A. If the test gives the maintenance message P2 CONT OR ANTI ICE VALVE:
- swap the PC 2 (27HH) and the PC 1 (7HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
(1) If the fault moves with the PC 2:
- swap back the PC 2 (27HH) and the PC 1 (7HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
- replace the CONTROLLER-PACK 2 TEMP (27HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
(2) If the fault does not move with the PC 2:
- swap back the PC 2 (27HH) and the PC 1 (7HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
- replace the VALVE-ANTI-ICE (37HH) (Ref. AMM TASK 21-61-41-000-001) and (Ref. AMM TASK 21-61-41-400-001).
(3) If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-61/02) from:
- the VALVE (37HH)A pin A and the PC 2 (27HH)AB pin 8A and,
- the VALVE (37HH)A pins B and C to ground.
