(2) If the fault does not move with the CPC 2:
- 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).
- do the INTERFACE test of the ADR system (Ref. AMM TASK 34-13-00-
740-002). R
R (a) If the test gives a different maintenance message refer to the R Fault Symptom List.

May 01/05 CES (b) If the fault continues:
- do a check and repair the wiring of the signal DATA BUS #2 from the ADIRS 2 (1FP2) to the CPC 2 (12HL) (Ref. ASM 21-31/03) and (Ref. ASM 21-31/03).
C. If the test with the CPC 2 (12HL) gives the maintenance message NO DATA FROM ADIRS 3 (21):
- 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 2:
- 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).
- replace the CONTROLLER-CABIN PRESSURE 2 (12HL) (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 2:
- 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).
- do the INTERFACE test of the ADR system (Ref. AMM TASK 34-13-00-
740-002). R
R (a) If the test gives a different maintenance message refer to the R Fault Symptom List.
(b) If the fault continues:
- do a check and repair the wiring of the signal DATA BUS #4 from the ADIRS 3 (1FP3) to the CPC 2 (12HL) (Ref. ASM 21-31/03) and (Ref. ASM 21-31/03).
D. Do the test as given in the Para. 3.A.

3. Fault Confirmation
__________________
A. Not applicable, you cannot confirm this fault on the ground.
NOTE : In the flight phases 4 and 5 the maintenance message EIU SIGNAL
____
REPLACED shows that:
- during the take-off at least one of the throttle levers was not set to take-off power >70%.
4. Fault Isolation
_______________
A. If the CPC 1 (11HL) and/or CPC 2 (12HL) CLASS 3 FAULTS gives the maintenance messsage EIU SIGNAL REPLACED (17) caused in flight phase 7 or 8, no other maintenance action is necessary.
NOTE : The fault is caused by LDG IbouncingI or by a hard landing.
____
B. If the CPC 1 (11HL) CLASS 3 FAULTS gives the maintenance messsage EIU SIGNAL REPLACED (17) caused in flight phase other than 7 or 8 and, the take off was performed with the minimum max. climb setting (throttle levers set at 70%):
- do the operational test of the engine interface unit (Ref. AMM TASK 73-
25-34-710-040). R
R (1) If the test gives a different maintenance message refer to the Fault R Symptom List.
(2) If the fault continues:
- do a check and repair the wiring between: CPC 1 (11HL) AB/7D and EIU 1 (1KS1) AB/G1, CPC 1 (11HL) AB/8D and EIU 2 (1KS2) AB/G1 (Ref. ASM 21-31/02).
