A. If the test gives the maintenance message P2 FLOW SENSOR(24HB2)/PIPS(24HB1):
(a) Do a check and repair wiring ASM 216102 from:
Subtask 21-51-00-720-053-A ** ON A/C NOT FOR ALL - Replace the SENSOR-DELTA P, PACK 2 [24HB2] AMM 21-51-11-000-001 and AMM 21-51-11-400-001.
- Replace the SENSOR-PRESS, PACK 2 INLET [24HB1] AMM 21-51-13-000-001 and AMM 21-51-13-400-001.
- Replace the CONT-AIR COND SYSTEM 2 [57HH] AMM 21-61-34-000-002 and AMM 21-61-34-400-002.
(a) Do a check and repair wiring ASM 216102 from:
B. Do the test as given in the Para. 3.A.
