(2) If the fault continues:
- do a check that the resistance of the compressor overheat sensor (35HH) measured between connector A/A and A/B is in these limits (Ref. ASM 21-61/02):
Temp (Deg.C) OHMS ---------------------------
+ 10 103.9 +/- 0.5
+ 20 107.8 +/- 0.5
+ 30 111.7 +/- 0.5
+ 50 119.4 +/- 0.5
+ 70 127.1 +/- 0.5
+ 100 138.5 +/- 0.5
(3) If the resistance values are out of the specified limits:
- replace the SENSOR-COMPRESSOR OVERHEAT (35HH) (Ref. AMM TASK 21-61-12-000-001) and (Ref. AMM TASK 21-61-12-400-001).
(4) 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.

(5) 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) Disconnect 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.

(1) If the resistance values are out of the specified limits:
- replace the SENSOR-COMPRESSOR TEMPERATURE (32HH) (Ref. AMM TASK 21-61-11-000-001) and (Ref. AMM TASK 21-61-11-400-001).
