3. Fault Confirmation
Subtask 73-13-00-710-060-A ** ON A/C NOT FOR ALL
A. Do an engine run to idle to confirm repair of this fault AMM 71-00-00-860-822 or AMM 71-00-00-860-823.
   (1) Shutdown the engine AMM 71-00-00-860-814.
   (2) On MCDU screen, make sure that the fault is not displayed on ground scan report.
NOTE: The Electronic Engine Control (EEC) has detected that the fuel temperature reading from the Return To Tank (RTT) fuel temperature sensor has exceeded its high temperature limits. The RTT fuel temperature sensor is integral in the RTT valve. The RTT valve is located on the thermal management system manifold at the 8 o'clock position aft of the main gearbox.
4. Fault Isolation
WARNING: BE CAREFUL WHEN YOU DO WORK ON THE ENGINE AFTER SHUTDOWN. THE ENGINE CAN STAY HOT FOR A LONG TIME. IF YOU DO NOT OBEY THIS WARNING, INJURY CAN OCCUR.
WARNING: REFER TO THE MSDS FOR ALL MATERIAL USED AND THE MANUFACTURER'S SAFETY INSTRUCTIONS FOR ALL EQUIPMENT USED. IF YOU DO NOT OBEY THIS WARNING, INJURY CAN OCCUR.
CAUTION: MAKE SURE YOU REMOVE ELECTRICAL POWER FROM THE EEC BEFORE YOU REMOVE THE ELECTRICAL CONNECTORS. IF YOU DO NOT OBEY THIS INSTRUCTION, DAMAGE TO THE EEC CAN OCCUR.
Subtask 73-13-00-810-060-A ** ON A/C NOT FOR ALL
