Brake Telltale Indicator Lamp

The BRAKE telltale indicator lamp is switched to ground by either the low brake fluid switch (indicating low brake fluid), antilock 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). When the BRAKE telltale indicator lamp is switched to ground, current from the ignition circuit flows through the indicator lamp, allowing it to come On. 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 2.9 seconds (+/-0.8 seconds), by the integrated circuit built into the l/P cluster tachometer for a bulb check.
