1 If the resistance values are out of the specified limits:
_ a Replace the solenoid valve of the servocontrol 34CE3 (Ref.
_ AMM TASK 27-34-51-000-005) and (Ref. AMM TASK 27-34-51-400-004).
 b Do again a check of the resistance of the solenoid valve
_ between the pin C/J and the pin C/U of the outboard elevator servocontrol (34CE3) (40 to 100 Ohms).
 - If the resistance values are out of the specified limits: . 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). . Install the SEC2 (Ref. AMM TASK 27-94-34-400-001).
- If the resistance values are in the specified limits: Install the SEC2 (Ref. AMM TASK 27-94-34-400-001).
 2 If the resistance values are in the specified limits:
_ a Repair the wiring of the SOL VLV2 signal from the
_ servocontrol (34CE3) to the SEC2 (1CE2), from the pin C/J to the pin AB/14D and from the pin C/U to the pin AE/14G (Ref. ASM 27-94/08):
 b Install the SEC2 (Ref. AMM TASK 27-94-34-400-001).
_
 (c) If the resistance values are in the specified limits: R - See Para. (3). 
R (3) At the SEC2 receptacle, do a check of the insulation between pin R AE/14G (pin AB/14D) and the ground. 
R NOTE : The resistance must be more than 100 Meghoms.
____
R (a) If the resistance is more than 100 Megohms: 
R - Replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and 
R (Ref. AMM TASK 27-94-34-400-001).
R  1_  If the fault continues: 
R  - Replace the solenoid valve (Ref. AMM TASK 27-34-51-000-005)  
R  and (Ref. AMM TASK 27-34-51-400-004). 
R 2_ If the fault continues:
R - Replace the SERVO CTL-L ELEVATOR, OUTBD B (34CE3) (Ref. AMM 
R TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001). 
R
R 3_ do a check of the wiring from the SEC2 (1CE2) COM part to theR SEC2 MON part, from the pin AB/11F to the pin AE/14E (Ref. ASM 27-94/08):
