Pinpoint Test K : The AWD Gauge Is Inoperative: Notes

Pinpoint Test K: The AWD Gauge Is Inoperative 

Diagnostic Overview 

Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Service Information for information about these practices.

Normal Operation and Fault Conditions 

REFER to AWD gauge in Instrument Panel Cluster (IPC) .

NOTE: If DTC U0100:00 sets in the IPC, other observable symptoms can be an inoperative tachometer, temperature gauge or odometer.

If the AWD lock torque actual, 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 AWD lock torque actual, wheel torque or vehicle speed message from the AWD 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.
