Section II. TROUBLESHOOTING
6.4 GENERAL,
The symptom index for EPP III lists faults associated with PDU assembly operation. Figures 5-1
through 5-10 provide a go/no-go flowchart for each malfunction. Each malfunction listed includes a
reference to the applicable figure that contains a chart to help you determine probable causes and
corrective actions to take. The symptom index cannot list all faults that may occur, or all possible
tests or inspections and corrective actions. If a malfunction is not listed or cannot be corrected by
the corrective actions listed, notify the next higher level of maintenance for assistance.
