3. Fault Confirmation
__________________
 A. Do the operational test of the cockpit and cabin temperature-control system with CFDS/MCDU (Ref. AMM TASK 21-63-00-710-004).
 NOTE : If a fault is detected, the ZC gives a fault code for shop
____ maintenance in addition to the related CFDS message(s). For detailed information see the applicable Page Block 301.
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message TEMP SENSOR L/H AND R/H MIXER:
 - replace the SENSOR-MIXER UNIT TEMPERATURE COCKPIT (24HK) (referred to as SENSOR (24HK)) (Ref. AMM TASK 21-63-16-000-001) and (Ref. AMM TASK 21-63-16-400-001),

 - replace the SENSOR-MIXER UNIT TEMPERATURE CABIN (25HK) (referred to as SENSOR (25HK)) (Ref. AMM TASK 21-63-16-000-001) and (Ref. AMM TASK 21-63-16-400-001).

 (1) If the fault continues:
 - do a check and repair the wiring (Ref. ASM 21-63/03) between: SENSOR (24HK) connector A/E and ZC (8HK) connector AA/8C, SENSOR (24HK) connector A/F and ZC (8HK) connector AA/8D, SENSOR (24HK) connector A/C and ZC (8HK) connector AA/8H,

_______________
 A. Make sure that:
 (1) For the cockpit temperature sensor 21HK:

 - the cockpit ceiling panel 211HC is flush with the temperature sensor housing (Ref. AMM TASK 25-13-41-400-001).

 - there is no gap between the ceiling panel and the temperature sensor housing.

 (2) For the cabin temperature sensors 22HK and 23HK:

 - the temperature-sensor air duct inlet-grill is correctly positioned in and over the air duct inlet (Ref. AMM TASK 25-24-41-400-001).
