2. Fault Confirmation
Subtask 28-21-00-710-083-B ** ON A/C NOT FOR ALL

A. Test
(1) No troubleshooting work steps are necessary.

NOTE: This is an instruction to tell Flight Crew to switch on the CTR TK pumps 1 and 2 because the ECAM system found (detected) they were not in operation when fuel remains in the related fuel-tank. The warning is only given in Flight Phases 2 and 6. If the center-tank fuel-pumps are not in operation the aircrafts total fuel load will not be used in the correct sequence. If this condition was to continue it would cause the FUEL-AUTO FEED FAULT warning to be given and the P/BSW-CTR TK/MODE SEL/AUTO (48QA), FAULT legend to come on (when AUTO has been selected).

3. Fault Isolation
Subtask 28-21-00-810-083-B ** ON A/C NOT FOR ALL
