4. Fault Isolation
_______________
A. If the test gives the maintenance message EIU (ARINC), J3:
- do a visual check of the connector J3 at the ECU (4000KS) for integrity (Ref. ASM 73-25/10).
(1) If the fault continues do a check of the status of circuit breakers 2KS2 and 4KS2 (Ref. ASM 73-25/05).
(a) If the circuit breakers 2KS2 and 4KS2 are closed:
- do a check for 28VDC at EIU 2 pins AC/9, 11.
1 If there is 28VDC:
_
- replace the EIU-2 (1KS2) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
2 If there is not 28VDC:
_
- do a check of the wiring between the circuit breakers 2KS2 and 4KS2 and the EIU 1 pins AC/9, 11.
- if there is no continuity:
- repair the wiring.
- if there is continuity:
- replace the ENGINE/2/FADEC A/AND EIU 2 (2KS2) and/or ENGINE/ENG2/FADEC B (4KS2).
(b) If the circuit breakers 2KS2 and/or 4KS2 are open:
- close them.
1 If they trip again:
_
- replace the EIU-2 (1KS2) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
a If the fault continues:
_
- do a check of the wiring for short to ground between the circuit breakers 2KS2 and/or 4KS2 and the EIU 1.
- if the wiring is not correct:
- repair it.
- if the wiring is correct:
- replace the ENGINE/2/FADEC A/AND EIU 2 (2KS2) and/or ENGINE/ENG2/FADEC B (4KS2).
(2) If the fault continues:
- replace the harness J3.
(3) If the fault continues:
- replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
B. Do the test given in Para. 3.A.
