Diagnostic Overview

The Four Wheel Drive (4WD) Gauge Is Inoperative

NOTE: If DTC (Diagnostic Trouble Code) U0100:00 sets in the IPC (Instrument Panel Cluster), other observable symptoms can be an inoperative tachometer, temperature gauge or odometer.

REFER to Four Wheel Drive (4WD) Gauge .

If the AWD (All-Wheel Drive) lock torque actual message is missing for 5 seconds or less or if the IPC (Instrument Panel Cluster) receives invalid torque data for 5 seconds or less, the IPC (Instrument Panel Cluster) defaults the bar graphs in the display off.

If the IPC (Instrument Panel Cluster) does not receive the AWD (All-Wheel Drive) lock torque actual message from the PCM (Powertrain Control Module) for more than 5 seconds, the IPC (Instrument Panel Cluster) sets DTC (Diagnostic Trouble Code) U0100:00 in continuous memory and defaults the bar graphs in the display off.

Pinpoint Test

Are any DTCs (Diagnostic Trouble Codes) recorded?








2. RETRIEVE THE RECORDED DTCs (Diagnostic Trouble Codes) FROM THE PCM (Powertrain Control Module) SELF-TEST
