3. Fault Confirmation
__________________
A. Do the operational test of the FADEC 1A and 1B on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).

R **ON A/C 001-049, 051-099, 101-105, 151-154, 201-207,
A. If the ECAM Warning "THR LEVER FAULT" is not associated with failure messages TLA SNSR, J3, ECU and TLA SNSR, J4, ECU this is most likely indicating an internal failure of the ECU. In such a case this ECAM Warning is usually displayed with other engine related ECAM Warnings. This can be checked in the Post Flight Report (PFR) (Ref. AMM TASK 73-21-60-740-007).
(1) If the test does not give the failure messages TLA SNSR, J3, ECU and TLA SNSR, J4, ECU:
- replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).

(a) If the fault repeats and is accompagned by failure message NO ECU 1(2) ADATA:
- replace the DMU (1TV) (Ref. AMM TASK 31-36-34-000-001) and (Ref. AMM TASK 31-36-34-400-001).
1 If the fault continues:
_
- Do a continuity and insulation check of the wiring between the ECU (ARINC OUTPUT) connector J3 (pins 11 and 24) / connector J4 (pins 11 and 24) and FWC 1 and 2 (Ref. ASM 73-25/10).
a if damage is found:
_
- replace or repair wiring as required.
b if nothing is found:
_
- repeat the fault isolation procedure.
(2) If the test gives the failure messages TLA SNSR, J3, ECU and/or TLA SNSR, J4, ECU:
- Do the related troubleshooting procedure.
