General. This paragraph provides basic screen explanations for the Pro-link 9000 with a Rockwell WABCO D Version

used types of screens are the Fault Information screens and the Component Test screens.
Fault Information Screens.
Existing Faults. Use these screens to identify existing faults. The Pro-link screen displays a written description of

that have been repaired, or faults that existed for a short time, then corrected themselves. After displaying stored
faults, Pro-link lets you erase them from memory. All stored faults are cleared at one time.
