Principles of Operation: Notes

The Instrument Panel Cluster (IPC) utilizes a microprocessor to control the gauge, indicator, message center and warning chime functions. Data is sent to the IPC  over the High Speed Controller Area Network (HS-CAN), Infotainment Controller Area Network (I-CAN) bus and through hardwired circuitry from individual components. The IPC  uses each input to output an action to the gauges or indicators. In addition to the base IPC  functions, the MKX and optional Edge message centers also display audio, phone, navigation and climate control related information using the Infotainment Controller Area Network (I-CAN). The audio, phone or navigation information is controlled by the RH steering wheel switch. For additional information on the audio functions, refer to INFORMATION AND ENTERTAINMENT SYSTEMS .
