- do a check for damage/contamination of electrical connector P19 of the FUEL CONTROL UNIT (8022KM).
(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 (8022KM).
(a) If the resistance value is not between 72 Ohms to 200 Ohms:
- replace the FUEL CONTROL UNIT (8022KM) (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 (8022KM) 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).
