The IPC provides dual RH and LH LCD screens to display driver information. The LH display screen contains the virtual gauge displays and message center information. The RH display screen displays multimedia information (audio, phone, navigation and climate control), as well as items such as vehicle direction, outside air temperature and time.
To alert the driver of vehicle conditions, the IPC uses:
- gauges
- informational indicators
- warning indicators
- message center indicators
- warning messages
- warning chimes
The dual screen message center IPC utilizes mostly virtual gauges. Virtual gauges are video displays that provide information in a unique format. The exception is the speedometer, which is still an analog-type gauge. Each virtual gauge is somewhat different in how it is displayed.
Informational indicators inform the driver of conditions that exist in the vehicle. Warning indicators provide information to the driver of conditions that could potentially cause personal injury or alter vehicle performance.
Message center indicators illuminate in the message center and replace the typical informational or warning indicator, using the same iconic representation. The cruise control message center indicator is in a fixed location while the others display in the order the request was received by the IPC.
Network Messaged Inputs
Module messaging has increased over time and is the standard for sending and receiving information required to operate the IPC. The majority of the inputs required to operate the IPC are received over the CAN.
Hardwired Inputs
The IPC requires hardwired inputs from components that are not on either the High Speed Controller Area Network (HS-CAN) or the Medium Speed Controller Area Network (MS-CAN). These components are required for specific IPC functions.
The hardwired inputs are provided by the following components:
- park detect switch (part of the floor shifter assembly)
- upper LH steering wheel switch (message center)
- upper RH steering wheel switch (audio control)
