Pinpoint Test AH: The LOW FUEL LEVEL Warning Message Is Inoperative

Normal Operation

The LOW FUEL LEVEL warning is displayed when the fuel level reaches a predetermined level of approximately one-eighth of a tank. The LOW FUEL LEVEL warning display and the fuel gauge are controlled by the Instrument Cluster (IC) based upon the Distance To Empty (DTE) calculated internally by the IC from data received from the PCM and fuel gauge. When the IC receives the data, the fuel gauge indicates low fuel and the IC displays LOW FUEL LEVEL.

This pinpoint test is intended to diagnose the following:

- Fuel gauge
- IC
