b Install the ELAC2 (Ref. AMM TASK 27-93-34-400-001).
_
(c) If the resistance values are in the specified limits:
- See Para.(6).
(6) At the ELAC 2 receptacle, do a check of the insulation between pin AB/14K (pin AE/14B) and the ground.
NOTE : The resistance must be more than 100 Megohms.
____
(a) If the resistance is more than 100 Megohms:
- Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
1 If the fault continues:
_ Replace the solenoid valve (Ref. AMM TASK 27-34-51-000-005) and (Ref. AMM TASK 27-34-51-400-004).
2 If the fault continues:
_ Replace the SERVO CTL-R ELEVATOR, OUTBD B (34CE4) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001).
3 do a check of the wiring from the ELAC2 (2CE2) COM part to the
_ ELAC2 COM part, from the pin AB/13K to the pin AB/13F (Ref. ASM 27-93/08):
a If the wiring is correct, see Para. 4_
_
b If the wiring is not correct:
_
- repair it
- install the ELAC2 (Ref. AMM TASK 27-93-34-400-001) 4 do a check of the wiring from the ELAC2 (2CE2) COM part to the
_ ELAC2 MON part, from the pin AB/13E to the pin AE/12D (Ref. ASM 27-93/08):
a If the wiring is correct, see Para. 5_
_
b If the wiring is not correct:
_
- repair it
- install the ELAC2 (Ref. AMM TASK 27-93-34-400-001) 5 do a check and repair the wiring from the ELAC2 (2CE2) MON
_ part pins AE/13B and AE/12C to the first terminal block (Ref. ASM 27-93/08):
6 Install the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-400-001).

(b) If the resistance is less than 100 Megohms:
- at the SERVO CTL-R ELEVATOR, OUTBD B (34CE4), 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 theSERVO CTL-R ELEVATOR, OUTBD B (34CE4) (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-R ELEVATOR, OUTBD B (34CE4) to the ELAC-2 (2CE2).
b Replace theELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001)
_ and (Ref. AMM TASK 27-93-34-400-001).
B. Do the test given in Para. 3.
