Make sure everything is connected. Take some brake clean and remove any excessive greese that may have gotten on the reluctor. Also clean the pickup then unplug the connection to this unit. Put an ohm meter on both terminals

You could also reinstall your old rotors for a test but I don't think this is your problem.
Do a yahoo search for an abs scanner.
