_______________
A. If the BITE test gives the maintenance message: SEC2 OR OUTPUT TO THS ACTR SERVO MOT3 9CE
- replace the SEC-2 (1CE2), (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(1) If the fault continues:
- replace the motor 3 assembly of the pitch trim actuator, (Ref. AMM TASK 27-44-57-000-003) and (Ref. AMM TASK 27-44-57-400-003).
(2) If the fault continues:
- do a check and repair the wiring of the command signal from the THS actuator (9CE) to the SEC 2 (1CE2), (Ref. ASM 27-94/13).
(3) If the fault continues:
- replace the pitch trim actuator, (Ref. AMM TASK 27-44-57-000-001) and (Ref. AMM TASK 27-44-57-400-001).

A. Test
(1) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
NOTE : If there is an EFCS message which is not related to an ADR
____ FAULT (NAV ADRX FAULT or ADR-STATUS), do not remove the ADIRU; refer to these procedures:
(a) If flight in turbulence:
- (Ref. TASK 34-11-00-810-870).
(b) If the fault continues:
- (Ref. TASK 34-13-00-810-998)
- (Ref. TASK 34-11-00-810-861).

4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message: SEC1 OR BUS3 FROM ADR1
- read the Post Flight Report (PFR) for the maintenance messages ADR3 with AFS in IDENT or ADIRU 1/2/3 DISAGREE with the AFS source.
(1) If one of these maintenance messages comes into view on the PFR:
- do this trouble shooting procedure (Ref. TASK 34-13-81-810-825).
(2) If these maintenance messages do not come into view on the PFR:
- replace the SEC-1 (1CE1) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(a) If the fault continues:
- do a check and repair the wiring of the DGI-06 signal from the SEC 1 (1CE1) to the first terminal block COM and MON parts (Ref. ASM 27-92/53).
B. Do the test given in Para. 3.
