3. Fault Confirmation
Subtask 75-41-00-710-064-A ** ON A/C NOT FOR ALL

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) AMM 73-25-34-710-040.

Subtask 75-41-00-710-064-B ** ON A/C NOT FOR ALL

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) AMM 73-25-34-710-043.

4. Fault Isolation
Subtask 75-41-00-810-057-A ** ON A/C NOT FOR ALL

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. TSM TASK 75-41-00-810-806) for failure message CHECK HOT AIR LEAKS (TSM CFDS chapter 36-22).

(1) If nothing is confirmed:

replace the SENSOR-TEMP, ENG 2 NACELLE [13KS2] AMM 75-41-15-000-040 and AMM 75-41-15-400-040.

(2) If the fault continues:

do a check of the electrical wiring between the EIU-2 [1KS2] and the nacelle temperature sensor (13KS2) ASM 732507, 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-2 AMM 73-25-34-000-040 and AMM 73-25-34-400-040.

Subtask 75-41-00-810-057-B ** ON A/C NOT FOR ALL

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. TSM TASK 75-41-00-810-806) for failure message CHECK HOT AIR LEAKS (TSM CFDS chapter 36-22).

(1) If nothing is confirmed:

replace the SENSOR-TEMP, ENG 2 NACELLE [13KS2] AMM 75-41-15-000-041 and AMM 75-41-15-400-041.

(2) If the fault continues:

do a check of the electrical wiring between the EIU-2 [1KS2] and the nacelle temperature sensor (13KS2) ASM 732507, 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-2 AMM 73-25-34-000-040 and AMM 73-25-34-400-040.

Subtask 75-41-00-710-065-A ** ON A/C NOT FOR ALL

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.
