R A. To Confirm the Fault
R (1) Do a read out of the POST FLIGHT and/or LAST LEG REPORT.
R (2) Do the power-up (BITE) test of the cargo compartment heating R controller (Ref. AMM TASK 21-43-00-740-002). R
4. Fault Isolation

R A. If the conditions which follow occur:
R - the POST FLIGHT and/or the LAST LEG REPORT gives the maintenance
R message AFT DUCT TEMP SENSOR and,
R on the lower ECAM display unit COND page the AFT duct temperature shows
R amber XX:
R
- replace the SENSOR-DUCT TEMP (13HC) (Ref. AMM TASK 21-43-15-000-001) and (Ref. AMM TASK 21-43-15-400-001).
