1.   An AWD system is a system of wheel sensors and a control module.

2.   An electronic control module determines whether the key is acceptable and will prevent ignition if the key is not a match.

3.   Because the interim control module also uses a different docking mechanism than Zvezda, astronauts would have to reconfigure the dock in the Zarya module now in orbit.

4.   A GM subsidiary, GM Hughes Electronics, builds the computer control module for the Impact and also sells a system in wide use by other electric car teams.

5.   After a shuttle rendezvous with the control module, spacewalking astronauts will link the first two components.

6.   But once the vehicle is moving, the powertrain control module activates the displacement on demand system.

7.   Endeavor carried a docking port to connect with the control module, the first two major components of an international Earth orbiting space station.

8.   Hawes said a major decision in the process was how to use the American-made backup unit for the Service Module, termed the interim control module.

9.   If Zvezda is successfully launched on time, the interim control module will still become part of the station, but in a slightly different role.

10.   NASA Administrator Daniel Goldin said the United States would complete and launch a new control module for the station that could replace the long-delayed Russian service module.
