A. Test Do the operational test of the engine interface unit through the CFDS (Ref. AMM TASK 73-25-34-710-043).
4. Fault Isolation
_______________
A. If the test gives the maintenance message CHECK EIU 1 ARINC OUTPUT CIRCUIT TO 199VC OR EIU 1:
- do a check for 28VDC at EIU 1 pins AC/9, 11.
(1) If there is 28VDC:
- replace the EIU-1 (1KS1) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040) (Ref. ASM 73-25/05).
(2) If the fault continues:
- do a check and repair the wiring from the EIU 1 (1KS1) pins AB/5H, 5K to the first terminal block (Ref. ASM 73-25/06).
(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).
