- do a check of the aircraft wiring from the ECB (59KD) AB/G8 to the IGV ACTUATOR (P21) P21/4 (Ref. ASM 49-61/01).
c If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).
(b) If the IGV linkage is damaged and/or does not move freely:
- replace the APU (4005KM) (Ref. AMM TASK 49-11-11-000-004) and (Ref. AMM TASK 49-11-11-400-004).

A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
NO ACCELERATION
CHECK IGV ASSEMBLY/IGV ACTUATOR (8014KM)
associated with Fault Code Number (FCN) 83
- do a check for damage/leakage of the fuel supply and return lines of the IGV ACTUATOR (8014KM)
(1) If there is damage/leakage in the fuel supply and return lines:
- do a repair
(2) If the fuel supply and return lines are OK:
- do a check for damage of the IGV linkage:
(a) If the IGV linkage is OK:
- do a check for damage/contamination of the electrical connector P21 of the ICV ACTUATOR (8014KM)
1 If the electrical connector P21 is damaged/contaminated:
_
- do a repair/cleaning. 2 If the electrical connector P21 is OK:
_
- use a multimeter to do the resistance a check across pin 4 and pin 10 of the IGV ACTUATOR (8014KM).
a If the resistance value is < 100 kOhms:
_
- replace the IGV ACTUATOR (8014KM) (Ref. AMM TASK 49-23-51-000-004) and (Ref. AMM TASK 49-23-51-400-004).
