Pinpoint Test B : A Virtual Gauge Is Inoperative (High-Level IPC (Instrument Panel Cluster) Only): Notes
A Virtual Gauge Is Inoperative (High-Level IPC Only)
Normal Operation and Fault Conditions
See Virtual Gauges. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
Engine Temperature Gauge
- If the engine coolant temperature data or engine overheat indication request messages are missing for less than 5 seconds, the IPC defaults the temperature gauge to the last indication state, based upon the last message received.
- If the engine coolant temperature data or engine overheat indication messages are missing for 5 seconds or longer, the IPC defaults the temperature gauge to the full hot position.
Fuel Gauge
- If the IPC does not receive the fuel level input for less than 33 seconds, the IPC defaults the fuel gauge to the last indication state based on the last input received.
- If the IPC does not receive the fuel level input for longer than 33 seconds, the IPC defaults the fuel gauge to empty (E).
Engine Oil Pressure Gauge
NOTE:
If equipped with stop-start, while the vehicle is at a stop and the engine shuts off, the engine oil pressure gauge drops to 0 and the low engine oil pressure warning indicator or RTT indicator turns off.
- If the engine oil pressure warning indicator request message is missing for less than 5 seconds, the IPC defaults the engine oil pressure gauge to the last indication based upon the last message received.
- If the IPC does not receive the engine oil pressure warning indicator request message for 5 seconds or longer, the IPC defaults the engine oil pressure gauge to 0 PSI.
Transmission Temperature Gauge
- If the transmission fluid temperature message is missing for less than 5 seconds, the IPC defaults the transmission temperature gauge to the last indication based upon the last message received.
- If the IPC does not receive the transmission fluid temperature message for 5 seconds or longer, the IPC defaults the transmission temperature gauge to full cold (C).
Turbo Boost Gauge
- If the turbo boost data message is missing for less than 5 seconds, the IPC defaults the turbo boost gauge to the last indication based upon the last message received.
- If the IPC does not receive the turbo boost data message for 5 seconds or longer, the IPC defaults the turbo boost gauge to 0 PSI.
