Instrument Cluster

The IPC  receives a permanent battery voltage supply through RJB. A HS CAN  powertrain bus and HS CAN  comfort bus are also connected to the IC which communicates with other control modules.

The Electric Steering Column Lock (ESCL) is connected directly to the IC and supplies the ground, supply is provided by the BCM/GWM. The steering wheel switchpack inputs are sent to the IPC  through the Local Interconnect Network (LIN) input. Other vehicle sensors are connected to the body control module/gateway module (BCM/GWM) module which processes the signals from the sensors and passes them to the IC on the HS CAN  powertrain bus. The Ambient Air Temperature (AAT) signal is received by the Powertrain Control Module (PCM) which processes the signal and passes the information to the HVAC control module (HVAC) which sends the signal to the IPC  .
