 A. Test Do the operational test of the rudder artificial-feel loads (Ref. AMM TASK 27-23-00-710-001).
 4. Fault Isolation
_______________
 A. If during the test, after activation of the rudder artificial-feel solenoid, the force to move the rudder pedals does not increase.
 (1) Replace the SOLENOID-RUDDER ARTF FEEL (16CA) (Ref. AMM TASK 27-23-17-000-001) and (Ref. AMM TASK 27-23-17-400-001).

 (2) If the fault continues:

 - replace the artificial feel and trim unit (Ref. AMM TASK 27-23-41-000-001) (Ref. AMM TASK 27-23-41-400-001).
 B. Do the test given in para. 3.

 B. If there are fluctuations of the pointer of the RUD indicator on the F/CTL page:
 (1) Open the circuit breakers 3WV, 5WV, 7WV and 44WV.

 (a) If the fluctuations of the pointer continue:

 - see para.(2).

 (b) If the fluctuations of the pointer stop:

 - replace the SDAC-1 (1WV1) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).

 - do a check of the wiring from the SDAC 1 to the first terminal block (Ref. ASM 31-54/08) (RUD POS XDCR unit side).

 - do a check of the wiring from the SDAC 1 to the first terminal block (Ref. ASM 31-54/04) (DMC side).

 (2) Close the circuit breakers 3WV, 5WV, 7WV and 44WV.

 (3) Open the circuit breakers 2WV, 6WV, 8WV and 44WV.

 (a) If the fluctuations of the pointer continue:

 - see para.(5).

 (b) If the fluctuations of the pointer stop:

 - replace the SDAC-2 (1WV2) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
