- do an operational test of the engine interface unit and see if the "NO ZONE CONT DATA" message is shown (Ref. AMM TASK 73-25-34-710-043).
(a) If the message is shown:
- replace the CONT-ZONE TEMPERATURE (8HK) (Ref. AMM TASK 21-63-34-000-001) and (Ref. AMM TASK 21-63-34-400-001).
(b) If the message is not shown:
- replace the EIU-1 (1KS1) (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
(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.

Loss of the Zone Controller Data on the ARINC Bus from the EIU to the FADEC on Engine 2
1. Possible Causes
_______________
- EIU-2 (1KS2)
- harness J3 from the EIU-2 (1KS2) to the ECU (4000KS)
- CONT-ZONE TEMPERATURE (8HK)
- ECU (4000KS)

3. Fault Confirmation
__________________
A. Do the operational test of the FADEC 2B on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).
4. Fault Isolation
_______________
A. If the test gives the maintenance message ZC, EIU (ECSD), J3:
- do a check for open or short to ground at the pins AB/5A, 5C to pins J3/22, 23 of the harness J3 from the EIU-2 (1KS2) to the ECU (4000KS) (Ref. ASM 73-25/06).
(1) If the wiring is not correct:
- repair the above harness J3.
