Pinpoint Test B : A Virtual Gauge (Speedometer, Tachometer, Temperature Or AWD (All-Wheel Drive)), Is Inoperative: Notes

A Virtual Gauge (Speedometer, Tachometer, Temperature Or AWD), Is Inoperative

Normal Operation and Fault Conditions

AWD Gauge

If the wheel torque or vehicle speed message is missing for 5 seconds or less or if the IPC receives invalid torque data for 5 seconds or less, the IPC defaults the display fill area in front of the front wheels and behind the rear wheels to the last setting based upon that last known good message.
If the IPC does not receive the wheel torque or vehicle speed message for more than 5 seconds, the IPC sets DTC U0100:00 in continuous memory and defaults the display fill area in front of the front wheels and behind the rear wheels off.

Speedometer

If the vehicle speed message is missing or invalid for less than 5 seconds, the IPC defaults the speedometer to the last indication state, based upon the last message received.
If the vehicle speed message is missing or invalid for 5 seconds or longer, the IPC defaults the speedometer to 0 km/h (0 mph).

Tachometer

If the engine rpm data message is missing for less than 5 seconds, the IPC defaults the tachometer to the last indication state, based upon the last message received.
If the engine rpm data message is missing for 5 seconds or longer, the IPC defaults the tachometer to 0 rpm.

Temperature Gauge

If the engine coolant temperature data, engine overheat indication request, heater core temperature or engine off temperature data 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, engine overheat indication request, heater core temperature or engine off temperature data messages are missing for 5 seconds or longer, the IPC defaults the temperature gauge to the full hot position.
