The Four Wheel Drive (4WD) Gauge Is Inoperative
NOTE:
If DTC U0100:00 sets in the IPC, other observable symptoms can be an inoperative tachometer, temperature gauge or odometer.
REFER to Four Wheel Drive (4WD) Gauge .
If the AWD lock torque actual 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 bar graphs in the display off.
If the IPC does not receive the AWD lock torque actual message from the PCM for more than 5 seconds, the IPC sets DTC U0100:00 in continuous memory and defaults the bar graphs in the display off.
