B. If the APU GND SCANNING menu gives the maintenance message:
IGV ACTUATOR (8014KM)
associated with Fault Code Number (FCN) 82
- do a check for damage/contamination of electrical connector P21 of the IGV ACTUATOR (8014KM)
(1) If the electrical 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 2 and pin 5 of the IGV ACTUATOR (P21).
(a) If the resistance is not between 10 Ohms and 100 Ohms:
- replace the IGV ACTUATOR (8014KM) (Ref. AMM TASK 49-23-51-000-004) and (Ref. AMM TASK 49-23-51-400-004).
(b) If the resistance is between 10 Ohms and 100 Ohms:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/E11,E12 to the IGV ACTUATOR (8014KM) P21/2,5 (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).

_______________ R **ON A/C 001-049, 101-105, 107-107, 151-154, 201-207,
A. If the APU GND SCANNING menu gives the maintenance message:
FUEL CONTROL UNIT P19
associated with Fault Code Number (FCN) 51 or 52
- do a check for damage/contamination of electrical connector P19 of the FUEL CONTROL UNIT (P19)
(1) If the electrical connector P19 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 5 of the FUEL CONTROL UNIT (P19).
(a) If the resistance value is not between 72 Ohms to 200 Ohms:
- replace the FUEL CONTROL UNIT (P19) (Ref. AMM TASK 49-32-11-000-003) and (Ref. AMM TASK 49-32-11-400-003).
(b) If the resistance value is between 72 Ohms to 200 Ohms:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/C3,C4 to the FUEL CONTROL UNIT (P19) P19/4,5 (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).
