3. Fault Confirmation
__________________
A. Test
(1) Check the Post Flight Report (PFR), crew report and do the operational test of the Engine Interface Unit (EIU) through the Centralized Fault Display System (CFDS) (Ref. AMM TASK 73-25-34-710-043).
4. Fault Isolation
_______________
A. If the maintenance message CHECK HOT AIR LEAKS is shown at the end of test or in the Post Flight Report (PFR) or if the crew reported that nacelle temperature was flashing on ECAM:
- do the relevant trouble shooting procedure (Ref. TASK 75-41-00-810-805) for failure message CHECK HOT AIR LEAKS (TSM CFDS chapter 36-22).
(1) If nothing is confirmed:
- replace the SENSOR-TEMP, ENG 1 NACELLE (13KS1) (Ref. AMM TASK 75-41-15-000-041) and (Ref. AMM TASK 75-41-15-400-041).
(2) If the fault continues:
- do a check of the electrical wiring between the EIU-1 (1KS1) and the nacelle temperature sensor (13KS1) (Ref. ASM 73-25/07), wiring resistance must be lower than 2.4 ohms.

(a) Check the electrical connectors for absence of contamination, corrosion or loose pins:
- clean or repair aircraft wiring as required.
(3) If the fault continues:
- replace the EIU-1 (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
B. Do the test given in Para. 3.A.
(1) No additional maintenance action is required if the fault is not confirmed.
(2) Repeat the fault isolation procedure if the fault continues.
