PRO-LINK SCREENS

This paragraph provides basic screen explanations for the Pro-Link 9000 with a Rockwell WABCO E-version cartridge.

For complete operating instructions and test information, refer to the Pro-Link manual. The most commonly 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

the fault, including the location on the vehicle where each exists. As long as there is an active (existing) fault in the

system, the Pro-Link will not let you clear faults.

Stored Faults: Use these screens to identify faults stored in the ECU memory. Stored faults may be existing faults

that have been repaired, or faults that existed for a short time, then corrected themselves. After displaying the

stored faults, the Pro-Link lets you erase them from memory. All stored faults are cleared at one time.

Using Pro-Link:

The following illustrates a typical fault screen sequence for a 4S/4M ABS system with an existing fault.
