R E. If the fault continues or if no leak is found:
R - Do a check for correct sealing and torquing of the fuel nozzles (Ref.
R AMM TASK 73-11-40-790-002). Fuel nozzles located on the top of the
R engine must be inspected first.
R (1) If the fault continues:
R - Do a resistance and insulation check of the electrical wiring
R between the nacelle temperature sensor (13KS1) and the EIU1 (1KS1)
R (Ref. ASM 73-25/07). The wiring resistance must be less than 2.4
R ohms. Repair the aircraft wiring as required.
R (2) If nothing is found:
R - replace the SENSOR-TEMP, ENG 1 NACELLE (13KS1) (Ref. AMM TASK 75-R 41-15-000-041) and (Ref. AMM TASK 75-41-15-400-041).
R (3) If the fault continues:
R - replace the EIU-1 (1KS1) (Ref. AMM TASK 73-25-34-000-040) and (Ref.
R AMM TASK 73-25-34-400-040) (less probable cause for this failure).
R F. Do a check that the fault does not continue on subsequent flight.
R (1) If the fault continues:
R
R - repeat the fault isolation procedure.

R NOTE : The following trouble shooting procedure must be completed at
____ R first opportunity not interfering with revenue service R operation within subsequent 10 days or 150 flight hours of R operation that follow the first exceedance of nacelle R temperature above 240 deg.C (464 deg.F) pending there is no R ECAM warning related to ENG2 FIRE LOOP A (B) FAULT.

4. Fault Isolation
_______________
R A. Do the following checks:
R NOTE : The maintenance message CHECK HOT AIR LEAKS ENG2 is generated and
____ R the advisory for nacelle temperature is flashing green on the R upper ECAM if the air temperature at the top of the core R compartment area is higher than 240 deg.C (464 deg.F).
R (1) Open both reverser cowls (Ref. AMM TASK 78-36-00-010-040).
R (2) Do a check for hot air leaks from the ECS:
R - make sure that the engine bleed ducts are in the correct condition
