A. If one or both of the reports, LAST LEG REPORT, PREVIOUS LEG REPORT and/or the test gives the maintenance message,
- PRESS CONTROLLER 1 (51):
- swap the CPC 1 (11HL) and the CPC 2 (12HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
(1) If the fault moves with the CPC 1:
- swap back the CPC 1 (11HL) and the CPC 2 (12HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
(a) Replace the CONTROLLER-CABIN PRESSURE 1 (11HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).

(2) If the fault does not move with the CPC 1:
- swap back the CPC 1 (11HL) and the CPC 2 (12HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
(a) Replace the VALVE-OUTFLOW (10HL), ELECTRONIC MODULE 1 (Ref. AMM TASK 21-31-51-000-002) and (Ref. AMM TASK 21-31-51-400-002).
NOTE : The electronic module 1 is connected to the electrical
____
connector 10HL-A.
(3) If the fault continues:
(a) do a check and repair the wiring from the:
- CPC 1 controller (11HL-AA) pins 7A, 8A, 9A and 10A to the OFV connector (10HL-A) pins R, P, N and M (Ref. ASM 21-31/02).
(b) Do a check of the earthing resistance at the return ground connections (Ref. AMM 21310076000100) on:
- the CPC 1 connector 11HL-AC, pin 2 and on,
- the electronic module 1 connector 10HL-A, pin J.
NOTE : The resistance must be smaller than 20 m.ohms.
____
B. Do the test as given in the Para. 3.A.
