Defective battery or something is pulling power from the battery. Check the glove box light, interior lights, trunk light, hood light, brake lights, etc.
Under the dash near the brake pedal lever.
Check your brake power booster
Brake switch.
Check the operation and alignment of the brake light switch, located at the upper end of the brake pedal under the dash area
Bring to a shop that has an ABS scanner to determine the problem
Check the fuse first then the brake light switch
If the ABS light is on, this means that there is a problem with the Anti-Lock Brake System. This is not a DIY repair. Take it to a dealer.
the brake light switch is located on the brake pedal, near the top. You will have to take off the cover right under the steering wheel to really be able to see it. Hope this answered your question
you remove plastic red/white cover with 2 screws and remove bulbs.
If the parking brake / emergency brake is on , or if the BRAKE FLUID LEVEL in your brake master cylinder in the engine compartment is LOW , and probably before you start the engine when you turn your ignition key to the RUN position just to make sure the bulb for the warning light works
