A. If the resistance value is not correct :
· adjust the Artificial Feel Unit Ref. AMM 76-11-00-820-041 .
(1) If the fault continues :
· do a General Visual Inspection of the Throttle Control System Ref. AMM 76-11-00-210-040 .
· repair or replace the component as necessary.
· do the Fault Confirmation test and adjust as necessary.
(2) If the fault continues :
· install the RIGGING PIN (98DNSA20206080) in the Throttle Control Unit.
· disconnect the upper rod at the Throttle Control Lever connection Ref. AMM 76-11-41-000-041 .
