DEFINITIONS AND DESCRIPTIONS OF TROUBLESHOOTING PROCEDURES
Troubleshooting tasks always have a beginning and an end. You will use task steps, test procedures, indexes,
maintenance tasks, and other technical manuals to troubleshoot. Troubleshooting uses the following terms
that are not used in other kinds of tasks:
The part that is not operating correctly and is causing problem.
The problem reported to direct and general support maintenance.
VERIFY NO FAULTS FOUND:
After you have completed the corrective action, you must verify
that no faults exist. If the fault condition still exists, then fault is not fixed or there is another fault. If
this happens, start at beginning of troubleshooting procedure until you find and correct all faults.
Always operate system and/or carrier to make sure that you have corrected the reported problem. If
troubleshooting does not identify a faulty part, the earner is defective beyond the level of direct and
general support maintenance.
