- do a check of the wiring of the 28VDC signal from the circuit breaker (15CC) to the rudder trim indicator (17CC)
- do a check of the wiring of the ground signal at the rudder trim indicator (17CC) pin A/F. (Ref. ASM 22-67/01).
(a) If there is no continuity:
- repair the above wirings.
(b) If there is continuity:
- replace the C/B-AUTO FLT/RUDDER/TRIM/IND (15CC).
B. If the circuit breaker 15CC is open:
- close this circuit breaker.
(1) If the circuit breaker 15CC opens again:
- replace the IND-RUDDER TRIM (17CC).
(a) If the fault continues:
- do a check for a short to ground between the circuit breaker (15CC) and the rudder trim indicator (17CC) (Ref. ASM 22-67/01).
1_ If there is a short to ground:
- repair the above wiring.
2_ If there is no short to ground:
- replace the C/B-AUTO FLT/RUDDER/TRIM/IND (15CC).
C. Do the test given in Para. 3.

CES Rudder Trim Indicator Inoperative
1. Possible Causes
_______________
- IND-RUDDER TRIM (17CC)
- wiring of the FAC 1 bus from the rudder-trim indicator (17CC) to the first terminal block
- wiring of the FAC 2 bus from the rudder-trim indicator (17CC) to the first terminal block

3. Fault Confirmation
__________________
A. Test
(1) Do the operational test of the rudder trim function (Ref. AMM TASK 22-62-00-710-001).
4. Fault Isolation
_______________
A. If the values shown on the rudder-trim indicator do not agree with the rudder movement indication on the lower ECAM DU (with the FAC 1 engaged):
- replace the IND-RUDDER TRIM (17CC).
(1) If the fault continues:
- do a check and repair the wiring of the FAC 1 bus from the rudder-trim indicator (17CC) to the first terminal block, (Ref. ASM 22-69/01).
B. If the values shown on the rudder-trim indicator do not agree with the rudder movement indication on the lower ECAM DU (with the FAC 2 engaged):
- replace the IND-RUDDER TRIM (17CC).
(1) If the fault continues:
- do a check and repair the wiring of the FAC 2 bus from the rudder-trim indicator (17CC) to the first terminal block, (Ref. ASM 22-69/01).
C. Do the test given in Para. 3.

Reset of the Rudder Trim Inoperative
1. Possible Causes
_______________
- FAC-1 (1CC1)
- ACTUATOR-RUDDER TRIM (10CC)
- FAC-2 (1CC2) R - electronic module
- wiring of the RUD TR ORDER and the RUD TR ACT VALID discretes from the FAC 1 (1CC1) to the rudder trim actuator (10CC)
