Aug 01/05 CES B. Job Set-up
(1) Do the EIS start procedure (CAPT PFD and CAPT ND only) (Ref. AMM TASK 31-60-00-860-001).
(2) When the PFD and the ND images come into view on the CAPT PFD and the CAPT ND:
- push the CAPT PFD/ND XFR pushbutton switch (9WT1) on the panel 301VU.
C. Test
Make sure that the transfer is not possible.

_______________
R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299, 301-399,
A. If the transfer is not possible:
- Make sure that the circuit breaker EIS/RLY/BOX/CAPT (17WT1) is not tripped or faulty
- Make sure that the circuit breaker EIS/PFD CAPT/SWTG (22WT1) is not tripped or faulty
- Make sure that the circuit breaker EIS/ND CAPT/SWTG (23WT1) is not tripped or faulty
(1) If the fault continues:
- replace the P/BSW-PFD/ND XFR, CAPT (9WT1)
(2) If the fault continues:
- replace the RELAY BOX-CAPT PFD-ND XFR (20WT1).
(3) If the fault continues:
- do a check and repair the wiring from CAPT PFD/ND XFR pushbutton switch (9WT1) pins 1, 2 to CAPT PFD-ND transfer relay box (20WT1) pins 1D, X2.
R **ON A/C 401-499,
A. If the EIS-DMC selector switch (18WT) is at NORM and you cannot get the image on the CAPT ND DU:
- do a check for a ground signal at the pin AB-2A of the DMC1 (1WT1)
(1) If there is a ground signal:
- replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(2) If there is no ground signal :
- do a check and repair the wiring from the pin AB-2A of the DMC1 (1WT1) to the first terminal block (Ref. ASM 31-68/01)

B. If the EIS-DMC selector switch (18WT) is at CAPT/3 and you cannot get the image on the CAPT ND DU:
- do a check for a ground signal at the pin AB-2A of the DMC3 (1WT3)
(1) If there is a ground signal:
- replace the DMC-3 (1WT3) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(2) If there is no ground signal :
- do a check and repair the wiring from the pin AB-2A of the DMC3 (1WT3) to the first terminal block (Ref. ASM 31-68/01)
C. If you cannot get the image at the CAPT ND DU when the EIS DMC selector switch is at NORM or at CAPT/3 position:
- do a check for a ground signal at the pin 2 of the CAPT PFD/ND XFR pushbutton switch (9WT1)
(1) If there is no ground signal :
- do a check and repair the wiring from the pin 2 of the CAPT PFD/ND XFR (9WT1) to the first terminal block (Ref. ASM 31-68/01)
(2) If there is a ground signal:
- do a check and repair the wiring from the pin 1 of the CAPT PFD/ND XFR (9WT1) to the first terminal block (Ref. ASM 31-68/01)
(a) If the wiring is correct:
- replace the P/BSW-PFD/ND XFR, CAPT (9WT1).
**ON A/C ALL
D. Push the CAPT PFD/ND XFR pushbutton switch (9WT1) and make sure that the transfer is possible.
