Troubleshootingproceduresinthissectionaregroupedbycommonmalfunctionsor symptoms. A  step by   step process is   used to   identify problems, isolate components, and,    where possible, take corrective action. The   most   common and   easily    corrected causes of  malfunction are   investigated first. 3-11 General. This   section enables the   operator to   identify   which   component of  the   SDASS is  malfunctioning. In  some    cases, subcomponents (valves, regulators, etc.)   can   be   identified as   the   cause of  system malfunction. If proper positioning of   the regulator or   valves does not   correct the problem, intermediate direct    support may   be required. Prior  to  troubleshooting, ensure that   the   SDASS has    been    properly set   up,   IAW  Chapter 2. Inspect SDASS hose connections for  obvious leakage, and   inspect the   hoses for   kinks   or   crimps. NOTE If inspection reveals obvious leakage or  damage to  a  system subcomponent (other    than a  gage), request intermediate direct    support to  correct the   malfunction. In  many   cases, the   cause of  a  system malfunction is  not   immediately apparent. The   following procedures list  the steps necessary to  isolate both   the   major   SDASS assembly malfunctioning and   the   individual    faulty   subcomponent responsible for  the   malfunction. The   first,  second, and   third   sets    of  troubleshooting steps    address a  pressure loss   at  the   diver   air  supply hose    during ordinary diving   operations using   the   DASS, DACC,   and   VTA. The    fourth set of   troubleshooting steps addresses a   pressure loss at   the recompression chamber during recompression operations using   the   DASS,    CRS,    and   a  recompression chamber. The   remaining sets    of  troubleshooting steps address several simple problems and   the   step(s) necessary to  solve them. This    manual cannot list  all   malfunctions that    may   occur, nor   all  tests, inspections, and    corrective actions. If  a malfunction is  not   listed, or   if it  is   not  corrected by   listed    corrective action, notify   your   supervisor. 3-8
