Troubleshooting Recommendations:

  1. With the left engine fire handle not pulled, select the FMQGC A(B)-CH A (B) ENGINE/APU FIRE SHUTOFF VALVE CONTROL page via CAIMS System Diagnostics, make sure the result that follow are met.

      Reference Status
      LEFT ENGINE FIRE HANDLE PULLED NOT PULLED
      LEFT ENG FEED VALVE OPEN STATUS OPEN
      LEFT ENG FEED VALVE CLOSED STATUS NOT CLOSED

    1. If all the above status are met, go to step 3.
    2. If the LEFT ENG FEED VALVE OPEN STATUS is shown as NOT OPEN, go to step 6.
    3. If the LEFT ENG FEED VALVE CLOSED STATUS is shown as CLOSED, go to step 9.
    4. If the LEFT ENGINE FIRE HANDLE PULLED is shown as PULLED, continue with next step.

  2. Perform wiring check (short to ground = fail) between the left engine fire handle (A209P1) and FMQGC (A47AP1).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, go to step 12.

  3. With the left engine fire handle pulled, select the FMQGC A (B)-CH A (B) ENGINE/APU FIRE SHUTOFF VALVE CONTROL page via CAIMS System Diagnostics, make sure the result that follow are met.

      Reference Status
      LEFT ENGINE FIRE HANDLE PULLED PULLED
      LEFT ENG FEED VALVE OPEN STATUS NOT OPEN
      LEFT ENG FEED VALVE CLOSED STATUS CLOSED

    1. If the above status are met, go to step 13.
    2. If the LEFT ENG FEED VALVE CLOSED STATUS is shown as NOT CLOSED, go to step 6.
    3. If the LEFT ENG FEED VALVE OPEN STATUS is shown as OPEN, go to step 9.
    4. If the LEFT ENGINE FIRE HANDLE PULLED is shown as NOT PULLED, continue with next step.
      NOTE: Push and hold the manual override pushbutton to unlock the left engine fire handle.

  4. Perform wiring check (Open to ground = fail) between the left engine fire handle (A209P1) and ground stud (GS527).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  5. Perform wiring check (Open to ground = fail) between the left engine fire handle (A209P1) and FMQGC (A47AP1).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, go to step 12.

  6. Check for 28 VDC at the left engine fuel shut-off valve (L38P1).

    1. If voltage is there, go to step 10.
    2. If voltage is not there, continue with next step.

  7. Perform wiring check between the left engine fire handle (A209P1) and left engine fuel shut-off valve (L38P1).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  8. Perform wiring check between the DCPC (A63P3) and the left engine fire handle (A209P1).

  9. Perform wiring check between the left engine fuel shut-off valve (L38P1) and FMQGC (A47AP1).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  10. Swap the Left engine feed shutoff actuator with right engine feed shut-off actuator.

    1. If system checks are good, replace left engine feed shut-off actuator and do close out.
    2. If fault remains, continue with next step.

  11. Swap the Left engine feed shut-off valve with Right engine feed shut-off valve.

    1. If system checks are good, replace Left engine feed shut-off valves and do close out.
    2. If fault remains, go to step 13.

  12. Swap the left engine fire handle with right engine fire handle.

    1. If system checks are good, replace left engine fire handle and do close out.
