3. Fault Confirmation__________________
Removal of the ECU (Channel A) Harness (4211KS)
Removal of the ECU (Channel B) Harness (4212KS)
Installation of the ECU (Channel A) Harness (4211KS)
Installation of the ECU (Channel B) Harness (4212KS)
Visual Inspection of the Wiring Harnesses
Removal of the Electronic Control Unit (ECU)(4000KS)
Installation of the Electronic Control Unit
(ECU)(4000KS)
Operational Test of the FADEC on the Ground (with
Engine non Motoring)
Removal of the Throttle Control Unit (8KS1, 8KS2)
Installation of the Throttle Control Unit (8KS1,
8KS2)
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).
4. Fault Isolation
_______________
R A. Do this procedure.
R NOTE : The fault is triggered by the ECU if both TLA resolver input
____ R signals on channel A and B are invalid or out of range. Most R probable cause is an electrical wiring failure or an ECU internal R failure.

R (1) If the test does not give the maintenance messages TLA SNSR, J3, ECU
R and/or TLA SNSR, J4, ECU:
R - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref.
R AMM TASK 73-21-60-400-001).
R (a) If the fault repeats on subsequent flights:
R - replace the CTL UNIT-THROTTLE, ENG1 (8KS1) (Ref. AMM TASK 76-R 11-19-000-042) and (Ref. AMM TASK 76-11-19-400-042).
R 1_ If the fault repeats on subsequent flights:
R - Do a check of the electrical wiring between the throttle
R control unit (8KS1) and the ECU (4000KS) (Ref. ASM 73-
25/12).
R a_ if damage is found:
R - replace or repair the above harness.
R b_ if nothing is found:
R - continue the troubleshooting as follows.
R 2_ Do a continuity and insulation check of this wiring. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 发动机控制(2)
