(a) If the resistance values are out of the specified limits:
- 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 values are in the specified limits:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/A10,A11 to FUEL CONTROL UNIT (P19) P19/2,3 (PRIMARY FCU RESOLVER) and the ECB (59KD) AB/H10,B5,B6 to FUEL CONTROL UNIT (P19) P19/12,10,11 (SECONDARY FCU RESOLVER)

NO ACCELERATION
FUEL CONTROL UNIT P19
associated with Fault Code Numbers (FCN) 105, 106, 107 or 108
- 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 6 and pin 7 of the FUEL CONTROL UNIT (P19).
(a) If the resistance value is not between 20 Ohms and 100 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 in the specified limit:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/H11,G7 to the FUEL CONTROL UNIT (P19) P19/6,7 (Ref. ASM 49-61/01).
