Re: ABS Light and Parking brake light on
Check your fuses, then check the ABS valve located beside the master cylinder and the wiring to it and finally check your speed sensor, which is located on the transmission on a 2 wheel drive and on the transfer case on a 4 wheel drive. but make sure hat your E-brake is released as it will cause these lites to come on.

Does ABS work properly? Get on dirt road and try to lock brakes (do this carefully insuring no police car tailgating,lol) Could be bad wheel speed sensor. Check codes with scan tool capable of reading ABS and trans codes.
The ABS works according to what the speed sensor tells it. The sensor may be bad or it senses a broken tooth on the tone wheel (the sensor reads these teeth on the tone wheel, found in the hub).
You will still have Brakes, but not the ABS. You can switch the sensors from the good side to the bad to see if it is in fact the sensor itself. Good luck!
sounds like your vehicle speed sensor is going out. it's the modern equivilent of a speedometer cable. it tells the computer how fast your going which the computer uses to determine shift points, abs function, and speedometer readings. they usually act up a bit before they go out. it confuses the computer. normally located in the extension housing at the rear of the transmission where the spedometer cable would be on an older vehicle
ABS and traction control really are only for panic stops and if your tires slip on wet surface's and yes each tire has a sensor on it. However if the brake light comes on this has nothing to do with the ABS or traction control lights. It's not a parking brake light. This light tells you, you have a serious brake problem.
