abs,vsa lights , vsa waring lights

I had my tires rotated and since that time, the VSA and ABS Lights are coming on. They don't stay on. The diagnostic code says it the VSA Module. The next morning when I back out and head forward, there's a click and the lights go out. Sometime they stay off for a while but a sharp turn like backing out of a parking space brings them back on. Is it really the Module or could it be a disconnected sensor from the tire rotation. I think the tire rotation caused it and something wasn't put back right.
