-disconnect the LOOP CONTROLLER (9240SI) from the BMC2 connector
-do a visual inspection of the sensing elements and cables on the engine 2 pylon loop.
(a)
If a sensing element or cable is damaged:
-replace the sensing element or cable (Ref. AMM TASK 36-22-15-000-001) and (Ref. AMM TASK 36-22-15-400-001)
-disconnect the LOOP CONTROLLER (9240SI) from the BMC2 connector
-install the BMC2 (Ref. AMM TASK 36-11-34-400-001)
-refer to Para. 4.C.
(b)
If no sensing element is damaged:
-disconnect the connector between the cable 2HF2 and the sensing element 1HF2
-connect the LOOP CONTROLLER (9240SI) between the connector 1HA2-AA/6B and the ground
-do a check of the impedance read on the LOOP CONTROLLER (9240SI).
1_ If the impedance is less than 3 KOhms:
- replace the CABLE-CONNECTING, ENG 2 PYLON (2HF2) (Ref. AMM
TASK 36-22-15-000-001) and (Ref. AMM TASK 36-22-15-400-001)
- do a check of the impedance read on the LOOP CONTROLLER
(9240SI).
