Instrument Panel Cluster Control Module

The IPC  receives a permanent power supply from the startup battery through the Passenger Junction Box (PJB). A hardwired Light Emitting Diode (LED) security system status indicator is connected to the IPC  from the Body Control Module (BCM)/Gateway Module A (GWM).

The speedometer is driven by square wave signals derived from the wheel speed sensors which is hardwired to the Integrated Power Brake control module. The Integrated Power Brake control module transmits the signal to the BCM  /GWM  through the HS CAN  Underbody systems bus. The IPC  receives the signal from the BCM  /GWM  through the HS CAN HMI  systems bus.

The tachometer is driven by an engine speed signal from the Crankshaft Position Sensor (CKP) which is hardwired to the Powertrain Control Module (PCM). The PCM  transmits the signal from the CKP  to the BCM  /GWM  through the FlexRay. The IPC  receives the signal from the BCM  /GWM  through the HS CAN HMI  systems bus.

The Electric Steering Column Lock (ESCL) is connected directly to the IPC  on a hardwired connection. The IPC  provides a controlled ground for the ESCL.

The steering wheel switchpack inputs are sent to the IPC  through the Local Interconnect Network (LIN) connection.

The Front Infotainment Control Module (IGM/ICCM) and the HUD  are connected to the IPC  by:

• Automotive Pixel Link 2 (APIX2) connection
• HS CAN HMI  systems bus.

Other vehicle sensors are connected to the BCM  /GWM  which processes the signals from the sensors. The processed signals are delivered to the IPC  on the HS CAN HMI  systems bus. The IPC  communicates with the vehicle infotainment system on the HS CAN HMI  systems bus.

All warning sounds are generated by the infotainment system.
