English/Metric, Language And Unit Selections
The HUD English/metric, language and unit selections are controlled by messages sent from IPC. The IPC is the controlling module for the English/metric, language and unit selections and is based on the driver selections. The IPC and the HUD English/metric, language and unit selections are displayed the same.
The HUD module receives the language selection and trip unit selection from the IPC over the HS-CAN3.
