- at the electrical connector (23HKA) do a check for a short circuit between:
* pins D and E and,
* GND and pins D and E.
(a) If there is no short circuit connect the electrical connector (23HKA).
(b) If there is a short circuit repair the related wiring between:
* connector (23HKA) pin D and ZC connector (8HKAA) pin 8K,
* connector (23HKA) pin E and ZC connector (8HKAA) pin 8J.
- connect the electrical connector (23HKA).
(9) If the fault continues:
- disconnect the electrical connector (24HKA) from the SENSOR-MIXER UNIT TEMPERATURE COCKPIT (24HK).
- at the electrical connector do a check for a short circuit between:
* pins C and D and,
* GND and pins C and D.
(a) If there is no short circuit connect the electrical connector (24HKA).
(b) If there is a short circuit repair the related wiring between:
* connector (24HKA) pin C and ZC connector (8HKAA) pin 8H,
* connector (24HKA) pin D and ZC connector (8HKAA( pin 8G.
- connect the electrical connector (24HKA).
(10) If the fault continues:
- disconnect the electrical connector (25HKA) from the SENSOR-MIXER UNIT TEMPERATURE CABIN (25HK).
- at the electrical connector (25HKA) do a check for a short circuit between:
* pins C and D and,
* GND and pins C and D.
(a) If there is no short circuit connect the electrical connector (25HKA).
(b) If there is a short circuit repair the related wiring between:
* connector (25HKA) pin C and ZC connector (8HKAA) pin 10H,
* connector (25HKA) pin D and ZC connector (8HKAA) pin 10G.
- connect the electrical connector (25HKA).
- install the CONT-ZONE TEMPERATURE (8HK). (Ref. AMM TASK 21-63-34-000-001).
- on the circuit breaker panel 122VU close the CBIs 1HK (V17), 2HK (V18), 3HK (V19) and 4HK (V20).
B. Do the test as given in the Para. 3.A.

3. Fault Confirmation
__________________
A. Functional Test of the Cockpit Temperature Control
(1) Do the pre-conditioning through the HP ground connection (Ref. AMM TASK 12-33-21-618-001).
(2) With your hand or a piece of paper do a check for air flow at the cockpit air-outlets.
4. Fault Isolation
_______________
A. If there is not a sufficient airflow from the cockpit air-outlets do the steps which follow:
(1) Do a check of the belly-fairing blowout-panel.
- If the belly-fairing blowout panel is open, then close it.
(2) Do a detailed visual inspection of the bellows between the air-pack 1 outlet and the mixer unit (Ref. AMM TASK 21-52-00-200-011).
(3) Replace the bellows if nessesary. NOTE : If the bellows are damaged, do a detailed visual inspection of
____ the flap of the pack 1 downstream check-valve (15HM)for condition and operation (Ref. AMM TASK 21-52-43-210-001).
