3. Fault Confirmation __________________ A. Test ____ NOTE : This fault is generated if the installed engine thrust and/or bump rating is not correct. (1) On the MCDU, get the SYSTEM REPORT/TEST page (Ref. AMM TASK 31-32-00860-012). (a) Push the line key adjacent to the FADEC 1A(1B) for engine 1 or 2. (b) Push the line key adjacent to the LRU identification. (c) Check that both engines have the same thrust and bump rating (Ref. AMM TASK 73-21-60-400-001). 4. Fault Isolation _______________ A. Do this procedure: (1) If engines have not the same thrust and bump rating: - check engine configuration table to determine which rating is correct, and replace the Identification Connector (Ref. AMM TASK 73-21-90-000-002) and (Ref. AMM TASK 73-21-90-400-002). (2) If both engines thrust and bump rating are the same: - check that both engines match the A/C type configuration:
