This indicates you have an issue with your ABS control unit. ABS is a system that "pumps" the brakes in rapid succession to prevent wheel lockup during an emergency start. A common cause of sliding in wet weather, etc. To do this a computer control module uses plungers to open and close the brake fluid flow to the brake in miliseconds..so while you are pressing on brake pedal hard... the system is actually applying and releasing the brake in rapid succession (miliseconds) to prevent skid, etc. When teh computer module goes bad the ABS and Parking brake light will stay illuminated. There shoudl be an ABS fuse in your vehicle (please refer to your manual) that can be removed. Remove this fuse and check it for dirt, blown, cracks, or corosion. Replace the fuse and listen with the motor off if you hear a hum noise this would indicate the motor is running continuously for the brakes and is another indicator of a bad control. With the fuse removed both lights should stay continuously lit. If the motor is running continuously this can blow the ABS motor.. your brake system will still function with the fuse removed, but test it with a slow roll (no gas hand pushed car) The ABS controller is quite pricey to replace in the vehicle and should be referred to a licensed facility such as a dealer. YES dealers are high but to have this job done properly you need to have the vehicle raised on a platform. Your local brake shop, muffler shop, shadetree wont be able to do this control repair properly.
