Brake Telltale
The brake telltale is turned ON by the cluster when it receives a command from the BCM or the EBTCM, indicating a possible problem within the mechanical function of the brakes. 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 mechanical portion of the antilock brake system.
During engine start-up, the brake indicator lamp will come ON for 3 seconds by the I/P cluster for a bulb check.
