Instrument Panel Cluster - Conventional Display

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 Control Module (GWM).

The speedometer is driven by square wave signals derived from the wheel speed sensors and the ABS  . The signal is received on the HS CAN  chassis systems bus.

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

The Electric Steering Column Lock Control Module (VIM) is connected directly to the IPC  on a hardwired connection. The IPC  provides a controlled ground for the VIM  . The steering wheel switch inputs are sent to the IPC  through the Local Interconnect Network (LIN) connection.

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  chassis systems bus and the HS CAN  comfort systems bus. The IPC  communicates with the vehicle infotainment system on the HS CAN  comfort systems bus.
