DIAGNOSTIC TEST PROGRAM (BUILT-IN TEST) (Continued)

If a fault is detected, the problem area is identified (4) and a replacement board list (5) is displayed. This list identifies

Circuit Card Assemblies (CCA's) of the SPC (6) where a possible problem exists. The list may identify from one to

twelve CCA's. The first CCA on the list is replaced with a spare CCA from stores (see 3-24). The test is resumed by

pressing RETURN on the Display Terminal keyboard. If the replaced CCA did not correct replacement list will appear on

the Display Terminal. The original CCA is then reinstalled and the next board on the list is replaced. The procedure is

repeated until all CCA's on the list have been replaced or the program continues to completion, showing that the faulty

CCA has been replaced. If all boards on the list have been replaced and the problem is not corrected, Organizational

Maintenance must be notified to perform CCA did not other Diagnostic Tests and detailed same board troubleshooting.
