Network Message Chart - Gauges
The data on each gauge is displayed when the IPC receives messaged inputs from other modules on the CAN. The IPC communicates on the HS-CAN3. If the originating module communicates on a network other than the HS-CAN3, the messaged signals will be sent to the GWM first, then to the IPC.
| Gauge | Network Message | Originating Module | Originating CAN | Receiving Module |
|---|---|---|---|---|
| Engine oil pressure | Oil pressure warning indicator request | PCM | FD-CAN1 | IPC |
| Engine temperature | Engine coolant temperature data | PCM | FD-CAN1 | IPC |
| Engine overheat indication request | ||||
| Fuel | Fuel level display | PCM | FD-CAN1 | IPC |
| Fuel level data | IPC | HS-CAN3 | PCM | |
| Motor temperature (FHEV) | Engine coolant temperature data | PCM | FD-CAN1 | IPC |
| Engine overheat indication request | ||||
| Speedometer | Vehicle speed | PCM | FD-CAN1 | IPC |
| Tachometer | Engine rpm data | PCM | FD-CAN1 | IPC |
| Transmission temperature | Transmission fluid temperature data | PCM (gas or HEV) | FD-CAN1 | IPC |
| Turbo boost | Turbo boost data | PCM | FD-CAN1 | IPC |
