R (d) On the ECAM wheel page the forward three green triangles should R be change to amber XX. R - if there is a remaining triangle shown green, replace the R applicable proximity sensor as follows: R R - for the NLG uplock proximity sensor 12GA (Ref. AMM TASK 32-31-R 73-000-005) and (Ref. AMM TASK 32-31-73-400-005) R R - for the MLG uplocks proximity sensors 8GA and 9GA (Ref. AMM R TASK 32-31-73-000-001) and (Ref. AMM TASK 32-31-73-400-001). R

R (a) Remove the safety clip and the tag and close the circuit breaker R 2GA.
R (b) Open safety and tag the circuit breaker/s for LGCIU 1.
R NOTE : This makes sure that the LGCIU 2 has control of the L/G.
