If VSGST test passes, no further action required. If VSGST test fails, then the correct fault segment must be determined. If segment 1 is not displayed, then the operator must find the correct segment before continuing. For this example, segment 1 is displayed. This is the VDT display of the repair message for segment 1. NOTE Prior to performing replace actions, check test tools for faults (connector seating, continuity, physical damage, etc.) and rerun test module. PERFORM FIRST MAINTENANCE ACTION - refer to REPLACEMENT PROCEDURE REFERENCE paragraph. Under heading “Item (Ref Des/Part No.)” find 2A2A7A6A8/ 13083050-19. On this line under the heading “Reference (Para No.)” is paragraph number 2-51. Refer to chapter 2, paragraph 2-51 and replace Pulse Generator CCA #1 2A2A7A6A8. RUN VSGST - rerun test. If VSGST test passes, then Pulse Generator CCA 2A2A7A6A8 was bad. No further action required. If VSGST test fails and its a different fault segment, then Pulse Generator CCA 2A2A7A6A8 was faulty but another fault exists. Operator must then find correct fault segment and continue troubleshooting. If VSGST test fails and its the same fault segment, then Pulse Generator CCA 2A2A7A6A8 was not faulty and troubleshooting in this leg continues. PERFORM SECOND MAINTENANCE ACTION - Refer to REPLACEMENT PROCEDURE REFERENCE paragraph and determine procedural paragraph number to replace 2A2A7A6A9/13081467-19.
