Troubleshooting Recommendations:

  1. Perform a deactivation of the thrust reverser.
  2. Open the cowls.

    1. If the fault message is not active, go to step 6.
    2. If the fault message is active, continue with next step.

  3. Replace the FMU.

    1. If system checks are good, go to step 6.
    2. If fault remains, continue with next step.

  4. Wet motor the engine.

    1. If the fault message is not active, go to step 6.
    2. If the fault message is active, continue with next step.

  5. Replace the EEC 1.
  6. Close the cowls and perform a activation of the thrust reverser.
  7. Do close out.
