Ge ne ral . A. The Fault Fault Isolation Isolation Manual Manual contains contains procedures procedures that provide provide instructions instructions to isolate fault conditions that result in a fault message being sent by the FADEC. B. The document document is divided divided into into seven seven fault isolati isolation on procedur procedures: es: (1) Fault Isolation 001: Provides Provides general scope on the whole procedure and explains how to use it when a fault message appears, provides a description of six fault message categories, provides some general fault isolation instructions, specifies tools, equipment and consumable materials utilized during a fault isolation, and contains two tables of all FADEC faults listed both ways: in Fault Code order - Table 101, and CMC Message alphabetical order - Table 102. (2) Fault Isolation 002-007: 002-007: Deal with fault isolation procedures procedures corresponding to six categories of FADEC faults. Each fault isolation procedure contains general information on its contents, how-to-use instructions, two tables of faults, listed the same way as in this procedure: in Fault Code order - Table 101, and CMC Message alphabetical order - Table 102, and troubleshooting procedures relevant to the faults. (3) Fault Isolation 008: Deal with "Non-FADEC" "Non-FADEC" fault isolation procedures. procedures. C. FADEC FADEC Fault Fault Mess Message age Cate Categor gories ies: : (1) In-Flight Warning: Warning: Indicates fault that requires pilot action or notification. Sent to the cockpit CAS messages or icons on the EICAS displays. Refer to TASK 72-00-00-810-802 (72-00-00, Fault Isolation 002). (2) No Dispatch: Dispatch is not permitted with message message present. Message can be caused by a single indicated fault or a combination of short and/or long-term faults. Refer to TASK 72-00-00-810-803 (72-00-00, Fault Isolation 003). (3) Short-Term Dispatch: Dispatch: Dispatch is permitted with a short-term fault(s) fault(s) present. The permitted dispatch interval for these faults is 150 flight hours. The indicated fault must be fixed/cleared before 150 flight hours expires. Message is displayed on EICAS. Refer to TASK 72-00-00-810-804 (72-00-00, Fault Isolation 004). (4) Long-Term Dispatch: Dispatch: Dispatch is permitted with long-term long-term fault(s) present. Correct all long-term faults on a periodic basis. The time interval approved for this periodic maintenance is less than or equal to 750 flight hours. Refer to TASK 72-00-00-810-805 (72-00-00, Fault Isolation 005). (5) Economic Dispatch: Dispatch: Dispatch is permitted with no time limit. Refer to TASK 72-00-00-810-806 (72-00-00, Fault Isolation 006). (6) Maintenance Information Information Messages: Can only be seen on the CMC. Refer to TASK 72-00-00-810-807 (72-00-00, Fault Isolation 007). D. Special troubleshooting troubleshooting procedures corresponding corresponding to the Fault Fault Message Message Categories are defined as subtasks in TASK 72-00-00-810-802 (72-00-00, Fault Isolation 002) thru TASK 72-00-00-810-807 (72-00-00, Fault Isolation 007).

This part defines the steps necessary to prove that the fault has been corrected. 2. How-to How-to-Us -Use e Inst Instru ructi ctions ons. . A. Read and follow General Fault Isolation Isolation Instructions Instructions described described in in paragraph paragraph 3. B. Having the Fault Code and/or CMC Message of of the fault fault under investigation investigation find appropriate Fault Message Category and Fault Isolation Subtask number in Table 101 - using the Fault Code, or in Table 102 - using the CMC Message. C. Go to the appropriate appropriate Fault Isolation Isolation corresponding corresponding to the Fault Fault Message Message Category and find the Fault Isolation Procedure that describes actions to isolate and correct the fault. D. Follow the instructions instructions in each each procedure procedure to isolate isolate the the fault. Each fault message includes instructions that can vary depending on which FADEC channel sent the message. Make sure that you follow the instructions for the FADEC channel (A or B) that sent the fault message when applicable. 3. General General Fault Fault Isolat Isolation ion Instruct Instructions ions. . A. Record all fault messages messages before before you do maintenance maintenance on the engine, engine, or before before you remove the engine from the aircraft. Refer to the AMM for operation of the EICAS and the CMC. Note the engine and FADEC designations. B. Some troubleshootin troubleshooting g procedures procedures require require special special evaluation engine runs in addition to the initial evaluation provided in particular subtasks. If the special evaluation engine run is required, the run procedure will be provided within the Fault Isolation Procedure. C. Some faults faults may require checking of electrical electrical characterist characteristics ics of possible defective components. D. Replace all all components components that fail a required check. Turn Turn off the the appropriate appropriate aircraft circuit breakers, refer to the AMM, and then re-power the FADEC and clear the faults. If faults are no longer present, do the necessary engine checks for replacement of that component. (1) Because some fault messages are only sent during engine operation, operation, a confirmation that a fault has been corrected can require engine operation, as instructed in the specific isolation procedure, to do the GE PROPRIETARY INFORMATION - Not to be used, disclosed to others or reproduced without the express written consent of GE.

check. (2) Because the FADEC channel channel and the igniters change change with each engine start, more than one engine start can be necessary to confirm that an engine start fault has been corrected. Refer to the engine operational check procedure. (3) Because some test faults (i.e., overspeed overspeed and EDP relay test faults) are stored to FADEC memory until the test is passed, multiple starts, as instructed in the specific isolation procedure, can be necessary to clear the fault after replacement of the component. E. Swapping of the FADEC harnesses for "XXX "XXX SENSOR SENSOR RANGE FAULT" faults. (1) The first step for "XXX SENSOR SENSOR RANGE FAULT" faults in the Fault Fault Isolation Procedure is to decide, using your judgment, whether the probability of a FADEC fault is significant enough to be taken into account as an actual fault cause. If so, perform the swapping of the FADEC harnesses according to the following procedure: (a) Turn off 400 Hz power to the FADEC by pulling pulling the appropriate aircraft circuit breakers. Refer to the AMM. (b) Disconnect the FA FADEC-side DEC-side P3 and P4 connectors connectors and swap the W3 (yellow) cable and the W4 (blue) cable. (c) Re-power the FADEC. 1
If the the fault fault is now now detec detected ted on the the oppos opposite ite channel channel (the fault fault switches channels), the defect is in the component or the cable associated with the original fault channel. Continue with the Fault Isolation Procedure at the subsequent step.
2
If the the fault fault remai remains ns on the the same same chan channel nel (th (the e fault fault does does not not switch channels), the defective component is the FADEC. Replace the FADEC. Refer to: FADEC Removal, AMM TASK 73-21-01-000-801-A. 73-21-01-000-801-A. FADEC Installation, AMM TASK 73-21-01-400-801-A.
