ASM 21-63/02).
(3) If the fault continues:
- do the trouble shooting procedures for the zone cont electrical component with short circuit (Ref. TASK 21-63-00-810-827).
R B. If the test gives the maintenance message NO 28V ON ZONE MAIN:
- do a check and repair the wiring between: ZC (8HK) connector AC/10 and CB (3HK), ZC (8HK) connector AC/8 and GND (Ref. ASM 21-63/01).
R C. If the test gives the maintenance message NO 28V ON ZONE SECD:
- do a check and repair the wiring between: ZC (8HK) connector AC/9 and CB (4HK), ZC (8HK) connector AC/7 and GND (Ref. ASM 21-63/01).
R D. Do the test as given in the Para. 3.A.

A. Confirmation of the Fault
(1) 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.
(2) Do a read out of the POST FLIGHT REPORT and the PREVIOUS LEG REPORT.

A. If the test gives the maintenance message TEST OK, but the POST FLIGHT REPORT and the PREVIOUS LEG REPORT give the maintenance message TRIM VALVE CKPT:
- replace the TRIM VALVE CKPT (11HK) (Ref. AMM TASK 21-63-51-000-001) and (Ref. AMM TASK 21-63-51-400-001).
B. If the test gives the maintenance message TRIM VALVE CKPT:
- replace the TRIM VALVE CKPT (11HK) (Ref. AMM TASK 21-63-51-000-001) and (Ref. AMM TASK 21-63-51-400-001).
(1) If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-63/02) from:
- the TRIM VALVE CKPT (11HK) to the ZC (8HK) and,
- the TRIM VALVE CKPT (11HK) to ground.
C. If the test gives the maintenance message TEST OK, but the cockpit trim-air valve symbol on the ECAM COND page is replaced by amber XX:
- replace the CONT-ZONE TEMPERATURE (8HK) (Ref. AMM TASK 21-63-34-000-001) and (Ref. AMM TASK 21-63-34-400-001).
