201-210, Config-1 Aug 01/05 CES 1 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 APU GND SCANNING menu gives the maintenance message:
IGV ACTUATOR (8014KM)
associated with Fault Code Number (FCN) 110
- do a check for damage/contamination of electrical connector P21 of the IGV ACTUATOR (8014KM).
(1) If the electriacl connector P21 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector is OK:
- use a multimeter to do a resistance check across pin 4 and pin 7 of the IGV ACTUATOR (P21), pin 4 and pin 10 of the IGV ACTUATOR (8014KM) connector P21
(a) If the resistance is
< 15 Ohms (pin 4-7)
or
< 100K Ohms (pin 4-10):
R - replace the IGV ACTUATOR (8014KM) (Ref. AMM TASK 49-23-51-000-R 004) and (Ref. AMM TASK 49-23-51-400-004).
(b) If the resistance is
> 15 Ohms and < 100 Ohms (pin 4-7)
and
> 100K Ohms (pin 4-10):
- do a check and repair of the aircraft wiring between ECB (59KD) AB/G8,G9 and IGV ACTUATOR (P21) P21/4,7 and/or IGV ACTUATOR (P21) P21/10 and aircraft GND (Ref. ASM 49-61/02).
1 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).
