and on my old dodge w150s it meant that i had a fuse burned out. sean ive seen many posts stating this is the wheel speed sensor located on top of the rear differential costs about $25 but on my 99 it was the brake light switch located on the brake pedal braket costs about $15. in my case the lights came on at about 40 mph and cruise control didnt work. i have a 2000 dodge 1500 pickup. just recently the dashboard brake light and abs light started staying on all the time. can someone give me a clue what my problem is i removed each wheel and inspected the brake pads and hydraulic cylinders and all is in order. the brakes work fine as does the parking brake. plenty of fluid in master cylinder. is this a computer problem i do have the service manual. maybe someone could give me a page reference to solve my problem. thanks in advance. .

thanks for your replies. i did look at the fuses but didnt actually pull them and check them. which i will do. i guess ill get out my ohmmeter and start checking the brake switch and speed sensors. anyone know how to read the diagnostics codes without a scan tool brakes used to be so simple....- on fri 18 jun 2004 234620 -0700 sean prinz sprinz@msn.com wrote and on my old dodge w150s it meant that i had a fuse burned out. sean ive seen many posts stating this is the wheel speed sensor located on top of the rear differential costs about $25 but on my 99 it was the brake light switch located on the brake pedal braket costs about $15. in my case the lights came on at about 40 mph and cruise control didnt work. i have a 2000 dodge 1500 pickup. just recently the dashboard brake light and abs light started staying on all the time. can someone give me a clue what my problem is i removed each wheel and inspected the brake pads and hydraulic cylinders and all is in order. the brakes work fine as does the parking brake. plenty of fluid in master cylinder. is this a computer problem i do have the service manual. maybe someone could give me a page reference to solve my problem. thanks in advance. .
