3. Fault Confirmation
__________________
A. Test
Do the EIS system test (Ref. AMM TASK 31-60-00-740-004).
4. Fault Isolation
_______________
A. If the test gives the maintenance message DU PFD CAPT(2WT1)/PFD CAPT POT(7WT1):
(1) If there is no CAPT PFD image:
- on the panel 301VU, make sure that the CAPT PFD potentiometer (7WT1) is in the center position
- replace the PFD-CAPT (2WT1), (Ref. AMM TASK 31-63-22-000-001) and (Ref. AMM TASK 31-63-22-400-001)
(a) If the fault continues:
- remove the panel 301VU
- on the panel 301VU, do a continuity check between the pins J and K of the connector 2101VC-A

Aug 01/05 CES 1 If there is continuity:
_
- replace the POT-PFD, CAPT (7WT1) (Ref. IPC 31680801)
- install the panel 301VU.
2 If there is no continuity:
_
- remove the DMC-1 (1WT1),
- remove the DMC-2 (1WT2)
- remove the DMC-3 (1WT3) (Ref. AMM TASK 31-63-34-000-001)
- remove the PFD-CAPT (2WT1) (Ref. AMM TASK 31-63-22-000-001)
- check the wiring between the related LRU and the first terminal block (Ref. ASM 31-68/01)
- install the DMC-1 (1WT1),
- install the DMC-2 (1WT2)
- install the DMC-3 (1WT3) (Ref. AMM TASK 31-63-34-400-001)
- install the PFD-CAPT (2WT1) (Ref. AMM TASK 31-63-22-400-001)
- install the panel 301VU
(2) If there is no variation of luminosity on CAPT PFD DU with the CAPT PFD potentiometer (7WT1) on the brightness position:
- remove the PFD-CAPT (2WT1) (Ref. AMM TASK 31-63-22-000-001)
- check the wiring between the CAPT PFD DU (2WT1) and the CAPT PFD potentiometer (7WT1) (Ref. ASM 31-68/01)
- install the CAPT PFD DU (2WT1) (Ref. AMM TASK 31-63-22-400-001)
5. Close-up
________
A. Do the test given in Para. 3.A.
Loss of the CAPT ND DU or no Variation of Luminosity on the CAPT ND DU
