Ok I've change out the sensor on the tranny and rear end. I now have speedo working but the park brake light and abs light continue to stay on. There are no code showing up. what's next? Could be the brake pads need changing??

 

the two times i have had both the brake light and ABS light come on at the same time with no codes.

i had to replace the front wheel hubs. first the right side then a couple of months later the left side.

 

Mine just started doing same thing. Took it to my brother-in-law's shop and he scanned it for me. It showed the left front speed sensor. Now I need to check the wiring to see if there is a broken wire or if the connecter behind the wheel well flap is corroded or something. Getting it scanned saved me alot of time to trace all the sensor wires.....now I know which one to concentrate on.
