Low Brake Fluid Warning

The brake fluid level switch is grounded when the brake fluid falls below a specified level. The brake fluid level switch provides the brake fluid level information to the instrument cluster. When the instrument cluster detects that the brake fluid level switch is closed, the instrument cluster directs the driver information center (DIC) to display the LOW BRAKE FLUID warning. The instrument cluster transmits the data to the DIC through the universal asynchronous receiving/transmitting (UART) B serial data line.
