Instantaneous Fuel Economy

Driver Information Center (DIC) Description And Operation:

Instantaneous fuel economy is calculated using IFE=Distance/Fuel:
^ Distance=The accumulated distance since last update
^ Fuel=The accumulated fuel delivered since last update

The IPC receives a class 2 message from the PCM regarding fuel usage information. The distance information is calculated by the IPC. The value of this mode is retained during ignition OFF and can be changed between English and metric by using the English/Metric DIC switch. The IFE mode cannot be reset.
