Pinpoint Test B : A Virtual Gauge Is Inoperative (Diesel Exhaust Fluid Level, Engine Temperature, Fuel, Oil Pressure, Transmission Temperature Or Turbo Boost): Notes

Normal Operation and Fault Conditions 

See Virtual Gauges. Refer to: Instrument Panel Cluster (IPC) - System Operation and Component Description .

Diesel Exhaust Fluid Level 

• If the diesel exhaust fluid level indicator message is missing for less than 5 seconds, the IPC defaults the diesel exhaust fluid level gauge to the last indication state, based upon the last message received.
• If the diesel exhaust fluid level indicator message is missing for 5 seconds or longer, the IPC defaults the diesel exhaust fluid level gauge to the empty (E) position.

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).

Oil Pressure Gauge 

• If the oil pressure warning indicator request message is missing for less than 5 seconds, the IPC defaults the oil pressure gauge to the last indication based upon that last message received.
• If the IPC does not receive the oil pressure warning indicator request message for 5 seconds or longer, the IPC defaults the 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 that 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.
