 3. Fault Confirmation
__________________
 A. Test
 (1) Do the operational test of the FADEC 2A on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).

 (2) Do the LRU identification through the MCDU (Ref. AMM TASK 73-21-60-740-006) and check that the data corresponds to the engine configuration.

 4. Fault Isolation
_______________
 A. If the test gives the maintenance message J14, ECU (ENG IDENT):
 - do a check for the loose or missing identification connector at the ECU2 connector J14 receptacle.
 (1) If the Service Bulletin 72-0340 is not incorporated, and if the fault continues:
 - reset the ECU2 (4000KS) as follows:
 (a) On the panel 115VU, set the ENG/MASTER 2 control switch (2KC) to OFF.

 (b) After 30 seconds, set the ENG/MASTER 2 control switch (2KC) to ON.
 1 If the fault continues:
_

 - replace the J14 engine identification connector (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002).
 a If the fault continues:
_

 - replace the ECU2 (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
 (2) If the Service Bulletin 72-0340 is incorporated, and if the fault continues:
 - read the LRU IDENTIFICATION report of the engine 2 (Ref. AMM TASK 73-21-60-740-006),

 - check that the engine identification connector installed on the engine meets the specific engine configuration (rating, N1 trim, system configuration, etc...).

 (a) If the rating identified on the LRU IDENTIFICATION report is incorrect:

 - replace the J14 engine identification connector (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002).

 (b) If other parameters than the rating identified on the LRU IDENTIFICATION report is (are) incorrect:

 - check for correct programming of the J14 engine identification connector (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002).
 1 If the fault continues:
_

 - replace the J14 engine identification connector (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002).
 a If the fault continues:
_

 - replace the ECU2 (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.
