 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 (6HA2)
 (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 th 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 and

 -
do a check and repair the wiring from the exchanger outlet temperature-sensor (6HA2) to the BMC1 (1HA1), pins A/4 and A/5 to pins AA/6D and AA/7D (Ref. ASM 36-11/01).

 (2)
 If the fault continues:

 -replace the BMC-2 (1HA2) and/or the BMC-1 (1HA1) (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.
