A. Maintenance Action
(1) If there is a CLASS 2 Fault Message
WRG: APU LOAD VALVE
with the LRU TROUBLE SHOOT DATA menu information:
LOAD VALVE OPEN SIGNAL SHOWS CIRCUIT FAILURE Fault Code Number: 138 and the Bleed Control Valve indication is replaced by amber XX:
- do the trouble shooting of the Load Control Valve (8050KM) (Ref. TASK 49-00-81-810-864).
