Low Oil Pressure

The message center uses the low engine oil pressure warning message as a supplement to the low oil pressure RTT indicator to inform the driver when low engine oil pressure exists. The IPC receives the engine oil pressure status from the hardwired engine oil pressure sensor and uses the engine rpm data to control the low oil pressure indicator. The engine oil pressure switch is hardwired to the IPC. The PCM provides the engine rpm data to the GWM over the HS-CAN1. The GWM provides the engine rpm data to the IPC over the HS-CAN3. The IPC requires engine rpm above 400 rpm before the message center displays the low oil pressure warning message.
