A. Check/Test
(1) Get access to the AIDS parameters (ALPHA CALL UP) (Ref. AMM TASK 31-36-00-740-008).
(a) Record the parameter IGV (APU Inlet Guide Vanes)
- during APU start
and
- during APU operation.
(2) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-008).
NOTE : Make sure that the fuel supply to the APU is correct (Ref. AMM
____ TASK 28-22-00-710-002). If the fuel supply is not correct, do the trouble shooting of APU low fuel pressure (Ref. TASK 28-22-00-810-801).

_______________
A. If an APU auto shutdown occurs during the operational test of the APU and the APU SHUTDOWNS report gives the maintenance message:
0VERTEMPERATURE - INLET GUIDE VANE ACTR (8014KM)
and the IGV parameter is
72 deg (+/- 2 deg) during APU start sequence
and
82 deg during APU run (without load):
- replace the FUEL CONTROL UNIT (8022KM) (Ref. AMM TASK 49-32-11-000-002) and (Ref. AMM TASK 49-32-11-400-002).
(1) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-002) and (Ref. AMM TASK 49-61-34-400-002).
