone can be more easily heard. This message only applies to vehicles with a MyKey® enabled and in use. The audio system is muted until the safety belt(s) are buckled.
CD request signals	GFM ( CD player)	Used to request audio source priority when the CD listening source is selected.
Day/night status	BCM	Used for day/night illumination status for the audio system.
Ignition status	BCM	Used to indicate the ignition state (OFF, ACCESSORY, RUN, and START) required for ACM operating modes and fault reporting.
Instrument panel cluster chime	IPC	Used to request a warning chime to be played through the audio system.
MyKey® volume limit status	IPC	Used to limit the maximum audio system volume when a MyKey® restricted key is in use.
Power mode	IPC	Used to disable the functionality of the ACM due to the load shedding feature.
Power up chime modules	IPC	Used to initiate the audio system as the chime source.
Vehicle configuration data	BCM	Used to verify vehicle configuration data such as the VIN and system module configuration.

Module Network Input Messages - APIM

Broadcast Message	Originating Module	Message Purpose
Airbag deployment status	RCM	Used to monitor airbag deployment status for 911 Assist™.
Audio settings	IPC	Used to set the radio listening source (AM/ FM, Satellite, HD Radio®) from the steering wheel switch through the IPC RH infotainment display.
Day/night status	BCM	Used for day/night illumination status for the FDIM.
Display language selection	IPC	Used to display information on the FDIM in the selected language.
