Check the brake fluid level first. Fill if necessary and then see if it goes out when driven. If not, then see below.
This lamp will be illuminated when the ignition switch is placed in the ON position. The lamp may be illuminated for as long as 30 seconds as a bulb and system check. If lamp remains illuminated or comes on while operating the vehicle, a problem in the anti-lock brake system is indicated.
When lamp is illuminated, place ignition switch in OFF position, then restart engine. If lamp still remains illuminated, the antilock brake system should be serviced. The brake system will remain functional, but without the anti-lock function. After servicing the anti-lock brake system the lamp will automatically reset.
NOTE : On some models it may be necessary to operate vehicle at a speed over 18 mph to reset lamp.
This warning lamp can be activated by a low brake fluid condition, a closed parking brake switch, a bulb test switch section of the ignition switch is closed or under the control of the EBCM/EBTCM when certain ABS diagnostic trouble codes are set.
Also, there are some technical service bulletins out on ABS lights. Have you taken it to Auto Zone and had the codes pulled for free? Check that. You can email me once you have pulled to codes to let me know what they were and I can send you those tech bulletins.
