The IPC uses the oil pressure warning indicator request network message to control the oil pressure gauge. The engine oil pressure switch is hardwired to the PCM. The PCM sends the oil pressure warning indicator request message to the GWM over the HS-CAN1. The GWM sends the oil pressure warning indicator request message to the IPC over the HS-CAN3.
