A. If the test gives the maintenance message P2 DISCHARGE PRESS SENSOR(20HH):
Subtask 21-61-00-720-068-A ** ON A/C NOT FOR ALL - replace the P2 PACK DISCH PRESS SENSOR [20HH] AMM 21-61-14-000-001 and AMM 21-61-14-400-001.
- do a check of the wiring ASM 216102 from:
- the SENSOR (20HH) to the ACSC 2 (57HH) and,
- the SENSOR (20HH) to ground.
B. Do the test as given in the Para. 3.A.
