2. Diagnostic Information
Use the serial number from the indicated label to identify the
machine for reporting service related activity.
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.
