Low Fuel Lamp/Indicator: Description and Operation

When the Body Control Module (BCM) detects a low fuel condition based on the fuel level sensor input it transmits a message across the CCD Bus to the instrument cluster to illuminate the low fuel lamp.

When the gauge indicator shows approximately 1/8 tank of fuel remaining, the LED will light, alerting the driver to a low fuel condition.

When the gauge indicator shows engine temperature to be 240-260°F, the LED will light, alerting the driver to an overheating condition.
