A. If the fault symptom is identified by the maintenance message:
TEMP SENSOR (6HA2)/BMC2 (1HA2)

Replace the SENSOR-EXCHANGER OUT TEMP, ENG 2 [6HA2] AMM 36-11-17-000-001 and AMM 36-11-17-400-001.

Subtask 36-11-00-810-432-A ** ON A/C NOT FOR ALL

B. If the fault continues:
(1) Do a check for ground for Exchanger Outlet Temperature-Sensor (6HA2) at pin G/2 of the BMC2 (1HA2).
(a) If there is no ground:
1 Do a check of the wiring from BMC2 (1HA2) pin G/2 and the ground terminal ASM 361102.
2 If you find damage in the wiring:
a Repair or replace the wiring .
(b) If there is ground:
1 Do a check of the wiring from Exchanger Outlet Temperature-Sensor (6HA2) pin A/1 and A/2 to BMC2 (1HA2) pin AA/2C and AA/2B ASM 361102.
2 If you find damage in the wiring:
a Repair or replace the wiring .

Subtask 36-11-00-810-419-A ** ON A/C NOT FOR ALL

C. If the fault continues:

Replace the BMC-2 [1HA2] AMM 36-11-34-000-001 and AMM 36-11-34-400-001.

Subtask 36-11-00-710-463-A ** ON A/C NOT FOR ALL

D. After the subsequent flight, make sure that the fault does not continue.
