R - On the SYSTEM REPORT/TEST/L/G page, push the line key
R adjacent to the BSCU2 indication.
R - On the BSCU CHAN 2 page, push the line key adjacent to the
R SPECIFIC DATA indication.
R - Close the circuit breakers 15CE1 and 16CE1 (the ELAC1 is
R connected).
R - Open the circuit breakers 15CE2 and 16CE2 (the ELAC2 is
R isolated).
R - On the BSCU CHAN 2/SPECIFIC DATA page, push the line key
R adjacent to SYSTEM DATA indication.
R - On the MCDU, push the next page function key twice to get
R the BSCU CHAN 2/SYSTEM DATA page 3/3.
R - On the SYSTEM DATA page 3/3 of the BSCU CHAN 2, push the
R line key adjacent to the REFRESH indication.
R - Record the value of the pedal angle (value A2).
R - Close the circuit breakers 15CE2 and 16CE2 (the ELAC2 is
R connected).
R - Open the circuit breakers 15CE1 and 16CE1 (the ELAC1 is
R isolated).
R - On the SYSTEM DATA page of the BSCU CHAN 2, push the line
R key adjacent to the REFRESH indication.
R - Record the value of the pedal angle (value B2).
R - On the MCDU, push the line key adjacent to the RETURN
R indication to get the SYSTEM REPORT/TEST/L/G page.

R - If the values A1 and/or A2 only are more than 0 deg. plus or
R minus 0.1 deg. :
R . Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001)
R and (Ref. AMM TASK 27-93-34-400-001).
R - If the values B1 and/or B2 only are more than 0 deg. plus or
R minus 0.1 deg. :
R . Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001)
R and (Ref. AMM TASK 27-93-34-400-001)
R - If the values (A1 and B1) and/or (A2 and B2) are more than 0
R deg. plus or minus 0.1 deg.:
R . Do a check of the adjustment of the pedal position
R transducer unit (25CE1, 25CE2) (Ref. AMM TASK 27-21-00-820-R 003).
R - Close the circuit breakers 15CE1, 16CE1, 15CE2 and 16CE2.
R - Do steps (b) and (c) 3_ again and make sure that the pedal
R angle value is correct for CHAN 1 and CHAN 2, if not do the
R step 6.
R 4_ If the ANGCSG value is not correct for the BSCU CHAN 1 and/orR CHAN 2, do the step 6.
R 5_ If the difference between the RVDTCOM CHAN 1 (value A) andR RVDTCOM CHAN 2 (value B) is not correct, do the step 6.
R 6_ Replace the BSCU (10GG) (Ref. AMM TASK 32-42-34-000-001) andR (Ref. AMM TASK 32-42-34-400-001).

Aug 01/05 CESR 7_ Do the steps (a) thru (c) again and make sure that all theR parameters are correct for the CHAN 1 and the CHAN 2, then do R the step 8.
R 8_ Return the aircraft to service and make a record in theR aircraft log book to monitor the NWS during the next taxi R operation and to assess the aircraft lateral deviation, if R any, using the rudder trim input. R - On the overhead panel, on the FLT CTL panel 23VU, make sure R that the ELAC1 pushbutton switch is pushed (FAULT and OFF R legends off). R - On the overhead panel, on the FLT CTL panel 24VU, make sure R that the ELAC2 pushbutton switch is pushed (FAULT and OFF R legends off). R - Refer to the Close-Up part (5.A) and do the relevant steps.
R (3) If the steering angle on the MCDU is correct, do a check of the R servovalve.
R (a) If the Fault Confirmation test was to be done only with the R taxiway procedure, put the aircraft in the necessary R configuration to let the nosewheels move freely to the left or R the right:
R 1_ If the check is to be done with the nosewheels on ground, doR these steps:
R NOTE : You will need two 1.2 m (3.93 ft.) square steel plates.
