 b If there is a ground signal:
_

 - do a check and repair the wiring from ECAM/ND XFR selector switch (19WT): . pin 14 to EIS DMC selector switch (18WT) pin 14 . pin 13 to DMC3 (1WT3) pin AB/8J.
 2 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).
R **ON A/C 401-499,
 A. If the EIS-DMC selector switch (18WT) is at NORM and you cannot get the ECAM DU image on the F/O ND DU:
 - do a check for a ground signal at the pin AE-4D of the DMC2 (1WT2)
 (1) If there is a ground signal:

 - replace the DMC-2 (1WT2) (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 AE-4D of the DMC2 (1WT2) to the first terminal block (Ref. ASM 31-68/01)
 B. If the EIS-DMC selector switch (18WT) is at F/O/3 and you cannot get the ECAM DU image on the F/O ND DU:
 - do a check for a ground signal at the pin AE-4D 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 AE-4D of the DMC3 (1WT3) to the first terminal block (Ref. ASM 31-68/03)

R  C. If you cannot get the image at the F/O ND DU when the EIS DMC selector 
R  switch is at NORM or at F/O/3 position: 
R  - do a check for a ground signal at the pin 5 of the ECAM PFD/ND XFR 
R  pushbutton switch (19WT) 
R  (1) If there is no ground signal : 
R  - do a check and repair the wiring from the pin 5 of the ECAM PFD/ND 
R  XFR (19WT) to the first terminal block (Ref. ASM 31-68/03) 
R  (2) If there is a ground signal: 
R  - do a check and repair the wiring from the pin 8 of the ECAM PFD/ND 
R  XFR (19WT) to the first terminal block (Ref. ASM 31-68/01) 
R  (a) If the wiring is correct: 
R  - replace the SEL SW-ECAM/ND XFR (19WT). 
R  **ON A/C ALL 
R  D. Set the ECAM/ND XFR selector switch (19WT) to F/O and make sure that the
 transfer is possible.
 5. Close-up________
 A. Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
