Troubleshooting Recommendations:

  1. Perform a deactivation of the thrust reverser and open the cowls.
  2. Perform wiring checks between channel A P1062 and P1043.

    1. If wiring checks are not good, repair defective wiring as required and go to step 6.
    2. If wiring checks are good, continue with next step.

  3. Perform wiring checks between channel B P1061 and P1046.

    1. If wiring checks are not good, repair defective wiring as required and go to step 6.
    2. If wiring checks are good, continue with next step.

  4. Replace defective Fuel Temperature Transducer.
    NOTE: It is recommended that you replace the fuel temperature transducer (channel A or channel B) which gave the highest fuel temperature indication first.

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

  5. Replace Right EEC.
  6. Close the cowls and activate the thrust reverser.
  7. Do close out.
