Reset computer??

[mcnu]

I just had a tune up and my rear wheel hub changed. I had the car on a scope and it said i had a open speed sensor on the hub. The abs and the traction lights are still on. does anyone know what i can do to get those to turn off??

you can d/c the neg battery cable for 30 minutes. that will reset the computer.

any thoughts on anything else i need to do to get these lights off of the dash?? since the hub replacement, i have had the car on the scope, and it shows nothing wrong anymore. should i try to clean the harness where it plugs into the sensor??
