Brake

The brake system warning telltale is turned On by the cluster when it receives a command from the BCM. The BCM sends the command when any of the following inputs occur: low brake fluid switch (indicating low brake fluid), anti lock brake system (ABS) control module (indicating a possible problem within the mechanical function of the brakes), or the park brake switch (indicating the park brake is engaged). This indicates to the operator of the vehicle that the park brake is engaged, brake fluid is low, or there is a possible problem in the basic brake system.

The brake system warning telltale is turned On by the cluster for 2-3 seconds, when the ignition is turned to RUN, for a visual system check.
