(1) If the resistance values are out of the specified limits:
- replace the SENSOR-COMPRESSOR TEMPERATURE (12HH) (Ref. AMM TASK 21-61-11-000-001) and (Ref. AMM TASK 21-61-11-400-001).
(2) If the fault continues:
- do a check that the resistance of the compressor overheat sensor (15HH) measured between connector A/A and A/B is in these limits (Ref. ASM 21-61/04):

(a) If the resistance values are out of the specified limits:
- replace the SENSOR-COMPRESSOR OVERHEAT (15HH) (Ref. AMM TASK 21-61-12-000-001) and (Ref. AMM TASK 21-61-12-400-001).
(3) If the fault continues: Do the inspection of the delta P sense lines (Ref. AMM TASK 21-51-00-200-001).
(4) If the fault continues: Replace the SENSOR-PRESSURE (10HB) (Ref. AMM TASK 21-51-11-000-001) and (Ref. AMM TASK 21-51-11-400-001).
(5) If the fault continues:
(a) Swap the SDACIs (1WV1 and 1WV2).(Ref.AMM Task 31-55-34-401)
(b) If this action has solved the problem:
- replace the SDAC which formerly was SDAC#1.
(6) If the fault continues:
(a) Open the CBIs for the Pack Controller 1+2.
(b) Disconnect the Pack ControllerIs. ( Ref.AMM Task 21-61-34-401)
(c) Diconnect the electrical connectors at the FCV#1 (11HB) and FCV#2 (8HB). (Ref.AMM Task 21-51-51-401)
(d) Disconnect the SDAC#1.
(e) Do a check for GND at the SDAC#1 connector AA pin 10D.
(f) Do a check for GND at the SDAC#1 connector AA pin 13B. NOTE : There should be no GND contact

(g) If there is no GND contact, reconnect the SDAC#1.
(h) If there is GND contact do a check of the wiring and repair if nessesary.
