Be sure to disconnect the ground cable first.
Check out Section 8E page 92 very informative. I think the logical place to start is at the 4-wheel speed sensors, I think it would be a good idea to visually inspect each one disconnect each connector clean and reconnect then take it for a drive so that the system has time to reset itself if that doesn't work move on to each subsequent component in the system disconnecting and reconnecting.
