Engine Coolant Temperature Warning

The engine coolant temperature warning telltale is turned ON by the cluster when it receives a command from the body control module (BCM). When the coolant temperature is above the specified range, the engine coolant temperature warning telltale will be illuminated.

The engine coolant temperature warning telltale is turned ON by the cluster for 2-3 seconds, when the ignition is turned to RUN, for a visual system check.
