13.8.2.3-4 Bypassed Diagnosis Routines

To support the diagnosis of faults, diagnosis routines that are bypassed during maintenance should be run again before equipment is put back in service.

Additional Information:
When a component is serviced, it may be necessary to disable some automatic diagnosis routines. Running the routines before the equipment is put back into service ensures that they are available. It also supports the detection of any faults that may have occurred during testing. Failure to restore the diagnostic routines may increase the time required to detect future faults.
