- If the resistance values are in the specified limits: Install the ELAC1 (Ref. AMM TASK 27-93-34-400-001).

 2 If the resistance values are in the specified limits:
_
 a Repair the wiring of the SOL VLV1 signal from the
_ servocontrol (34CE2) to the ELAC1 (2CE1), from the pin C/K to the pin AB/14K and from the pin C/L to the pin AE/14B (Ref. ASM 27-93/07):
 b Install the ELAC1 (Ref. AMM TASK 27-93-34-400-001).
_
 (c) If the resistance values are in the specified limits:
 - See Para. (3).
 (3) At the ELAC 1 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-1 (2CE1) (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, INBD Y (34CE2) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001).

_
 b If the wiring is not correct:
_
 - repair it

 - install the ELAC1 (Ref. AMM TASK 27-93-34-400-001)

 5 do a check and repair the wiring from the ELAC1 (2CE1) MON
_ part pins AE/13B and AE/12C to the first terminal block (Ref. ASM 27-93/07):
 6 Install the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-400-001).
_
 (b) If the resistance is less than 100 Megohms:
 - at the SERVO CTL-R ELEVATOR, INBD Y (34CE2), 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-R ELEVATOR, INBD Y (34CE2) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001). . Replace the ELAC-1 (2CE1) (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, INBD Y (34CE2) to the ELAC-1 (2CE1).
 b Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001)
_ and (Ref. AMM TASK 27-93-34-400-001).
