 - If the resistance values are out of the specified limits: . 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). . 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 (34CE4) to the SEC2 (1CE2), from the pin C/J to the pin AB/15D and from the pin C/U to the pin AE/15G (Ref. ASM 27-94/08):
 b Install the SEC2 (Ref. AMM TASK 27-94-34-400-001).
