__________________
A. Do the operational test of the FADEC on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).
4. Fault Isolation
_______________
A. If the test gives the CFDS message ENG MSTR, HMU or MASTER LEVER, HMU:
- replace the EIU (1KS1) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
(1) If the fault continues: R - replace the CTL SW-ENG/MASTER 1 (3KC) on the 115VU (Ref. AWM 76-12-R 01).
(2) If the fault continues:
- replace the HMU (Ref. AMM TASK 73-21-10-000-002) and (Ref. AMM TASK 73-21-10-400-002).

R (3) If the fault continues:
R - do a check of the aircraft wiring between the pin AA/4E and AA/5A
R of EIU (1KS1) and the pin 2A and 2B of ENG/MASTER control switch
R (3KC).
R (a) If there is no continuity:
R - repair the above wiring (Ref. ASM 76-12/01)
R (4) If the fault continues:
R - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref.
