Subtask 34-11-00-810-203-A ** ON A/C NOT FOR ALL
A. If the test gives the maintenance message ADM3 (19FP3)/ ADM8 (19FP8):
  • get access to the total pressure ADM (19FP3) AMM 34-11-17-000-001 (Para. 2.B.)
  • disconnect the electrical connector of the ADM (19FP3)
  • make sure that there is continuity between pins A/J, K, L, P and that there is an open circuit between pins A/M, N ASM 341303.
   (1) If the pin programming is incorrect:
  • repair the ADM-STBY TOTAL PRESSURE [19FP3]
  • connect the electrical connector of the ADM (19FP3).
   (2) If the pin programming is correct:
  • get access to the static pressure ADM (19FP8) AMM 34-11-17-000-001 (Para. 2.B.)
  • disconnect the electrical connector of the ADM (19FP8)
  • make sure that there is continuity between pins A/J, K, L, M, N, P.
     (a) If the pin programming is incorrect:
  • repair the ADM-STBY STATIC PRESSURE [19FP8]
  • connect the electrical connectors of the ADM (19FP3) and ADM (19FP8).
     (b) If the pin programming is correct:
       1 If the fault continues:
  • replace the ADM-STBY STATIC PRESSURE [19FP8] .
Subtask 34-11-00-740-133-A ** ON A/C NOT FOR ALL
B. Do the test given in Para. 3.
