Brake System Indicator
WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
The brake system indicator comes on when the EBD function is lost, the parking brake is applied, and/or the brake fluid level is low.
NOTE:
If two or more wheel speed sensors fail, the brake system indicator comes on.
