Normal Operation and Fault Conditions
Refer to TEMPERATURE GAUGE .
NOTE:
If DTC U0100:00 is set in the IPC, other observable symptoms may be an inoperative tachometer, speedometer or odometer.
If the BCM does not receive the engine coolant temperature message from the PCM for longer than 5 seconds, the BCM and IPC set DTC U0100:00.
If the IPC does not receive the engine coolant temperature message from the BCM for longer than 5 seconds, the IPC defaults the temperature gauge to cold (C).
