TM 5-4220-231-14&P TROUBLESHOOTING - (Con't) MALFUNCTION TEST     OR    INSPECTION CORRECTIVE ACTION Step     6.     Check     pressure reading     of  the   LP   pressure gage    on   the   VTA   panel. Gage should     register     the same pressure as    LP  OUT   gage on   the    Secondary HP   Supply     side    of  the    DACC. If not,    LP OUT   supply     valve    is  faulty. Request intermediate direct    support. Check     the    supply     hoses from   the    DACC   to   the   VTA   for   kinks    or  clogs. Straighten and    clear     supply hoses. 4.     PRESSURE LOSS     AT   RECOMPRESSION CHAMBER SUPPLY HOSE. Step     1.    Check LP   OUT   gage     on   CRS. Ensure LP  Gage Isolation valve    is  open. Open     Gage Isolation     valve. If  LP  OUT    gage pressure indicates normal     operating pressure, the    problem is   downstream of  LP  OUT    gage. Ensure the    LP  SUPPLY OUT   valve    is  open. Open     LP   SUPPLY OUT    valve. If pressure is   still   not   reaching the   recompression chamber, either the    LP   SUPPLY OUT valve    is  faulty,    or   there     is   a   kink   or   blockage in  the   supply hose     from   the    CRS    to   the chamber. Straighten kinks    or   clear     blockage from    supply hose. If problem persists, request intermediate direct    support to   replace the    LP   SUPPLY OUT   valve. If  LP   OUT   gage pressure registers below    normal     operating pressure, go   to   Step    2. Step    2. Check HP   IN gage     on   CRS. If gage     indicates below    normal     operating pressure, the    problem is   upstream of  the    gage     and    the   CRS. Ensure that    DASS    has     HP   air   and    that   the   connections between the    DASS    and   the CRS     are    free   of  kinks    or   blockage. Step    3. Check SUPPLY OUTLET    valve    on   DASS    to  ensure it is  open. Open    SUPPLY OUTLET valve    on   DASS. If  HP     IN   gage on     CRS indicates normal operating pressure, the     problem is downstream of  gage;     go   to   Step    4. 3-13
