Low Engine Coolant Indicator Malfunctions: Description

Low coolant switch closes when engine coolant level is low, and sends a discrete input to BFC. When ignition switch is in RUN position and coolant level input is low for at least 10 seconds, low engine coolant indicator will illuminate. If low coolant switch input is inactive for at least 2 seconds, low engine coolant indicator will turn off. This is a distributed function between instrument cluster and BFC.
