- refer to Para. Fault Isolation.
(b) If the ground scanning gives at least two maintenance messages of the list below: SEC1 OR WIRING FROM L ELEV POS MON XDCR SEC1 OR WIRING FROM R ELEV POS MON XDCR SEC1 MON OR WIRING FROM THS ACTR XDCR2 9CE SEC1 OR WIRING FROM L G ELEV MODE XDCR 34CE1 SEC1 OR WIRING FROM R Y ELEV MODE XDCR 34CE2
- do this trouble shooting procedure (Ref. TASK 27-90-00-810-818).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
SEC1 MON OR WIRING FROM THS ACTR XDCR2 9CE
(1) On the overhead panel 23VU:
- make sure that the FLT CTL/ELAC1 pushbutton switch is pushed (the FAULT and OFF legends of this pushbutton switch are off).
- release the FLT CTL/SEC1 pushbutton switch (the OFF legend of this pushbutton switche comes on).
(2) On the overhead panel 24VU:
- release the FLT CTL/ELAC2, FLT CTL/SEC2 and the FLT CTL/SEC3 pushbutton switches (the OFF legend of these pushbutton switches comes on).
(3) Pressurize the aircraft hydraulic systems (Ref. AMM TASK 29-23-00-864-001) (Ref. AMM TASK 29-24-00-864-001), (Ref. AMM TASK 29-10-00-864-003).
(4) Do the BITE test of the EFCS (Groud Scanning) (Ref. AMM TASK 27-96-00-740-001).
(a) If the ground scanning gives a maintenance message related to the ELAC1 and THS ACTR XDCR:
- replace the monitor position transducer of the THS actuator (Ref. AMM TASK 27-44-56-400-001), (Ref. AMM TASK 27-44-56-400-001)
- If the fault continues:
- replace the command position transducer of the THS actuator (Ref. AMM TASK 27-44-56-400-001), (Ref. AMM TASK 27-44-56-400-001).

Feb 01/03R CES
1_ If the fault continues:
- do a check of the wiring of the XDCR COM from the THS
actuator (9CE) to the first terminal block (Ref. ASM 27-
93/12).
2_ If the fault continues:
- do a check of the wiring of the XDCR MON from the THS
actuator (9CE) to the first terminal block (Ref. ASM 27-
93/12).
(b) If the ground scanning does not give a maintenance message related to the ELAC1 and THS ACTR XDCR:
- replace the SEC-1 (1CE1), (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(5) If the fault continues:
- do a check and repair the wiring from the ANI 2-3 XDCR MON signal of the SEC 1 (1CE1) to the first terminal block, (Ref. ASM 27-94/12).
B. Do the tests given in Para. 3.
