A. If the message VMO/MMO..... 235/.60 is shown on the upper ECAM DU:
- in the avionics compartment, on the relay plate 188VU, make sure that the L/G DOWN VMO/MMO SELECTION switch (22FP) is at NORM:
(1) If the switch is not at NORM:
- set the switch to NORM.
(2) If the switch is at NORM:
- do a check for a short to ground at the wiring of the L/G DOWN VMO/MMO SELECTION switch (22FP): . pin A/3E to the ADIRU1 (1FP1) pin AA/3F . pin A/3A to the ADIRU2 (1FP2) pin AA/3F . pin A/3C to the ADIRU3 (1FP3) pin AA/3F. (Ref. ASM 34-13/02).
(a) If there is a short to ground:
- repair the above wiring.
(b) If there is no short to ground:
- replace the SW-L/G DOWN VMO/MMO SELECTION (22FP).
