Brake Warning Lamp

The red brake warning lamp is in the instrument cluster and will illuminate to warn the driver of abnormal conditions in the brake system which may result in reduced braking ability. The lamp will illuminate when the parking brake is applied or not fully released, or if the brake fluid level switch is closed. Closed is when the brake fluid is low in the master cylinder reservoir. When the brake fluid level switch is closed, low condition, a brake warning lamp will stay illuminated until the condition has been repaired. Also some failure modes in MGH-25 system will illuminate the lamp to let the driver know de-coupled dynamic rear proportioning (DDRP) is disabled.
