(2) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-008). NOTE : During the operational test of the APU, carefully examine the
____ fuel lines from the fuel control unit to the inlet guide-vane actuator:
- fuel leaks are not permitted, correct/replace as necessary.

A. Maintenance Action
(1) If the APU Last Leg Report gives the maintenance message:
IGV ACTR (8014KM):
Fault Code Number: 62 or 63
- do a check and repair the wiring from the ECB (59KD) AB/G8, G9, E12, E11, E8, E9 to the INLET GUIDE-VANE ACTUATOR (8014KM) P21/1, 2, 3, 4, 5, 6 (Ref. ASM 49-61/02).
(a) If the fault continues:
