(1) Not applicable, the fault is evident.
4. Fault Isolation
_______________
A. If the fault symptom is identified by the maintenance message:
TEMP SENSOR 6HA2:
-replace the SENSOR-EXCHANGER OUT TEMP, ENG 2 (6HA2) (Ref. AMM TASK 36-11-17-000-001) and (Ref. AMM TASK 36-11-17-400-001).
(1) If the fault continues:
-do a check for ground at pin A/1 of the exchanger outlet temperature-sensor of the engine 2.
(a) If there is no ground:
-do a check and repair the wiring between pin A/1 of the exchanger outlet temperature-sensor (6HA2) and the ground terminal (Ref. ASM 36-11/02).

(b) If there is ground:
-do a check and repair the wiring from the exchanger outlet temperature-sensor (6HA2) to the BMC2 (1HA2), pins A/2 and A/4 to pins AA/9B and AA/10B.
(2) If the fault continues:
-replace the BMC-2 (1HA2) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
B. After the subsequent flight, make sure that the fault does not continue.
