Brake Warning Indicator

The brake warning indicator is controlled by multiple inputs and illuminates under multiple conditions. The instrument cluster is hardwired to the parking brake switch and illuminates when the parking brake is set. The instrument cluster is also hardwired to the brake fluid level switch and illuminates when the brake fluid level is low. Finally, the ABS module sends the instrument cluster a communication message, which commands the brake warning indicator on when a base brake system concern or ABS concern exists.
