(b) If the resistance is less than 100 Megohms:
- at the SERVO CTL-L ELEVATOR, OUTBD B (34CE3), do a check of the insulation of the solenoid valve between pin C/K (pin C/L) and the ground.

1_ If the resistance is less than 100 Megohms:
- replace the solenoid valve (Ref. AMM TASK 27-34-51-000-005)
and (Ref. AMM TASK 27-34-51-400-004).
a Do again a check of the insulation of the solenoid valve
_ between pin C/K (pin C/L) and the ground. If the resistance is less than 100 Megohms: . Replace the SERVO CTL-L ELEVATOR, OUTBD B (34CE3) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001). . Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
2 If the resistance is more than 100 Megohms:
_
a Repair the wiring of the solenoid valve signal from the
_ SERVO CTL-L ELEVATOR, OUTBD B (34CE3) to the ELAC-2 (2CE2)
b Replace the ELAC-2 (2CE2).
_
B. Do the test given in Para. 3.

__________________
A. Test
(1) Do the operational test of the side stick assembly (activation for the BITE test) (Ref. AMM TASK 27-96-00-710-020).
(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
(a) If the ground scanning gives the maintenance message: ELAC2 OR WIRING FROM L G ELEV POS XDCR 34CE1
- refer to Para. Fault Isolation.
(b) If the ground scanning gives at least two maintenance messages of the two lists below: First list:
- ELAC2 COM OR INPUT OF THS ACTR XDCR1 9CE
- ELAC2 OR WIRING FROM L G ELEV POS XDCR 34CE1
- ELAC2 OR WIRING FROM R Y ELEV POS XDCR 34CE2 Second list:
- ELAC2 MON OR INPUT OF THS ACTR XDCR1 9CE
- ELAC2 OR WIRING FROM L ELEV POS MON XDCR
