Low Oil Pressure Indicator

The IPC  uses the oil pressure warning indicator request and engine rpm data to control the low oil pressure indicator. The engine oil pressure switch is hardwired to the PCM  . The PCM  provides the oil pressure warning indicator request and the engine rpm data to the GWM  over the High Speed Controller Area Network 1 (HS1-CAN). The GWM  provides the oil pressure warning indicator request and engine rpm data to the IPC  over the High Speed Controller Area Network 3 (HS3-CAN).
