2. Diagnostic Information
The diagnostic information in this chapter leads you to the failing
part. Before you replace an entire assembly, determine if just the
defective part is available in the parts catalog. Some diagnostic pro-
cedures indicate the parts catalog location of the part to be checked
by including the assembly number and reference number in paren-
thesis. Some part numbers are also included. Use the error code
tables, symptom table, service checks and the diagnostic aids chap-
ter to determine the symptom and repair the failure. After you com-
plete the repair, perform the appropriate tests to verify the repair.
If an error is displayed, locate it in the following Operator Error Mes-
sage Table, or the Service Error Message Table and take the appro-
priate action.
If an error message appears while you are working on the machine,
go to the error message table and take the indicated action.
Use the Locations chapter to find connector, board, and pin informa-
tion. The sequence given in the service check is connector, board,
and pin. The board uses only a letter for an identifier. For example,
connector
CN8 = connector, A = board, -3 = the pin.
CN8A-3;
