Network Message Chart
WARNING: This page is about a different variant/trim than selected.
MODULE NETWORK INPUT MESSAGES - ACCESSORY PROTOCOL INTERFACE MODULE (APIM)
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| Climate control status | Heating, Ventilation, and Air Conditioning (HVAC) | This message contains the Heating, Ventilation, and Air Conditioning (HVAC) status. |
MODULE NETWORK INPUT MESSAGES - POWERTRAIN CONTROL MODULE (PCM)
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| Air Conditioning (A/C) request | Heating, Ventilation, and Air Conditioning (HVAC) module | This message requests the A/C compressor to be engaged. |
| Battery air flow request | Battery Energy Control Module (BECM) | This message requests the electric A/C compressor to be engaged to cool battery packs. |
| Evaporator temperature | Body Control Module (BCM) | This message contains the evaporator temperature. The Powertrain Control Module (PCM) uses the evaporator temperature to cycle the electric A/C compressor. |
| Sun Load Sensor Data | Heating, Ventilation, and Air Conditioning (HVAC) module | This message contains the sunload sensor information. The Powertrain Control Module (PCM) uses the sunload sensor information to increase the A/C compressor clutch cycle time. |
MODULE NETWORK INPUT MESSAGES - HEATING, VENTILATION, AND AIR CONDITIONING (HVAC) MODULE
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| Air Conditioning (A/C) compressor temperature status | Air Conditioning Control Module (ACCM) | This message contains the A/C compressor temperature status. |
| Ambient air temperature | Powertrain Control Module (PCM) | This message contains raw value from the ambient air temperature sensor. |
| Climate control requests | Accessory Protocol Interface Module (APIM) | This message contains both the climate control system voice commands as well as all climate control system touch screen inputs. |
| Evaporator temperature | Body Control Module (BCM) | This message contains the evaporator temperature. |
MODULE NETWORK INPUT MESSAGES - AIR CONDITIONING CONTROL MODULE (ACCM)
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| Air Conditioning (A/C) compressor enable request | Powertrain Control Module (PCM) | This message requests the A/C compressor to be engaged. |
