Pinpoint Test AP: The Low Fuel Message Center Warning Indicator Is Never On (Early Build)

Normal Operation

The low fuel message center warning indicator illuminates based upon the Distance To Empty (DTE) calculation. The DTE is calculated internally by the Instrument Panel Cluster (IPC) from data received from the PCM and the hardwired fuel level input. When the IPC determines that the DTE reaches approximately one-eighth of a tank of fuel (80 km [50 miles]) or less, the fuel gauge indicates empty and the IPC turns on the low fuel message center warning indicator.

This pinpoint test is intended to diagnose the following:

- IPC
