E. If the fault continues:
(1) Disconnect the electrical connector (7560VC/A)
(Ref. AMM TASK 21-61-16-000-001).
- make sure that the electrical connector is clean and in the correct condition.
- at the electrical connector (7560VC) do a check for 15VDC from the pack controller primary channel between,
* pins A and C (+15VDC) and,
* pins D and C (-15VDC).
(a) If the voltage is correct:
- replace the SENSOR-PACK INLET PRESSURE (36HH) (Ref. AMM TASK 21-61-16-000-001) and, (Ref. AMM TASK 21-61-16-400-002).
(2) If the fault continues:
- remove the CONTROLLER-PACK 2 TEMP (27HH)
(Ref. AMM TASK 21-61-34-000-001),
- disconnect the electrical connector (31HH/A) from the SENSOR-WATER EXTRACTOR TEMPERATURE (31HH),
- at the electrical connector (31HH/A) do a check for a short circuit between,
* pins E and F and,
* GND and pins E and F.
(a) If there is no short circuit connect the electrical connector (31HH/A).
(b) If there is a short circuit repair the related wiring between,
* connector (31HH/A) pin E and PC 2 connector (27HH/AA) pin 14A,
* connector (31HH/A) pin F and PC 2 connector (27HH/AA) pin 14B.
- connect the electrical connector (31HH/A).
(3) If the fault continues:
- disconnect the electrical connector (28HH/A) from the ACTUATOR-AIR INLET FLAP (28HH),
- at the electrical connector (28HH/A) do a check for a short circuit between,
* pins A and B, A and C, B and C and,
* GND and pins A, B and C.
(a) If there is no short circuit connect the electrical connector (28HH/A).
(b) If there is a short circuit repair the related wiring between,
* connector (28HH/A) pin A and PC 2 connector (27HH/AA) pin 11D,
* connector (28HH/A) pin B and PC 2 connector (27HH/AA) pin 12A,
