A. Test
(1) Not applicable.
4. Fault Isolation
_______________
A. If the fault is also present on engine 2:
- replace the CONT-ZONE TEMPERATURE (8HK) (Ref. AMM TASK 21-63-34-000-001) and (Ref. AMM TASK 21-63-34-400-001).
(1) If the fault is present on engine 2 only:
- do a check of the wiring between the EIU2 (1KS2) pins AA/2J, AA/2K and terminal block 1853VT and between the EIU2 (1KS2) pins AA/3J, AA/3K and terminal block 1862VT (Ref. AWM 73-25-20).
(a) If the wiring is not correct:
- Repair as required.
(b) If the wiring is correct:
- replace the EIU-2 (1KS2) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
