A. Side Stick Identification
(1) Do the identification of the side stick installed on the aircraft AMM 27-92-41-860-801:
(a) If a new-generation side-stick unit is installed on the aircraft, refer to the trouble shooting procedure (Ref. TSM TASK 27-93-00-810-975).
(b) If the side stick installed on the aircraft is not a new-generation side-stick unit, continue this procedure.
Subtask 27-93-00-700-064-A (1) Do the identification of the side stick installed on the aircraft AMM 27-92-41-860-801:
(a) If a new-generation side-stick unit is installed on the aircraft, refer to the trouble shooting procedure (Ref. TSM TASK 27-93-00-810-975).
(b) If the side stick installed on the aircraft is not a new-generation side-stick unit, continue this procedure.
B. Test
(1) Do the operational test of the side stick assembly (activation for the BITE test) AMM 27-96-00-710-020.
(2) Do the BITE test of the EFCS (Ground Scanning) AMM 27-96-00-740-001.
4. Fault Isolation(1) Do the operational test of the side stick assembly (activation for the BITE test) AMM 27-96-00-710-020.
(2) Do the BITE test of the EFCS (Ground Scanning) AMM 27-96-00-740-001.

A. If the BITE test gives the maintenance message:
ELAC2 OR INPUT OF F/O PITCH CTL SSTU 4CE4
Subtask 27-93-00-700-065-A ELAC2 OR INPUT OF F/O PITCH CTL SSTU 4CE4
- replace the SSTU-PITCH CTL, F/O [4CE4] , AMM 27-92-41-000-002 and AMM 27-92-41-400-002.
- replace the ELAC-2 [2CE2] , AMM 27-93-34-000-001 and AMM 27-93-34-400-001.
- do a check and repair the
wiring from the ELAC 2 (2CE2) to the SSTU (4CE4) ASM 279214.
B. Do the operational test and the BITE test given in Para. 3.
