2. ECU Functional Description
The Instrument Panel Cluster (IPC) monitors the vehicle’s systems and functions by
considering various inputs from switches, sensors etc which are connected to it (hardwired
or through CAN). It provides the vehicle’s occupants with information regarding the status
and operating condition of these systems and functions, including.
Examples of typical functions monitored by the IPC:
Vehicle Speed
Engine Speed
Coolant Temperature
Oil Pressure
Fuel Level
Exterior Lights
Doors / Boot
Airbag (fault status)
Engine Management (fault status)
Fuel computer
The IPC communicates with other ECUs over CAN, and acts as a CAN-CAN gateway.
Through its position in the vehicle communications network, the IPC is the diagnostic
gateway to all other ECUs. The IPC acts as the Master ECU (MECU) with regard to
acquisition and transmission of Global Snapshot Data.
This specification and the referenced documents are only intended to provide information
regarding the replacement of failure IPC with new working IPC. It is not intended to provide
detailed information about the functional operation of the IPC.
