A. If the APU GND SCANNING menu gives the maintenance message:
IGV ACTUATOR P21
associated with Fault Code Number (FCN) 81
- do a check for damage/contamination of electrical connector P21 of the IGV ACTUATOR (P21).
(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 1 and pin 6 of the IGV ACTUATOR (P21).
(a) If the resistance value is not between 50 Ohms and 300 Ohms:
- replace the IGV ACTUATOR (P21) (Ref. AMM TASK 49-23-51-000-004) and (Ref. AMM TASK 49-23-51-400-004).
(b) If the resistance value is between 50 Ohms and 300 Ohms:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/E8,E9 to the IGV ACTUATOR (P21) P21/1,6 (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).
B. If the APU GND SCANNING menu gives the maintenance message:
IGV ACTUATOR P21
associated with Fault Code Number (FCN) 82
- do a check for damage/contamination of electrical connector P21 of the IGV ACTUATOR (P21).

(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 (P21) (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 (P21) P21/2,5 (Ref. ASM 49-61/02).
1 If the fault continues:

A. If the APU GND SCANNING menu gives the maintenance message:
IGV ACTUATOR (8014KM)
associated with Fault Code Number (FCN) 81
- 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 1 and pin 6 of the IGV ACTUATOR (8014KM).
