- Standard nozzle configuration is identified by a smooth conical exit surface
- Core chevron nozzle configuration is identified by 8 chevrons (triangular) around the circumference of the exit surface (SB RA32078-118).
(1) If a standard nozzle configuration is physically installed:
- On the left or right MCDU, get access to the ENGINE MAIN MENU screen.
- Push the line key (3L) adjacent to the LRU IDENT REPORT :

- Replace the J14 Identification connector (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002) or Do Re-programming of the Identification Connector (Push-pull design only) to a standard nozzle configuration (Ref. AMM TASK 73-21-90-860-001).
(b) If the MCDU screen indicates CCNECU Y and CCNIDP N:
- Do a configuration change of the Core Chevron Nozzle status change on LRU IDENT REPORT (Ref. AMM TASK 73-21-60-740-005).
(c) If the MCDU screen indicates CCNECU N and CCNIDP N:
- replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
(2) If a core chevron nozzle configuration is physically installed:
- On the left or right MCDU, get access to the ENGINE MAIN MENU screen.
- Push the line key (3L) adjacent to the LRU IDENT REPORT:
(a) If the MCDU screen indicates CCNECU Y and CCNIDP N:
- Replace the J14 Identification connector (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002) or Do Re-programming of the Identification Connector (Push-pull design only) to a core chevron nozzle configuration (Ref. AMM TASK 73-21-90-860-001).
(b) If the MCDU screen indicates CCNECU N and CCNIDP Y:
- Do a configuration change of the Core Chevron Nozzle status on LRU IDENT REPORT (Ref. AMM TASK 73-21-60-740-005).
(c) If the MCDU screen indicates CCNECU Y and CCNIDP Y:
- replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
