__________________
A. Test
(1) 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 maintenance message J14 (ID FAULT), ECU:
- Verify that the J14 Identification Connector (ID plug) is installed:
(1) If an ID plug is not installed:
- Install J14 Identification Connector (Ref. AMM TASK 73-21-90-400-002)
(2) If an ID plug is installed:
- verify that the ID plug is correct:
NOTE : The ID plug can be checked on the MCDU screen. Access
____ reporting functions, then select the LRU Identification screen.
Line 1 of the LRU Identification screen shows the engine model designation as "CFM56-5BX/ZZZ".
- The value of X represents the engine thrust rating
- If the value of X is equal to "X", the ID plug is invalid.

- replace the ID plug (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002)
(b) If the ID plug is valid:
- remove, clean, and reinstall the ID plug (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002)
- If the fault continues, replace the ID plug (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002).
(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.
