_______________
 A. If the tests give the maintenance message CHECK PRIORITY WIRING:
 - do the tests given in Para. 3. with only the ELAC1 engaged for the operational test of the side stick priority.
 (1) If the tests give the above maintenance message again:
 - replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring of the STICK PRIORITY CAPT (DSI35) and STICK PRIORITY F/O (DSI36) signals from the ELAC1 (2CE1) COM part and MON part to the first terminal block (Ref. ASM 27-92/17).

 (2) If the tests do not give a maintenance message:
 - replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).

 1. Possible Causes
_______________
 - ELAC-1 (2CE1)

 - SEC-1 (1CE1)

 - ELAC-2 (2CE2)

 - wiring of the LOSS OF NORMAL SPLY ON 2PP (DSI53) signal

 C. Test

 (1) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
 NOTE : Open the circuit breakers FLT CTL/ELAC1/NORM/SPLY (15CE1) and
____ FLT CTL/THS ACTR/MOT1 (19CE1) before you start the ground scanning.
 4. Fault Isolation
_______________
 A. If the BITE test gives the maintenance message EMER DISCRET DISAGREE:
 - do the test given in Para. 3. (ignore the NOTE): . with the ELAC1 engaged only . with the circuit breaker FLT CTL/ELAC1/NORM/SPLY (15CE1) open . with the circuit breaker FLT CTL/THS ACTR/MOT1 (19CE1) open
 (1) If the test gives the above maintenance message again:

 - replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
 (a) If the fault continues:

 (2) If the test does not give a maintenance message:

 - do the test given in Para. 3. (ignore the NOTE): . with the SEC1 engaged only . with the circuit breaker FLT CTL/THS ACTR/MOT1 (19CE1) open . with the circuit breaker FLT CTL/SEC1/NORM/SPLY (21CE1) open
