(1) If the resistance values are out of the specified limits:
- replace the SENSOR-DUCT TEMPERATURE,AFT CABIN (17HK) (Ref. AMM TASK 21-63-15-000-001) and (Ref. AMM TASK 21-63-15-400-001).
(2) If the resistance values are in the specified limits:
- do a check and repair the wiring (Ref. ASM 21-63/03) from:
- the SENSOR-DUCT TEMPERATURE,AFT CABIN (17HK) to the ZC (8HK) and,
- the SENSOR-DUCT TEMPERATURE,AFT CABIN (17HK) to ground.
(3) If the fault continues:
- do a check that the resistance of the AFT cabin-duct overheat sensor (20HK) measured between connector A/A and A/B is in these limits (Ref. ASM 21-63/03):

(a) If the resistance values are out of the specified limits:
- replace the SENSOR-DUCT TEMPERATURE,AFT CABIN (20HK) (Ref. AMM TASK 21-63-18-000-001) and (Ref. AMM TASK 21-63-18-400-001).

(5) If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-63/03) from:
- the VALVE-TRIM AIR,AFT CABIN (13HK) to the ZC (8HK) and,
- the VALVE-TRIM AIR,AFT CABIN (13HK) to ground.
(6) If the fault continues:
- replace the VALVE-PRESSURE REGULATING (14HK) (Ref. AMM TASK 21-63-52-000-001) and (Ref. AMM TASK 21-63-52-400-001).
(7) If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-63/03) from:
- the VALVE-PRESSURE REGULATING (14HK) to the ZC (8HK) and,
- the VALVE-PRESSURE REGULATING(14HK) to ground.
(8) If the fault continues:
- replace the CONT-ZONE TEMPERATURE (8HK) (Ref. AMM TASK 21-63-34-000-001) and (Ref. AMM TASK 21-63-34-400-001).
B. If the test gives the maintenance message TEST OK, but on the ECAM upper DU the warning COND AFT CAB DUCT OVHT comes on:
- do a check of the AFT cabin-duct inlet temperature on the ECAM COND page.
(1) If the temperature is below 70 Deg.C:
- replace the SENSOR-DUCT OVHT TEMPERATURE,AFT CABIN (20HK) (Ref. AMM TASK 21-63-18-000-001) and (Ref. AMM TASK 21-63-18-400-001).
C. Do the test as given in the Para. 3.A.
