3. Fault Confirmation
__________________
A. Do the operational test of the FADEC 2A and 2B on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).
4. Fault Isolation
_______________
A. Do this procedure.
NOTE : The fault is triggered by the ECU if both TLA resolver input
____ signals on channel A and B disagree. Most probable cause is an electrical wiring failure.

(1) If the test does not give the maintenance messages TLA SNSR, J3, ECU and TLA SNSR, J4, ECU:
(a) Do a check of the electrical wiring between the throttle control unit (8KS2) and the ECU (4000KS) (Ref. ASM 73-25/12).
1 if damage is found:
_
- replace or repair the above harness.
2 if nothing is found:
_ - continue the troubleshooting.
(b) Do a continuity and insulation check of this wiring.
1 if damage is found:
_
- replace or repair the above harness.
